dioxin, asbestos, toluene
, and metals such as cadmium, mercury, chromium, and lead compounds.
What are the harmful substances?
People are generally concerned about chemicals like polychlorinated biphenyls (PCBs) and dioxin which can be found at some hazardous waste sites. Products that we use daily, such as household cleaners, prescription and
over-the-counter drugs, gasoline, alcohol, pesticides, fuel oil and cosmetics
, can also be toxic.
What happens if you breathe in hazardous air?
Health problems can include
cancer, respiratory irritation, nervous system problems, and birth defects
