The over- or under-prediction of risk in moderately contaminated sediments can have a large impact on the nature of applied management strategies since concentrations border on being toxic or not toxic. Project managers should give significant consideration as to how moderate levels of contaminants in native sediments and dredged material used for restoration will impact recovery of habitat. Total solid-phase (Ctotal ) and porewater (Cfree ) polycyclic aromatic hydrocarbons (PAHs) were quantified in native sediments and dredged material to determine if the predictions of risk from Ctotal are consistent with those based on Cfree ...

In 2011, the U.S. Environmental Protection Agency (USEPA) released a field-based method for estimating the extirpation of freshwater aquatic benthic invertebrates by ionic mixtures dominated by HCO3(-) , SO4(2-) , and Ca(2+) measured as specific conductivity (SC). The estimate of extirpation was SC at the 95(th) centile (XC95 ) of a weighted cumulative frequency distribution (CFD) of a genus or species over a range of SC. A CFD of XC95 values was used to predict the SC at which 5% of genera were likely to be extirpated...

Hydrodynamics and sediment transport are key physical processes contributing to habitat structure within the marine environment. Coastal development that results in the alteration of these processes (e.g., changing water flushing and/or sedimentation rates) can have detrimental impacts on sensitive systems. This is a current relevant issue in Qatar as its coastal regions continue to be developed, not only around the capital of Doha, but in many areas around this Arabian Gulf peninsula. The Northeastern Qatari coast is comprised of diverse and sensitive flora and fauna such as seagrass and macro-algae meadows, coral reefs/patches, turtles and dugongs that tolerate harsh environmental conditions...

Governments invest in 'key enabling technologies' such as nanotechnology, to solve societal challenges and boost the economy. At the same time governmental agencies demand for risk reduction to prohibit any often unknown adverse effects, and industrial parties demand for smart approaches to reduce uncertainties. Responsible research and innovation (RRI) is therefore a central theme in policy-making. Risk Analysis and Technology Assessment, together referred to as RATA, can provide a basis to assess human, environmental and societal risks of new technological developments during the various stages of technological development...

Coastal wetlands serve many important ecological services. One of these important ecological services is their use as storm buffers. Coastal wetlands provide habitat for migratory birds and aquatic species and can improve water quality. In the late 1990 s, the US Fish and Wildlife Service published a study outlining the trends of coastal wetlands from the 1950 s to early 1990 s. In this study, wetland gains and losses are calculated for Galveston County and Cameron County between 2001 and 2011. Maps from the National Land Cover Database were used to determine wetland areas for the years 2001, 2006, and 2011...

In this research work, an environmental policy procedure for setting a cap on emissions, as a crucial step in any total emission control system, has been provided and evaluated. It is shown that general regulations on emission intensities and rates do not guarantee that ambient air quality standards are met in intense industrial zones. Local emission limits are necessary to meet ambient air quality standards in these zones. To that end, we used dispersion simulators to back-calculate pollutant concentration thresholds for a large and intense energy system in the Assaluyeh region of southern Iran...

Studies on the environmental analysis of biofuels by fast pyrolysis and hydroprocessing (BFPH) have so far focused only on the environmental impacts from direct emissions and have included few indirect emissions. The influence of ignoring some indirect emissions on the environmental performance of BFPH has not been well investigated and hence is not really understood. In addition, in order to avoid shifting environmental problems from one medium to another, a comprehensive assessment of environmental impacts caused by the processes must quantify the environmental emissions to all media (air, water, and land) in relation to each life cycle stage...

The existence of large numbers of landfills that do not fulfil sanitary prerequisites presents a serious hazard for the environment in lower income countries. One of the main hazards is landfill leachate that contains various pollutants and presents a threat to groundwater. Groundwater pollution from landfills depends on various mutually interconnected factors such as the waste type and amount, the amount of precipitation, the landfill location characteristics, and operational measures, among others. Considering these factors, lower income countries face a selection problem where landfills urgently requiring remediation and closure must be identified from among a large number of sites...

Indiscriminate use of pesticides is rampant in most parts of Africa, but only scanty ecotoxicological data exist for the protection of soil organisms-and these data were usually obtained under temperate conditions, including the use of Organisation for Economic Co-operation and Development (OECD) standard test protocols. In order to assess the effects of 3 commonly used pesticides (deltamethrin, dimethoate, chlorpyrifos) on soil fauna in Africa, noncontaminated natural soils were collected from Nigeria and Tunisia...

For a long time, the environmental risk assessment (ERA) of genetically modified (GM) crops mainly focused on terrestrial ecosystems. This changed when it was scientifically established that aquatic ecosystems are exposed to GM crop residues which may negatively affect aquatic species. To assist the risk assessment process, we present a tool to identify ecologically relevant species usable in tiered testing prior to authorization or for biological monitoring in the field. The tool is derived from a selection procedure for terrestrial ecosystems with substantial but necessary changes to adequately consider the differences in the type of ecosystems...

Electronic waste (E-waste) is a growing problem across low- and middle-income countries. Agbogbloshie (Accra, Ghana) is among the world's largest and most notorious e-waste sites, with an increasing number of studies documenting a range of environmental health risks. This study aimed to provide national, regional, and international stakeholders with a summary of expert opinion on the most pressing problems arising from e-waste activities at Agbogbloshie, as well as suggested solutions to address these problems...

This paper reviews literature on aesthetics and describes the development of vista and landscape aesthetics models. Spatially explicit variables were chosen to represent physical characteristics of natural landscapes that are important to aesthetic preferences. A vista aesthetics model evaluates the aesthetics of natural landscapes viewed from distances of more than 1000 m, and a landscape aesthetics model evaluates the aesthetic value of wetlands and forests within 1000 m from the viewer. Each of the model variables is quantified using spatially explicit metrics on a pixel-specific basis within EcoAIM™, a geographic information system (GIS)-based ecosystem services (ES) decision analysis support tool...

The primary goals of environmental monitoring are to indicate whether unexpected changes related to development are occurring in the physical, chemical, and biological attributes of ecosystems and to inform meaningful management intervention. Although achieving these objectives is conceptually simple, varying scientific and social challenges often result in their breakdown. Conceptualizing, designing, and operating programs that better delineate monitoring, management, and risk assessment processes supported by hypothesis-driven approaches, strong inference, and adverse outcome pathways can overcome many of the challenges...
