Background, aim, and scope
Many pollutants have received significant attention due to their potential estrogenic effect and are classified as endocrine disrupting compounds (EDCs). Because of possible ecological effects and increased attention for water reuse schemes, it is important to increase our understanding of the EDC removal capacities of various wastewater treatment systems. However, there has so far been little research on the fate and behavior of EDCs in stabilization pond systems for wastewater treatment, which represent an important class of wastewater treatment systems in developing countries because of their cost-effectiveness. The aim of this work is to study the fate and behavior of EDCs in algae and duckweed ponds. Because the synthetic hormone 17α-ethinylestradiol (EE2) and the natural hormones estrone (E1), as well as 17β-estradiol (E2), have been detected in effluents of sewage treatment plants and been suggested as the major compounds responsible for endocrine disruption in domestic sewage; E1, E2, and EE2 were therefore chosen as target chemicals in this current work. 相似文献2.

The past 50 years have seen rapid development of new building materials, furnishings, and consumer products and a corresponding explosion in new chemicals in the built environment. While exposure levels are largely undocumented, they are likely to have increased as a wider variety of chemicals came into use, people began spending more time indoors, and air exchange rates decreased to improve energy efficiency. As a result of weak regulatory requirements for chemical safety testing, only limited toxicity data are available for these chemicals. Over the past 15 years, some chemical classes commonly used in building materials, furnishings, and consumer products have been shown to be endocrine disrupting chemicals – that is they interfere with the action of endogenous hormones. These include PCBs, used in electrical equipment, caulking, paints and surface coatings; chlorinated and brominated flame retardants, used in electronics, furniture, and textiles; pesticides, used to control insects, weeds, and other pests in agriculture, lawn maintenance, and the built environment; phthalates, used in vinyl, plastics, fragrances, and other products; alkylphenols, used in detergents, pesticide formulations, and polystyrene plastics; and parabens, used to preserve products like lotions and sunscreens. This paper summarizes reported indoor and outdoor air concentrations, chemical use and sources, and toxicity data for each of these chemical classes. While industrial and transportation-related pollutants have been shown to migrate indoors from outdoor sources, it is expected that indoor sources predominate for these consumer product chemicals; and some studies have identified indoor sources as the predominant factor influencing outdoor ambient air concentrations in densely populated areas. Mechanisms of action, adverse effects, and dose–response relationships for many of these chemicals are poorly understood and no systematic screening of common chemicals for endocrine disrupting effects is currently underway, so questions remain as to the health impacts of these exposures. 相似文献

A workshop was held in Berlin September 12–14th 2012 to assess the state of the science of the data supporting low dose effects and non-monotonic dose responses (“low dose hypothesis”) for chemicals with endocrine activity (endocrine disrupting chemicals or EDCs). This workshop consisted of lectures to present the current state of the science of EDC action and also the risk assessment process. These lectures were followed by breakout sessions to integrate scientists from various backgrounds to discuss in an open and unbiased manner the data supporting the “low dose hypothesis”. While no consensus was reached the robust discussions were helpful to inform both basic scientists and risk assessors on all the issues. There were a number of important ideas developed to help continue the discussion and improve communication over the next few years. 相似文献

Background Different types of indicators have been developed to describe the impact of chemicals on society and environment. Due to
the high number of substances and their different types of use, most of these indicators are directed to specific areas of
interest – regarding workplace safety, environmental health or consumer health. They address a specific subset of chemicals
and can be used for monitoring enterprise-specific, national or international management measures.
Main Features A survey of existing indicators for chemicals has shown that indicators already exist for a remarkable number of problem
fields. As soon as the release and the environmental fate of chemicals are taken into account, the complexity of the approaches
increases considerably. The distinction between indicators for drivers, pressures, state, impacts and responses, as proposed
by the European Environmental Agency, supports the identification of proper indicators for a specific type of problem.
Discussion and Conclusions. No single indicator exists which is able to cover the whole range of chemicals and their applications. Several
indicator approaches cover at least a subset of the most relevant substances. If they are intended to be used for European
monitoring, robust data must be provided by EU Member States.
Chemicals in enterprises (ancillary inputs as well as process chemicals) are an important element of in-plant material flow
management – in terms of occupational safety and health as well as environmental protection. Existing indicators for hazardous
chemicals can be a valuable tool for process and product refinement regarding hazardous chemicals, especially for enterprises.
Outlook Indicators for production and impact of chemicals, as well as policy performance indicators, are essential elements in order
to monitor the management of chemicals. They have to be established for the national and for the EU level. 相似文献

