The occurrence of plastic objects in the digestive tract was assessed in eight species of Procellariiformes collected in southern Brazil and the occurrence of polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) in the ingested plastics pellets and plastic fragments was evaluated. PCBs were detected in plastic pellets (491 ng g(-1)) and plastic fragments (243-418 ng g(-1)). Among the OCPs, p,p'-DDE had the highest concentrations, ranging from 68.0 to 99.0 ng g(-1). The occurrence of organic pollutants in post-consumer plastics supports the fact that plastics are an important source carrying persistent organic pollutants in the marine environment. Although transfer through the food chain may be the main source of exposure to POPs to seabirds, plastics could be an additional source for the organisms which ingest them, like Procellariiformes which are the seabirds most affected by plastic pollution.
在巴西南部收集的 8 种海燕目鸟类中评估了消化道中塑料物体的出现情况，并评估了摄入的塑料颗粒和塑料碎片中多氯联苯 (PCBs) 和有机氯农药 (OCPs) 的存在情况。在塑料颗粒（491ng/g）和塑料碎片（243-418ng/g）中检测到 PCBs。在 OCPs 中，p,p'-DDE 浓度最高，范围为 68.0 至 99.0ng/g。消费后塑料中有机污染物的存在证实了塑料是海洋环境中持久性有机污染物的重要载体。尽管通过食物链转移可能是海鸟接触持久性有机污染物的主要来源，但塑料可能是摄入它们的生物的另一个来源，如海燕目鸟类，它们是受塑料污染影响最大的海鸟。
