The source provides the following methodology " From the available studies, the average percentage of litter that was plastic was 71% (±26%). Of this total plastic litter, the studies showed an average of 26% (±34%) of identifiable items made of plastic. To combine these studies in a robust manner and given that there was a large difference in the amount of litter collected in each study (445 to 120,600 litter items counted), we used weighted percentages based on the total number of items in each study. This resulted in the reported percentages for each item, which are out of all identifiable plastic litter items found in the freshwater environment."
