Common contaminants in urban soils include pesticides, petroleum products, radon, asbestos, lead, chromated copper arsenate and creosote. Perchlorates are reactive chemicals first detected in arctic Martian soil by NASA's Phoenix lander that plopped down on Mars over five years ago in May 2008. Lead, for instance, when ingested in excessive amounts, accumulates in the soft tissues of the body (such as your internal organs) and eventually in bones and teeth. That puts you at risk if you eat them. Fine-grained clay soils or organic material in surface soils can hold contaminants tightly, which means the contaminants will accumulate if left undisturbed (that is, no excavation or tillage).

The biggest risk of ingesting soil happens when the soil is left bare. By using our site, you agree to our. This is because of faster infiltration rates of coarse-grained sandy soil types. For instance, it is generally considered safe to grow food in soil with a lead concentration of 300 ppm (75% of the EPA limit), as long as the dirt is thoroughly cleaned off everything. As a quick example, arsenic naturally occurs in some soils. The same can be said for railroad ties and other scrap lumber of unknown origins.
