The Office of Environmental Health Hazard Assessment (OEHHA) is recommending that the State Water Resources Control Board (Water Board) establish the notification level (NL) for perfluorohexanoic acid (PFHxA) at 1 part per billion (equivalent to 1 microgram per liter). This recommendation is based on OEHHA’s development of a health-protective concentration intended to prevent noncancer effects, including thyroid, nasal cavity, liver, and developmental toxicity.

New Study Shows Cleaner Vehicles Lead to Healthier Air for All Californians Findings Demonstrate Importance of Equity-Driven Action

Human health impacts (heat, wildfire smoke and air quality) webinar: Bridging Science and Action.  The sixth in the series, co-convened with the California Department of Public Health and the California Air Resources Board, addresses the impacts of heat, wildfire smoke and changes in air quality on Californians’ health, and efforts underway to address them.

The California Environmental Protection Agency’s Office of Environmental Health Hazard Assessment (OEHHA) is hosting a series of webinars as part of its efforts to track and report on climate change and its impacts on California. OEHHA launched the webinar series with a symposium held on January 24, 2024.

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.
