Earthworms studied in agricultural fields have been found to contain organic chemicals from household products and manure, indicating that such substances are entering the food chain.
Manure and biosolids, the solid byproduct of wastewater treatment, were applied to the fields as fertilizer. Earthworms continuously ingest soils for nourishment and can accumulate the chemicals present in the soil.
The chemicals investigated are considered indicators of human and animal waste sources and include a range of active ingredients in common household products such as detergents, antibacterial soaps, fragrances, and pharmaceuticals.
