研究了安大略湖沉积物中的微塑料污染，目的是确定近岸、支流和海滩沉积环境中的分布模式和热点。微塑料集中在城市和工业区附近的近岸沉积物中。在亨伯湾和多伦多港，微塑料浓度始终大于每千克干沉积物500个颗粒。在埃托比科克溪中确定的最大颗粒浓度接近每公斤干沉积物28，000个颗粒。微塑料颗粒主要是纤维和碎片
Microplastics contamination of Lake Ontario sediments is investigated with the aim of identifying distribution patterns and hotspots in nearshore, tributary and beach depositional environments. Microplastics are concentrated in nearshore sediments in the vicinity of urban and industrial regions. In Humber Bay and Toronto Harbour microplastic concentrations were consistently >500 particles per kg dry sediment. Maximum concentrations of similar to 28,000 particles per kg dry sediment were determined in Etobicoke Creek. The microplastic particles were primarily fibres and fragments
