The study aims at the assessment of drinking water quality in terms of some metal cations in and around Rangia town at different distances from the Rangia college. The results obtained were compared with drinking water standards (WHO, 2004 and BIS).

In the present study, analysis of groundwater of BHEL industrial area of Bhopal has been done in winter, summer and monsoon season for one year (2007-08) at different sampling stations selected for this study. Two readings of sample has been observed and analysed to check the water quality index (WQI).

The biomonitoring of water quality in Bhadrakali lake Warangal, was assessed by using Odum's algal index in four sites during October 2004 to September 2005.The higest range of Odum's algal index was in between 300 to 400 with Microcystis, Nodularia, Trichodesmium, Chlamydomonas, Cladophora, Spirulina.

Increased incidences of groundwater nitrate and its impact on human health especially in infants as blue baby disease, has initiated to determine groundwater nitrate concentration in Chandrapur city of Maharashtra state. Groundwater sampling was carried out at 18 locations from dug wells and bore wells from the study area.

Studies on physico-chemical parameters of underground mine water, OCP direct discharge water and sump water of Urimari, Sayal 'D' Block, Khas Karanpura area and Bhurkunda area of South Karanpura Coalfield of Central Coalfields Limited, a subsidiary of Coal India Limited were carried out in 2004-05 and 2005-06 in all the three seasons, namely summer, monsoon and winter.

The ambient air we breathe is a mixture of nitrogen and oxygen with minor constituents, like CO2 and trace gases. Pollutants are substances which are not normally present, for example dust, smoke, industrial and automobile exhaust gaseous and particulate matter.

The vehicular emissions are one of the potential sources of air pollution in Durgapur steel city. Statistical analysis is made on the population of the city to detect its effect on human health focused only on eye and nose irritations. Two parameters, namely mode of transport and travelling time are chosen for this analysis.

The precious portland cement essentially meant for structural application is invariably used for masonry work, where as the masonry cement still remains far from common knowledge and usage. An attempt has been made in the present study to explore the possibilities of obtaining the characteristics of masonry cement from the blend of ordinary portland cement and class F flyash.

In the production of coal West-Bokaro area of Central Coalfields Limited, Ranchi plays a vital role. During the production of coal, it produces huge quantity of suspended particulate matter (SPM), respirable particulate matter (RPM/PM10) as well as gaseous pollutants. Which polluted the area badly.

The brass metal workers are affected by the flakes of brass during making of brass made utensils that causes the decrement as well as impairments of pulmonary functions. The aim of the present study is to evaluate the pulmonary function status of the workers engaged in manufacturing of brass made utensils and polishing.