We are happy and proud to announce that our book ‘Atmospheric Degradation of Organic Substances — Data for Persistence and
Long-range Transport’ (see pp. 143–144) has recently been published by Wiley-VCH [1]. It contains a critical compilation of
photo degradation rate constants and quantum efficiencies relevant for calculating the atmospheric persistence of volatile
and a few semi-volatile organic compounds. In addition to the data of nearly 1100 substances, the importance of persistence
in air and long-range transport potential is presented in two chapters from the point of view of chemicals legislation and
of atmospheric photochemistry. 相似文献

The principles of precaution and sustainability require more consideration in the assessment of environmental risks posed by chemicals and genetically modified organisms. Instead of applying risk reduction measures when there are serious indications for damage, full scientific certainty is often waited for before taking action. The precautionary principle particularly should be applied in those cases in which the extent and probability of damage are uncertain, e.g. in the case of persistent chemicals which are additionally bioaccumulative or highly mobile. Based on these principles, environmental action targets for risks associated with GMOs and chemicals can be developed. Risk management not only includes statutory measures but also instruments designed to influence behaviour indirectly are important to achieve the goals. Particularly for risks of GMOs which provoke fear, risk communication is important. Some rules to which attention should be paid in communication with the public are presented. 相似文献

Endocrine disrupters in the aquatic environment 总被引:1,自引:0,他引:1
Petra Stahlschmidt-Allner Bernhard Allner Jörg Römbke Thomas Knacker 《Environmental science and pollution research international》1997,4(3):155-162
Possible mechanisms to explain endocrine effects on reproduction and sex differentiation are presented for selected pharmaceuticals,
agrochemicals, industrial chemicals and plant sterols which are known to be present in the aquatic environment. Disruptions
of the hormonal coordination can be induced by xenobiotics on various levels of the hierachically organised endocrine system
of vertebrates. Phthalate plasticisers, for example, may disrupt the pituitary control of gonadal functions; prenatal/larval
exposure to synthetic estrogen impairs sex differentiation and neuroendocrine sexual determination of the central nervous
system; phenylurea herbicides block the androgen receptor; the biotransformation of weakly estrogenic plant sterol components
of paper mill wastewater (e.g. βsitosterol) may lead to androgenic compounds. The effect of hypolipidemic drugs on lipid homeostasis
(peroxysom proliferation) is transmitted via a receptor protein that seems to be closely related to the endocrine system both
functionally as well as phylogenetically; possible interferences with the neuroendocrine control of sex differentiation are
also discussed. In invertebrates, tributyltin is known to effect the biosynthesis of steroidal sexual hormones. PCBs are suspected
to be competitive inhibitors of the steroid catabolism.
In order to identify potential risks caused by chemicals to the reproductive capacities of aquatic animals and to the quality
of drinking water, methods should be established to detect endocrine disrupters at the various levels of the endocrine system. 相似文献

