Integrated analysis of halogenated organic pollutants in sub-millilitre volumes of venous and umbilical cord blood sera.

the samples. Small volumes of reference serum between 50 and 1000 μL were extracted and the limits of detection/ quantification and repeatability were determined. Recoveries of spiked compounds for the extraction of small volumes (≥300 μL) of the spiked reference serum were between 90% and 120%. The coefficients of variation of repeatability ranged from 0.1–14%, depending on the compound. Samples of 4-year-old serum and umbilical cord blood (n=73 and 40, respectively) from a population inhabiting a village near a chloro-alkali plant were screened for the above-mentioned halogenated pollutants using this method and the results are briefly described.the samples.
