Reports outline life sciences study findings from University of Hohenheim, Institute of Food Chemistry

Scientists discuss in 'Stable carbon isotope ratios of POPs--a tracer that can lead to the origins of pollution' new findings in life sciences. "An elemental analyzer in combination with stable isotope ratio mass spectrometry (EA-IRMS) was used to demonstrate that two samples of the chloropesticide Melipax discovered in two countries varied only by 0.1 per thousand in their delta 13C values. Gas chromatography interfaced to a stable isotope mass spectrometer (GC-IRMS) was used to study the delta 13C values of individual congeners in two technical polybrominated diphenyl ether products, i. e," scientists in Stuttgart, Germany report.

"DE-71 and DE-79, at three different...
