Values of analyzed parameters, namely, Na, K, Ca2+, pH, electrical conductivity, total dissolved solids, hardness, Mg2+, HCO, NO, PO3-, SO2- and Cl reported wide variations which ranged from 49.50-248.50 mg/l, 1.70-225.00 mg/l, 29.70-217.40 mg/l, 4.90-6.83, 257-2501 µS/cm, 170-1273 mg/l, 16-568 mg/l, 1.90-48.60 mg/l, 40-520 mg/l, 0.99-15.42 mg/l, 0.02-1.00 mg/l, 6.51-182.46 mg/l and 19-314 mg/l respectively. Analyzed results demonstrated roles of natural hydrogeochemical processes like weathering of silicates and carbonates and exchange of ions as well as human-made developmental activities responsible for affecting the groundwater quality. Anthropogenic control on groundwater chemistry emerged as a basic concern especially in the industrial areas, where some assessed parameters recorded much elevated levels. <#LINE#> @ @ Central Pollution Control Board (CPCB)., Findings: Problem Areas, Chapter IV, Ministry of Environment and Forests, Government of India, http://www.cpcb.nic.in.....

We are trying to analyse the variations in its analogues structurally. To study the QSAR of anthracycline analogues by using graph theoretical indices and physicochemical properties efforts have been made to derive a best mathematical model for the calculation of biological activity of the analogues in multivariate form. We have used multiple linear regression method. Two equations were developed separately, 1. Containing graph theoretical indices with r value 0.7038 and 2. Containing physicochemical properties as predictor variable with r value 0.8162 both models are significant to understand QSAR of anthracycline analogues. <#LINE#> @ @ Shaul P., Frenkel M., Breiner-Goldstein E., Mittelman L., Grunwald A., Ebenstein Y., Tsarfaty I., Fridman M., The structure of anthracycline derivatives determines their sub-cellular localization and cytotoxic activity, ACS Med.

The concentrations of trace metals in each fraction were determined using AANALYST 400 Perkin-Elmer AAS. The average concentrations (mg/kg) for the six metals in dry season sediment samples were 0.30 ± 0.09 (Cd), 2.28 ± 1.20 (Cu), 12.35 ±8.97 (Zn), 1.79 ± 0.74 (Ni), 3.52 ± 1.68 (Pb), and 2025.72 ± 304.43 (Fe), while the mean metal concentrations (mg/kg) in wet season samples were 0.29 ± 0.05 (Cd), 2.06 ± 0.74 (Zn), 24.57 ± 5.78 (Cu), 5.79 ±1.67 (Ni), 6.26 ± 3.73 (Pb), and 2534 ± 476.98 (Fe) respectively. Fe and Pb content in river sediments exceed the Federal Environmental Protection Agency (FEPA) regulatory Standards for soil. Chemical speciation study applying the five-stage sequential extraction schemes revealed that Cd in sediment prevails mostly in exchangeable fractions. Cu, Pb and Fe were more prevalent in residual fractions, while Zn and Ni were found more in carbonate, organic and residual fractions. Eco-toxicological assessment of the river sediments using the mobility factor indices reveals the following sequence: nickel � zinc � cadmium � copper � lead � iron in dry season and cadmium � nickel � zinc � lead � copper � iron in wet seasons respectively. Mobility factor indices for sediment metals revealed a high environmental contamination risk for nickel and cadmium, which indicate an environmental threat to the river ecosystem. <#LINE#> @ @ Petruzzelli G., Lubrano L. and Guidi G., Uptake by corn and chemical extractability of heavy metals from four years compost treated soil, Plant and Soil,16, 23 – 27 (1989) @No $ @ @ Rauret, G., Extraction procedures for the determination of heavy metals in contaminated soil and sediment, Talanta,46, 449–455 (1998) @No $ @ @ Van der Sloot H.A., Heasman L., Quevauviller, Ph.

This study aimed at evaluation of the quality of the disposed treated wastewater in order to find out the fate of the antibiotics in the city WWTPs. Antibiotics amoxicillin, ampicillin and ciprofloxacin concentrations ranged from below detection limits (bdl) to 0.367 mg/l and bdl to 0.037 mg/l were measured in wastewater influents and effluents samples, respectively. In all the WWTPs, effluents concentrations were lower than their corresponding influents. Variations in levels of antibiotics in WWTPs were considered to be attributed to removal efficiency of individual WWTP and antibiotics prescription patterns in different locations of the city, which determine or affect influent concentrations. All the parameters were measured by standard methods. <#LINE#> @ @ Kihampa C., Heavy metal contamination in water and sediment downstream of municipal wastewater treatment plants, Dar es Salaam, Tanzania, Intern.