Background, Goals and Scope In response to concerns that have been raised about chemical substances that may alter the function of endocrine systems and
result in adverse effects on human health, an OECD initiative was undertaken to develop and validate in vitro and in vivo assays to identify chemicals that may interfere with endocrine systems of vertebrates. Here we report on studies that were
conducted to develop and standardize a cell-based screening assay using the H295R cell line to prioritize chemicals that may
act on steroidogenic processes in humans and wildlife. These studies are currently ongoing as part of the ‘Special Activity
on the Testing and Assessment of Endocrine Disruptors’ within the OECD Test Guidelines Program to review, develop, standardize,
and validate a number of in vitro and in vivo toxicological assays for testing and assessment of chemicals concerning their potential to interact with the endocrine system
of vertebrates.
Study Design Six laboratories from five countries participated in the pre-validation studies. Each laboratory tested the effects of three
model chemicals on the production of testosterone (T) and estradiol (E2) using the H295R Steroidogenesis Assay. Chemicals
tested were well described inducers or inhibitors of steroidogenic pathways (forskolin, prochloraz and fadrozole). All experiments
were conducted in 24 well plates following standard protocols. Six different doses per compound were analyzed in triplicate
per plate. A quality control (QC) plate was run in conjunction with the chemical exposure plate to account for inter-assay
variation. Each chemical exposure was conducted two or three times.
Results All laboratories successfully detected increases and/or decreases in hormone production by H295R cells after exposure to the
different model compounds and there was good agreement in the pattern of response for all groups. Forskolin increased both
T and E2 while fadrozole and prochloraz decreased production of both hormones. All chemicals affected hormone production in
a dose-dependent manner with the exception of fadrozole which caused maximum inhibition of E2 at the two least concentrations
tested. Some inter-laboratory differences were noted in the alteration of hormone production measured in chemically exposed
cells. However, with the exception of the production of T measured at one laboratory in cells exposed to forskolin, the EC50s calculated were comparable (coefficients of variation 34–49%) for all hormones.
Discussion and Perspectives The results indicated that the H295R Steroidogenesis Assay protocol was robust, transferable and reproducible among all laboratories.
However, in several instances that were primarily related to one laboratory there were unexplained minor uncertainties related
to the inter-laboratory hormone production variation. Based on the findings from this Phase 2 prevalidation study, the H295R
Steroidogenesis Assay protocol is currently being refined. The next phase of the OECD validation program will test the refined
protocol among the same group of laboratories using an extended set of chemicals (∼30) that will include positive and negative
chemical controls as well as a broad spectrum of different potential inducers and inhibitors of steroidogenic pathways.

Endocrine disruptors in bottled mineral water: total estrogenic burden and migration from plastic bottles 总被引:1,自引:1,他引:0
Martin Wagner Jörg Oehlmann 《Environmental science and pollution research international》2009,16(3):278-286
Background, aim, and scope Food consumption is an important route of human exposure to endocrine-disrupting chemicals. So far, this has been demonstrated
by exposure modeling or analytical identification of single substances in foodstuff (e.g., phthalates) and human body fluids
(e.g., urine and blood). Since the research in this field is focused on few chemicals (and thus missing mixture effects),
the overall contamination of edibles with xenohormones is largely unknown. The aim of this study was to assess the integrated
estrogenic burden of bottled mineral water as model foodstuff and to characterize the potential sources of the estrogenic
contamination.
Materials, methods, and results In the present study, we analyzed commercially available mineral water in an in vitro system with the human estrogen receptor
alpha and detected estrogenic contamination in 60% of all samples with a maximum activity equivalent to 75.2 ng/l of the natural
sex hormone 17β-estradiol. Furthermore, breeding of the molluskan model Potamopyrgus antipodarum in water bottles made of glass and plastic [polyethylene terephthalate (PET)] resulted in an increased reproductive output
of snails cultured in PET bottles. This provides first evidence that substances leaching from plastic food packaging materials
act as functional estrogens in vivo.
Discussion and conclusions Our results demonstrate a widespread contamination of mineral water with xenoestrogens that partly originates from compounds
leaching from the plastic packaging material. These substances possess potent estrogenic activity in vivo in a molluskan sentinel.
Overall, the results indicate that a broader range of foodstuff may be contaminated with endocrine disruptors when packed
in plastics. 相似文献

