How can hazardous waste impact human health?

Hazardous waste can significantly impact human health primarily through potential exposure to toxic substances. When hazardous waste is improperly managed, it can release harmful chemicals into the environment. These substances can contaminate air, water, and soil, leading to exposure in the surrounding population. Individuals may come into contact with hazardous materials via inhalation, ingestion, or dermal absorption, which can lead to a variety of health issues, including respiratory problems, neurological disorders, reproductive harm, and an increased risk of cancer.

The other choices highlight positive outcomes or unrelated effects. Improving air quality is not a consequence of hazardous waste; rather, exposure to it often results in pollution and deteriorated air quality. While hazardous waste management can lead to sustainable practices, promoting sustainable agriculture is not a direct impact of hazardous waste itself. Additionally, although reducing the need for landfills is an environmental goal, it does not relate specifically to the health impacts of hazardous waste. Focus on potential exposure to toxic substances is crucial in understanding the risks posed by hazardous waste to human health.
