Ecological Risk Assessment

Ecotoxicology & Ecological Risk Assessment

The Risk Science Center has an expanded suite of ecological and environmental sciences services, complementing our strong historical reputation in health risk assessment and industrial hygiene.  Our staff includes scientists with broad experience in ecotoxicology, environmental fate, and ecological risk and hazard assessment of chemical ingredients, products and by-products.  We provide our private and public sector sponsors with fully integrated health and environmental services to support safe, responsible, and compliant chemical characterization, formulation, and management.  

For more information on our Ecotoxicology or Ecological Risk Assessment Program, please contact Alison Pecquet.

Project Spotlight: Maine Lobster Pesticide Risk Assessment Support

lobsterFor the State of Maine, RSC provided support for an ongoing project to examine whether current pesticide residues have the potential to affect the lobster industry in Maine directly or via impact on other marine organisms. RSC provided support through a search of the open literature for studies that identified potential toxic impacts of selected pesticides (mainly pyrethroid). This included a review of the open literature for aquatic toxicology and bioaccumulation studies, and an evaluation of the scientific validity of these studies and their usefulness in the assessment of direct and indirect risks to aquatic invertebrates.

Project Spotlight: Risk Assessment Model for Chemicals Found in Bio-Solid Materials in Drinking Water

waterFor the Water Environment Research Foundation (WERF), the Risk Science Center identified and assembled data on health and ecological endpoints to support an Environmental Protection Agency (EPA) risk assessment model for chemicals found in bio-solid materials. Data evaluation included pharmaceuticals, personal care products, surfactants, pesticides, flame-retardants, and other contaminates of emerging concern.

Our Environmental Clients and Services

Our professional staff has led numerous projects focused on chemical use and disposal, environmental fate and transport, and ecological risk and hazard determinations at the population and community levels. Our diverse projects are conducted in support of governmental organizations, commodity and specialty chemical manufacturers, consumer product formulators, and pharmaceutical companies, among others. We serve multiple private trade associations supporting the pharmaceutical, agrochemical, and cleaning product industries and waste treatment plant owners and operators. Our unique non-profit status and scientific neutrality have allowed us to achieve an equally strong reputation across the public sector, including international, federal, state, and municipal government agencies. We often partner with other private consulting firms, governmental agencies, and non-profit NGO's on large-scale health and environmental research and regulatory programs.
