An Assessment of Human Health Risk By Using Bp Risc Software

Human health risk assessment was performed to estimate the potential human health risk associated with different pollutants. The chemical of potential concern for quantitative risk assessment were selected in accordance with USEPA risk assessment guidelines. Potentially 10 km radius exposed populations were considered for the study. This HHRA considered potential future exposures for adult and child consumers [Adult and Child Residents] via ingestion, inhalation and dermal contact with different pollutants. Non- carcinogenic and carcinogenic health effects were evaluated in this HHRA. For non-carcinogenic effects, hazard quotients [HQs] were calculated by comparing the estimated average daily intakes of pollutant. For carcinogenic effects, incremental cancer risks were calculated by combining the estimated lifetime average daily intakes of different pollutants. If the Hazard Quotient is calculated to be less than 1, then no adverse health effects as per USEPA Guideline are expected as a result of exposure. If the Hazard Quotient is greater than 1, then adverse health effects are possible. The environmental and epidemiological studies conducted at Jhanor lead to the conclusion that the low levels of risk due to pollutant exposures within the area, resulting from the power plant operation and have not caused any adverse effects on human health. The health related problems found during the study like General health related complains, under nutrition, over nutrition, Anemia and Refractive error were appeared to be due to life style related factors and not due to above mentioned pollutants in emission.
