Fluoride concentration in rocks and soil are well documented, but data on the F concentration in coal are limited. In present paper, fluoride were monitored in rain water during rainy season at 7 location of Singrauli region in 2004.

The textile mill, run by the Assam Polyster Co-operative Society Limited (APOL) is situated at Rangia, Kamrup district of Assam and has an installed capacity of 8000 m cloth production per day from viscose, polyester and acrylic fibers. The mill releases its effluents into the agricultural land in the western side of the mill. This study has been undertaken to assess the impact of the textile mill on soil and heavy metals and of drinking water in the close vicinity of the mill.

Municipal solid waste (MSW) management is considered to be one of the major problems being faced by municipalities in the developing countries around the world and National Capital Territory of Delhi in India is not an exception. Appropriate solid waste management of a city is crucial for public health and aesthetic surroundings. The objectives of the present study are to assess the strategies adopted by the various civic agencies for management of MSW and to determine the qualitative and quantitative characteristics of the waste produced.

Air quality deterioration, especially in urban areas of developing countries, is one of the most alerting problems of modern civilization. Present investigation shows the impact of atmospheric deposition on accumulation and translocation of heavy metals in different parts of wheat plants. Results depicted that metal accumulation was higher at sites with higher pollution load than sites having less pollution.

Studies on the presence of alpha emitting nuclides in the environment assume importance since they are found to be carcinogenic. Measurement of radioactivity in arsenic contaminated drinking water has already been reported. To perform a detail study the researchers have undertaken a programme to measure radioactivity in drinking water and soil samples in three different places of North 24 Parganas in West Bengal, India, where arsenic contamination is severe.

Crude oil is of organic origin and is an extremely complex structure of hydrocarbons. Besides carbon, hydrogen, nitrogen and sulphur many other elements are present in crude oil. In oil fields, during drilling, gathering, transporting or in some other operations, some quantity of the crude oil gets spilled over the neighboring areas. The spilled crude oil affects the bio-chemical nature of the soil. As a result no vegetation occurs in those areas. Therefore, a study was made with an objective to revive the soil condition for vegetation development.

Rise in population, urbanization, tourist activity and expansion of the Kumaon region has resulted in the considerable increase of vehicular traffic. This problem particularly manifests itself around the petrol pump and bus station.

This study was undertaken to find out the biogas production potential of flower waste coming out from temples. Laboratory scale digesters of 1.5 L capacity were used and fed with flower waste without and with pretreatment.

A study has been conducted at the Naokari limestone mine located at Chandrapur district of Maharashtra state, to investigate the hydro geological condition between the mines and the surrounding areas. Water resources accounting by the demarcating different watersheds and quality of water has also been carried out to analyse major cause of ground water scarcity in the area during dry season.

This paper envisages present scenario of solid waste management system in Sabarimala Pilgrimage Centre, Kerala, during its festival season from mid November to mid January. Studies were made to delineate the possible sources, quantity and quality of solid wastes generated.
