Environmental Health

The air we breathe; the water we drink; the complex interactions between human genetics and our surroundings. How do the built and natural environments influence our health and how can we reduce risk factors? These environmental risk factors can cause diseases such as asthma, cancer, and food poisoning. Specialists from chemistry, toxicology, engineering, and other disciplines combine their expertise to answer these important questions. Environmental health studies the impact of our surroundings on our health.

Because environmental health is so broad in scope, it is often broken down into several areas. Oneida County Health Department provides the following services in regards to your environmental health.
