Abstract: An attempt was made to compare a protected lake (Hadhinaru lake) with an unprotected (Shetty lake) lake by means of phytoplankton analysis. Based on phytoplankton analysis, Chlorophyceae were more abundant in Shetty lake than in Hadhinaru lake, while Cyanophyceae and Bacillariophyceae were uniformly distributed in both the lakes. Desmids were slightly higher in number in Hadhinaru lake. Euglenophyceae were more abundant in Shetty lake. Although one lake is protected from human activities and the other is left open for various activities, the findings are almost similar in both the lakes and they need regular monitoring.

Abstract: Equilibrium conditions at shores of Chennai were upset when an artificial harbour was constructed in 1875, which was projected about 1 km into the sea. Because of this construction , there is heavy accretion on the southern side of the harbour resulting in Marina beach and severe erosion on the northern side. The study of north chennai coastal area involves the collection of bathymetry of the area and data on waves, tides, currents and winds. After analysing the data,suitable remedial measures like construction of sea wall, groynes and break water were examined. Out of all , the function of sea wall was observed to be the best remedial measure in controlling the erosion. The data on physical model study available at Institute of Hydraulic and Hydrology, Poondi were examined and a suitable remedy was designed.

Abstract: Assessment of water quality in a region is important as waater is used for domestic and agricultural purposes. In most parts of south India groundwater is used extensively for domestic and agricultural purposed. The aim of this study was to assess the water quality of Kalpakkam region based on the major ions. Geologically, this study area has two distinct formations: crystalline charnockite rocks of Archean age and quaternary/recent sediments. The quaternary/recent sediments,weathered and fractured crystalline charnockite function as an unconfined aquifer system. The hydrochemical characteristics of water and its quality were studied from physico-chemical analysis of the water samples. Two characteristic facies were determined based on the results of hydrochemical analysis : (1) Na-Cl and (2) Ca-Mg-Cl facies are dominant in this region. Groundwater from the study units is generally good for drinking purposes. However,samples from some wells exceeded drinking water standards established by the BIS for EC,TDS,sodium, chloride and sulphate ions.

Abstract: There is a general perception that the phenols being toxic are not amenable to biological degradation. Continuous biodegradation of phenol in synthetic wastewater is carried out in a packed bed bioreactor using immobilized Nocardia hydrocarbonoxydans. Glass beads were used as the carrier particles for cell immobilization. The effect of influent phenol concentration on packed bed bioreactor for phenol biodegradation during start up and at steady state were studied. Almost 99.6% degradatin of 200 ppm phenol could be achieved.Percentage degradation of phenol decreased with the increase in influent concentration . The combined effect of higher phenol concentration and volumetric phenol loading might have resulted in lower degradation. Only 58.4% degradation of 1000 ppm phenol could be achieved with the packed bed bioreactor containing 6400 glass beads. Toxic effects of phenol were found to play a role at 1000 ppm influent concentration. With increase in dilution rate, the percentage degradation was decreased.

Abstract: Lead,like other heavy metals, is introduced into natural waters by industrial and domestic wastewater discharges causing environmental pollution. Conventional methods are extremely expensive or inefficient for removal of metals from wastewaters containing low concentration of dissolved metals. Biosorption is a process in which sorbents of biological sources are employed for binding heavy metals. It is a promising alternative to treat industrial effluents,mainly beacause of its low cost and high metal binding capacity. In the present work,lead (II) biosorption process by the fruiting bodies of a macrofungus (Agaricus bisporus) has been studied. The work considered the determination of lead-biomass equilibrium data in batch system. The studies were carried out in order to determine some operational parameters of lead sorption such as the effects of pH, initial metal ion concentration, biomass dosage and time required for the metal biosorbent equilibrium,contact period,etc. All the parameters showed important effect on biosorption rate and capacity.
