Health risk associated with soil and plant contamination in industrial areas

Urban Farm DB summary

This study assessed human health risks from contact with contaminated soil and consumption of plants grown in contaminated soils in allotment gardens and farmlands located in areas affected by Zn-Pb and steel industries and hard coal mining. Using US EPA methodology and pseudo-total concentrations of Potentially Toxic Elements (PTEs) in soil and plant samples, estimated daily intake and non-carcinogenic and carcinogenic health risks were analyzed for recreational and residential exposure scenarios. Findings indicated that the proportion of different exposure pathways in total health risk decreased in the order: intake of contaminated vegetables > accidental soil ingestion > dermal contact > inhalation of contaminated soil particles, and children are more exposed to toxic effects of PTEs than seniors and economically active adults.
