State of the Arctic Conference 2010: International Perspectives on Progress of Research Responsive to Decision-Makers’ Information Needs

The SoA conference emphasized that urgent questions posed by society and decision-makers in response to rapid Arctic change require that Arctic research address the broader concepts of sustainability as well as adaptation to and mitigation of interrelated environmental and socioeconomic change. Murray et al. (submitted) explore progress made in this context. The SoA meeting demonstrated significant progress by the Arctic community of scientists and stakeholders in meeting this challenge, as well as the need to better engage the private sector and find more effective ways to partner with relevant research activities outside of the polar regions.     

Characterization of Naturally-occurring and Anthropogenic PAHs in Urban Sediments—Wycoff/Eagle Harbor Superfund Site

Polycyclic aromatic hydrocarbons (PAH) are ubiquitous constituents in urban sedimentary environments. The accurate characterization of their source(s) in sediments influences decisions regarding the liability for clean-up and remedial options. In this study, an extensive PAH dataset that included 50 non-alkylated (parent) and alkylated PAH groups and isomers was acquired using a modified EPA Method 8270 for the study of 5 cm intervals from 10 sediment cores (28–78 cm) obtained from the Eagle Harbor Superfund Site on Bainbridge Island, Washington. Conventional hydrocarbon “fingerprinting” and the PAH profiles in the Pb²¹⁰ age-dated cores revealed three primary PAH sources to the sediments over the past 220 years, namely (1) naturally occurring background; (2) urban runoff, and (3) creosote, the latter resulting from prior operations at the former Wyckoff wood-processing facility located on the Harbor. Naturally occurring background PAH in the pre-industrial (<1900) sediments were dominated by perylene, 1,7-dimethylphenanthrene (derived from the oxidation of abietic acid resins), and pyrogenic PAH most likely derived from historic forest fires. The concentration of PAH_total in these pre-industrial sediments was consistently less than 1 mg/kg (dry). Urban runoff in the post-industrial (>1930) sediments was dominated by low but consistent concentrations (10–20 mg/kg dry) of pyrogenic PAH derived primarily from the combustion of fossil fuel(s). The creosote-impacted sediments in the post-industrialized sediments contained high concentrations (1000–140,000 mg/kg dry) of pyrogenic PAH associated with distilled, coal-derived liquids.     

The Forum of the International HCH and Pesticides Association—a platform for international cooperation

The unsustainable life cycle management of pesticides in the last 60 years has created large pesticide stockpiles. The two major working areas of the International HCH and Pesticide Association (IHPA; www.ihpa.info) address a part of these legacies and are shortly introduced here: (1) The assessment and support of the management of the worlds single largest POPs stockpile: the globally dumped 4 to 7 million tonnes hexachlorocyclohexane (HCH) wastes from lindane production, and (2) the support for the management of the obsolete pesticides legacy in Eastern Europe, the Caucasus and Central Asia (EECCA) countries of ~240,000 t, leaving these pesticides in unregulated storages without adequate safety control being a huge risk to the environment and human health. The integrative approach IHPA takes—promoting international cooperation and the exchange of knowledge and experiences—is shortly explained. IHPA has developed various supporting tools for its work: the IHPA web page and newsletter informing on the threats and challenges, but also on the progresses of managing pesticide stockpiles; the joint GIZ-PAN-IHPA exhibition on awareness of the pesticide stockpile challenge; and the ‘International HCH and Pesticides Forum’ as most important tool to progress the integrative work and mission of IHPA. Finally, a summary of the 11th International HCH and Pesticides Forum held in Gabala, Azerbaijan is given which brought together more than 120 scientists, policy-makers, non-governmental and international organisations, industry and students from more than 40 countries to progress the obsolete pesticides and hazardous chemical waste challenge in EECCA countries. The event finished with adoption of ‘Gabala Declaration’, which aims to mobilise efforts of all stakeholders for prevention and elimination of POPs, obsolete pesticides, and hazardous chemical waste in the region.

The relationship between ambient carbon monoxide and heart rate variability—a systematic world review—2015

The objective of this report is to systematically review the literature pertaining to the evidence of the relationship between environmental carbon monoxide (CO) and heart rate variability (HRV). For this purpose, reports published in English scientific journals were critically reviewed by the authors employing PRISMA guidelines. Fifteen studies performed in China, Finland, Israel, Mexico, Taiwan, and the USA were identified as eligible to be included in the review. Out of these, 10 studies found a significant relationship between CO and HRV. However, while a proportion of these studies found an increase in parasympathetic tone, other studies found an increase in sympathetic tone. Methodological differences across these studies, including population understudy, sample size, measurement techniques, and accounting for intervening variables do not pave the way for a consensual conclusion. In conclusion, the lack of consistent results on the relationship between CO and HRV as reflected by the present review calls for more research employing appropriate indoor and outdoor ecological designs that account for possible interaction effects and individual differences. Involvement of olfactory receptors is suggested as a possible underlying mechanism for both short response latencies as well as for the diversity between individuals and samples investigated.

