Heavy Metal Contamination in Bore Water due to Industrial Pollution and Polluted and Non Polluted Sea Water Intrusion in Thoothukudi and Tirunelveli of South Tamil Nadu, India.
Summary of "Heavy Metal Contamination in Bore Water due to Industrial Pollution and Polluted and Non Polluted Sea Water Intrusion in Thoothukudi and Tirunelveli of South Tamil Nadu, India."
This study investigates the pollution vulnerability of bore water in the coastal region of Tirunelveli and Thoothukudi in the state of Tamilnadu, India. There are no industries in the Tirunelveli Coastal area whereas there are many industries in SIPCOT (State Industries Promotion Corporation of Tamilnadu) Thoothukudi, and coastal area of Thoothukudi. Bore water from the SIPCOT, coastal area of Thoothukudi and Tirunelveli were collected periodically from July 2006 to May 2008 for this study. These samples were tested and analyzed to find the concentrations of sodium, magnesium, aluminium, potassium, calcium, copper, cadmium, mercury and lead. The toxic cadmium concentration was found in the range of 0.00-0.22 mg Kg(-1) at SIPCOT 2 in November 2007, mercury 0.00-0.024 mg Kg(-1) and lead 0.00-0.02 mg Kg(-1) in SIPCOT 2 in January 2008. The level of contamination is higher than the WHO limits of drinking water standards; but copper and aluminium content are within the limit. On the other hand, the samples taken from bores in Tirunelveli coastal area are non-polluted, and the analysis shows that all the metals are within the limits of WHO standard.

Medical and Biotech [MESH] Definitions
The technique of washing tissue specimens with a concentrated solution of a heavy metal salt and letting it dry. The specimen will be covered with a very thin layer of the metal salt, being excluded in areas where an adsorbed macromolecule is present. The macromolecules allow electrons from the beam of an electron microscope to pass much more readily than the heavy metal; thus, a reversed or negative image of the molecule is created.
Adverse effect upon bodies of water (lakes, RIVERS, seas, groundwater etc.) caused by CHEMICAL WATER POLLUTANTS.
Gram-negative aerobic rods found in warm water (40-79 degrees C) such as hot springs, hot water tanks, and thermally polluted rivers.
The contamination of indoor air.
Platinum. A heavy, soft, whitish metal, resembling tin, atomic number 78, atomic weight 195.09, symbol Pt. (From Dorland, 28th ed) It is used in manufacturing equipment for laboratory and industrial use. It occurs as a black powder (platinum black) and as a spongy substance (spongy platinum) and may have been known in Pliny's time as "alutiae".
