Commercially available butter from Spain (n = 36) and from other European countries (n = 20) has been analyzed by high resolution gas chromatography with an electron capture detector for organochlorine contaminants. The results showed that both groups of samples have a similar pattern of these pollutants, but in all cases where significant differences in concentrations were found, Spanish samples presented higher values. This was especially notable for lindane (median values 11.6 vs. 3.0 ng/g wet weight), hexachlorobenzene (6.4 vs. 0.5) and beta-hexachlorocyclohexane (3.1 vs. 1.2). Total PCBs showed no differences (5.4 vs. 6.6), but detailed analysis of congener composition indicated a higher presence in Spanish samples of the most persistent chlorinated PCBs. No sample presented levels of concern for any single organochlorine compound. It is interesting to note that consumption of butter in Spain is low so, although levels of organochlorines are higher than those found in other countries, consumers are less exposed through this foodstuff than in other European countries. These results also confirm the fact that environmental pollution by organochlorines is more important in Spain than in the rest of Europe.
已采用配备电子捕获检测器的高分辨率气相色谱法，对市售的来自西班牙的黄油（n = 36）和来自其他欧洲国家的黄油（n = 20）进行了有机氯污染物分析。结果表明，两组样品中这些污染物的分布模式相似，但在所有发现浓度存在显著差异的情况下，西班牙的样品数值更高。这在林丹（湿重中位数分别为11.6和3.0纳克/克）、六氯苯（6.4和0.5）以及β-六氯环己烷（3.1和1.2）方面尤为明显。多氯联苯总量没有差异（5.4和6.6），但对同系物组成的详细分析表明，在西班牙的样品中，持久性最强的氯化多氯联苯含量更高。没有任何一个样品中单一有机氯化合物的含量达到令人担忧的水平。值得注意的是，西班牙的黄油消费量较低，因此，尽管有机氯含量高于其他国家，但该国消费者通过这种食品摄入的有机氯比其他欧洲国家的消费者少。这些结果也证实了一个事实，即西班牙的有机氯环境污染比欧洲其他地区更为严重。
