Clarifying and expanding the focus of Environmental Toxicology and Chemistry.

The Author Guidelines for Environmental Toxicology and Chemistry (ET&C) have been updated to address many issues. Please read the full version of the Guidelines online at: http://onlinelibrary.wiley.com/journal/10.1002/%28ISSN% 291552-8618/homepage/ForAuthors.html. Most noteworthy is the explicit recognition that assessing (and managing) environmental quality requires understanding the actual or potential impacts of not only chemical but also physical and biological stressors. Chemical stressors alone rarely impact ecosystems; rather, they also respond to physical and biological stressors. For example, solids, temperature, invasive species, disease, and climate change are often driving ecosystem responses and affecting the fate and effects of anthropogenic chemicals through complex interactions. Environmental Toxicology and Chemistry will publish science that furthers our understanding of cumulative stressor interactions and their ecological significance. In this regard we are adding a fourth category of papers—Nonchemical Ecological Stressors—to our existing three areas: Environmental Chemistry, Environmental Toxicology, and Hazard/ Risk Assessment. In addition, we have further clarified topic areas that are not appropriate for ET&C including: (1) papers that focus on human health toxicology, unless they are tied closely to exposures to environmental stressors or extrapolated to responses in wildlife or other aspects of ecotoxicology; (2) remediation technologies; (3) papers that focus on treatment processes dealing with effluents, wastes, and contaminants; (4) occupational exposure in humans; and (5) pollution prevention. Additional guidance has been provided regarding appropriate types of manuscripts for ET&C, including new guidance for figures and waiver of page charges for the first six printed journal pages for corresponding authors who are SETAC members in-good-standing (membership is current and has been continuous for the two years prior to submission).
