Assessment of air pollution from small scale industry.

Air pollution due to small scale industries have been found to cause serious occupational health hazards and adverse effects on vegetation and heritage. The study for air pollution impact assessment for brick kiln industries was undertaken. The stack monitoring exercise was carried out to estimate the pollution level of SPM, SO2, and NOx. The ambient air quality was also measured in the vicinity of brick kilns to assess the impact of stack emission on ground level concentration. Characterisation of SPM for toxic metals were studied. Modelling exercise was carried to predict the impact of emission of brick kiln on surrounding environment. To minimise the emission level and ground level concentration, air pollution mitigation measures are suggested.
