The field of chemical regulation is experiencing a shift from risk-based approaches to preventative ones. Initiatives in the European Union (REACH) and California (Safer Consumer Products) are leading the way for such prevention-based regulation. A recent IEAM paper proposes integrating predictive toxicology into Alternatives Analysis, to expedite the process and foster a more rapid and defensible decision when identifying the most environmentally friendly chemical for a given application. Lead author Tim Malloy outlines ways to achieve the integration. Access the article in the September 2017 issue of IEAM.
It’s tempting to assume that ecotoxicologists of all professions utilize peer-reviewed studies as part of their research when conducting hazard or risk assessments under a regulatory framework. Yet that is not always the case, quite the contrary in fact. While it’s easy to incorporate the results of a study conducted under standardized methods such as good laboratory practices, the vast majority of studies do not conform to universal protocols, making it harder for regulators to vet and extract necessary data. Enter relevance assessment: an evaluation designed to help practitioners identify the most appropriate sources for the topic being addressed. Christina Rudén and colleagues offer practical guidance to evaluating relevance in their article “Assessing the relevance of ecotoxicological studies for regulatory decision making.” The article is part of the special series “Improving the Usability of Ecotoxicology in Regulatory Decision-Making.” Access the series in the July 2017 issue of IEAM.
You are what you eat, or so you think. The next time you sit down to enjoy that bowl of cioppino or salmon fillet, you may be ingesting more than you realize. Plastic pollution is widespread in global waters, and microplastics—particles smaller than 5 mm—are being increasingly found in the most popular seafood items.
From the infamous bisphenol A (BPA) to feminized male fish, endocrine-disrupting chemicals (EDS) remain at the center of many controversies involving chemicals in consumer products. International efforts to address concerns over ecotoxicological effects from EDS include both risk- and hazard-based approaches to preventing adverse effects, depending on the country or intergovernmental agency. A recent SETAC Pellston workshop convened researchers from all over the world to advise on how regulators and policy makers can make science-based decisions when evaluating EDS. Workshop organizer and lead author Peter Matthiessen joins us to discuss the synthesis paper from the workshop, “Recommended approaches to the scientific evaluation of ecotoxicological hazards and risks of endocrine-active substances.” His article leads off the special series “Ecotoxicological Hazard and Risk Assessment Approaches for Endocrine-Active Substances.” Access the full series in the March 2017 issue of IEAM.
Nanomaterials are small but key components in consumer products like electronics, sunscreens, and antimicrobial clothing, just to name a few. Despite their widespread use, scientists are still struggling to assess their potential hazards, with regulatory policy hinging on these assessments. Author Rune Hjorth discusses how alternatives assessment frameworks can be adapted to evaluate nanomaterials. Access the article, “The applicability of chemical alternatives assessment for engineered nanomaterials,” in the January 2017 issue of IEAM.
Human activities and other pressures on marine ecosystems are ever increasing, underscoring the need for responsible, sustainable management. Several types of environmental assessment exist, but which is the most appropriate for your assessment needs? Enter CUMULEO, a framework that defines common EA elements and introduces consistency, while remaining adaptable to assessments for marine and other ecosystems. We chat with Ruud Jongbloed to get the highlights of CUMULEO. Access the critical review in the October 2016 issue of IEAM.
We benefit from ecosystem services (ES) everyday—the water we drink, the food we eat, even the vacation at the beach. It is widely recognized that we need to protect the ecological processes that deliver these benefits, yet ES have not yet been formally incorporated into environmental risk assessment, one of the primary methods that inform regulatory decision making. Wayne Munns discusses the reasons for and challenges to the routine inclusion of ES endpoints in ERAs. Access the article in the July 2016 issue of IEAM.
