Soybeans grown in sewage sludge likely contain elevated concentrations of metals.

Elevated concentrations can be found in air, water, soil, food, sediment, sludge, and dust.

Researchers suggest that even short-term exposure at elevated concentrations could significantly contribute to heart disease.