Introduction

The International Association for Danube Research (IAD), a legal association (Verein) according to Austrian law, presently consists of 13 member countries and 12 expert groups covering all water-relevant scientific disciplines. IAD, founded in 1956, represents a traditional and significant stakeholder in the Danube River Basin, fulfilling an important task towards an integrative water and river basin management requested by the EU Water Framework Directive.

Discussion

IAD, stretching between basic and applied research, adapted its strategy after the major political changes in 1989. IAD fosters transdisciplinary and transboundary projects to support integrative Danube River protection in line with the governmental International Commission for the Protection of the Danube River (ICPDR) in which IAD has had observer status since 1998. Recent scientific outputs of IAD encompass, amongst others, a water quality map of the Danube and major tributaries, the Sturgeon Action Plan, hydromorphological mapping of the Drava, a macrophyte inventory, and a Mures River study.

Feasibility of biochar application on a landfill final cover—a review on balancing ecology and shallow slope stability

Due to the increasing concerns on global warming, scarce land for agriculture, and contamination impacts on human health, biochar application is being considered as one of the possible measures for carbon sequestration, promoting higher crop yield and contamination remediation. Significant amount of researches focusing on these three aspects have been conducted during recent years. Biochar as a soil amendment is effective in promoting plant performance and sustainability, by enhancing nutrient bioavailability, contaminants immobilization, and microbial activities. The features of biochar in changing soil physical and biochemical properties are essential in affecting the sustainability of an ecosystem. Most studies showed positive results and considered biochar application as an effective and promising measure for above-mentioned interests. Bio-engineered man-made filled slope and landfill slope increasingly draw the attention of geologists and geotechnical engineers. With increasing number of filled slopes, sustainability, low maintenance, and stability are the major concerns. Biochar as a soil amendment changes the key factors and parameters in ecology (plant development, soil microbial community, nutrient/contaminant cycling, etc.) and slope engineering (soil weight, internal friction angle and cohesion, etc.). This paper reviews the studies on the production, physical and biochemical properties of biochar and suggests the potential areas requiring study in balancing ecology and man-made filled slope and landfill cover engineering. Biochar-amended soil should be considered as a new type of soil in terms of soil mechanics. Biochar performance depends on soil and biochar type which imposes challenges to generalize the research outcomes. Aging process and ecotoxicity studies of biochar are strongly required.     

Bioremediation trial on aged PCB-polluted soils—a bench study in Iceland

Polychlorinated biphenyls (PCBs) pose a threat to the environment due to their high adsorption capacity to soil organic matter, stability and low reactivity, low water solubility, toxicity and ability to bioaccumulate. With Icelandic soils, research on contamination issues has been very limited and no data has been reported either on PCB degradation potential or rate. The goals of this research were to assess the bioavailability of aged PCBs in the soils of the old North Atlantic Treaty Organization facility in Keflavík, Iceland and to find the best biostimulation method to decrease the pollution. The effectiveness of different biostimulation additives (N fertiliser, white clover and pine needles) at different temperatures (10 and 30 °C) and oxygen levels (aerobic and anaerobic) were tested. PCB bioavailability to soil fauna was assessed with earthworms (Eisenia foetida). PCBs were bioavailable to earthworms (bioaccumulation factor 0.89 and 0.82 for earthworms in 12.5 ppm PCB soil and in 25 ppm PCB soil, respectively), with less chlorinated congeners showing higher bioaccumulation factors than highly chlorinated congeners. Biostimulation with pine needles at 10 °C under aerobic conditions resulted in nearly 38 % degradation of total PCBs after 2 months of incubation. Detection of the aerobic PCB degrading bphA gene supports the indigenous capability of the soils to aerobically degrade PCBs. Further research on field scale biostimulation trials with pine needles in cold environments is recommended in order to optimise the method for onsite remediation.     

Dust Scrubber Design—A Critique on the State of the Art

Geographic variation in the prevalence of respiratory disease between communities has been used to incriminate air pollution at low concentrations in the production of disease. Though demographic factors and the design and conduct of survey research affect the validity of these observations, there are other complex factors which are often neglected. From several community studies planned or conducted by the authors, illustrations will be given of the effect of the following six frequently neglected factors: the reliability of the air pollution monitoring network; the validity of the air pollution monitoring network; the competing effect of differential migration of population; the competing effect of occupational pollution of members of the population; the competing effect of socioeconomic factors; and the competing effect of personal air pollution—tobacco smoking.
