Small plastic debris along the coast of Peru
AI summary Read the abstract
Small plastic debris including meso- and microplastics were surveyed along Peru's coastline, finding contamination at all sampled sites with significant variability by season and location. Higher concentrations were found near urban centers and river mouths, reflecting poor solid waste management and land-based inputs. The study provides the most comprehensive baseline data yet for plastic pollution along the Peruvian coast.
Peru suffers from poor solid waste and coastal management, as well as evidenced plastic pollution in various forms. However, studies on small plastic debris (i.e., meso- and microplastics) are still limited and inconclusive. Thus, the present study investigated the abundance, characteristics, seasonality and distribution of small plastic debris along the coast of Peru. The analysis revealed that the abundance of small plastic debris is predominantly driven by specific locations, where a source of contamination is present, rather than presenting seasonal patterns. Fishing and culinary activities are regarded as some of the most important sources of plastic pollution, as identified by the morphological and polymeric analysis of the samples. Additionally, heavy metals (e.g., Cu, Pb) were found on the surface of some mesoplastics at low concentrations. Here, we aimed to provide a baseline on the multiple factors involving small plastic debris on the Peruvian coast and preliminarily identify associated contaminants.

Microplastic fragments were found on four sandy beaches along the Peruvian coast, with the most contaminated beach having over 500 fragments per square meter. The findings document microplastic contamination in South American Pacific coastal environments where little prior data existed.
Microplastics on Three Sandy Beaches along the Central Coast of Peru
AI summary Read the abstract
Researchers surveyed three beaches on Peru's central coast and found microplastics at all sites, with the most heavily wastewater-polluted beach (Carpayo) showing the highest concentrations. Most small microplastics came from synthetic clothing and carpets, highlighting the link between wastewater discharge and coastal microplastic contamination.
