The University of Arizona (UA), Department of Community, Environment & Policy (the Contractor) agrees to carry out the scope of work and provide the specific deliverables described below to the Office of Environmental Health Hazard Assessment (OEHHA). The proposed work is part of an OEHHA-led study designed to further our understanding of chemicals that can be released from crumb rubber under various environmental conditions, human exposures to these chemicals, and the associated chemical hazards and risks to human health. In consultation with OEHHA, the Contractor will collaborate with researchers at the Center for Environmental Research and Children’s Health (CERCH) at the University of California, Berkeley (UCB) to complete project goals.
