三种不同类型的微塑料（MP）：低密度聚乙烯;聚丙烯;和聚酯，在马斯科贡湖（MI）的两个地点（海峡和湖泊）孵育一个月和三个月。检索后，MP进行了分析多环芳烃（PAH），多氯联苯（PCB），有机氯农药（OC），选择金属，和基因组特征的附着的微生物生物膜。多芳烃在所有微塑料类型上的积累水平相似，但比沉积物浓度低约一个数量级，比可能影响浓度（PEC）低约三个数量级：沉积物中的浓度高于该浓度可能发生不利的生物效应。相比之下，聚乙烯上的多氯联苯含量比聚丙烯或聚酯高4-6倍，尽管所有塑料相关的多氯联苯浓度至少比PEC低一个数量级。所有微塑料和所有地点的有机氯农药浓度都非常低（<1 ppb）。金属浓度也远低于其各自的PEC水平。最丰富的细菌群体的一部分的质体是伯克霍尔德菌，红环菌科，丛枝单胞菌科，假单胞菌科。聚酯微塑料含有更多数量的细菌家族，与其他塑料类型相比，这些家族的相对丰度分布更均匀。总体而言，我们的研究结果表明，持久性有机污染物能够在MP上积累，但浓度通常较低;需要进行饲养试验，以确定这些附着在微塑料上的污染物的环境现实浓度是否会对水生生物群产生影响。
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 (<1 ppb) on all microplastics and at all sites. Metal concentrations also were well below their respective PEC levels. The most abundant bacterial groups as part of the plastisphere were Burkholderiales, Rhodocyclaceae, Comamonadaceae, and Pseudomonadaceae. Polyester microplastics contained a higher number of bacterial families and the relative abundance of those families were more evenly distributed compared to the other plastic types. Overall, our results indicate that persistent organic pollutants are capable of accumulating on MPs but the concentrations generally were low; feeding trials are needed to determine if these environmentally realistic concentrations of pollutants attached to microplastics result in impacts to aquatic biota.
