Zn, Cu and Pb levels in the aquatic phase and underlying surface sediment from three stations (viz. Shankarpur, Canning and Bali Islands) of the coastal zone of West Bengal during different seasons in 2002 were recorded. The order of the heavy metal level in the ambient media of the selected …
Concentrations of Hg, total organic carbon (TOC), Al, Fe and Mn were determined in sediment of the Amba Estuary between the mouth and the head over a distance of 24 km in December and May during 1997-2002. Temporal and spatial changes in metal concentrations appear to be due to sediment …
Calcutta, Feb. 26: The state cabinet has cleared a deep-water port to be built on reclaimed land, the first of its kind in the country, in the Hooghly river estuary. The port, with a depth of 21 metres, will allow big ships carrying crude and other cargo to offload near …
The present investigation deals with the analysis of physico-chemical characteristics, concentration of heavy metals and textural analysis of sediments in Poovar estuary of Kerala during the period 2004-2005. Three sampling stations were selected and sediments were collected for the study.
Krishna delta lost 1,783 ha between 1977 and 2000 A study published in Current Science (Vol 87, No 9) noted that the Godavari delta had lost 1,836 hectares (ha) between 1976 and 2000 (at 73.4 ha per year). The researchers said reduced river flow had caused reduction in sediment load …

Mangrove forests are extraordinarily diverse coastal communities anchored by salt-tolerant plants along certain tropical seacoasts. Their distinctive aerial roots help to trap sediment, prevent shoreline erosion, and provide habitat for a variety of sea life. Their unique mode of viviparous reproduction (producing seeds that germinate before becoming detached from the …
The histopathological studies are useful in evaluating the pollution potential of toxicants since trace levels of chemicals do not bring about animal mortality over a given period and are capable of inducing considerable damage to organ. An investigation was carried out in the vital tissue - Gill of Mugil cephalus …
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 diminishes and the nitrogen and phosphorous loadings through …
Fluoride takes part in a number of geochemical and biochemical reactions. The activity of the fluoride thus makes the ion non conservative in many occations, though the ion is included in the major ions category. Preferential enrichment of fluoride is a general observations in the coastal and estuarine environment. The …
Persistent organic pollutants found Rising sea level and erosion aside, the Sundarbans now face a new threat. An international research team has detected polybrominated diphenyl ethers (pbde), a persistent organic pollutant, in the core sediment from seven sites in the wetland. pbdes are used as flame retardants in electrical equipments, …
