The extent of noise pollution was assessed in SIPCOT industrial area in Tamil Nadu. Five industrial sites were chosen randomly in the SIPCOT industrial complex. Noise observations were also made in selected residential areas near the SIPCOT industrial complex.

The mine-degraded lands initially lack viable mycorrhizal fungal population, and thus, the establishment of a vegetative community will be delayed. Mycorrhiza inoculation can enhance productivity of degraded land by increasing drought tolerance of plants and phosphorus availability, which are the main two limiting factors for plant establishment.

The experiment showed that noxious aquatic weeds like water hyacinth, water lettuce and cattail could be managed beneficially by converting easily in to good quality vermicompost within 2 to 3 month using Perionyx excavates earthworms. These composts recorded 0.71-1.36% total nitrogen, 0.38-0.75% total phosphorus and 0.86-1.44% total potassium, indicating its good quality as organic fertilizer.

The effects of vermicompost on the rate of growth of a variety of ornamentals, vegetables and medicinal plants have been assessed in the greenhouse and some field crops.

The present paper deals with the effect of polluted air on the chlorohyll content of mosses, namely Barbula consanguinea Jaeg., Ceratodon stenocarpus B.S.G. and Physcomitrium japonicum (Hedw.) Mitt. growing in the vicinity of National Thermal Power Corporation (NTPC) Unchahar, Rae Bareli.

The general concept behind this dissertation work is municipal solid waste management. Solid wastes and its composites affect the environment in several ways. And the major problems to be considered are the generation of leachate from solid waste dumping sites, which affects the groundwater aquifers.

The purpose of this investigation was to assess exposure to drinking water fluoride and to evaluate the risk of dental fluorosis among the Harappanahalli population. The study covered all 20 areas in Harappanahalli and 80% of population that has access to public water supplies.

The environmental implications of rainfall pattern in the recharge of groundwater system of Saharanpur regionl located in Uttar Pradesh, have been discussed. The mathematical analysis of rainfall variation of Saharanpur district for a period of 25 years (1982-2006) displays a fairly good range from 497.70 to 1566.10 mm with an annual average rainfall value of 1058.82 mm.

An integrated survey based on satellite interpretation corroborated with limited field checks was carried out with a view to assess groundwater potential of Nandimandalam-Kothapalli of Kadapa district, Andhra Pradesh falling in Survey of India toposheet no. 57J/11.

Physico-chemical and biological monitoring of groundwater samples of various wells situated near Rajaula village, Chitrakoot (Satna) Madhya Pradesh was carried out.
