The Bureau of Toxicology and Environmental Assessment is composed of physicians, nurses, epidemiologists, researchers, industrial hygienists, environmental specialists and home inspectors, who identify, control and prevent unwanted health effects associated with toxic agents in the Los Angeles County population. Our vision is for a Los Angeles County where people are safe from toxic agents and can live, work and play in a non-hazardous environment. Three programs carry out these goals: the Toxics Epidemiology Program, the Environmental Hygiene Program and the Lead and Healthy Homes Program. The Bureau listens to concerns about possible toxic exposures in areas of residence, schools and places of business throughout the county. The Bureau responds to these concerns through education and outreach, consultation services and collaborative efforts with regional and state agencies. In addition, the Bureau performs targeted investigations of potential environmental exposures that are relevant to the population of Los Angeles County.
