The municipal solid waste (MSW) generated from different activities from various localities and a township in city areas is subject of deep concern for its proper management. The improper management of MSW is a major cause of air pollution. Present research deals with air quality parameter like SPM, RSPM, SO2 and NO2 in surrounding areas of MSW dump site Maihar district, Satna (M.P.).

Present study deals with the stack and ambient air quality monitoring of brick klins in Uttar Pradesh and air dispersion modeling was carried out using the Gaussian model to calculate the ground level concentrations (GLC) of suspended particulate matter (SPM). Based on GLC, criteria has been proposed for installation of new brick kilns and good house keeping practices have been recommended for adoption in and around the brick kilns to reduce the ill effect of pollution on the buildings, human health, flora and fauna.

This study aimed to evaluate toxic emission and combustion characteristics of rubber materials used in Indian NBC respiratory mask. A cone calorimeter was used for combustion study and FT-1R gas analyzer for emissions. Mass loss of rubber materials had indirect relationship with time to ignition.

A laboratory scale hybrid-UASB reactor was used for the treatment of sugar industry waste water fabricated from acrylic pipe of 100 mm external diameter and 90 mm internal diameter.

The capacity of sulphuric acid treated castor seed shell carbon for the removal of Hg from aqueous solution was examined.

Field observations conducted at Kanpur, to analyze the ration of biochemical oxygen demand (BOD) contributions by benthasludge to the overlaying waters of the river Ganga were presented in part 1 of this paper. This data was later correlated to the data obtained under different conditions of operating and process variables in the laboratory. Observations were made at 3 sections along the river downstream of an outfall discharging partially treated wastewater.

Thermal power plant industries produce million tonne flyash (after burning of coal) each year which consists of fine particles of unburnt raw materials and some trace elements. Generally, most common practice regarding management of this ash is making slurry of it with water and disposing in ash dyke. Although it is a temporary process, due to leaching of metals, surrounding ground water and soil may get contaminated. So, proper maintenance and regular examination of the ground water and soil quality is necessary.

India's coal demand is expected to increase with the setting up of more and more coal based power projects and to meet the demand from metallurgical and other industries. Indian coals being of drift origin contain as high as 40% ash in some cases. The coal is, therefore, required to be washed in coal washing plants so that the ash content is brought to an acceptable level, before being utilised by the industries.

The main objective of the present study was to evaluate the anaerobic digestion and composting process for disposal of municipal solid waste (MSW) on economical aspects. Economic evaluation includes 3 major costs: (i) capital cost, (ii) operation and maintenance cost and (iii) reinvestment cost.

Red sandy dunal soils of Tamil Nadu is called Theri soils. They occupy about 20,000 ha. Tuticorin district has the largest area 11,200 ha. Different interpretative systems have indicated that these are not suitable for agriculture. In this study, tank silt is used to amend the soil and the different physical parameters which make the soil better for cultivation are estimated and their interrelationships are presented.
