“…The samples were analysed for major cations and anions as per standard methods described elsewhere (Khemani et al, 1985). The trace gases were measured by the wet scrubbing method (Khemani et al, 1980). Total Suspended Particulates were collected on Whatman 41 filter paper using a high volume air sampler with a flow rate of 1.2 m 3 /min.…”

An Acid deposition study was conducted in the vicinity of a Super Ther mal Power Plant at Singrauli, Uttar Pradesh State in India. During the mon soon season of 1992, rain water samples were collected at three sites around the power plant. Measurements of trace gases (S02, N02, NH3 and 03) and To tal Suspended Particulates (TSP) were also carried out for a period of �9.-� days during the monsoon season. Rain water samples were analysed for pH and all major inorganic ionic species. The high concentration of TSP (196 µg m-3 ) observed near the power plant may have been due to fly ash emissions from coal combustion, coal dust from the nearby coal mines and from soil dust. It was found that the rain water which was acidic in the vicinity of the power plant turned to alkaline as the distance increased from the power plant.
