Identification of the maximum age group in which the agricultural labourers
suffer health hazards due to chemical Pollution using fuzzy matrix
W.B. Vasantha Kandasamy and Victor Devadoss
ABSTRACT: For the first time we use fuzzy matrix to analyze the
pollution due to chemicals and the consequent health hazards faced by the
agricultural laborers. The various health problems suffered by the
agricultural laborers throw light on the drastic effect of chemicals used as
pesticides and fertilizers. This has greeted lowered the longevity of them.

A Preliminary study on the pigment content of
melano-macrophage centres of fish from the polluted water lake, Hussainsagar,
Hyderabad, Andhra Pradesh
CHITRA, K.Y. and SREE RAM KUMAR, N.
ABSTRACT: Pigment content (lipofuscin, haemosiderin, and melanin) of
the melano-macrophage centers(MMC’s) of liver, kidney, and spleen of two
species of fish viz., Clarias batrachus and Heteropneustes fossilis, from
the polluted waters of Hussainsagar lake was demonstrated histochemically.
The number as well as the pigment content of the MMC’s was more in all the
three tissues of the fish studied when compared to the control fish from two
relatively non-polluted water bodies i.e., Himayatsagar and Osmansagar. All
the three water bodies are located in Hyderabad, Andhra Pradesh.
Key words: Water pollution, fish, melano-macrophage centers, pigment
content, tissues.

Phenomenal changes in Ground Water Quality of
Sanganer area of Jaipur District, Rajasthan (India)
Rajesh K. Gangal*, Murlidhar Tiwari** and Y. Magara***
ABSTRACT: An analysis of 25 villages ground water samples revealed
that there is a vast changes in water quality of Sanganer area of Jaipur
district. This change is due to seepage of effluents of dyeing and printing
industries of
Sanganer Tehsil of Jaipur District or other relevant causes.
The potability of ground water is going to be deteriorated. There is a
severe fluoride problem too. 75% of the villagers are suffering with dental
fluorosis, skeletal fluorosis. The fluoride concentration is varying from
1.5 ppm to 16.5 ppm. The other parameters are also having much more
concentration in comparison to W.H.O limit. Sodium percentage is very high
in most of the samples. Due to high sodium percentage the ground water is
unsuitable for irrigation purpose. The pH is also decreasing.
Key words : Ground Water pollution, seepage, fluorosis, rain effect.

ABSTRACT: To remove Rhodamine by adsorption on wollastonite pH should
be kept 2.0 for more and more adsorption.

Sanitation problems & it's solution in Durg-Bhilai
region
R.N. Khare, R.G. Gupta and A.K.Jain
ABSTRACT: Conventional wisdom dictates that water should not be
supplied without complementary sanitation. This is a development principle.
The reality, as many know, is different, because there has not been enough
funding for water supply, let alone sanitation. Given a choice, the needy
urban poor will always opt first for water supply, since it will have a
direct economic benefit, whereas sanitation will have more indirect benefits
related to health. Because sanitation in BHILAI-DURG could well be the
subject of a book by itself.
The function of this paper is
merely to give some indication of the existing status of sanitation in
Bhilai-Durg, emphasize its importance, identify some appropriate
Technologies, and look at what is needed to break out of the status quo.
Keywords : Sanitation,
Drainage, Dumping, Solid & Liquid Waste.

Bacteriological analysis of ground Water in and
around pettavaithalai, Truchirappalli, Tamilnadu (India)
A. ABDUL JAMEEL and J. SIRAJUDEEN
ABSTRACT: Ground water samples were collected during rainy and summer
seasons over a peiod of three years (2000, 2001 and 2002) in and around
Pettavaithalai area. The total viable count and bacteriological analysis
were performed during this period. The results showed the presence of
bacterial organisms in ground water and hence preventive measures have to be
taken immediately in order to avoid the bacterial contamination which
otherwise cause serious health risk.
Key words :
Bacteriological analysis, ground water, pettavaithalai.

Fuzzy C-Ellipses clustering for Oil slick spreading
detection from radarsat-1 sar and astar data
Maged Marghany
ABSTRACT: This paper introduces a new method for determining the oil
slick parcels spreading from different remotely sensed data. The concept of
new method is based on fuzzy c- ellipses clustering which implemented on
RADARSAT-1 SAR and ASTAR images. These two images acquired along two
different areas: Malacca Straits and Algerian coastal water. The study data
shows that fuzzy c-ellipses clustering capable in automatic detection of oil
slick segments. The fuzzy covariance matrix also capable to determine a new
oil slick parcel locations. It can be said that the fuzzy c-ellipses
clustering can be used as an automatic tool for monitoring the oil slick
spreading from remotely sensed data.

Radarsat-1 sar data for modelling oil slick
spreading due to ship movement impacts
Maged Marghany and Mohd. Lokman Hussien
ABSTRACT: This paper introduces a new approach for monitoring coastal
pollution due to ship navigation. Several RADARSAT-1 SAR images are used to
detect the ship effects in oil spill spreading. Fractal dimensional model is
used to detect the oil slick while the k-distribution model is used to
detect the ship. Doppler frequency shift spectrum is used to estimate the
ship velocities and their effects on spreading the oil slick on the coastal
waters. The study shows that the ship velocities play a great role in
increasing the length of the oil slick. The maximum ship velocity is 10 m/s
increased the oil slick length to 20 km.

ABSTRACT: The present investigation was initiated in January, 1985
and continued till January, 1988 to assess the effect of MIC (which leaked
from Union Carbide plant on 2/3 December, 1984) on terrestrial flora,
especially the perennial ones in and around Bhopal city. The most common
features which were encountered include chlorosis, necrosis, drying and
curling of leaves, early abscission, excessive enlargement and rupturing of
fruits. It was also found that there was total loss of leaf cover in some
plants like Ficus religiosa, Polyalthia longifolia & Cassia fistula. In
general there was decrease in ascorbic acid, Chlorophyll a total nitrogen,
and a sharp rise in the level of proline content in the plants which were
within 2 km radius of the factory, the impact gradually tapered with the
increasing distance from the source of MIC leakage and at a distance of 20
km, no such trend was noticed, as the area was far away from the source of
MIC leakage, which didn't diffuse to such a distance because of its density.
Though the investigation pertained to trees, shrubs, climbers and herbs, but
the present paper deals with 10 arboreal species which were found to be
severely affected and occurred at all the selected locations.
