fractionation studies on the sediment samples provide valuable information on the nature of the metals bound to the sediments. thirty three sediment samples of river adyar were collected during two seasons and speciation study was carried out. the industrial and domestic effluents are directed into the river course at many points in the middle and lower of the adyar river. to ascertain the exte...

The Chennai floods of 2015 were a calamity of unexpected proportions (1). The impact on the lives of the poor has been immense. Thousands needed to abandon their already precarious dwellings on the banks of the Adyar River, and other low-lying areas for temporary shelters. The differential experience and impact of disasters on different segments of the population helps understand the dynamics o...

During floods, human exposure to pathogens through contaminated water leads to the outbreak of epidemic diseases. This research presents the first extensive assessment of surface and groundwater samples collected immediately after a flood (December 2015) and post-flood (April 2016) from the Adyar River of Chennai, a major city in India, for major ions, trace metals, bacterial population, and pa...

To assess the levels of heavy metals and the extent of pollution in the surface water and sediments from the River Adyar, Chennai, the present study has been undertaken. Water and sediment samples were collected from four different stations along the course of the river in Chennai. The concentrations of heavy metals such as Zinc (Zn), Cadmium (Cd), Copper (Cu), Iron (Fe) and Lead (Pb), were det...

Remote Sensing and Geographical Information System (GIS) has become an efficient tool in delineation of drainage pattern and water resources management and its planning. Adyar watershed in the Chennai basin with an area of 686.13 Km 2 was taken up for the study. In the present study, with the aid of GIS several morphometric parameters were determined to understand the nature, landscape developm...

Microplastic particles are found in environmental compartments all over the world and receive a great deal of attention, especially aquatic environment. Currently, particularly high input microplastics via Asian rivers is assumed, but so far, there hardly any data through field measurements. Three South India were considered for this purpose to focus on their microplastic load. The emphasis was...
