2017年3月，在中国南海惠州海岸搁浅的怀孕抹香鲸的11个组织样本中测量了12种持久性有机污染物（POP）。持久性有机污染物在胎盘、卵巢、乳腺和肝脏等灌溉组织中的浓度高于表皮等灌溉较少的组织。在胎盘中检测到高含量的POP可能会导致胎盘中的激素分泌异常，从而影响未出生的后代。我们假设卵巢可能容易受到较高污染物水平的暴露。肺中的PAH浓度高于其他组织，这表明肺中的PAH水平在抹香鲸中具有呼吸依赖性。抹香鲸鲸脂中除多环芳烃外的其他持久性有机污染物浓度均低于北方半球同类鲸脂，与南半球同类鲸脂中的浓度相当或低于南半球同类鲸脂中的浓度。
Twelve persistent organic pollutants (POPs) were measured in 11 tissue samples from a pregnant sperm whale stranded on the Huizhou coast of the South China Sea, China, in March 2017. POPs were found to be more concentrated in the irrigated tissues such as placenta, ovary, mammary gland, and liver than the less irrigated tissues such as epidermis. High POP levels detected in the placenta might result in abnormal hormone secretion in the placenta, which would affect the unborn offspring. We hypothesized that ovary is potentially vulnerable to the exposure of higher contaminant levels. The PAH concentrations were higher in the lung than in other tissues, which suggest that PAH levels in the lung were breath-dependent in the sperm whale. The concentrations of POPs except PAHs in the sperm whale blubber were lower than those in the same species in the Northern Hemisphere and were comparable to or lower than those in the same species in the Southern Hemisphere.
