Study of Microplastic Contamination in 5 Dominant Fish Species of Chabahar Bay (Sistan and Baluchestan Province)
Original title: مطالعه آلودگی میکرو پلاستیکها در 5 گونه از ماهیان غالب خلیج چابهار (استان سیستان و بلوچستان)

This Persian-language study examined microplastic contamination in the gastrointestinal tracts of five dominant fish species in Chabahar Bay, Iran, finding plastic particles in multiple species and contributing to evidence of microplastic ingestion by marine fish in the Arabian Sea region.
The global demand for plastics is increasing due to it wide applications. About 60 to 80 percent of the waste of the marine environment belong to plastic class. There is a lack of information and research on the presence of plastic and micro-plastic contamination in aquatic animals, The present study, therefore examined the frequency, distribution, size, color and type of micro-plastic (MPS) in the gastrointestinal tract of 5 species (n =10) from the coasts of the Chabahar Bay, the Oman Sea in spring, 96. The total number of MPS found in the studied species varied and highest percentage of MPS in the gastrointestinal tract of the fish belonged to fiber (55%), fragments (26%) and pellets (18%). The results of the Fourier transform infrared spectroscopy (FT-IR) analysis from suspect samples were shown the microplastic samples were found. The most commonly detected polymers were polyethylene (PE), polyethylene terephthalate (PET) and nylon. The results showed that all fish sampled from Chabahar Bay contained MPS. Considering the importance of MPS pollution, it can be suggested by studying this contamination By monitoring the release of plastics on the shores of tourism and fishing in the Chabahar of bay, as a subject of future studies.

This Farsi-language study examined the environmental contamination caused by municipal waste disposal on a beach in southern Iran. Poorly managed waste disposal was found to be a major source of marine pollution, including plastics. The findings highlight inadequate waste management as a driver of coastal plastic contamination in developing regions.
