Abstract: The effect of automobile pollution on floral pigments of Caesalpinia pulcherrima Suotz. and Nerium indicum Miq. was studied. A decrease in Anthocyanin content in flowers of plants growing near Agra-Mumbai Road NH-3 was observed. There was 8 to 35% reduction noted in floral pigments. Nerium indicum flowers were found more affected than Caesalpinia pulcherrima.The reduction in pigments is attributed to auto vehicular pollution load which may adversely effect reproductive biology of plants.

Abstract: Histopathological and ultrastructural alterations induced by Cadmium toxicity after an exposure to sublethal concentrations (57mg CdCl 2 /L) for 60 days have been studied on Anabas testudineus (Bloch).The present histological study reveals the prominent changes in the stratified epithelial cells, neuroepithelial cells of taste buds of buccopharynx and SEM study depict the wrinkling and shrinkage of neighbouring epithelial cells with disruption of microridges of the epithelial cells. In the oesophagus the different histological layers become disrupted and SECs are showing marked necrosis. The SEM study reveals the increased mucous cell activity and disruption of microridges.The most conspicuous lesions were observed in stomach with degeneration of epithelium and gastric gland. The topological study recorded the alterations in the mucosal folds, destruction of columnar epithelial cells and apical plasma membranes. In the intestine the histopathological lesions are particularly observed in absorptive columnar epithelial cells showing loosened brush border and clumped nuclei. Disruptive of CECs resulting into formation of even cell sheet and mucus secretion from mucous cells are recorded through SEM study.

Abstract: Brick kiln ash is of low cost, locally available and is relatively a new adsorbent. It was investigated for its ability to remove some of the basic dyes like; Aniline Blue, Crystal Violet, Malachite Green, Methylene Blue, Rhodamine-B and Safranine from aqueous solutions. The effects of various experimental parameters; initial pH, dye concentration, sorbent dosage, ion strength, contact time were examined and optimal experimental conditions were evaluated. At initial basic pH of 10, all the six dyes studied could be removed effectively and that too in a very short period of time of just 25 minutes. The isothermal data for adsorption followed the Freundlich and Langmuir models. The adsorption results indicated that all the dyes studied in the present work can be easily removed from their aqueous solutions by using brick kiln ash as an adsorbent.

Abstract: The present study deals with statistical analysis of Physico-Chemical parameters of ground water quality in Nambiyar River Basin. The quality of ground water has been assessed by using correlation coefficient (r) between all parameters. A systematic correlation and regression study showed linear relatioship among different water quality parameters. This provides an easy and rapid method of monitoring of water quality. Highly significant (0.8<r<1.0), moderately significant (0.6<r<0.8) and significant (0.5<r<0.6) correlations between the parameters have been worked out. High correlation coefficient has been observed between TDS- Cl, Ca, SO4 , Na ; Cl - Ca; Cl - Ca; and SO4 - Ca.

Abstract: An investigation has been carried out for the evaluation of fluoride contamination in Sambher block of Jaipur district. Results were compared with standards as prescribed by ISI and WHO. Groundwater samples from various hand pumps of twelve villages of Sambher block of Jaipur district were analyzed throughout the two-years during all three sessions from May, 2003 to April, 2005 with the help of standard methods of APHA. The values of K+,Ca2+,Mg 2+,SO42- ,CO32-, TH, DO, COD and BOD are within permissible standard limits but more than 50% of the studied samples were high in pH, EC, TDS,Na+ and Cl - and RSC which suggest that these samples have water quality on critical limit. Concentrations of all heavy metals like Co, Cd, Cu, Fe, Mn, Pb and Zn were within permissible limits.

Abstract: The distribution pattern of nutrients (nitrate, phosphate and total nitrogen) and indicators (dissolved oxygen and conductivity) were measured along the river course of Muriganga and Subarnarekha and at their respective estuaries. The study investigated the extent to which mangrove forest could act as a vegetative buffer zone between disturbed fresh water and coastal water. Upriver samples of water were collected from the areas where pollution is more and it exhibited elevated concentration of nutrients. Samples were also examined from the different points of the respective estuaries to study the level of nutrients there. Expected and observed values were compated to see whether concentration of nutrients exhibited normal dilution patterns. It has been revealed and expressed through the graphs that the level of nutrients at the estuary points are lower than expected through the normal dilution. Thus mangrove forest can act as a coastal buffer of anthropogenic nutrients to the ocean environment.

Abstract: The paper deals with the determination of five heavy metals viz. Cu, Cd, Fe, Pb and Zn in surface water at different sites of upper basin of Bhoj wetland, Bhopal. The maximum average concentration of the studied metals Cu (6.75 ?g/L) was observed in Postmonsoon, Cd (3.75 ?g/L) in premonsoon, Fe (128.25 ?g/L) in Monsoon, Pb (6.75 ?g/L) in premonsoon and Zn (22.5 ?g/L) in postmonsoon during the year 2005-2006. Where as during the year 2006-2007 the maximum average concentration of Cu (7.75 ?g/L) was observed in Postmonsoon, Cd (2.75 ?g/L) in premonsoon and postmonsoon, Fe (179.25 ?g/L) in Monsoon, Pb (10.25 ?g/L) in postmonsoon and Zn (22 ?g/L) monsoon. The concentration of these metals also varied with the sampling stations. The highest average concentration of Cu (7.67 ?g/L) was observed at site-II, Cd (5.3 ?g/L) at site -IV, Fe (115.3 ?g/L) at site-II, Pb (7.67 ?g/L) at site -II and Zn (29.67 ?g/L) at site -IV during the year 2005-2006 and during the year 2006-2007 the highest average concentration of Cu (7.67 ?g/L) was observed at site-II, Cd (5.3 ?g/L) at site- IV , Fe (115.3 ?g/L) at site -II, Pb (7.67 ?g/L) at site-II and Zn (29.67 ?g/L) at the site-IV. The average concentration of Cu, Fe and Zn were within the safe limit set by various organizations (EPA, 2002b, CPCB India, 1991 and BIS , 1991) for both drinking and aqutic organisms whereas, Cd and Pb exceeded the EPA, (2002a) criterion value during the study period.
