A Dangerous Mix of Cancer-Causing Metals

A groundbreaking study conducted by researchers from the Indian Institute of Technology (IIT) Mandi has shed light on the severe health risks posed by dangerous levels of zinc, lead, and chromium in the groundwater of Himachal Pradesh’s Baddi-Barotiwala industrial area. The study, carried out in collaboration with IIT Jammu, has raised alarms over the high concentration of cancer-causing toxic metals in the region, calling for immediate action to mitigate these dangers.

Published in the prestigious ‘Science of the Total Environment’ journal, the research utilized advanced chemical hydrology techniques to analyze groundwater samples from the area. The results revealed alarming levels of contamination primarily stemming from industrial activities and natural geogenic sources. High concentrations of zinc, lead, cobalt, nickel, chromium, and geogenic uranium were identified, posing significant health risks to the local population.

Dr. Deepak Swami, Associate Professor at IIT Mandi, emphasized the urgent need for remediation to prevent health hazards associated with oral intake of contaminated groundwater. Collaborating with Dr. Nitin Joshi from IIT Jammu, the researchers not only identified the contamination sources but also assessed the health risks using a human health risk assessment model from the US Environmental Protection Agency (EPA).

The study emphasized the crucial role of improved effluent treatment and strict monitoring of industrial discharges to reduce health risks in the region. Geospatial maps created as part of the study serve as essential tools for policymakers and residents to understand the severity of the situation and guide future remediation efforts.

As the study underscores the critical link between industrial growth and public health, policymakers are urged to prioritize stringent environmental regulations and effective monitoring to safeguard the well-being of the local population. This research serves as a wake-up call to address the pressing issue of toxic metal contamination and prevent further health crises in the Baddi-Barotiwala region.
