An epizootic of morbillivirus infection killed several hundred common seals (Phoca vitulina) along the coast of Northern Ireland in 1988. Many dead and moribund seals were submitted to the Department of Agriculture for Northern Ireland, Veterinary Research Laboratories for necropsy. Samples of blubber, liver and kidney were collected from these animals (n = 55) for analysis for a wide range of organochlorine pesticides and also total polychlorinated biphenyls (PCBs). The organochlorines found in highest concentrations in blubber were PCBs which were detected in all samples (mean, 26 micrograms g-1 wet wt). sigma DDT (mean, 2.63 micrograms g-1 wet wt) and chlordane (mean, 0.22 micrograms g-1 wet wt) were also present in all samples. Heptachlor including heptachlor epoxide (mean, 0.13 micrograms g-1 wet wt) was present in over 93% of samples. Seventy-four percent of samples contained alpha HCH (mean, 0.035 micrograms g-1 wet wt), 50% contained beta HCH (mean, 0.026 micrograms g-1 wet wt) while gamma HCH (mean, 0.012 micrograms g-1 wet wt) was detected in 46% of samples. The organochlorine concentrations found in this study are at the lower end of the range previously reported for European common seals.
1988年，一场麻疹病毒感染的 epizootic 疫情导致北爱尔兰海岸数百只普通海豹（港海豹）死亡。许多死亡和濒死的海豹被送往北爱尔兰农业部兽医研究实验室进行尸检。从这些动物（n = 55）身上采集了脂肪、肝脏和肾脏样本，用于分析多种有机氯农药以及总多氯联苯（PCBs）。在脂肪中发现浓度最高的有机氯是多氯联苯，所有样本中均检测到（平均，26微克/克湿重）。所有样本中还存在σ-DDT（平均，2.63微克/克湿重）和氯丹（平均，0.22微克/克湿重）。包括环氧七氯在内的七氯（平均，0.13微克/克湿重）存在于超过93%的样本中。74%的样本含有α-六氯环己烷（平均，0.035微克/克湿重），50%的样本含有β-六氯环己烷（平均，0.026微克/克湿重），而46%的样本中检测到γ-六氯环己烷（平均，0.012微克/克湿重）。本研究中发现的有机氯浓度处于先前报道的欧洲普通海豹浓度范围的下限。
