Abstract Three different types of microplastics (MPs): low density polyethylene; polypropylene; and polyester, were incubated for one and three months at two sites (Channel and Lake) in Muskegon Lake (MI). After retrieval, MPs were analyzed for polyaromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), organochlorine pesticides (OCs), select metals, and genomic characterization of the attached microbial biofilm. Polyaromatic hydrocarbons accumulated at similar levels on all microplastic types, but were ~one order of magnitude lower than sediment concentrations and ~three orders of magnitude lower than the Probable Effect Concentration (PEC): the concentration in sediment above which adverse biological effects are likely to occur. In contrast, PCB levels were 4–6× greater on polyethylene than on polypropylene or polyester, although all plastic-associated PCB concentrations were at least one order of magnitude less than the PEC. Organochlorine pesticide concentrations were very low (

马斯基根湖 (MI) 中与微塑料相关的持久性有机污染物、金属和细菌群落组成

摘要 三种不同类型的微塑料 (MPs)：低密度聚乙烯；聚丙烯; 和聚酯，在马斯基根湖 (MI) 的两个地点（海峡和湖）孵化了 1 个月和 3 个月。检索后，对 MP 进行了多环芳烃 (PAH)、多氯联苯 (PCB)、有机氯农药 (OC)、特定金属和附着微生物生物膜的基因组特征分析。聚芳烃在所有微塑料类型上的积累水平相似，但比沉积物浓度低一个数量级，比可能效应浓度 (PEC) 低~三个数量级：沉积物中的浓度高于该浓度可能会产生不利的生物效应发生。相比之下，聚乙烯的 PCB 含量比聚丙烯或聚酯高 4-6 倍，尽管所有与塑料相关的 PCB 浓度至少比 PEC 低一个数量级。有机氯农药浓度非常低（
