Impacts of macro - and microplastic on macrozoobenthos abundance in intertidal zone
Summary
This study assessed how macro- and microplastics affect the abundance of bottom-dwelling invertebrates in an intertidal zone, finding that plastic contamination is linked to reduced invertebrate diversity. The results highlight ecological impacts of plastic pollution in coastal ecosystems that provide food resources for humans.
Plastics pollution in coastal areas is one of the topics that have received more attention over the past few years. The intertidal zone is a waters area that is directly affected by contamination of plastic waste from land and sea. The purpose of this study was to analyze the types and abundance of plastic waste in the intertidal zone and its impact on macrozoobenthos abundance. This research was conducted at Pesisir Desa Jaring Halus in February-April 2017. Macrozoobenthos and macro - micro plastic were collected by using quadratic transect. Sediments were collected with a core, to a depth of 30 cm. Microplastic and macroplastic abundances were analyzed using separation of sediment density and hand sorting. The dominant micro plastic types were film (52.30%), fiber (24.88%), fragments (22.74%), followed by pellets (0.1%). The total number of microplastics were 326,33 items and macro plastic were 308 items. Macroplastic abundance is positively correlated with microplastic (0.765). The abundance of macrozoobenthos is negatively correlated with microplastic abundance (-0.368) and with macro plastic abundance (-0.633). The management strategies were suggested clean up marine debris, decrease plastic using and built up the station of debris processing.

Distribution characteristics and ecological risk assessment of microplastics in intertidal sediments near coastal water
Researchers analyzed microplastic contamination in intertidal sediments from coastal areas and assessed the ecological risks these particles pose. They found microplastics in all sampled locations, with fibers and fragments being the most common shapes, and polyethylene and polypropylene the dominant plastic types. The study's risk assessment indicates that microplastic pollution in these transitional zones between land and sea warrants greater environmental attention.
