These samples were then examined in the laboratory under a microscope to identify microplastics. Potential microplastics were singed with a hot needle and any changes were observed, as plastics react uniquely to heat compared to organic materials. Of the 116 samples that were examined, it was found that 77 samples contained at least one verified microplastic. Within these 77 samples, there were 192 microplastic pieces that were found in total. The most common microplastics found were blue fibers, and an analysis of the colors and types of microplastics was conducted.enmicroplasticmicroplastic pollutionScholarly Text or Essay
