These pollutants include fertilizers and pesticides from agricultural runoff; sewage and food processing waste; lead, mercury, and other heavy metals; chemical wastes from industrial discharges; and chemical contamination from hazardous waste sites.

Impacts of Climate Change on Human Health in the United States: A Scientific Assessment

Climate change is affecting the health of Americans. As the climate continues to change, the risks to human health will grow, exacerbating existing health threats and creating new public health challenges. This assessment significantly advances what we know about the impacts of climate change on public health, and the confidence with which we know it. While all Americans will be affected by climate change, the report recognizes populations of concern, such as children, the elderly, outdoor workers, and those living in disadvantaged communities, who are disproportionately vulnerable.
