  • Tipping the scales: weight of evidence approach for qualities and quantities with Susan Cormier

    Imagine you are conducting an environmental assessment, and you have several pieces of evidence for possible integration into the assessment. Are they all relevant? Are they equally valuable? Enter weight of evidence, a process to help assign value to pieces of information that might be useful for an assessment.

    Two companion articles in the November 2017 issue of IEAM present different components of a recently developed US Environmental Protection Agency weight of evidence framework: one discusses inferring qualities while the other infers quantities. Author Susan Cormier highlights the frameworks in this episode.

  • Expanding options: Alternatives analysis and predictive tox, with Tim Malloy
    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. The authors of a recent IEAM paper propose 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. In this podcast, lead author Tim Malloy presents a case for employing predictive toxicology approaches in chemical alternatives analysis and outlines ways to achieve the integration. Access the article in the September 2017 issue of IEAM.

  • Untapped resources: Finding the right ecotox studies for risk assessment, with Christina Rudén
    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 Ruden 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.

  • You are what you eat: Microplastics in seafood, with David Santillo
    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.

  • Hazard vs risk: Peter Matthiessen on assessing environmental effects of endocrine disruptors
    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.”

  • No small deal: Evaluating nanomaterials with alternatives assessment, with Rune Hjorth
    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.
