Photocatalytic degradation is a promising technology for the degradation of endosulphan and lindane.

Soil microbial biomass is the living and active part of soil organic matter, which is re-established after disturbance of the land. Study of recovery time of microbial biomass is important for the development of self-sustaining ecosystem in mine degraded land. Increase in soil microbial biomass and organic carbon contents increases the functional diversity and stability of ecosystem.

Continuous dose rate recorded by the network of environmental monitoring stations at Kalpakkam is analysed for estimating the site dose profile with respect to the local climatology. The gamma dose rate recorded comprises of the natural background as well as the dose due to the designed release of Ar-41 gaseous activity from Madras Atomic Power Station.

The main objectives of the study were to measure the indoor air quality in hospital with special emphasis on particulate matter (PM10, PM2.5 and PM1.0).

This paper deals with utilization of flyash to vegetation programmed in abandoned open cast mines of Jharia coalfields, Dhanbad, Jharkhand. Its physical properties are beneficial in vegetation purposes in abandoned opencast mines of Jharia coalfields.

The aerobic pollution load (COD and BOD) removal of spent sulphite liquor using activated porous spherical charcoal prepared from neem oil cake both as an adsorbent and fluidizing particle was studied in a fluidized-bed reactor.

The objective of this study was to investigate the removal of reactive orange 16 (RO16) dye from synthetic wastewater by the adsorption on cocoa (Theobrama cacao) shell activated carbon (CSAC).

Batch adsorption study was investigated for the removal of single and binary mixture of basic dyes (bismark brown (BB) and safranine (SF) using artocarpus heterophyllus seed carbon (AHSC) in the aqueous solution. The effect of various experimental parameters has been investigated using a batch adorption technique to obtain information on treating effluents from the dye industry.

Under the environmental impact studies of the sewerage scheme, assessment of the seasonal water quality of the sources around the oxidation ponds and few pumping stations were monitored in Trichirrappalli Sewerage Scheme, Tamil Nadu.

Contamination of aquatic resources by a variety of heavy metals is of growing concern because of health risk posed by the exposure to flora and fauna as well as human being. The vast majority of toxic metals are the waste products/by products of industrial and metallurgical processes. Other possible sources include the effluent from electroplating, storage battery manufacturing industries, tanneries, municipal sludges, extractive metallurgy processes, and metal finishing operations contains high amount of dissolved metals and the concentration reaches to a significant range.
