Purpose
The dyes and dye stuffs present in effluents released from textile dyeing industries are potentially mutagenic and carcinogenic. Phytoremediation technology can be used for remediating sites contaminated with such textile dyeing effluents. The purpose of the work was to explore the potential of Glandularia pulchella (Sweet) Tronc. to decolorize different textile dyes, textile dyeing effluent, and synthetic mixture of dyes. 相似文献272.

Introduction
This study aimed to analyze antioxidant responses and oxidative damage induced by two inorganic forms of arsenic (As; AsIII and AsV) in an estuarine polychaete species, Laeonereis acuta (Nereididae). The capacity of arsenic biotransformation was also evaluated through the methylation process considering the activity of a key enzyme involved in the metabolization process. 相似文献273.

Introduction
Ciliated protozoa play important roles in aquatic ecosystems especially regarding their functions in micro-food web and have many advantages in environmental assessment compared with most other eukaryotic organisms. The aims of this study were focused on analyzing the application of an indicator based on taxonomic relatedness of ciliated protozoan assemblages for marine environmental assessment. 相似文献274.

Purpose
Nonpoint sources (NPS) pollution has been an important cause for water quality impairment worldwide. To take the temporal variations of both NPS pollution and in-stream attenuation into consideration, an inverse modeling approach and the load duration curve (LDC) method were combined for variable nutrient total maximum daily load (TMDL) development. 相似文献275.
Spectrofluorimetric study of the ageing of mixtions used in the gildings of mediaeval wall paintings
Mounier A Belin C Daniel F 《Environmental science and pollution research international》2011,18(5):772-782
Introduction
In the Middle Ages, we could find gildings on mural paintings. Gold, silver or tin leaves were applied according to distemper or mixtion technique. For the first one, a binder as glue is necessary, and for the second, a lipidic binder is used to stick the metallic leaf. Studies of gildings materials characterization show that the mixtion technique, with a mordant, is the most common. Linseed oil seems to be the binder used. It is always mixed with a siccative agent as lead. Because of bad conditions of conservation, the gildings do not resist anymore, only remain traces of metal or the adhesive under-layer. Thanks to the binder fluorescence, we can nowadays detect ancient gildings. 相似文献276.

Background, aim and scope
Water quality impairment by heavy metal contamination is on the rise worldwide. Phytoremediation technology has been increasingly applied to remediate wastewater and stormwater polluted by heavy metals. 相似文献277.

Purpose
We tested the genetic diversity in wild mice (Mus musculus domesticus) inhabiting the asbestos-polluted area as a model for the long-term mutagenic effect of asbestos. Hazardous effects of deposited asbestos persist in the environment because of low rate of fiber disintegration. The upper layers of the soil in the vicinity of a former asbestos factory are nearly “saturated” with asbestos fibers and dust. Natural populations of mice dwell in this area and are constantly exposed to asbestos fibers. 相似文献278.

Climate adaptation is a complex task surrounded by uncertainty. To support climate adaptation policies, a new scenario approach
is pursued to explore possible discontinuous future developments of societal perspectives on climate adaptation issues. The
scenario approach was tested for a case study on Dutch river management. In a series of scenario development workshops, a
select group of stakeholders explored the perspectives on the management of the River Meuse in the past, present, and future.
The process was supported by an analytical perspectives mapping tool to illustrate and analyze the development of perspectives
over time. The process and analytical tools contributed to insight into the drivers of perspective change for the case study
at hand. Moreover, the stakeholders highlighted the potential of the approach for water management policy for creating awareness
about the plurality of perspectives and the dynamics of perspective change, monitoring perspectives and perspective change
as part of a flexible policy approach, and anticipating on the occurrence of shock events. Further work is required to better
represent the social dynamics of perspectives change, to better empirically ground the perspective change model, and to apply
integrated water models in the scenario development process to assess water–society interactions. 相似文献

Anthropogenic biomass burning in insular Southeast Asia facilitates conversion and degradation of ecosystems and emits high amounts of carbon into the atmosphere. We analyzed the influence of peat soil and land cover distribution on the occurrence and characteristics of vegetation fires. Two years of satellite-based active fire detections over Peninsular Malaysia, Sumatra, Borneo and Java were examined together with land cover and peatland maps. Our results showed that fire occurrence nearly tripled (23,000 → 68,000) from a wet La Niña year (2008) to a drier El Niño year (2009). In both years, fires were concentrated in peatlands (in 2009 41% of fires vs. 10% of land area), and the majority of large-scale burning took place in peatlands. Variation in peatland land cover within the study area was noticed to create remarkable different fire regimes. Biomass burning in the intensely managed Sumatran peatlands was characterized by large-scale land clearance fires that took place annually to varying extent. The largely unmanaged degraded peatland ecosystems of Borneo, on the other hand, experienced very little fire activity in a wet year but were ravaged by large-scale wildfires when El Niño conditions arose. We conclude that fire regime characteristics in insular Southeast Asia are strongly connected to occurrence of peat soil and land management status. This leads to high variation of fire activity within this region both annually (depending on weather patters) and over longer time range (depending on land cover/management issues) and greatly complicates estimation of the effects of fires. 相似文献

Climate is one of the more complex physical systems in nature, its behaviour being fundamentally non-linear and chaotic. In
assessing the potential risks from climate change and the costs of averting it, researchers and policymakers encounter pervasive
uncertainty. Sceptics demand to get rid of the inherent uncertainties, and some experts, on the other end, keep sending out
messages of catastrophic scenarios hoping that this will increase people’s awareness of the danger we face. The recent admission
of a mistake in IPCC’s Climate change 2007 report (promptly broadcast by all the major media groups and newspapers from Jan. 20th 2010 onwards) made by the head of
the Intergovernmental Panel on Climate Change—that Himalayan glaciers could melt away by 2035 (the IPCC claim of 2035 is wrong
by over 300 years.)—has already brought a damage to the IPCC’s reputation that is likely to be considerable. But in this paper,
perhaps risking being provocative and paradoxical, instead of looking for the right answers to what we think are inevitable uncertainties, we intend to search for new questions that may lead to a new way of
thinking and may bring about new lifestyles and behaviour for citizens and firms. 相似文献
