Environmental Exposures

Environmental exposures occur when people, animals and the physical environment (e.g. water, land, air) come into contact with substances that may be hazardous. Hazardous substances are natural and man made toxins that have the potential to be very harmful to human health, can remain in the environment for a very long timeĀ and are suspected to contribute to a wide range of health concerns from asthma to cancer.

This site provides information about where hazardous substances come from, how to prevent or reduce their use and how to protect people and the environment from their harmful effects.

The Clandestine Drug Lab Program works to protect human health by assuring that properties formerly used in illegal drug manufacturing are properly evaluated, decontaminated, and are fit for re-occupancy.
Hazardous sites are places where there is known chemical contamination. Some examples include Superfund sites, like the Portland Harbor, abandoned mines, chemical manufacturing plants or brownfields.
Learning more about toxic substances empowers individuals to make informed decisions about their daily life. Information on this site provides an overview of the common health effects associated with exposures to a selection of toxic substances.
