Estuarine response of fluoride - Investigations in Azhikode Estuary
(Kalpana Corporation, 1995)
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 ...
Particulate trace metals in Cochin backwaters: Distribution of seasonal indices
(ICAR, 1998)
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 ...
Heavy metals in fishes from coastal waters of Cochin, southwest coast of India
(NISCAIR, CSIR, 1997)
The concentration levels of copper, zinc, manganese and iron have been determined in marine fishes from Cochin area which is one of the major fishing zones along the west coast of India. The concentration of heavy metals ...
Estuarine characteristics of the lower reaches of the River Periyar (Cochin backwater)
(CSIR-NISCAIR, 1986)
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. ...
Atypical behaviour of dissolved silicate in the Cochin backwater and Periyar river
(CSIR-NISCAIR, 1984)
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 ...
Changes in water quality at Cochin harbour dredging site, south west coast of India
(NISCAIR, CSIR, 1998)
The water quality in the vicinity of the dredging did not show any appreciable change. All dissolved nutrients recorded sharp changes in the water column. After 20 minutes and 2 hours, the conditions at the dredging were ...
Hydrochemical studies along the coastal waters off Mangalore
(Environmedia, 1998)
Environmental parameters such as temperature, salinity, dissolved oxygen, BOD pH, nutrients suspended load and chlorophyll 'a' were estimated in the coastal waters of Mangalore. Four transects, each consisting of four ...
Non-conservative controls on distribution of dissolved silicate in Cochin Backwaters
(Asian Fisheries Society, Indian Branch, Mangalore (India), 1999)
Cochin backwater system was studied with regard to dissolved silicate (DSi) to understand its seasonal distribution and behaviour during estuarine mixing. Silicate had a linear relationship with salinity during the high ...
Heavy metal concentration in different tissues of fishes from coastal waters of Cochin
(Kerala: State Committee on Science, Technology and Environment, 1994)
Information on the concentration of trace metals in the environment is essential to assess the possible accumulation of these metals in the body of organisms and its transfer to man through the food chain. Muscles, alimentary ...
