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 over 1,000 m. and a landscape aesthetics model evaluates the aesthetic value of wetlands and forests within 1,000 m from the viewer. Each of the model variables is quantified using spatially-explicit metrics on a pixel-specific basis within EcoAIM™, a GIS-based ecosystem services decision analysis support tool...

The potential performance (i.e., ability to separate non-toxic from toxic sediments) of a range of international Disposal at Sea (DaS) chemical Action Levels (ALs) was compared using a sediment chemical and toxicological database. The use of chemistry alone (without the use of further lines of evidence) did not perform well at reducing costs and protecting the environment. Although some approaches for interpreting AL1 results are very effective at filtering out the majority of acutely toxic sediments, without subsequent toxicological assessment, a large proportion of non-toxic sediments would be unnecessarily subjected to treatment and containment, and a number of sub-lethally toxic sediments would be missed...

Ecological risk assessments and risk management decisions are only as sound as the underlying information and processes to integrate it. It is important to develop transparent and reproducible procedures a priori to integrate often heterogeneous evidence. Current weight-of-evidence (WoE) approaches for effects/hazard assessment tend to conflate aspects of the assessment of the quality of the data with the strength of the body of evidence as a whole. We take forward recent developments in the critical appraisal of the reliability and relevance of individual ecotoxicological studies (this issue) as part of the Effect/Hazard assessment of prospective risk assessments and propose a streamlined WoE approach...

The primary goals of environmental monitoring are to indicate if unexpected changes related to economic 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, there are varying scientific and social challenges often resulting in their breakdown. Conceptualizing, designing, and operating monitoring programs to better delineate and align adaptive monitoring, adaptive management, and environmental risk assessment aspects with hypothesis-driven approaches, strong inference, and Adverse Outcome Pathways can overcome many of the challenges affecting existing environmental programs...

Since the publication of avian acute oral guideline OECD223, empirical data have become available to compare the performance of OECD223 with statistical simulations used to validate this guideline and with empirical data for USEPA Guideline OCSPP850.2100. Empirical studies comprised 244 for Northern bobwhite of which 73 were dose response tests and 171 were limit tests. Of the dose response tests, 26 were conducted to OECD223 (using 3-4 stages) and 33 to OCSPP850.2100 (using the single 50 bird design). Data were collected from five avian testing laboratories from studies performed between 2006 and 2013...

We propose a modified eco-efficiency (EE) framework and novel sustainability analysis methodology for green infrastructure (GI) practices used in water resource management. GI practices such as rainwater harvesting (RWH), rain gardens, porous pavements, and green roofs are emerging as viable strategies for climate change adaptation. The modified framework includes four economic, 11 environmental, and three social indicators. Using six indicators from the framework, at least one from each dimension of sustainability, we demonstrate the methodology to analyze RWH designs...

As the earth's human population continues to increase, mega-cities rapidly expand, and agriculture tries to meet their needs - ecosystems are increasingly dominated by humans. This, of course, equates to increased loadings of eroded soils, nutrients, and chemicals along with more degraded habitat. Governments will continue to struggle to address these conflicting issues and must adapt into more effective and efficient management modes. The traditional focus on using chemical-specific guidelines as the foundation of environmental protection and restoration no longer is sufficient and must move to a more realistic and effective approach...

Bioaccumulation models quantify the relationship between sediment and water exposure concentrations and resulting tissue levels of chemicals in aquatic organisms, and represent a key link in the suite of tools used to support decision making at contaminated sediment sites. Predicted concentrations in the aquatic food web provide exposure estimates for human health and ecological risk assessments, which, in turn, provide risk-based frameworks for evaluating potential remedial activities and other management alternatives based on the fish consumption pathway...

As the general public and retailers ask for disclosure of chemical ingredients in the marketplace, a number of hazard screening tools were developed to evaluate the so called "greenness" of individual chemical ingredients and/or formulations. The majority of these tools focus only on hazard, often using chemical lists, ignoring the other part of the risk equation: exposure. Using a hazard-only focus can result in regrettable substitutions, changing one chemical ingredient for another that turns out to be more hazardous or shifts the toxicity burden to others...

Wheat crops and the major wheat-growing regions of the US are not included in the six crop and region specific scenarios developed by the Environmental Protection Agency (USEPA) for exposure modeling with the Pesticide Root Zone Model conceptualized for groundwater (PRZM-GW). This work augments the current scenarios by defining appropriately vulnerable PRZM-GW scenarios for high-producing spring and winter wheat growing regions that are appropriate for use in refined pesticide exposure assessments. Initial screening-level modeling was conducted for all wheat areas across the conterminous US as defined by multiple years of the Cropland Data Layer land use dataset...

Alternatives analysis (AA) is a method used in regulation and product design to identify, assess, and evaluate the safety and viability of potential substitutes for hazardous chemicals. It requires toxicological data for the existing chemical and potential alternatives. Predictive toxicology uses in silico and in vitro approaches, computational models, and other tools to expedite toxicological data generation in more cost-effective manner than traditional approaches. This article briefly reviews the challenges associated with using predictive toxicology in regulatory AA, then presents four recommendations for its advancement...

Soil clean-up criteria define acceptable concentrations of organic chemical constituents for exposed humans. These criteria sum the estimated soil exposure over multiple pathways. Assumptions for ingestion, dermal contact, and dust exposure generally presume a chemical persists in surface soils at a constant concentration level for the entire exposure duration. For volatile chemicals this is an unrealistic assumption. A calculation method is presented for surficial soil criteria which include volatile depletion of chemical for these uptake pathways...

Access to water along a bird's migratory flyway is essential during the vital process of migration. Because of the scarcity of water in some environments, there is potential for migratory birds to encounter and drink from contaminated bodies of water. Ingestion of contaminated water may cause injury and compromise flying ability, leading to a disruption of migration. To determine injury to birds from potential exposure, it is essential to not only know the concentration of a given contaminant in the water but also the quantity and rate of water consumption by the birds...

Environmental health risk assessments often involve assessing the potential health effects of exposure to multiple chemicals at once (i.e., complex mixtures). Because the possible number of chemical combinations is very large, few controlled in vivo toxicological studies with chemical mixtures are relevant or practical. In lieu of specific mixture toxicity data, the segregated hazard index (HI) approach has been used to determine if simultaneous exposures may warrant further investigation due to their combined adverse effects...

The authorization of biocidal antifouling products for leisure boats is subject of the EU Biocides Regulation 528/2012. National specifics may be regarded by the member states in their assessment of environmental risks. The aim of this survey was to collect corresponding data and to create a data base for the environmental risk assessment of antifouling active substances in German surface waters. Water concentrations of current antifouling active substances and selected break-down products were measured in a single-sampling campaign covering 50 marinas at inland and coastal areas...
