Scientists and managers from government, academia, NGOs and the private sector came together in June 2014 to review the science and management related to reactive nitrogen and co-pollutants (e.g., phosphorus, sulfur) across the U.S. Department of Agriculture (USDA), U.S. Geologic...
20180826 - Systematic Empirical Evaluation of Models to Inform Risk Prioritization (ISES) (PRESENTATION)
Prioritizing the potential risk posed to human health by the thousands of chemicals that occur in commerce and the environment requires tools that can estimate exposure from limited information. High-throughput exposure (HTE) models exist to predict exposure via specific pathways...
2012 Annual Report to Characterize the Ottawa River Using Physical, Biological, and Chemical Lines of Evidence (PUBLISHED REPORT)
International concern about contaminated sediments is increasing as sustainable practices are needed to maintain water resources and waterways as important economic, commercial, recreational, and community resources. Sediments often serve as long-term sinks for legacy pollutants,...
20180212 - Using high-throughput toxicology to develop tools for regulatory decision-making and screening-level human health risk assessment (PRESENTATION)
This presentation gives an overview of how high-throughput toxicology can be used to develop tools that can have regulatory use. First, ToxCast, the toxcast data pipeline, and uncertainties are reviewed. Then, recent successes in building fit-for-purpose tools for Endocrine Disru...
Tools for Estimating Groundwater Contaminant Flux to Surface Water (PRESENTATION)
Surface water bodies adjacent to sites with contaminated groundwater may receive impacts that impair otherwise functional ecosystems and create new exposure pathways, increasing human health risks. Optimizing site characterization protocols to improve the remedy design effort is...
Additional Benefits of Federal Air-Quality Rules: Model Estimates of Controllable Biogenic Secondary Organic Aerosol (JOURNAL)
Atmospheric models that accurately describe the fate and transport of trace species for the right reasons aid in the development of effective air-quality management strategies that safeguard human health. Controllable emissions facilitate the formation of biogenic secondary organ...
Human health impact of non-potable reuse of distributed wastewater and greywater treated by membrane bioreactors (Microbial Risk Analysis) (JOURNAL)
We assessed the annual probability of infection resulting from non-potable exposures to distributed greywater and domestic wastewater treated by an aerobic membrane bioreactor (MBR) followed by chlorination. A probabilistic quantitative microbial risk assessment was conducted for...
Suspect Screening Analysis to Identify Chemical Targets in Serum for Exposure Reconstruction (PRESENTATION)
Most human biomonitoring efforts to date have been limited to bioaccumulative chemicals with known or likely human health impacts. High throughput exposure models currently rely upon these data alone for evaluation. The evolution of high resolution mass spectrometry affords the o...