The water resources around the world are being polluted due to multiple anthropogenic activities such as uncontrolled population growth, urbanization, industrialization and chemical intensive agriculture. The water body under investigation is Lower Lake of Bhopal, (M.P.), India. The water quality of Lower Lake is depleted to large extent as it receives huge amount of sewage by the nallas joining to it from various parts of the city. So for the conservation of lake various aeration units i.e. moving fountain, ozonizer and moving fountain along with ozonizer were fixed in the Lower lake. The physiochemical parameters like dissolved oxygen (DO), pH, chemical oxygen demand (COD) and biochemical oxygen demand (BOD) were examined to evaluate the performance efficiency of the aeration unit. <#LINE#> @ @ Sharma S., Vishwakarma R., Dixit S. and Jain P., Evaluation of Water Quality of Narmada River with reference to Physco- chemical Parameters at Hoshangabad city, MP, India, Res.

Defluoridation is very essential. Adsorption of fluoride from contaminated water is economic yet efficient method. Considering bioadsorbent for defluoridation is more beneficial than conventional adsorbents such as alumina, activated carbon etc., both in terms of quality and quantity. In our experimental studies, we have used dry biomass of Spirulina platensis as a bioadsorbent to defluoridate water samples. Based upon the multivariable studies pH, adsorbent dosage, initial fluoride concentration and contact time, we have found that in lab scale, at pH 5 and adsorbent dosage of 1.0g/100ml and at the fluoride concentration of 20 mg/l, maximum adsorption (97.10%) takes place. Langmuir isothermal model suits well for the adsorption of fluoride from water using Spirulina as bioadsorbent. The FTIR spectroscopy results were also checked to know the cause of adsorption. <#LINE#> @ @ World Health Organization Guidelines for drinking-water quality, 1, (1993) @No $ @ @ World Health Organization Guidelines for drinking-water quality, 2, (1999) @No $ @ @ Srimurali, M., Pragathi, A. and Karthikeyan, J., A study on removal of fluorides from drinking water by adsorption onto low-cost materials, Environmental Pollution, 99, 285-289 (1998) @No $ @ @ Jagtap, Sneha, Mahesh Kumar Yenkie, Nitin Labhsetwar, and Sadhana Rayalu., Fluoride in Drinking Water and Defluoridation of Water,Chemical Reviews, 112(4), 2454-66 (2012) @No $ @ @ Alagumuthu G., Veeraputhiran V. and Venkataraman R., Adsorption Isotherms on Fluoride Removal: Batch Techniques, Scholars Research Library Archives of Applied Science Research, 2(4), 170-185 (2010) @No $ @ @ Hong C. and Pan S., Bioremediation potential of spirulina: toxicity and biosorption studies of lead, Journal of Zhejiang Science University6B (3), 171-174 (2005) @No $ @ @ Bhargava D.S. and Killedar D.J., Batch studies of water defluoridation using fish bone charcoal, Res.

Atmospheric corrosion can aggressively accelerate the rate of degradation of steel during their manufacturing, processing, storage and transportation. In these cases, traditional methods to prevent corrosion are not suitable which provide scope of Vapour Phase Corrosion Inhibitors (VPCI) in industries, defense and daily life. N, N, N, N-Tetramethylethylenediamine (TMEDA) and 1, 3-Diaminopropane (DAP)were investigated as VPCI for mild steel under aggressive corrodents of atmosphere by Weight loss test, Eschke test, Salt spray test, Sulphur dioxide (SO) test at 50C and results of these tests were supported by Metallurgical research microscopy technique and SEM technique. <#LINE#> @ @ Corvo F., Atmospheric Corrosion of Steel in Humid Tropical climates: Humidity, TemperatuSun Radiation, Corros, 40, 4 (1984) @No $ @ @ Morcillo M., Chico B., Otero E. and Mariaca L., Effect of Marine Aerosol on Atmospheric Corrosion, 38(4), 24 (1999) @No $ @ @ Ericsson R., The influence of SOHumidity on the Atmospheric Corrosion of Steel, Korros., 29, 400 (1978) @No $ @ @ Blucher B.D., Lindstrom R., Svensson J.E. and Johansson L.G., The effect of COon the NaClCorrosion of Aluminum, J.

