Chemical Health Hazards

Chemical hazards can cause acute or chronic negative health effects from short- or long-term exposure. These chemicals are found in outdoor environments, as well as indoor environments including the home, workplace and schools. Health effects can range from skin and eye irritation to cancer and chronic diseases affecting the heart, lung, brain and other organs. We provide expertise and resources on measuring, monitoring and addressing chemical hazards.
