Air pollution is a serious public health problem in all over the world. Coal burning in the brick kilns is contributing significantly to the worst air quality in Uttar Pradesh. Five coal samples were collected from five different brick fields in Uttar Pradesh (Kursi Road - Lucknow, Sitapur Road - Lucknow, Diamond - Barabanki, Awadh – Barabanki and Suraj - Barabanki). Elemental composition (C, N, H and S) with CHN analyzer and trace metals (Na, K, Ca, Fe, Cr, Cd, Cu, Pb, and Ni) with atomic absorption spectrophotometer (AAS) were determined in the coal samples. Coal samples were grinded and extracted with distilled de-ionized water with temperature control water bath and sonicator. The average concentration of nitrogen, carbon, hydrogen and sulfur were 13.4 (wt%), 34.2 (wt%), 5.89 (wt%) and 4.59 (wt%), respectively. Carbon and sulfur are very important for the atmospheric pollution as they may undergo many primary and secondary chemical reactions. The average concentrations of the determined trace metals were 14.2±7.5 ppm for Sodium, 0.8±0.6 ppm for Potassium, 11.4±11.7 ppm for Calcium and 11.0 ± 12.7 ppm for Iron. Chromium, Cadmium, Cupper, Lead and Nickel concentrations were found below detection limit. The results showed that pollutants containing coals are the potential threat for human health especially for the worker those who are working in the brick industries. The management of pollutants emitted from brick kilns has to be high combustion efficiency coal particles during process of devolatisation, use of coal with particle size smaller than 3/ 4 inch and keep sufficiently long firing zone (coal feeding zone of at least 3-4 lines) so that the volatiles get sufficient space (high temperature zone) to mix and burn.
