Common Chemicals Linked to Disease
Certain industrial and environmental chemicals are associated with increased disease risk. Examples include asbestos, benzene, formaldehyde, and heavy metals such as lead and cadmium. These substances appear in workplaces, older buildings, and polluted environments.
Health Effects and Exposure Routes
Exposure can occur through inhalation, ingestion, or skin contact. Short-term high exposure or long-term low exposure may cause respiratory illness, cancers, neurological disorders, and organ damage. The World Health Organization notes that chemical exposure contributes to a significant global disease burden.
Regulation and Risk Reduction
Governments and agencies set exposure limits and ban specific substances to reduce harm. The U.S. Environmental Protection Agency maintains chemical safety information and enforces standards. Workers and communities can lower risk through protective equipment, ventilation, and following safety guidelines.
