Health Effects of the Pollution We Cause. Exposure to emissions of lead, mercury, sulfur dioxide, particulate matter, carbon dioxide, and ozone-forming nitrogen dioxides are hazardous to public health. Toxic compounds, like mercury and lead, poison organ systems and can lead to brain damage and death.
Humans are not the only living creatures affected by toxic air pollutants. Some toxins, like mercury, settle onto plants and into water sources that are then consumed by animals. The health effects of these poisons are then magnified up the food chain.
