The Office of Environmental Health Hazard Assessment is announcing the availability of a draft document for review by the Scientific Review Panel on Toxic Air Contaminants. This draft summarizes the carcinogenicity data and presents the derivation of a cancer inhalation unit risk factor (IUR) for isoprene, as part of the Air Toxics Hot Spots program. Cancer IURs are used to estimate lifetime cancer risks associated with inhalation exposure to a carcinogen.

This webinar is the fifth in the series, co-convened with the Ocean Protection Council. It will address the impacts of climate change on California’s oceans and coasts, and efforts underway to address them.

Explore the indicators that show how climate change is affecting California. Updates to plain language summaries of multiple indicators published in the 2022 Indicators of Climate Change in California report are now available.
