Title: Sensitivity analysis of probits with respect to quantitative risk assessment of airborne toxic chemicals using IITD-QRA model

Published in: International Journal of Environment and Waste Management
Abstract: This paper deals with the modification of a validated and operational heavy gas dispersion model, namely IIT Heavy Gas (IITHG) model-1, to propose a quantitative risk assessment tool named as IITD-QRA model. IITHG model-1 is modified based on the incorporation of appropriate probit equation and other necessary parameters (e.g., equipment failure rates, weather frequency, average population density etc.) to study the sensitivity analysis of various probit relationships in QRA. The large variation in risk estimates from different probits emphasises the need for cautious interpretation of risk estimates and well tested dose response curves based on experiments. © 2010 Inderscience Enterprises Ltd. ©2010 Inderscience Enterprises Ltd.