The result obtained showed significant difference in SLS and SHN concentrations in the sampled toothpastes. The concentration of the SLS sampled toothpastes ranged from 1.56×10 ± 10.11 mg/Kg to 2.13×10 ± 10.22mg/Kg while that of the SHN ranged from 833×10 ±17.29 mg/Kg to 2.32×10 ± 11.47mg/Kg. The result obtained from the analysis of SLS in the toothpaste samples shows that T2 also had the highest concentration of 2.13×10 ±10.22 mg/Kg while T8 had the lowest concentration of 1.56×10± 10.11 mg/Kg.The concentration of SHN in the toothpastes are unacceptable when compare to the daily acceptable intake (ADI) established by regulatory agencies. This implies that these toothpastes could be a potential poison to consumers especially the vulnerable children that have the tendency for uncontrollable intake. <#LINE#> @ @ Barnes G.T. and Gentle I.R., Interfacial Science, Oxford University Press Oxford (2005) @No $ @ @ Kumar H. and Sunita., ADS, ALS, AHDS and ADDBS Surfactants as Corrosion Inhibitors for Carbon Steel in acidic Solution, Res.J.Chem.Sci.2(7), 1-6 (2012) @No $ @ @ Babich H. and Babich I.P., Sodium lauryl sulphate and triclosan, invitro cytotoxicity studies with gingival cells, Toxicol.

Fluoride accumulates in bones and teeth in the form of fluorapatite which causes the bones to become brittle. Oral intake of fluoride higher than 1.0 to 1.5mg/L results in skeletal and dental fluorosis. Batch experiments were carried out to investigate the removal of fluoride from acid treated water by using calcite as the adsorbent. The effect of calcite dosage with different concentrations of acetic acid on defluoridation capacity was evaluated. The removal efficiency of fluoride increased with increase in the dose of calcite. Calcite is found to be a very low cost material and treating it with 0.05M acetic acid has resulted in increasing the defluoridation capacity to 75.6%. For a dosage of 7gm/l of calcite used for treating water with acetic acid the removal was 65.03% and the pH of treated water was observed to be 6.7 to 7.4 which makes it fit for drinking purposes. Results obtained depicted that the defluoridation is due to both adsorption and precipitation processes. It was found that the acidified water was neutralized by calcite and the pH of treated water was in the range of 6.7 to 7.4 after treatment. This study indicated that calcite is a very low cost adsorbent and can be used as a defluoridation agent. <#LINE#> @ @ World Health Organization, Guidelines for drinking water quality, 3rd Edition, WHO, Geneva, (2004) @No $ @ @ Aoba T. and Fejerskov O., Dental fluorosis: chemistry and biology, Crit.

There are various biosorbent available which are efficient in removing heavy metals. The present study successfully assess the potential of dried powder of hyacinth root (Eichhornia Crassipes (Mart.) Solms), referred as dried hyacinth root (DHR), by determining the effective size and pH at which it is capable of removing arsenite (As III) efficiently. At different size and pH, the experiment was conducted. Results from ICP-OES suggest that at 0.063mm, and at pH 6.2 to 8.2, DHR was more effective in mitigation of arsenic whereas at bigger size, that is, 4.1 mm, and at pH 2.2 and 4.2, DHR was not very effective. It is concluded that at finer size (0.063 mm), and at pH 6.2 to 8.2, DHR have more potential to remove arsenic from water. <#LINE#> @ @ Gonzalez H, Lodenius M, Otero M..

The reaction was found to be very rapid and of second order having a half-life of 40 seconds and velocity constant 5000 M -1s -1 at 30°C. The rapidity of the reaction necessitated the use of a special technique, hydrodynamic voltammetry, to follow the course of the reaction. The energy of activation , entropy of activation and pre-exponential factor ‘A’ for the reaction are evaluated as 56.16 kJ mol-1 , -64.35 J K-1mol-1and 6.96 x 10 M -1-1respectively at 30°C and 7 pH. The kinetic and related thermodynamic data obtained elucidate the high reactivity of the heterocycle under study. <#LINE#> @ @ Bonde S.L., Dangat V.T., Borkar V.T. and Yadav R.P., Rapid Iodination of Xylidines in Aqueous Medium: Kinetic verification of Speculated Reactivities Res.J.chem.sci., 2(6), 1-5 ( 2012) @No $ @ @ Naidu A.B., Ganapathy D., Sekar G., Cu (I) Catalysed Intramolecular C (aryl)-Bond Forming Cyclization of the Synthesis of 1,4-Bezodioxins and its Application in Total Synthesis of Sweetening Isovanilines, Synthesis 3509, 2010) @No $ @ @ Hernandes M.Z., Cavalcanti S.M.T., Moreira D.R.M., de Azevedo W.

The reaction followed first-order kinetics with respect to [HAs] and [2-27CrO]. The kobs values are found to be independent on pH values lower than pH = 6 and higher than pH = 9. Increased cationic CTAB concentration found to increase kobs values whereas those of AOT decrease the kobs values. The effect of added anions, such as chloride, bromide, and iodide has been studied and discussed. The activation parameters and were also evaluated. <#LINE#> @ @ Fendler J.
