The huge amount of solid waste generation and their disposal has become a major case of concern at present. In Guwahati city about 500 metric tonnes of solid wastes are generated daily. The solid wastes collected from the various parts of the city has different heavy metal content dependeing upon the nature and type of solid wastes. Heavy metal contamination results from anthropogenic as well as natural activities and creates health hazards when entered the food chain through their application to soil.

Pot experiments was conducted to observe the impact of CdCl2, CuCl2, Pb(NO3)2 and ZnCl2 on chlorophylls of Brassica juncea, Brassica rapa, Lactuca sativa, Lepidium sativum and Daucus carota. Present studies suggest that depletion of essential micronutrients like Zn and Fe; or Zn and Cu; or Fe and Mn in the plant body after heavy metal accumulation may be one of the causes for chlorophyll loss.

The study involves the atomic absorption analysis of four selected heavy metals lead, cadmium, zinc and copper pollution in the soil samples of Pala municipality. A total of 120 surface soil samples (0-5 cm) and corresponding 120 sub-surface soil samples (5-10 cm) were collected from industrial, agricultural, road side and institutional areas.

Dhaka city produces tonnes of solid wastes everyday. Dhaka City Corporation (DCC) does not have any sanitary landfill for ultimate disposal of solid waste and for a long time it is a common practice of DCC to dipose off solid waste in open low lying areas without any segregation andf soil cover.

The trace metal levels were studied in soil and water of Tipong, Tirap and Tikak Collieries of Makum Coal Field, Tinsukia, Assam. The toxic trace metals were analyzed using Atomic Absorption Spectrophotometer (AAS). On the basis of the results obtained, it is clear that continuous mining operations have left permanent scars in the coalfield environmental scenario to a large extent.

In developing country like India greater attention has been focused so far only on the ground water pollution. Unlike water the study on the soil contamination has not been much attended yet. In this background, it becomes necessary to study the soil contamination in Dindigul, where the soil is mostly degraded by tannery effluents.
