Quantitative Determination of Urinary Metabolites o-Dichlorobenzene Using a Gas Chromatograph of
o-Dichlorobenzene (o-DCB) is used as an organic solvent, as a chemical intermediate, and as a heat transfer medium. In humans, o-DCB is metabolized to 2,3and 3,4-dichlorophenols, and 3,4and 4,5-dichlorocatechols, and these metabolites are eliminated via the kidneys. In this study, we tried to determine the concentrations of urinary 2,3and 3,4-dichlorophenols using a gas chromatograph (GC). When...
متن کاملSimultaneous determination of urinary estriol, pregnanediol, and pregnanolone by gas-liquid chromatography.
A simplified method for following the urinary excretion of estriol, pregnanediol, and pregnanoloneduring the course of pregnancy is presented. The procedure has been used successfully in a large hospital laboratory. An important advantage is that the estrogen and progesterone metabolites are measured simultaneously, and separate extraction and gas-liquid chromatographyis not required. The urine...
متن کاملSimultaneous determination of pregnanediol and pregnanolone in urinary extracts by gas chromatography.
HAVE ltEl’ORTED a comparison of methods for determining urniary pregnanediol and have shown that enzymatic hydrolysis of preglianelhiOl conjugate, preliminary purification using silica gel chromatography, anti gas chromatographic quantitation was the prefered method (1). hi this report we show a simple modification of this procedure that enables the simultaneous determination of pregnanediol ($...

شناسایی مخاطرات در واحد 400 پالایشگاه گاز پارسیان. در این پروزه با بکارگیری از تکنیک hazop به شناسا یی مخاطرات ، انحرافات ممکن و در صورت لزوم ارایه راهکارهای مناسب جهت افزایش ایمنی فرا یند پرداخته میگردد. شرایط عملیاتی مخاطره آمیز نظیر فشار و دمای بالا و وجود ترکیبات مختلف سمی و قابل انفجار در واحدهای پالایش گاز، ضرورت توجه به موارد ایمنی در این چنین واحدهایی را مشخص می سازد. مطالعه hazop یک ر...
A method for on-site analysis of urinary benzene by means of a portable gas-chromatograph.
Benzene is one of the toxic air pollutants released from automobile fuel, exhaust, tobacco smoke etc., and is commonly found in both indoor and outdoor air. Since benzene is a carcinogenic substance classified into group 1 (carcinogenic to humans) by the International Agency for Research on Cancer (IARC), it is important to assess the human health risk posed by exposure to environmental or occu...
