Keywords: Humic acid model, ammonia, chlorination, lactam
Abstract: The data in this paper show that pentachlororesorcinol (2,2,4,4,6-pentachloro-5-cyclohexen-1,3-dione, PCR, 1), a humic acid model compound, reacts with ammonia, NH3 in ether to form an unexpected lactam (4). Mass spectra, x-ray crystallographic data and other evidence are presented that establish the structure of 3, 3, 5-trichloro-6- [dichloro (hydroxy) methyl] -5,6-dihydropyridin-2 (1H)-one (4). The proposed mechanism of reaction suggests that I reacts with NH3 in ether via a nucleophilic attack on the carbonyl of 1 along with an internal rearrangement to form 4.

Keywords: In-silico study, N-(furan-2-yl methyl)-2-(1H-tetrazol -5-yl) acetamide, Lipophilicity, ADME, drug likeness
Abstract: In present work, drug likeliness of N-(furan-2-yl Methyl)-2-(1 H-tetrazol -5-yl) acetamide and its 14 hypothetical analogues based on toxicity, lipophilic city, solubility and molecular weight were calculated by Osiaris molecular property explorer, Lipophilicity of N-(furan-2-yl methyl)-2-(1H-tetrazol-5-yl) acetamide is low (only injectable drug can be designed from it). To design a drug candidate of high lipophilicity so that it can be taken orally, hypothetical analogues were prepared keeping in mind to increase their lipophilicity, optimize their drug target interaction, fulfilling ' ADME ' criterion as well as Lipinski Rule of 5. Osiaris predicts mutagenic, tumerogenic, irritant and reproductive effects qualitatively and lipophilicity, solubility, molecular weights quantitatively on atom type based increment system. Drug likeness was predicted based on atom fragment based contribution. Over all drug score combines all other into one grand total. Heat of formation and Lipophilicity of all analogues are also calculated by CHEM PRO 8.0. In early stages of designing an anti inflammatory and analgesic drug based on N-(furan-2-yl methyl)-2-(1H-tetrazol-5-yl) acetamide, it is beneficial to do this in-silico study before synthesis work is under-taken with the aim of avoiding the synthesis of compounds that are predicted to have poor bio-pharmaceutical characteristics.

Keywords: 2,4 DNP, degradation, factorial design, modeling, modified fenton, multivariate approach
Abstract: 2,4 dinitrophenol (2,4 DNP) is a priority pollutant that may enter environment from petrochemical, textile and dye stuff manufacturing. Due to ineffectiveness of biological processes in treatment of such a waste, advanced oxidation process (AOP) as a promising alternative has been introduced. Modified fenton process is an AOP process. The objective of this study is modeling of DNP degradation by modified fenton process, in this regard a full factorial environmental design was performed with H 2 O2 and Fe3+ concentration and also reaction time as the most important variables. The results show that the reaction time is very influential variable while H 2 O2 and Fe3+ concentration alone are much less important for the confidence level selected. The results also show that for High H 2 O2 concentration, higher Fe+3 concentration leads to lower degree of degradation due to catalytic effects of Fe+3 on the decomposition of H 2 O2 to H 2 O and O2 . Finally a mathematical model has been proposed to estimate DNP degradation. Comparison of experimental results with proposed model shows the similarity in majority of experiments. The predicted model satisfactory describes the modified-Fenton process in DNP degradation.

Keywords: Solid-phase extraction, polycyclic aromatic hydrocarbons, sterols, pentachlorophenol
Abstract: In this study, a rapid and selective solid-phase extraction (SPE) by stacking two cartridges, octadecyl bonded silica (C18 ) and polymeric sorbents (LiChrolut EN or Isolute ENV +) for the determination of organic compounds (polycyclic aromatic hydrocarbons (PAHs), chlorpyrifos, sterols, phenol and pentachlorophenol) in water was developed. The non polar and moderately polar compounds were trapped in the C18 sorbent while the more polar compounds were trapped in the polymeric sorbent. Using C18 acceptable recoveries of non polar compounds. PAHs (84.4 - 101.5%) and chlorpyrifos (99.4%) were obtained in first elution with n-hexane while moderately polar compounds, sterols (89.7-98.6%) were recovered in the second elution using stronger eluting solvent (DCM). Factors affecting the recoveries of the target analytes such as addition of organic modifier to the sample, pH of sample and types of eluting solvent were considered. The presence of 10% (v/v) methanol was most appropriate for the enrichment of PAHs (3-6 rings), chlorpyrifos and sterols on C18. Acceptable recoveries (94.8-100.8%) of the more polar compounds (phenol and pentachlorophenol) from polymeric sorbents were achieved using DCM as the eluting solvent. The developed approach is able to shorten analysis time for the analysis organic compounds over a wide polarity range in water.

Keywords: Anthropogenic, backwaters, coastal ecosystem, coral reefs, estuaries, eutrophication, lagoons nad mangroves
Abstract: The Union Territory of Puducherry has a coastline of 45 km, stretching along the Bay of Bengal and to some extent along the Arabian Sea. Out of which Puducherry region alone has 24 km of coastline, Karaikal has 20 km stretch and Mahe has 1 km stretch of coastline. The U.T. also has 675 sq. km of inshore waters. It has a very wide range of coastal ecosystems such as estuaries, lagoons, mangroves, backwaters, salt marshes, rocky coasts, sandy stretches and coral reefs, which are characterized by unique biotic and abiotic properties and processes. A total of 7 mangrove floral species belongs to 3 families, 16 of its associates floral species described under 12 families, 15 each of molluscs & crustaceans, 39 species of fish species under 24 families, 14 species of birds under 10 families were reported during the period of 2005. In the findings date backs to 2002, existence of 13 true floral species of mangroves associated by 72 species of flora and fauna were reported. Six mangrove species and its associates of 33 fish species were reported to be extinct. 15 bird species and 42 fish species were also recorded as coastal animals because of its sensitiveness, coastal ecosystems are highly degraded due to anthropogenic activities, eutrophication, sewage and industrial pollution, thermal and nuclear pollution besides natural hazards like tsunami and Hurricanes etc. It was evident that Coastal ecosystem in UT of Puducherry is getting fast degraded and there is an urgent need of developing system tool to sustain, conserve and protect the coastal ecosystem in UT of Puducherry. An attempt has been made in this review to study the function and structures of coastal ecosystem in UT of Puducherry and possible measures on ecosystem management were documented and database development on this line by ENVIS Puducherry is suggested.
