Abstract: In the present investigation, a feasibility study is made to use Rice Husk Ash as an admixture to an already replaced Cement with fly ash (Portland Pozzolana Cement) in Concrete, and an attempt has been made to investigate the strength parameters of concrete (Compressive and Flexural). For control concrete, IS method of mix design is adopted and considering this a basis, mix design for replacement method has been made. Five different replacement levels namely 5%, 7.5%, 10%, 12.5% and 15% are chosen for the study concern to replacement method. A range of curing periods starting from 3 days, 7 days, 28 days and 56 days are considered in the present study. A replacement of 7.5% RHA concrete shows better strength properties comparitively.

Keywords: Amaravathy river basin, Ground water, physico-chemical characteristics
Abstract: Amarvathy river is a tributary of river Cauvery in Tamilnadu. This is the main water source for domestic, agriculture and industrial activities in the river basin. Karur is an industrial town located on the bank of river Amaravathy. There are 486 textile processing units in operation and discharge about 14450 KLD of partially treated effluent into river. Karur town sewage about 5000 KLD is treated and discharged into river. The ground water quality in the downstream is deteriorated due to continuous discharge of effluent. In order to assess the present quality of ground water, 13 open wells were identified in the river basin and samples were collected during pre-monsoon and post-monsoon and analyzed for physico-chemical parameters. TDS, total alkalinity, total hardness, calcium, chlorides and sulphates were exceeded the desirable limit. River water samples were collected at the upstream and downstream of Karur and the result reveals that the river meets Class C inland surface water standards. However during summer season, there is no flow in river and the rivre acts as drainage for the effluent. Hence there is severe impact on the groundwater quality in the downstream. The best option to protect the ground water quality in the river basin is that the textile processing units shall adopt zero liquid discharge system and completely recycle the treated effluent.

Abstract: The sample of industrial effluent was collected from the industrial effluent discharge site to river Periyar. The test species, a blue green alga Spirulina platensis was inoculated at different concentrations of effluent such as 10%, 20% and 50%. After 10 days treatment the effluent samples were anlaysed for selected physiochemical characters. The growth of Spirulina platensis was measured at every two days interval for ten days. At 20% effluent concentration the maximum biomass and BOD and fluoride removal were obtained.

Abstract: The cytological effects of mercury chloride on the root tip cells of Allium cepa L were studied. Onions were treated with 25, 50, 75 & 100 ppm of mercury chloride solution for 96 hours, after which both macroscopic (root length) and microscopic (Mitotic Index, Somatic chromosomal anomalies) parameters were observed. The results indicate significant variation in both types of parameters in onions exposed to test solution in comparison to control (tap water). The effects were dose dependent and more anomalies were observed at higher concentrations. Both Mitotic Index and root length response shows significant variation in treated groups in control to control groups. Chromosomal anomalies observed included ' lagging ' , ' chromosome bridges ' and ' sticky chromatin ' .

Abstract: Urban air pollution is worsening due to upward trends in power consumption, industrialization, vehicle use and scores of other development activities taken up by human beings. There are five major harmful substances, i.e.carbon monoxide, hydrocarbons, particulates, sulphur dioxide and nitrogen compounds released into the atmosphere in sufficient quantities as a result of natural events or by human activities. The quality of air with respect to SPM, SO2 & NOx around thermal power station in Sarni, district-Betul, M.P. has been assessed. Air quality deterioration due to large-scale coal mining, transportation and small scale utilization in the coal belt area of M.P. near ' Sarni ' has become matter of concern like any other industrial area in India. India is world ' s third largest coal- producing country. Hence, it is necessary to assess the air quality of the study area using air quality data. The air quality survey was carried out covering three seasons, i.e. summer, monsoon and post-monsoon during the year 2006. Results indicate that, ambient air quality levels are within permissible limits.

Abstract: The studies on removal of Vanadium were conducted using Ferronia elefuntum Fruit shell. Adsorption efficiency has been evaluated. The effect of pH, contact time, adsorbent dose, concentration of metal, particle size and temperature were studied. The results reveals that Langmuir and Freundlich isotherms are followed during adsorption process. Thermodynamics parameter indicate the feasibility of the process. Kinetic studies have been performed to understand the mechanism of adsorption.

Abstract: The oxides of nitrogen (NOx) and Carbon monoxide (CO) concentrations in ambient air in Tuticorin were estimated during January to March 2006. Statistical analysis on so generated database was performed to infer the dominance of meterological parameters affecting the pollution levels. The NOx and CO concentrations varied from 11.8 and 47.7mg/m3, 0.6 and 1.4 ppm respectively. From the collected database it was observed that, both NOx and CO levels were within the permissible limits set by the United States Environmental Protection Agency (US-EPA). It was also found that wind speed had major influence on the pollutant levels over the other parameters.

Abstract: Probability density functions were utilized to the 24 hour average concentrations of the pollutants like oxides of nitrogen (NOx), sulphur dioxide (SO2), respirable particulate matter (RPM) and suspended particulate matter (SPM) recorded from April to August 2006 in Thoothukudi, India and the distribution of levels of pollutants was performed. A non parametric goodness of fit test namely x2 test was also performed for the same datasets of the pollutant concentrations in the present investigation. It was observed that lognormal distribution was appropriate for the dataset pertaining to NOx, SO2 and RPM concentrations, whereas the normal distribution was appropriate for the dataset related to SPM concentrations. The distribution fitting so obtained for the dataset would be used not only for obtaining the percentage of concentrations falling in specific ranges but also framing suitable regulation measure and its subsequent implementation.

Abstract: The atmospheric dispersion models are playing an important role in predicting air quality around the industrial source complex, which governing the transport, dispersion, and transformation of pollutants in the atmosphere. Performance evaluation of these models is essential to assess their compatibility and accuracy. In this paper, the reliability of the model as assessed by applying historical meteorology, emissions and measured air quality of the specific industrial environment. A self-designed computer aided Gaussian Dispersion model namely, Multiple Point source Complex Short-Period (MPC_SP) model average concentraions model has been evolved and it is used for predicting the GLCs of short-term SO2 concentrations in the ambient environment of Indian Industrial Environment.

Abstract: Bacteriological quality has been evaluated for drinking water in Lucknow district, Uttar Pradesh, India at twenty differetn sites during Nov-Dec 2007. Drinking water at almost all the sites was found to be highly contaminated, except at a few sites. Alarmingly, the contamination was greater in the ground water as compared to the piped water supply. Source wise observation revealed that 66.6% piped water and 75% of ground water samples (Hand pumps) were found to be bacteriologically contaminated and unsafe for drinking purpose. Thus present study suggests that water samples are highly contaminated with feacal material, which may be taken as a source of gastrointestinal disease. It was observed that some effective measures are urgently required for periodic water quality monitoring with special emphasis on proper disinfections and maintenance of drinking water source.
