Plastic pellets found stranded on beaches are hydrophobic organic materials and thus, they are a favourable medium for persistent organic pollutants to absorb to. In the present study, plastic pellets are used to determine the diffuse pollution of selected Greek beaches. Samples of pellets were taken from these beaches and were analyzed for PCBs, DDTs, HCHs, and PAHs. The observed differences among pellets from various sampling sites are related to the pollution occurring at each site. Plastic pellets collected in Saronikos Gulf beaches demonstrate much higher pollutant loading than the ones collected in a remote island or close to an agricultural area. Based on data collected in this study and the International Pellet Watch program, pollution in Saronikos Gulf, Greece, is comparable to other heavily industrialized places of the world. The present study demonstrates the potential of pellet watch to be utilized as a detailed-scale monitoring tool within a single country.
在海滩上发现的塑料颗粒是疏水性有机物质，因此，它们是持久性有机污染物吸收的理想介质。在本研究中，使用塑料颗粒来确定选定的希腊海滩的扩散污染。从这些海滩采集了颗粒样本，并对其进行了多氯联苯、滴滴涕、六氯环己烷和多环芳烃的分析。不同采样点的颗粒之间的差异与每个采样点的污染有关。在萨罗尼克湾海滩收集的塑料颗粒显示出比在偏远岛屿或靠近农业区收集的颗粒更高的污染物负荷。根据本研究和国际颗粒观察计划收集的数据，希腊萨罗尼克湾的污染与世界上其他工业化程度较高的地区相当。本研究表明，颗粒观察有潜力作为一种在单个国家内进行详细规模监测的工具。
