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...

Paired sediment contaminant and benthic infaunal data from prior studies following the 2010 Deepwater Horizon (DWH) oil spill in the Gulf of Mexico were analyzed using logistic regression models (LRMs) to derive sediment quality benchmarks for assessing risks of oil-related impacts to the deep-sea benthos. Sediment total polycyclic aromatic hydrocarbon (PAH) and total petroleum hydrocarbon (TPH) concentrations were used as measures of oil exposure. Taxonomic richness (average number of taxa/sample) was selected as the primary benthic response variable...

Specific environmental release categories (SPERCs) are an instrument for lower-tier environmental emissions assessments. They support chemical safety assessments under the European Union (EU) regulation Registration, Evaluation, Authorisation, and Restriction of Chemicals. SPERCs have been developed by industry and subjected to regulatory review. Within the framework of the Chemical Safety Report/Exposure Scenario Roadmap, the EU Chemicals Agency (ECHA), the EU Member State authorities, and European industry sector associations collaborate to improve the quality of the SPERCs...

Over the last 20 years, there has been increasing interest in the occurrence, fate, effects and risk of pharmaceuticals in the natural environment. However, we still have only limited or no data on ecotoxicological risks of many of the active pharmaceutical ingredients (APIs) currently in use. This is partly due to the fact that the environmental assessment of an API is an expensive, time-consuming and complicated process. Prioritisation methodologies, that aim to identify APIs of most concern in a particular situation, could therefore be invaluable in focusing experimental work on APIs that really matter...

Life cycle inventory (LCI) regionalization (i.e., the determination of input and output flows from production processes at a subcountry scale) is a priority in life cycle assessment (LCA) studies, particularly in the agri-food sector. Many regionalized LCAs fail to ensure that microlevel inventories are consistent with country-level aggregated data-or "scale consistent." They also fail to construct LCIs using international reference guidelines and trustworthy standardized data sources. This failure generates inaccuracies and biases in inventories and can compromise comparability among international LCA studies...
