Air Pollution Deterministic Index Modeling: Application in Quetta, Pakistan

摘要

Mathematical model are applied to predict the sensitivity of climate to changes produced by natural phenomena and human activities. In this paper Air Pollution Deterministic Index Modeling (APDIM) for Pakistan is developed with the practical implication in Quetta City. The modeling is based on deterministic model and Pollution Indices to monitor the Ambient Air condition in Quetta City. The novelty of the model is adding a coefficient in the basic deterministic formula. The values of the coefficient balance the theoretical and experimental validations for Ambient Air. The tool gives the alerts about the weather conditions in simple indices or colour coding displays. These indices indicate the air pollution situation in the city by a single number or colour code. The application of the applied model is done in Quetta city, six criteria pollutants (CO, SO_x, NO_x, O3, TSP and PM_(10)) are chosen for modeling according to the WHO criteria which have harmful health effect on the communities. The results of the modeling indicate that the gases (CO, SOx, NOx, and O3) are touching the boundary of satisfactory to un-satisfactory zone. The cause of concern is TSP and PM_(10), which lies in the hazardous zone. APDIM is an important tool of decision making, which determine the risk assessment for communities. The aim of the tool is to inform the general public of the local area about the severity of ambient air pollution, and the possible health hazard it causes, particularly on vulnerable groups or people with existing cardiac, lungs and breathing diseases. Further the tool helps the environmentalists and policy makers to modify the policy and strategies according to the provided air data.
