The search for rational methods to develop criteria for various media—water, sediment, and tissue—and various receptors—aquatic, terrestrial, and human—has been a consistent and continuous enterprise from the beginning of environmental toxicology. Many of the 100 most frequently cited papers in Environmental Toxicology and Chemistry directly or indirectly address topics relevant to criteria. ...
Null hypothesis significance testing is one of the most widely used forms of statistical testing in environmental toxicology. In this short communication, the authors show that the reporting of statistical information when using null hypothesis significance testing is frequently inadequate in environmental toxicology research. The authors demonstrate this by analyzing the statistical ...
Although many experiments in environmental toxicology use standard statistical experimental designs, there are situations that arise where no such standard design is natural or applicable due to logistical constraints. For example, the layout of a lab may suggest that each shelf serve as a block with the number of experimental units per shelf either greater than or less than the number of ...
Thousands of environmental contaminants have neurotoxic properties though their ecological risk is poorly characterized. Contaminant‐associated disruptions to animal behavior and reproduction, both of which are regulated by the nervous system, provide compelling evidence of harm to decision makers but such apical endpoints are of limited predictive or harm preventative value. Neurochemical ...
The U.S. Environmental Protection Agency (EPA) published a Federal Register notice on June 28, 2019, announcing that the EPA Safer Choice Program is accepting submissions for its 2019 Safer Choice Partner of the Year Awards. The Safer Choice Program partners with businesses and others to help consumers and commercial buyers identify products with safer chemical ingredients, “without ...
The article “The ecological risk assessment of atrazine in North American surface waters” [1] is one of the few among the 100 most cited articles in Environmental Toxicology and Chemistry to specifically address risk and/or assessment of risk, and it was the first to use probabilistic approaches for a pesticide. As with all science, it was one of many steps in the refinement of procedures for ...
An emerging issue in environmental toxicology is in understanding how climate change will alter responses of organisms to chemical contaminants. The objective of this study was to characterize the interactive effects of cadmium and elevated temperature on life stage specific responses in the freshwater snail, Physa pomilia. We exposed developing eggs, juveniles and adults to cadmium (5, 15, and ...
This is the first of seven papers resulting from a Society of Environmental Toxicology and Chemistry (SETAC) international workshop titled “The Influence of Global Climate Change on the Scientific Foundations and Applications of Environmental Toxicology and Chemistry.” The workshop involved 36 scientists from 11 countries and was designed to answer the following question: How will global ...
Toxicogenomic data are expected to find significant regulatory application in three areas: - susceptibility: identifying subpopulations and life stages uniquely susceptible to environmental factors, - predictive toxicology: facilitating high-throughput chemical screening for potential adverse impacts and assisting in prioritizing chemicals believed to be most potentially toxic, ...
As natural resources become increasingly limited, the value of restoring contaminated sites, both terrestrial and aquatic, becomes increasingly apparent. Traditionally, goals for remediation have been set prior to any consideration of goals for ecological restoration. The goals for remediation have focused on removing or limiting contamination while restoration goals have targeted the ultimate ...
As part of an initiative to evaluate commercial chemicals for their effects on human and environmental health, Canada recently evaluated decamethylcyclopentasiloxane (D5; CAS no. 541‐02‐06), a high–volume production chemical used in many personal care products. The evaluation illustrated the challenges encountered in environmental risk assessments and the need for the development of better ...
The fifth Nanosafe conference was held November 7-10, 2016, in Grenoble, France. The conference included panel discussions on responsible development with non-governmental organizations; urban particles mitigation: what is reasonably possible; and nanomedicine: benefit-risk. Topics addressed during the conference included: Measurement and characterization of nano objects; Exposure; ...
Latin America is anticipated to be a major growth market for agriculture and production is increasing with use of technologies such as pesticides. Reports of contamination of aquatic ecosystems by pesticides in Latin America have raised concerns about potential for adverse ecological effects. In the registration process of pesticides, all countries require significant data packages on aquatic ...
In recent years, ecological risk assessment (ERA) has emerged as an important part of environmental protection programs. The following discussion provides a brief overview of ERA issues. What is ecological risk assessment? Ecological risk assessment is the practice of determining the nature and likelihood of effects of our actions on animals, plants, and the environment. Ecological risk ...