Background Due to the requirements of the EU Water Framework Directive and other legal regulations (e.g., national laws like the German
Federal Soil Protection Act), but also due to the implementation of the new EU chemicals management system REACH, environmental
monitoring will gain increasing importance for the surveillance of environmental quality as well as for the assessment of
chemicals. Against this background, the Work Group on ‘Environmental Monitoring’ of the Division of ‘Environmental Chemistry
and Ecotoxicology’ within the German Chemical Society has compiled a position paper on substance-related environmental monitoring.
Scope Core elements of this position paper are the definitions of important terms like monitoring, exposure monitoring, effect monitoring,
and integrated monitoring. Moreover, temporal and spatial aspects (monitoring of spatial distributions, trend monitoring,
and retrospective monitoring) and their applications are discussed. The main focus of this position paper is the coverage
of aspects which have to be observed for the preparation and implementation of a monitoring program. Essential is the clear
specification of the targets of the monitoring which determine the development of the monitoring concept and its realization,
e.g., if environmental media (compartments) or organisms are most appropriate as samples for the aim of the study. Of course,
also the properties of the target substances are important (e.g., lipophilicity/bioaccumulation as pre-requisite for an exposure
monitoring with organisms). Finally, the monitoring phases of sample planning, sampling, storage and transport of samples,
selection of analytical methods, quality assurance measures as well as reporting are discussed.
Perspectives An important issue for the future is to link the quantification of chemicals in environmental compartments (exposure and pollution
monitoring) more closely to the study of biological effects (effect monitoring) than has been the case up to now. Furthermore,
by inclusion of a spatial differentiation, a comprehensive evaluation of the state of an ecosystem can be obtained and the
relevance of the results improved. Practical examples of monitoring studies which illustrate various aspects covered in this
position paper will be presented in a series of publications by members of the Work Group in the following issues of this
journal.

Environmental legislation is developing rapidly. In addition, considerable attention is being given to the environmental impact of new technological developments. Governments as well as citizens, often through organized groups are placing unprecedented pressures on many industries and even on other parts of the government. Popular feeling has been extremely strong on such matters and resistance so far has not been strong. This is likely to change substantially and the future may see a rapid increase in the number of environmental suits especially if the continued existence of certain industries is threatened. Expert evidence will be needed to support government legislation and to support actions to preserve the environment. Such measures will have inevitable economic implications and will evoke predictable responses. Reconciling these viewpoints will provide a challenge for the community which will probably depend to a larger extent on interpretation in courts of -law. The ability of various experts to give advice through the legal process will be essential if the most effective compromises are to be found. It is the purpose of this paper to discuss the gathering and use of such scientific evidence in environmental lawsuits. 相似文献

