Abstract
Environments of India and of many tropical developing countries are characterized by high levels of suspended particulate matter (SPM). This is largely due to thin forest cover and prevalence of turbulence for prolonged periods resulting in resuspension of ground dust. Both these factors contribute to higher SPM with large size particles. Abundance of sunlight promotes photochemical reactions in the atmosphere and should normally increase the probability of occurrence of smog. The reasons for this are also related to the composition of the atmospheric particulates, even though in this case the leading role is played by gaseous components. Still we do not find frequent smog formation except during winters. Health hazards due to inhalation of aerosols depend not only on their total concentration in the ambient atmosphere but also on their size distribution and composition. This presentation gives a few case studies involving size distribution and composition of aerosols.
