ABSTRACT
Limnological parameters are important criteria for determining the sustainability of water for
irrigation and drinking purpose. The Bisalpur Dam is the important centre of Rajasthan state
which is located on river Banas near by Deoli, District Tonk. The limnlogical investigation was
carried out for four complete years i.e. from September 2006 to January 2010.For physic
chemical investigation, water samples were collected from reservoir on monthly basis and the
period from 2006 to 2010 was divided into four ambiences i.e. moderate, extreme hot, extreme
cold and moist warm. The lowest mean value of PH (7.14), alkalinity (80.6), dissolved oxygen
(5.0mg/l), COD (3.1 mg/l) and TDS (90.6mg/l)were obtained from bisalpur area during moist
warm condition and the highest mean vale of pH (9.5), alkalinity (420.9 mg/l), dissolved oxygen
(7.8mg/l), COD(5.3 mg/l), total hardness (240.5mg/l) nitrate(22.8 mg/l), sulphate ions (274.5
mg/l), turbility (0.99 mg/l)and TDS(1120.5 mg/l) were obtained from Thadoli area during
extreme cold condition. On the basis of water quality parameters, it was concluded that water
pollution was present in Thadoli and Negdiya areas and these findings suggest the need for
monitoring the quality of water periodically

Ramakanta Sahoo, and Nishiprava Pattanaik
ABSTRACT
This paper examines the significant different in seasonal variations of air pollutant
concentrations in the Cuttack city from Nov 2008to Oct-2010.RSPM (Respirable Suspended
Particulate Matter), SPM (Suspended Particulate Matter), Sulphur Dioxide (SO2), Oxides of
nitrogen (NOx) and CO were collected over seven sites in Cuttack. Monthly and seasonal
variations of these pollutants have been observed and graphically compared for two
consecutive years and the annual average and range values have been calculated. It has been
observed that the concentrations of the pollutants are high in winter in comparison to the
summer and rainy seasons. It was noticed that the SPM, RSPM and CO levels at all selected sites
exceed the present prescribed limits as stipulated by Central Pollution Control Board (CPCB),
Delhi. But the SO2 and NOx levels in all the sites found under prescribed limits of CPCB. From
exceedence factor, the different pollutants are categorized into four categories. It was observed
that RSVM and CO at all locations for both the years fall under critical category. While SPM in
2008-09 fall under critical category at all locations and in 2009-10, one location fall under high
category and rest under critical categorySO2 at all locations in both the years was under low
category. NOx fall under low category in all locations expect one point in the year 2008-09 and
in 2009-10, two locations are under modern category and rest under low category.

ABSTRACT
Toxic effects of organophosphate pesticide phosphamidon, on skipper frog Euphlycits
cyanoplyctis revealed that the concentration of phosphamidon and the rate of mortality were
directly propotional to each other. The acute (120 h) impact of phosphamidon on
E.cyanophlycitis was assessed in terms of median lethal concentraction of phosphamidon (LC50)
and 12, 24, 48, 72, 96 and 12h LC50values of phosphamidon were 0.274, 0.272, 0.271,
0.269,0.268 and 0.268 ppm, respectively. The mortality occurred steadily with the passage of
time each of phosphamidon concentration thus indicating that the pesticide had not either
substantially degraded with time or the degradation products themselves were toxic. These
observations question the claims of the manufacturers of phosphamidon that the pesticide is
easily decomposable in water and it does not get absorebed by the soil or plants, thus having
very low toxicity to frog. The impact of phosphamidon was evident on the histology of
pancreas. The normal architecture
of pancreatic tissue was completely altered.
Histopathological lesions in the pancreas of treated animals were assessed in the sub lethal and
lethal (0.20 - 0.3ppm) concentration. This study clearly showed the presence of necrosis and
retention of cysts in the pancreatic cells after the administration of phosphamidon.

Used Antibiotics on Pseudomonas Aeruginosa
V. Jayalekshmy, S. Nanda Kumar, M. G. Sanal Kumar and R.S. Balamurali
ABSTRACT
The present study is an in vitro antibacterial assay on pseudomonas aeruginosa, an emerging
opportunistic pathogen, which can produce several nosocomial infections. The methanolic
extract of six indigenous medicinal plants and commercially available standard filter test discs
of nine antibiotics were studied for their antibacterial activity, using Kirby-Baeur disc diffusion
method. The results were measured as Inhibitition Zone Diameters (IZDs). In this preliminary
screening, Adathoda Vasica and Glycosmis Pentaphylla(10.5 mm each) showed maximum,
Azadirachta indica and Phillasnthus niruri (9.5 & 7 mm) showed average antibacterial activity
and minimum activity was shown by phumbago rosae and Lawsonia intermis (6.035mm).
Isolates were sensitive to all the nine antibiotics tested. Among them four have minimum
(Cloxacillin, Cephalexine, Linesolid & Lincomycin), two have medium (Gentamycin &
Cefotaxime) and three have the highest (Levoflxacin, Ampicillin/sulbactum & Tetracyciin)
activity on P.aeruginosa, without considering their concentration used. Significant variations
observed among the IZDs produced by different antibiotics (FCR- 475.88) and plant extracts
(FCR 21.98). This reveals that the selected medicinal plant extracts have significant antibacterial
activity on the tested microbes.