Background, aim, and scope The Arctic holds large stores of minerals, and extracted materials are provided to the world’s economy; in this sense, the
Arctic issue associated with mining is not local but global. In a part of the Arctic region (the Kola Peninsula, 66–70° N
and 28–41° E), metal levels are generally elevated in the lake sediment. There is a question as to what results in elevated
metal levels—a natural process (naturally abundant minerals) or an anthropogenic process (mining and metallurgy). In terms
of solving this question, Staroe lake located on the Kola Peninsula was researched as a case study.
Materials and methods The following parameters were determined in relation with Staroe lake: (1) the current quality of the lake’s water—each 1,000-ml
sample was collected at a surface point and a deep point (near the bottom layer), and the collected samples were directly
analyzed after filtration; (2) atmospheric bulk deposition—bulk deposition was collected using a set of three rainwater samplers
near the lake. In addition, bulk deposition was collected in a background site (250 km to the southwest of the smelter complex)
as a reference; and (3) sediment profile (plus principal component analysis)—lake-bottom sediment was collected by an open-gravimetric
column sampler equipped with an automatic diaphragm. After collection, the sample columns were cut at a 1-cm interval for
analysis. Eigenvalues and variances by factor were calculated from the correlation coefficients.
Results The obtained data show that (1) naturally poor elements (Cu, Ni, Si, and SO4
2−) dominantly influence the lake’s water quality; (2) they are transported from the anthropogenic sources to the study lake
through the atmospheric pathway; (3) mainly the contents of Cu, Ni, Sr, and Ca have influenced the sediment quality since
the 1950s, corresponding to the industrial movement; and (4) Cu, Ni, and Sr originate from an anthropogenic source (smelter),
and Ca originates from both natural and anthropogenic sources.
Discussion As compared with the Russian standard (San Pin 2.1.980–00), the contents of NO3
− (50.3 ± 0.1 mg l−1) and particulates (2.3 ± 0.2 mg l−1) exceeded the standard levels (0.7 mg l−1 NO3
− and 45 mg l−1 particulates); Staroe lake may be slightly contaminated. However, the contamination factor (comparison with the background
data) implies that Staroe lake is considerably contaminated. There is a strong possibility that fine overburden detritus (<0.1 mm
diameter) may be transported from an open pit to the study lake by natural forces such as wind. Although it is difficult to
suppose that one factor dominantly affects the sediment quality, it follows from a factor analysis that factors 1 and 2 account
for about 70% of the total variance: Factor 1 is the most dominant, and factor 2 is the second most dominant in the variability
of sediment quality. It is considered that Cu, Sr, and Ni in factor 1 originate from anthropogenic sources because they are
poor in sediment rocks.
Conclusions The field survey conducted in Staroe lake can give the following answers to the key objectives: (1) The present water quality
is affected by Cu, Ni, Si, and SO4
2− in light of the contamination factor, and these elements originate from anthropogenic sources (the smelter and the open pit)
and are transported to the lake through the atmospheric pathway; (2) the sediment profile and statistic analysis show that
the lake quality has been influenced by deposition of metals since the 1950s; and (3) Cu, Ni, Sr, and Ca have influenced the
sediment quality in light of the most dominant factor—Cu, Ni, and Sr originate from an anthropogenic source, whereas Ca comes
from both natural and anthropogenic sources.
Recommendations and perspectives The presented lake survey shows that the dispersion of human-related pollutants via the atmospheric pathway takes place in
the Arctic region. If the current pollution continues without countermeasures, the high-latitude environment may lose its
original characteristics; hence, this subject is important when considering how to implement a wide range of environmental
protection measures in the Arctic. 相似文献

An international survey of decabromodiphenyl ethane (deBDethane) and decabromodiphenyl ether (decaBDE) in sewage sludge samples 总被引:2,自引:0,他引:2
Decabromodiphenyl ethane (deBDethane) is an additive flame retardant marketed as a replacement for decabromodiphenyl ether (decaBDE). The structures of the two chemicals are similar, and hence deBDethane may also become an environmental contaminant of concern. Environmental data on deBDethane are scarce. Since sewage sludge is an early indicator of leakage of these chemicals into the environment, an international survey of deBDethane and decaBDE levels in sludge was conducted. Samples were collected from 42 WWTPs in 12 different countries and analyzed with GC/LRMS. DeBDethane was present in sludge from all countries and may therefore be a worldwide concern. The levels of deBDethane in sludge samples from the Ruhr area of Germany were the highest so far reported in the literature (216 ng g−1 d.wt.). The [deBDethane]/[decaBDE] quotient for the whole data set ranged from 0.0018 to 0.83. High ratios were found in and around Germany where deBDethane imports are known to have been high and substitution of decaBDE with deBDethane is likely to have occurred. Low ratios were found in the USA and the UK, countries that have traditionally been large users of decaBDE. An estimate of the flux of deBDEthane from the technosphere via WWTPs to the environment within the European Union gave 1.7 ± 0.34 mg annually per person. The corresponding value for decaBDE was 41 ± 22 mg annually per person. 相似文献

The Fallacies of Concurrent Climate Policy Efforts 总被引:1,自引:0,他引:1
Marian Radetzki 《Ambio》2010,39(3):211-222
Climate policy has assumed an extreme degree of urgency in the international debate in recent years. This article begins by
taking a critical look at the scientific underpinnings of the efforts to stabilize the climate. It points to several serious
question marks on the purported relationship between greenhouse gas emissions and global warming, and expresses distrust about
claims of impending catastrophes related to rising sea levels, hurricanes, and spread of infectious disease. It then reviews
the concurrent climate policy efforts and concludes that they are incoherent, misguided and unduly costly, and that they have
so far had no perceptible impact on anthropogenic greenhouse gas emissions. The exceedingly ambitious policy plans currently
under preparation suffer from similar fallacies. For these reasons, but also because of the remaining scientific doubts and
the exorbitant costs that have to be incurred, skepticism is expressed about the preparedness to implement the climate policy
plans currently on the table. 相似文献

