Abstract Background In the past, cases of PCDD/F and PCB contamination exceeding limits in food from animal origin (eggs, meat or milk) were mainly caused by industrially produced feed. But in the last decade, exceedances of EU limit values were disc

The semi-experimental approach to approximating physicochemical data relevant to environmental distribution (vapor pressure and gas-octanol distribution) by correlation with gas chromatography (GC) retention data has been extended to the determinatio

We estimated Kow values that are usually derived by liquid chromatography solely from gas chromatographic (GC) data by selective correlation with PCB congeners as secondary standards. The GC method was established and validated with literature-known

Levels and patterns of C1C4/C9 organic nitrates were measured for the first time in Antarctica. The sampling wasdone by adsorptive enrichment on Tenax TA followed by thermodesorption cold-trap high resolution capillary gaschromatography with electron
