[Pollution Characteristics of Microplastics in Migratory Bird Habitats Located Within Poyang Lake Wetlands].
Researchers found microplastics in surface water, sediment, and the droppings of migratory birds at a Chinese wetland lake, raising concerns about how birds can transport microplastics across long distances. The study suggests that migratory birds may be spreading plastic contamination between distant habitats.
Evaluation of Atmospheric Microplastic Presence at the UPC Villa Campus, Chorrillos District, Lima – Peru
Researchers evaluated atmospheric microplastic deposition at the UPC Villa Campus in Lima, Peru, finding measurable microplastic concentrations in air samples from this urban environment. The study contributes early regional data on airborne microplastic transport and deposition dynamics in South American urban settings.
Abundance and characterization of microplastic pollution in the wildlife reserve, Ramsar site, recreational areas, and national park in northern Jakarta and Kepulauan Seribu, Indonesia
This is the first study to measure microplastic pollution in sediments across protected areas near Jakarta, Indonesia, including a wildlife reserve, a Ramsar wetland site, and a marine national park. Microplastics were found at all locations, with higher concentrations closer to human activity and during the dry season. The results suggest that even designated conservation areas are not spared from microplastic contamination.
