Contaminants

Environmental contaminants come from many human activities, including industry, energy production, agriculture, transportation, recreation, wastewater treatment, and urban horticulture. WARC researchers conduct risk assessments of contaminants, like heavy metals, methyl mercury, copper, polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and organochlorine pesticides (such as DDT and DDE). Other contaminants of interest due to their impacts on wetland and aquatic ecosystems and species health include fragrances/musks, flame retardants, triclosan, personal-care products, and pharmaceuticals. WARC looks at the effects of these potentially damaging contaminants on wetland and aquatic plants and animals.