V.T. Valsamma and M. M. Mathew
ABSTRACT
This study reports the effects of Moringa oleifera seed extracts on purification of fresh waters.
Extracts of de-oiled seed powder of M.Oleifera PKM-1 variety in distilled water, 1% NaCl, 0.1 N
NaOH and 70% ethanol at 100, 150 and 200 mg_1 concentrations were tested for water
clarification. The results of the treatments with the extracts were studied using 18 parameters
and 100 mg_1 water extract lowered alkalinity in well and pond water and electric conductivity
from water. While 100 and 150 mg_1 water extracts effected the maximum removal of chloride
from well and pond water respectively, 200 mg_1 water extract was effective in removing
ammonia and phosphate from well water 100 mg_1 saline extract discarded maximum total
dissolved solids from well and pond water. Similarly, 100 mg_1 saline extract reduced turbidity
in well and total hardness. Calcium and magnesium hardness and nitrate in pond water and 200
mgl_1 NaCl extract effectively lowered BOD, total hardness, calcium and magnesium hardness
and nitrate and enhanced the DO level in well water and lowered COD, fluoride and ammonia
in pond water. While 150mgl_1 NaOH extract minimized phosphate concentration in pond
water, 200mg_1 NaOh extract resulted in lowering fluoride content in well water and 150mg_1
ethanol extract effectively removed COD from well water and 200mg_1 ethanol extract
successively lowered electric conductivity chloride and sulphate from well water and salinity,
BOD, total hardness, calcium and magnesium hardness, Chloride, phosphate and sulphate and
enhanced DO in pond water. The study proved that the de-oiled seed powder extracts of
M.Olefera PKM-1 variety are highly effectively in clarifying polluted well and pond water.

V.S. Bindu and S. Amina
ABSTRACT
Static bioassays were conducted in the laboratory for 96 hours to determine the median lethal
concentrations (LC50) of mercuric chloride (HgCl2) to Anabas testudineus. The LC50 of
A.testudineous for 24, 48, 72 and 96 h were 6.01, 3.2, 1.8 and 0.96 ppm, respectively. Ten
percent morality at 96 h ouccured in 0.18 ppm of HgCl2 whereas 15, 85, 90 and 95 percent
mortality were observed in 0.25, 3.69, 5.08 and 8.13 ppm, respectively. When A.testudineus
was exposed to HgCl2 for 96 h, fish exhibited a series of abnormal behavioural responses such
as erratic movements, rapid movement of operclum, secretion of excessive mucus, jumping out
of the test media, lateral swimming, loss of equilibrium etc; and finally the fish were found
dead. It is concluded that HgCl2 is highly toxic to A. testudineus.

Hit Distance and Predatory Performance of the Water Bug Diplonychus Rusticus
(Insecta: Hemiptera)
I Deepa Persis and P. Venkatesan
ABSTRACT
Most of the families in the order Hemioptera are predatory in nature. Predatory potential of
the water bug Diplonychus rusticus (both male & female bugs) exposed to varying prey
densities (10, 30, 50 & 70) of III and IV classes of mosquito larvae belonging to Culex for 1 hour,
was at the rate of (2.0, 4.4, 8.6, 9.2), (3.0, 5.6, 7.4, 10.4), (1.2, 4.2, 8.2, 9.6) and (2.0, 5.2, 5.6,
10.0) respectively. The prey death rate was maximum in male bugs. Secondly, the experiment
conducted support the concept of functional response. Prey sizes brought about changes in
predation among the sexes. The attack rate was inversely proportional to the handling time.
The handling time was -2.39, -0.31 and -1.62 for the prey densities 10, 30, 50 and 70
respectively. The attack rate (a) deprived from the equation was 0.05, 0.12 and 0.01 for
different densities. The handling time in male was (6.15, 0.29, 5.38, 4.74) and (11.49, 7.65, 6.75,
4.47) for the prey densities 10, 30, 50 & 70 respectively. The most predominant prey-predator
distance recorded throughout the experiment belonged to the minimum range comprising
mostly of 2.1cm which is approximately equal to the length of the foreleg of the bug, when the
predators (both male & female) were exposed to different prey densities 10, 30, 50 and 70 and
III and IV prey size classes of Culex larvae.

Impact of Fertigation on Leaf NPK Status and Yield of Tissue Culture Pomegranate CV.Mirdula
Grown Under Ulter High Density Planting
T. Shanmugasundaram and G. Balakrishna Murthy
ABSTRACT
A study was conducted during 2011-12 and 2012-13 to find out the effect of fertigation on leaf
NPK content and yield of tissue culture (TC) pomegranate (Punica granatum L.) ev Mirdula
grown under ultra high density planting (UHDP). The experiments was laid out in randomized
block design with five treatments of fertigation levels, namely 50, 75, 100 and 125%
recommended dose of water soluble fertilizers (applied twice in a week) including soil
application (control) and replicated four times, to test various leaf NPK content and yield
attributes of 2-3 year old TC pomegranate cv. Mirdula grown under UHDP. The investigation
indicated that 50% recommended dose of fertilizers (T2) applied through fertigation resulted in
maximum leaf N(1.67, 1.77 & 1.62%), leaf P(0.17, 0.20 & 0.14%), leaf K(1.15, 1.28 & 1.01%)
during vegetative, flowering and harvesting stages respectively The yield attributing characters
viz., number of fruits per plant (52.4), average fruit weight (211.4 g), fruit volume (228.8 cc) and
fruit yield per plant (11.1 kg) were also found to be higher in the same treatment than with soil
application of recommended doses of NPK and higher dose fertigation. Therefore (T2) 50%
recommended doses of NPK in the form of water soluble fertilizers can be suggested for
increasing the yield of two to three year old TC pomegranate cv. Mridula significantly.
