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.
Assessment of microplastics in gastrointestinal tract of cattle egret (Bubulcus ibis) from a metropolitan city Lahore, Pakistan
Researchers examined the gastrointestinal tracts of cattle egrets from Lahore, Pakistan, and found significant levels of microplastics, with sheets and fibers being the most abundant types. Chemical analysis identified polyvinyl alcohol, polyisobutylene, and polyaramid as the main polymer compounds present. The findings indicate that even semi-aquatic bird species in urban environments are accumulating concerning levels of microplastic contamination.
