The 400 years old city of Hyderabad is an industrially developed city surrounded by many industrial estates which continually discharge large amounts of wastewaters into the nearby receiving water bodies. The present paper aims to study the impact of the pollution characteristics of such industrial discharges on their receiving water bodies. 2007

The present paper deals with the observation on physico-chemical characteristics of river Saryu that was found polluted by various sources of pollution. 2007

The present study was conducted to analyse the physico-chemical characteristics of effluent discharged from the distillery unit of McDowell and Company situated in Varanadu at Cherthala Taluk, Alappuzha district in Kerala state. (2007)

The physico-chemical profile of effluent from sugar mill was determined during 2003-04. The parameters measured are temperature, colour, turbidity, pH, electrical conductivity, BOD, COD, total dissolved solids, chloride, total alkalinity, total hardness, sulphate, phosphate, total acidity, calcium and magnesium.

Quarry dust is known to alter the stomatal index of most of the plants studies. But in some plants the stomatal index remains unaffected or undergo little changes. Study carried out on selected plant species growing in the vicinity revealed foliar epidermal responses to quarry dust pollution which differed from species to species.

In India 18,289 hectares of land is under various type of land degradation due to coal mining in which 1100 ha is by overburden dump. With the increase demand of coal and its opencast mining degrade 1400 ha of fertile land every year. This deterioration in the fertility is due to loss of soil through water erosion, contamination through leaching of heavy metals and siltation with runoff.

Contamination of chromium is considered a serious environmental pollutant due to wide industrilization. The two largest sources of chromium emission in the atmosphere are from the chemical manufacturing industry and combustion of natural gas, oil and coal. 2007
