Green Chemistry

California Green Chemistry Workshop

Indicators of Ecotoxicity Hazards and Exposure Potential
May 10-11, 2010

David Brower Center, Richard and Rhoda Goldman Theatre
2151 Allston Way, Berkeley 94704

Green chemistry is the design of chemical products and processes that reduce or eliminate the use or generation of hazardous substances. A key component is product reformulation to replace hazardous chemicals with less hazardous ones. A major obstacle is the lack of data on exposure, environmental effects and human toxicity in determining the safety of a chemical.

A 2009 Green Chemistry law (Senate Bill 509) requires Cal/EPA’s Office of Environmental Health Hazard Assessment to evaluate and specify the hazard traits, toxicological endpoints and other relevant data to be included in California’s Toxics Information Clearinghouse. The Clearinghouse will be constructed by the Cal/EPA’s Department of Toxic Substances Control. Hazard traits for ecotoxicity and exposure potential will be included.

This workshop explores indicators of ecotoxicity and exposure potential for use when evaluating chemicals. A March 2010 workshop explored indicators of human health hazard.

Workshop sponsors: Office of Environmental Health Hazard Assessment, UCLA Law and Environmental Health Sustainable Technology Policy Program, UC’s Berkeley Center for Green Chemistry, UC Center for Occupational and Environmental Health, UC Toxic Substances Research and Teaching Program.
