Environmental Fate & Ecotoxicology of Pesticides
Cambridge Environmental critically reviews and interprets experimental data related to the environmental fate, transport, and ecotoxicological effects of pesticides and related chemicals of concern. We present a detailed review of the study methodology. We identify deficiencies in the conduct of the research and explain the impact of these deficiencies on the study results. We conduct a range of statistical analyses on the data and summarize the results in an accessible format. We then develop independent, unbiased conclusions about the chemical's behavior and its impact on the environment.
In addition, we prepare assessments that integrate information about the physical and chemical properties of the subject chemical, as well as its use patterns, with the results of laboratory and field research studies. We identify the rate and primary routes of dissipation in terrestrial and aquatic environments, and determine the potential for surface and groundwater contamination. We identify transformation products and the conditions under which they would form, and we discuss their potential magnitude and eventual fate. Using a variety of models, we estimate the probable upper concentrations of the parent compound and any degradates of concern in surface and groundwater, soil, and foodstuffs. We calculate toxicity values such as No-Observed-Adverse-Effect-Concentrations (NOAECs) and Lethal Concentration/Effective Concentrations (LC/ECx). We estimate terrestrial and aquatic exposure to birds, mammals, insects, and fish via dietary residues.
Cambridge Environmental's Fate and Ecotoxicology Review services are directed by Dr. Kathleen Ferguson, who has more than 30 years of experience interpreting data on the environmental behavior of pesticides and other contaminants, and the ecological and human health risks they present.
