HUMAN HEALTH RISK ASSESSMENT DUE TO HEAVY METAL CONTAMINATED SOIL IN A TANNERY WASTE DUMP SITE, KANPUR INDIA

The present study calculates the danger to human health of soil contamination from illegal dumping of basic chromium sulphate in Rania, Kanpur Dehat, Uttar Pradesh, India, caused by chromium-rich tannery waste.Iron, zinc, and chromium levels in soils were greater (12.21 mg/kg).Health risk has been assessed for children and adults aged 05-59 years through ingestion, inhalation, and Skin exposure routes.According to the findings, adults' average daily exposure (ADE) and hazardous quotient (HQ) for ingestion were Fe (5.50E-04, 1.83E-03), Zn (8.91E-03, 2.97E-02), and Cr (6.21E+00, 2.07E+03).The ADE and HQ for ingestion in children were Fe (4.86E-04, 1.62E-03), Zn (7.87E-03, 2.62E-02), and Cr (5.49E-02, 1.83E+01).The main cause of both carcinogenic and non-carcinogenic risks was chromium, whose hazardous index was almost 3.5 times higher than the acceptable level.The study concludes that there are serious health hazards, especially for children, and suggests taking corrective action immediately to mitigate these risks.
