Due to the surface mining at Makrana, the flora, hydrological relations and soil biological systems are drastically disturbed. In Makrana the main cause of environmental pollution is marble mining dust particulates and stone crusher dust. Analysis of the samples showed that the soil of Makrana is saline sodic because of high pH value and excess sodium presence. The agricultural field near these marble mines and stone crushers areas show poor growth and yield of crops and vegetable crops was noticed.

Concentrations of trace metals in the flesh of nine fish species commonly found in commercial
catches of a hydro-power reservoir in Sri Lanka (Victoria) were detected using the
Neutron Activation Technique. High concentrations of Al (37.8 - 208.0 μg•g-1 dry wt.) and Rb
(20.90 - 70.75 μg•g-1 dry wt.) were found in all nine species while the concentration of Zn
ranged from 20.29 to 92.00 μg•g-1 dry wt. but was found only in four species. Au was detected
in seven species but the concentration ranged from 0.004 to 0.043 μg•g-1 dry wt. The concentration

Industries without a concern for the environment deteriorate the land, water and air in an area. When the industrial activity is located in the coastal zone the harm it causes to the varied components of the environment becomes irreparable.

Effluent samples were collected from a tannery in Ambur, near North Arcot Dist, Tamil Nadu, India. The physico-chemical parameters of the effluent viz, colour, odour, pH, Electrical conductivity, TSS, TDS, BOD, COD, total hardness, calcium hardness, magnesium hardness, chloride, sulphate and total chromium were determined. The results revealed that almost all the parameters of Tannery Effluent were found to be high and exceeding the CPCB limits.

One of the industries that cause pollution of considerable magnitude in Tiruchirapalli district is tannery. Sembattu, the study area known for its location of the airport in the district is a fast developing urban site. Number of tanneries located in the area whose effluents often left untreated affect the land and water of the surrounding regions. 

A comprehensive, spatially resolved (0.25°×0.25°) fossil fuel consumption database and emissions inventory was constructed, for India, for the first time. Emissions of sulphur dioxide and aerosol chemical constituents were estimated for 1996–1997 and extrapolated to the Indian Ocean Experiment (INDOEX) study period (1998–1999). District level consumption of coal/lignite, petroleum and natural gas in power plants, industrial, transportation and domestic sectors was 9411 PJ, with major contributions from coal (54%) followed by diesel (18%).

An estimate of the global emission of mercury from anthropogenicsources in 1995 has been prepared. Major emphasis is placed onemissions from stationary combustion sources, non-ferrous metalproduction, pig iron and steel production, cement production andwaste disposal. About three quarters of the total emission,estimated to be about 1900 tonnes, was from combustion of fuels, particularly coal combustion in China, India, and South and NorthKorea. In general, the Asian countries contribute about 56% to the global emissions of mercury to the atmosphere.
