April J. Markiewicz - Associate DirectorInstitute of Environmental Toxicology
April J. Markiewicz, M.S., is the Associate Director for the Institute of Environmental Toxicology and Chemistry at Western Washington University. She received her B.S. in Fisheries and Wildlife from Michigan State University and her M.S. in Environmental Science/Aquatic Toxicology from Western Washington University. Research interests include aquatic and stream ecology with emphasis in community- and ecosystem-level interactions, ecotoxicological effects, chemical partitioning, sediment quality criteria, and microbial degradative processes. Research activities have involved conducting site-specific nutrient, metals, and pesticide analyses and performing aquatic, sediment, and wastewater effluent toxicological bioassays. Recent research projects have involved laboratory and outdoor microcosm experiments to investigate potential direct and indirect ecotoxicological effects and biodegradation rates of jet fuels released to aquatic environments. Other recent research activities have involved statistically analyzing Whole Effluent Toxicity data including TIE, effluent flow, and composition data to identify sources of toxicity. Ms Markiewicz serves as President of Western Washington University's Professional Staff Organization, is Chair of the Association of Women in Environmental Professions, as well as a member of the Society of Environmental Toxicology and Chemistry (SETAC).
