New Delhi, Apr 17 (UNI) Researchers at IIT, Delhi, have developed a model to estimate toxin-related risks by any proposed new industry.

Prof. B R Gurjar and Prof. Manju Mohan of the Institute of Atmospheric Sciences were involved in this project.

"This model can assess the risk posed by emissions into the already polluted atmosphere by new pollutants from prospective industries," Prof. Mohan told UNI today.

Their aim was to develop a model for integrated risk analysis for acute and chronic exposure to toxic chemicals formed by the interaction of emissions of certain industries with chemicals already present in the atmosphere. The findings were published as a research paper in the Journal of Hazardous Materials.

"While most models study the effect of single chemicals emitted in the air or water, without considering other pollutants already present, the integrated risk posed by interaction of newly-added pollutants with already existing ones is hardly taken into consideration in calculations," Prof. Mohan added.

In the paper, individual, geological and societal risk factors have been estimated for two hypothetical Indian industries that may cause acute risk due to accidental release of chlorine into the atmosphere.
