CDC’s National Center for Environmental Health (NCEH) plans, directs, and coordinates a national program to maintain and boost the health of the American men and women by promoting a healthy atmosphere and by preventing premature death and avoidable illness and disability brought on by non-infectious, non-occupational environmental and connected elements. Environmental health is focused on the organic and constructed environments for the advantage of human health, whereas environmental protection is concerned with protecting the all-natural atmosphere for the benefit of human health and the ecosystem. TOXMAP’s chemical and environmental health facts is taken from the NLM’s Toxicology Data Network (TOXNET) 13 and PubMed , and from other authoritative sources.
