Giving public water authorities another tool to monitor and measure levels of human waste contamination of waters simply and rapidly would enhance public protection. Most of the methods used today detect such contamination by quantifying microbes occurring in feces in high enough...

This article provides the background for understanding the many complex variables that combine to cause pollution of the environment with the active ingredients from pharmaceuticals. It also summarizes the many approaches that could potentially reduce this pollution. Significan...

EPA has made many recent advances in high throughput bioactivity testing. However, concurrent advances in rapid, quantitative prediction of human and ecological exposures have been lacking, despite the clear importance of both measures for a risk-based approach to prioritizing an...

"Take only pictures. Leave only footprints." Perhaps the ultimate expression for the concepts of sustainability and the "ecological footprint," this credo of the hiker and spelunker reflects the collective importance of the seemingly innocuous, minuscule impacts that can accrue ...

The Clean Water Act (CWA) provides the legislative mandate for the United States Environmental Protection Agency’s Water Quality Program to restore and maintain the chemical, physical, and biological integrity of the nation’s waters. Therefore, a common goal is to maintain water...

Ultraviolet (UV)-absorbing chemicals are widely used in cosmetics, sunscreens, and plastics to block UV radiation from the sun. Parabens are preservatives and are used extensively in cosmetics, pharmaceuticals, and foods to prevent microbial growth and preserve a product’s inte...

This book chapter discusses various catalysts for environmental remediation. Detailed information on catalysis using ferrate and ferrite oxidation, TiO2 photocatalysis, and new catalysts (i.e., graphene, perovskites and graphitic carbon nitride) is provided for the degradation of...

This paper weaves a rnulti-dimensioned perspective of mass spectrometry as a career against the backdrop of mass spectrometry's key role in the past and future of environmental chemistry. Along the way, some insights are offered for better focusing the spotlight on the discipline...

A foundation for Environmental Science - Mass Spectrometry: Historically fundamental to amassing our understanding of environmental processes and chemical pollution is the realm of mass spectrometry - the mainstay of analytical chemistry - the workhorse that supplies much of the...

A solvent-free approach that involves microwave (MW) exposure of neat reactants (undiluted) catalyzed by the surfaces of recyclable mineral supports such as alumina, silica, clay, or 'doped' surfaces is presented which is applicable to a wide range of cleavage, condensation, cycl...

Slide presentation to discuss identification of pharmaceuticals for validation of ToxCast.

This presentation will discuss emerging environmental contaminants that are currently of concern to the U.S. EPA and to other agencies. Emerging contaminants include drinking water disinfection by-products (DBPs), perfluorinated chemicals, pharmaceuticals, flame retardants, benzo...

Information regarding the deposition patterns of inhaled particles has important application to the fields of toxicology and medicine. The former concerns the risk assessment of inhaled air pollutants (inhalation toxicology); the latter concerns the targeted delivery of inhaled ...

A Computational Library of the Biomolecular Targets for Toxicity: Receptors in the Endocrine System<br><br>Authors: James R. Rabinowitz and Stephen B. Little, MTB/ECD/NHEERL/ORD, and Huajun Fan, Curriculum in Toxicology, University of North Carolina<br>Structure activity models ...

The National Research Council of the United States National Academies of Science has recently released a document outlining a long-range vision and strategy for transforming toxicity testing from largely whole animal-based testing to one based on in vitro assays. “Toxicity Testin...

There is growing recognition across broad sectors of the scientific community that use of genomic biomarkers has the potential to reduce the need for conventional rodent carcinogenicity studies of industrial chemicals, agrochemicals, and pharmaceuticals through a weight-of-eviden...

Developmental toxicity is one of the most important non-cancer endpoints for both environmental and human health. Despite the fact that numerous developmental studies are being conducted, as required for regulatory decisions, there are not yet sufficient data available to develop...

There are a wide variety of existing ecotoxicity methods that may be used to address potential impacts of human pharmaceuticals on populations of aquatic organisms. Several key methods, using algae, invertebrates, or fish, focus upon measuring population-relevent effects (e.g. su...

The unprecedented explosion of the manufacture and adoption of synthetic chemicals into commerce after World War II introduced a panoply of products and materials that improved the standard of living for many people and spawned a multitrillion dollar chemical industry. From plast...

By 2030, the number of older Americans is expected to double to 70 million largely as a result of the aging of the baby boomers. The rapid growth in the number of older Americans has many public health implications, including the need to better understand the potential risks p...
