A risk assessment framework for direct exposure of residual additives and monomers present in ingested plastic particles, including microplastics, in the Danish marine environment, was presented. Eight cases of different polymer types and product groups were defined that represent the most significant exposures, and thus potential high-risk cases, towards marine organisms. Risk Quotients (RQ) were calculated for three trophic levels, i.e. pelagic/planktonic zooplankton: copepod, benthopelagic fish: Atlantic cod and seabird: northern fulmar. European and Danish Environmental Quality Standard (EQS) values were used as Predicted No-Effect Concentrations (PNEC). RQ larger than unity, indicating potential risks, were found for copepod and cod (pelagic community) and the flame-retardant pentabromodiphenyl ether (PeBDE) used in polyurethane (PUR), the biocide tributyltin (TBT) present as impurity in polyvinylchloride (PVC) and PUR, and the flame-retardant hexabromocyclododecane (HBCDD) used in expanded polystyrene (EPS). A potential risk was found for fulmar (secondary poisoning) and PeBDE used in PUR.

提出了在丹麦海洋环境中直接暴露摄入的塑料颗粒（包括微塑料）中残留的添加剂和单体的风险评估框架。定义了八种不同聚合物类型和产品类别的案例，它们代表了最重要的海洋生物暴露量，因此是潜在的高风险病例。计算了三个营养级的风险商（RQ），即上层/浮游性浮游动物：pe足类，底栖鱼类：大西洋鳕和海鸟：北ful。欧洲和丹麦的环境质量标准（EQS）值用作预测的无影响浓度（PNEC）。对于co足类和鳕鱼（浮游生物群落）和聚氨酯（PUR）中使用的阻燃五溴二苯醚（PeBDE），发现RQ大于1，表明存在潜在风险，杀菌剂三丁基锡（TBT）作为杂质存在于聚氯乙烯（PVC）和PUR中，以及用于膨胀聚苯乙烯（EPS）的阻燃六溴环十二烷（HBCDD）。发现在PUR中使用（继发中毒）和五溴二苯醚的潜在风险。
