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

This paper deals with studies on the removal of fluoride by using bark of drumstick and its leaves. The above said adsorbents are effective defluoridating agents and therefore used in the diet through cooked leaves and its vegetables. 2007

Studies carried out in Sal forest of Sirmaur district in Himachal Pradesh revealed that the artificially reclaimed sites develop much faster in terms of soil and vegetation as compared to abandoned mines.

This paper deals with a comparative study on the fluoride removal capacity of readily and cheaply available five kinds of materials-calcium, phosphate, magnesium and magnesium carbonate. Among these materials aluminium phosphate is the most efficient defluoridating agent. 2007

The Veli lake is the smallest among the backwaters of Kerala. The partially treated sewage and the completely untreated industrial effluents are the main sources that brought undesirable changes in the lake. For the present study three stations were fixed in the lake to test the physicochemical features (April 2000-March 2001). 2007

In Poland honey has never been included in regular pesticide residues controls. Because no maximum residues levels (MRLs) have been established for pesticides in honey it is very hard to evaluate the contamination of honey with pesticides and the possible damage to human health.

Tobacco smoking, passive smoking, and indoor air pollution from biomass fuels have been implicated as risk factors for tuberculosis (TB) infection, disease, and death. Tobacco smoking and indoor air pollution are persistent or growing exposures in regions where TB poses a major health risk.

Acid Mine Drainage (AMD) is recognized as one of the most serious environmental problem in the mining industry. The problem of acid mine drainage has been present since mining activity began thousands of years ago. Mining activity has disrupted the hydrology of mining areas so badly that it is extremely difficult to predict where water would eventually re-emerge.

Approximately 300 Asiatic lions Panthera leo persica are confined to the 1,883 km2 Gir forests in Gujarat, western India. To establish a second home for the Asiatic lion in its former range, Kuno Wildlife Division (1,280 km2, with a core 345 km2 Sanctuary) has been identified in Madhya Pradesh.

Geographic Information System (GIS) was utilized to apply a modified DRASTIC method to assess the aquifer vulnerability to pollution of English Bazar Block of Malda District, West Bengal, India. In the western, central and southern parts of the study area the aquifer is prone to contamination. Therefore, in these regions pesticides, which may contain arsenic or arsenic rich groundwater, should not be used in irrigated land or mango orchards. In order to understand the reliability of the aquifer vulnerability, sensitivity analysis was carried out.
