ClearContamination of Microplastics in the Gastropod Sulcospira sp. from Upstream of the Brantas River in Indonesia
This Indonesian study measured microplastic contamination in water and in the freshwater gastropod Sulcospira sp. collected from five sites along the upper Brantas River, finding microplastics present in both the water and the snails' bodies across all locations. Fragment-type plastics were most common, and land use near sampling sites appeared to influence contamination levels. Because these snails are part of local food webs — and in some regions are consumed by people — their contamination raises concerns about microplastic transfer up the food chain.
