'Lost' Ocean Nanoplastic Might Be Getting Trapped on Coasts. Plastic nanoparticles raise concern because of their potential impact on the environment. The term microplastic is used for small plastic particles of different origins, sizes and chemical composition. Inhalation of nanosized particles or ultrafine air pollution (PM 0.1) is associated with many health effects [41,42]. Within the last years, the focus of plastic pollution has been shifted from macro- to microplastics. It is amazing that global plastic contamination has been found in ice core samples from 50 years ago. This may occur through indoor activities as identified above, or through the drying of contaminated waterways or wastewater . One issue related to nanoplastic research is the difficulty encountered to identify microplastics of various sizes, . In the marine environment, plastics are usually broken down into smaller pieces by the sun, waves, wind and microbial .
