Opis:: The aim of this paper is to localize the fugitive leaks from the above ground facilities of the existing system of Titas Gas (TG) after developing mathematical model for fugitive emission. Soap screening techniques and Gasurveyor 500 series instrument were used in this study for detecting potential leaks. Leaked gas was quantified using either Hi-Flow gas sampler or bagging measurements system. The results show that the respective potential gas leaking point of City Gate Station (CGS), commercial Regulating and Metering Station (RMS), industrial RMS, residential RMS and Town Bordering Station (TBS)/ District Regulating Station (DRS) are scrubber dump valve (average leak rate 217.00 L/min), insulating point (average leak rate 4.04 L/min), tube fitting connector (average leak rate 8.00 L/min), connector (average leak rate 1.55 L/min) and pressure relief valve (average leak rate 437.92 L/min). Fugitive methane emission can be reduced by stopping leaks of fittings or components having high K_Leak value.

Opis:: The aim of this work is to detect and estimate the level of selected heavy metals (copper and lead) in milk and milk products in Chittagong City Corporation Areas of Bangladesh. The most important milk and milk products that are likely to be an important contributor to heavy metal exposure was selected. Total 30 samples of milk and milk products were analyzed among these 20 raw milk samples was collected from 20 dairy farms around industrial area in Chittagong City and 10 milk product samples were collected from market in Chittagong City. Detection and estimation of the level of copper and lead were carried out by using “Analytikjena Atomic Absorption Spectrophotometer, model: ZEEnit700P, Germany”. It was found that, most of all milk samples contain copper and lead copper and lead. The content of copper in most of all raw milk and milk products were in the range from 0.02 mg/kg to 0.25 mg/kg. The highest level of copper was found 0.244 mg/kg in milk products. The concentration of lead in milk and milk products were in the range from 0.007 mg/kg to 0.02 mg/kg. The highest concentration of lead was found 0.019 mg/kg in raw milk. These values were compared with standard allowable limit and also with the corresponding values of different countries available in literature.
