As part of the Urban Waters Initiative, the Washington State Department of Ecology (Ecology) has been assessing sediment quality throughout selected urban bays that adjoin Puget Sound. Despite substantial clean-up efforts, the study found increased concentrations of certain phthalates (DEHP, BBP) at several stations, at levels exceeding the Washington State Sediment Quality Standard. A similar survey found increasing phthalate concentrations (DEHP) in Elliott Bay. Dr. Amelia Nestler from Northwest Green Chemistry will present their work on identifying functional and inherently less hazardous alternatives to five phthalates (DEHP, BBP, DBP, DEP, and DMP) currently used as plasticizers, fast fusers, and fragrance solvents/fixatives. This webinar will identify the more promising alternatives found, and solicit feedback from the audience.
