Concentrations of fluoride in Azhikode estuarine region (Kerala, India) were measured as a function of chlorinity during the different seasons. The type of behaviour indicated that fluoride was regulated by sea water ...

The coastal sediments (129 samples) of central- southwest coast of India, in and around Cochin, the second biggest industrial city along the west coast of India, were analyzed for their textural and geochemical fractions ...

A seasonal analysis of particulate trace metals, viz. iron, manganese, zinc, copper, cobalt and nickel collected from 4 stations in Cochin backwaters are presented. The spatial trend for cobalt, iron and nickel was stationary ...

Mean grain size distribution under different environmental conditions along the coast of Kerala showed considerable spatial variation (0.14-0.96 mm). Standard deviation values indicated a very well sorted class along all ...

Lower reaches of river Periyar were studied to assess longitudinal extent of salt water intrusion into the system during different seasons and also its effect on the flushing of pollutants introduced by the industries. ...

Dissolved silicate was determined for 1 y (1982-83) covering a wide range of salinity from the estuarine mouth to the fresh water region. Silicate concentration ranged between 0.03 and 4.75 mgl/1. Silicate-salinity ...

Temperature, salinity, pH, dissolved oxygen, inorganic phosphate, ammonia, nitrate and nitrite of seasonal and perennial prawn culture fields from 3 areas of Cochin backwaters are studied. Area 1 is a region least affected ...

The nutrient distribution of the Cochin Backwater was studied at 6 stations throughout the year The depth profiles of phosphorus (inorganic and organic), nitrogen (nitrate and nitrite) and silicon, showed a marked seasonal ...
