Abstract: The adverse health effects of the release of hazardoussubstances into the atmosphere continue being a matter of concern,especially in densely populated urban regions. Emergency responders needto have estimates of these adverse health effects in the local populationto aid planning, emergency response, and recovery efforts. For thispurpose, models that predict the transport and dispersion of hazardousmaterials are as necessary as those that estimate the adverse healtheffects in the population.In this paper, we present the results obtained by coupling aComputational Fluid Dynamics model, FLACS (FLame ACceleration Simulator),with an exposure model, DDC (Damage Differential Coupling). This coupledmodel system is applied to a scenario of hypothetical release of chlorinewith obstacles, such as buildings, and the results show how it is capableof predicting the atmospheric dispersion of hazardous chemicals, and theadverse health effects in the exposed population, to support decisionmakers both in charge of emergency planning and in charge of real-timeresponse.The results obtained show how knowing the influence of obstacles in thetrajectory of the toxic cloud and in the diffusion of the pollutantstransported, and obtaining dynamic information of the potentiallyaffected population and of associated symptoms, contribute to improve theplanning of the protection and response measures.
