Characterization of Ambient Methyl Mercaptan in Sipcot Industrial Complex, Cuddalore
نویسندگان
چکیده
In Industrial complex, major air pollutants like SO2, NOx, SPM, RPM and CO concentrations were standardised. Some site specific air pollutants like fluoride, H2S, methyl mercaptan, hydrogen chloride, vinyl chloride, etc., were also emitted from industries. Methyl mercaptan is a site specific air pollutant in SIPCOT Industrial complex, Cuddalore, TamilNadu. The presence of methyl mercaptan in the ambient air in and around the study area was identified by conducting a one-day monitoring. In this study, it is aimed to characterize the ambient concentration levels of methyl mercaptan in the SIPCOT Industrial complex. The air monitoring study was carried out continuously for 20 consecutive days for 3 seasons (winter, summer and monsoon) in 2011 & 2012. The observed concentrations were characterized for daily pattern and for DayNight / Sea & Land breeze effects. The results indicate that the concentrations were in the detectable range during all the seasons and also shows, the concentration levels were low after the onset of the sea-breeze.

Assessment of odorous VOCs released from a main MSW landfill site in Istanbul-Turkey via a modelling approach.
An air pollution modeling study was conducted to investigate the odorous effects of volatile organic compounds (VOCs) emissions from a sanitary landfill area on ambient air quality. The atmospheric dispersion of hydrogen sulfide (H(2)S) and 22 VOCs was modeled. Industrial Source Complex v3 Short Term (ISCST3) model was used to estimate hourly concentrations of odorous VOCs over the nearest resi...

Small silver clusters (average diameter of 1.2 nm) protected by 4-(tert-butyl)benzyl mercaptan (BBSH) were converted to stable, monodisperse clusters (2.1 nm) by a ripening process with excess amount of BBSH. Multiple characterizations of the isolated magic clusters revealed an approximate chemical composition of Ag(∼280)(SBB)(∼120).

Long-chain n-octadecayl mercaptan (C18H37SH)-passivated palladium nanoparticles are synthesized and characterized. The palladium nanoparticles are successfully capped by n-octadecayl mercaptan. These palladium nanoparticles have the same face-centered cubic crystalline structure as Pd in the bulk phase. The size of the capped palladium nanoparticles varies in the range of 1.3–5.5 nm for various...