The zebrafish embryo model in environmental risk assessment—applications beyond acute toxicity testing 总被引:4,自引:3,他引:1
Scholz S Fischer S Gündel U Küster E Luckenbach T Voelker D 《Environmental science and pollution research international》2008,15(5):394-404
BACKGROUND, AIM, AND SCOPE: The use of fish embryos is not regulated by current legislations on animal welfare and is therefore considered as a refinement, if not replacement of animal experiments. Fish embryos represent an attractive model for environmental risk assessment of chemicals since they offer the possibility to perform small-scale, high-throughput analyses. MAIN FEATURES: Beyond their application for determining the acute toxicity, fish embryos are also excellent models for studies aimed at the understanding of toxic mechanisms and the indication of possible adverse and long-term effects. Therefore, we have reviewed the scientific literature in order to indicate alternative applications of the fish embryo model with focus on embryos of the zebrafish. RESULTS AND DISCUSSIONS: The analysis of the mode of action is important for the risk assessment of environmental chemicals and can assist in indicating adverse and long-term effects. Toxicogenomics present a promising approach to unravel the potential mechanisms. Therefore, we present examples of the use of zebrafish embryos to study the effect of chemicals on gene and protein patterns, and the potential implications of differential expression for toxicity. The possible application of other methods, such as kinase arrays or metabolomic profiling, is also highlighted. Furthermore, we show examples of toxicokinetic studies (bioconcentration, ABC transporters) and discuss limitations that might be caused by the potential barrier function of the chorion. Finally, we demonstrate that biomarkers of endocrine disruption, immune modulation, genotoxicity or chronic toxicity could be used as indicators or predictors of sub-acute and long-term effects. CONCLUSIONS: The zebrafish embryo represents a model with an impressive range of possible applications in environmental sciences. Particularly, the adaptation of molecular, system-wide approaches from biomedical research is likely to extend its use in ecotoxicology. RECOMMENDATIONS AND PERSPECTIVES: Challenges for future research are (1) the identification of further suitable molecular markers as indicators of the mode of action, (2) the establishment of strong links between (molecular) effects in short-term assays in embryos and long-term (toxic) effects on individuals, (3) the definition of limitations of the model and (4) the development of tests that can be used for regulatory purposes. 相似文献

Pesticides are synthetic chemicals used not only for improving food and feed production but also for the protection of materials and of human health and well-being. Some of these substances are suspected for adverse effects attributable to an interaction with the endocrine system of vertebrates by mimicking or inhibiting endogenous hormones. One of the biological targets important in this relation is the androgen receptor (AR). To be able to screen environmental samples for the presence of compounds which might interfere with androgen action, we aimed to develop a receptor assay based on recombinant human AR (rhAR). We herein describe an rhAR assay in which the receptor is immobilized in microtiter plates via a specific antibody. The assay can be used for high throughput screening of chemicals spread into the environment. 29 of the most recommended pesticides of the Federal Country Hessen, Germany, were tested for their ability to displace [3H]-DHT bound to the rhAR. This evaluation included the major part of the most common herbicides, insecticides and fungicides and covered three potential groups of endocrine disrupting chemicals. For 28 of the substances evaluated, the relative binding affinity to the rhAR was below 0.1% when compared to dihydrotestosterone (DHT) (100%), only fentinacetate exhibited an affinity of 1.42%. An exchange assay indicated that the binding inhibition was reversible. In consequence, fentinacetate seems to be a hormonally active substance which may be present in vegetables or fish, but also on clothing. We conclude that further investigations on this compound and its metabolites are necessary. 相似文献
