Study on Evaluvation of Benzo (a) Pyrene Soluble Fraction in Respirable Suspended Particulate Matter in Peenya Industrial Area by GCMS

Abstract Polycyclic aro matic hydrocarbons (PAHs) were identified to be one of the major to xic air pollutants in urban environment. PA Hs are mostly formed during incomp lete combustion or pyrolysis of organic material. According to National ambient air quality Indian standard, benzo (a) pyrene (BaP) concentration Part iculate matter (PM 10 ) in amb ient air in the Peenya industrial area Bangalore met ropolitan in India has been determined. Air samp les for the analysis of BaP in suspended particles have been collected (as 24 h sample once in a month) at selected monitoring sites within the Peenya industrial monitoring network. In this research work, the results of PM 10 were collected between February 2011 and April 2011. The Ben zo(a)pyrene concentrations of the eight sampling sites ranged fro m zero to 0.0490ng/ m 3 . Spatial variations were predo minantly due to the different strengths of source emission. The total Benzo (a)pyrene concentrations at Kongovi Monitoring Station site was higher than those at other seven sites during monitoring period, observing the results obtained during the period of a whole year, it was concluded that, the concentrations of BaP were much h igher during winter season at almost all measuring sites

TEXTILE MILL WASTEWATER TREATABILITY STUDIES BY SOIL AQUIFER TREATMENT SYSTEM IN CONJUNCTION WITH NATURAL ADSORBENTS

Water resources around the world are under increasing pressure from the rapidly growing demands of rising population and industrialization. It is not only the depletion of quantity but also the quality is deteriorating due to indiscriminate discharge of untreated industrial waste waters and sewage generated from the community. Therefore treatment of wastewater for disposal and reuse is necessary for safe and sustainable environment. Several treatment techniques are adopted for better management of wastewater. In the present study Soil Aquifer Treatment System is adopted for wastewater reclamation for potable and non-potable uses. Textile Mill wastewater was used for experimentation to assess the treatment efficiency of SAT system in treating these wastewaters under varied experimental conditions. Clayey sand and silty sand are the two soils used for experimentation along with the Peepal leaf and Almond leaf has the adsorbents. Removal efficiency of chloride BOD and COD was maximum in clayey sand in conjunction with peepal leaf has adsorbent. Where in Colour and TDS removal was maximum in clayey sand when compared to silty soil and soils in conjunction with adsorbents
