Moderately contaminated soil can be used for food production if steps are taken to reduce exposure. Contaminants in the soil have to enter the bloodstream to harm human health. There are several actions that can reduce the amount of contaminant that gets into the body and reduce the amount of contaminant that gets absorbed into the blood. Following these practices while gardening will reduce exposure and risk.
Practices can be split into two categories: Soil management and treatment, which reduces soil exposure and soil toxicity, and best practices, or healthy habits that can reduce exposure. Follow the links to learn more.
