Widespread microplastic pollution in Peruvian mangrove sediments

Widespread microplastic pollution in Peruvian mangrove sediments and edible mangrove species. New study shows that the mangroves of Tumbes, Peru are extensively contaminated with microplastic pollution, and estimate that the local inhabitants are likely ingesting up to 430 plastic particles per year by consuming certain commercially-important species from this area. Previous field studies have demonstrated that microplastic debris can become trapped in aerial roots or the interior scrub zone of the mangrove. There is also an indication that microplastics can accumulate in the underlying sediments, and be ingested by or adhere to a wide range of aquatic organisms, including commercially-important species. The edible mangrove crab and black ark (a filter-feeding shellfish) are of highest commercial value in Tumbes mangroves and support the nutrition and socio-economic wellbeing of inhabitants in the region. Research has shown the presence of microplastics in the gills and digestive ...
