塑料颗粒的平均浓度为每平方公里3500片和290克，广泛分布在马尾藻海西部。碎片很脆，显然是由于增塑剂的风化，许多碎片呈颗粒状，直径约0.25至0.5厘米。颗粒是硅藻和水合物附着的表面。塑料产量的增加，再加上目前的废物处理做法，无疑将导致这些颗粒浓度的增加。塑料可能是最近在海洋生物中观察到的一些多氯联苯的来源。
Plastic particles, in concentrations averaging 3500 pieces and 290 grams per square kilometer, are widespread in the western Sargasso Sea. Pieces are brittle, apparently due to the weathering of the plasticizers, and many are in a pellet shape about 0.25 to 0.5 centimeters in diameter. The particles are surfaces for the attachment of diatoms and hydroids. Increasing production of plastics, combined with present waste-disposal practices, will undoubtedly lead to increases in the concentration of these particles. Plastics could be a source of some of the polychlorinated biphenyls recently observed in oceanic organisms.
