Cochin backwaters, a micro tidal estuary, undergo a characteristic transformation from a river dominated system during summer monsoon to a tide-dominant system during pre-monsoon season. The present study observes that as the river flow weakens after monsoon, the flushing of the estuary

'Sella' rice plant effluent is one of the major environmental pollutants. The physico-chemical characterization of effluent collected from three 'Sella' rice plants revealed that the pH of the effluent varied from 6.9-7.4 and effluent was yellow brown in colour and turbid.

China's spectacular economic growth has caused the incidence of absolute poverty to plunge over the past two decades; however, this massive rate of industrialisation has also led to a pollution crisis

In developing country like India greater attention has been focused so far only on the ground water pollution. Unlike water the study on the soil contamination has not been much attended yet. In this background, it becomes necessary to study the soil contamination in Dindigul, where the soil is mostly degraded by tannery effluents.

The present study deals with the assessment of ambient air quality with respect to respirable suspended particulate matter (RSPM or PM10 <10
m) and trace metals (Fe, Zn, Cu, Cr, Ni, Cd, Mn and Pb) concentrations in RSPM at five locations of Renukoot, an industrial area of Eastern Uttar Pradesh.

Chromium is one of the toxic and hazardous pollutants in industrial wastewaters leading to soil contamination. In this study, the feasibility study of remediating chromium contaminated soil using indigenous microorganisms and Pseudomanas fluorescens was evaluated.

Cr (VI) (Chromate) is a toxic, soluble environmental contaminant. Bacteria can reduce chromate to the insoluble and less toxic Cr (III), and thus chromate bioremediation is of interest.

A study of ground water of industrial zone of Moradabad in Uttar Pradesh has been carried out to examine quality of water for drinking purposes. The samples were collected from bore wells, tubewells, hand pumps and jet pumps. The data was analyzed for various physico-chemical parameters.
