摘要：

Within Calcutta city of area 100 sq. km there are altogether 11516 small and big factories. And in and around Calcutta there are alone 40 factories producing only lead-ingots and lead-alloys; a few hundred thousand people live in the vicinity of these factories. Most of these factories are bereft of adequate emission treatment plant and the chimney heights also are in the range of 15-25 metres only. The analytical study of soil, water, road-dust, dust on leaves, pond-sediment of the surroundings of one such factory in Kalipark, Dum Dum is presented in this paper. The results show that the surrounding area is highly contaminated not only by lead but also from very toxic elements arsenic, cadmium and mercury.
