The Office of Environmental Health Hazard Assessment (OEHHA) is adopting new cancer inhalation unit risk (IUR) and slope factors for 1-Bromopropane (1-BP) for use in the Air Toxics Hot Spots Program.

The Office of Environmental Health Hazard Assessment is releasing a draft document summarizing the toxicity and derivation of Reference Exposure Levels for 1-Bromopropane .  This document will be reviewed and discussed by the Scientific Review Panel on Toxic Air Contaminants (SRP) at its meeting on May 12, 2022 in Sacramento, CA.  RELs are airborne concentrations of a chemical that are not anticipated to result in adverse noncancer health effects for specified exposure durations in the general population, including sensitive subpopulations.

The Office of Environmental Health Hazard Assessment (OEHHA) is releasing a draft document for public review, summarizing the toxicity and derivation of proposed Reference Exposure Levels (RELs) for 1-Bromopropane (1-BP). The posting of the document will commence a 45-day public review period that will end on February 22, 2022.  A remote public workshop will be held virtually on January 26, 2022 at 10:00 AM using the Zoom platform.
