Resin pellets as a raw material of industrial plastic products are widespread on the coastal water and beaches in the world. In this study, resin pellet pollution on the coastal area of Tokyo Bay and Sagami Bay were investigated.In most stations surveyed, resin pellets were found (93% of total stations) and particularly abundant at Kugenuma Beach, Nojima Seaside Park, Jonanjima Seaside Park and Kasai Seaside Park. Highest density was more than 1,000 per square meter.From the analyses of near infra-red spectrometry, the pellets on most beaches were found to be comprised mostly of polyethylene (60%) and polypropylene (35%) which were very common constituents of plastic production in Japan.From the survey results of sea-surface and river, the influence of effluent from plastics manufacturers was suggested to be the major sources for the pellets stranding on coastal areas of Tokyo Bay and Sagami Bay.Gas chromatograph Chemical analysis Organic pollutants in resin pellets collected from some beaches and coastal waters were analyzed by gas chromatography (GC/MS). PCB, DDE, nonylphenols (NP) and bisphenol-A (BPA) as well-known toxic chemicals were detected. Their concentration in 1g of pellet sample (polyethylene and polypropylene) were as follows : PCBs (4-117ng/g), DDE(0.16-3.1ng/g), NP(0.13-16μg/g) and BPA(13.6-1628ng/g).From these chemical analyses, it was suggested that resin pellets may serve as a carrier of toxic chemicals in the marine environment.

在世界沿海水和海滩上，树脂颗粒是一种在东京湾湾和萨加米湾的沿海地区的塑料产品。在Kugenuma Beach，Nojima Seaside Park特别丰富的电台。从近红外光谱法分析，大多数海滩的颗粒都大多是聚聚乙烯（35％），大多数海滩上的颗粒都超过每平方米。这是日本非常常见的普遍异常离子。从海面和河流的调查结果，塑料制造业的污水的影响是曾经是曾经是曾经是曾经是曾经是曾经是曾经的事物当时是当时是当时是当时是当时是当时是当时是当时是当时是曾经是。从某些海滩中收集的树脂颗粒中的LLUTANS和沿海地区（GC/MS）分析如下：PCB（4-117 ng/g），DDE（0.16-3.1 ng/g），NP（0.13-16μg/g）和BPA（13.6-1628NG/g）。海洋环境中的树脂化学物质。
