The Toxicology and Environmental Assessment Branch is composed of physicians, nurses, epidemiologists, researchers, analysts, industrial hygienists, environmental health specialists, and community outreach specialists who identify, control and prevent unwanted health effects associated with environmental hazards in highly burdened communities. For some communities, the essential elements for a healthy life are readily available; for others, the opportunities are significantly limited. The branch has several programs that work together to respond to emergent environmental and health hazards, while advocating for risk reduction and empowering communities so they can take actions to protect their health.
- Our vision is for a Los Angeles County where people are free from toxic exposures and have equal access to resources and opportunities that improve health.
- We listen to concerns about possible toxic exposures in areas of residence, schools and places of business throughout the County and responds to these concerns through education and outreach, consultation services and collaborative efforts with local, regional and state agencies.
- In addition, we partner to support local and State policies that accelerate health equity and environmental justice in our communities.
