Abstract
Microplastic waste in aquatic environments can lead to the mortality of large marine creatures, as it increases the risk of entanglement, strangulation, and starvation. Even though micro- and nano-plastics pose a hidden threat, researchers still know little about them. The food source is an essential factor in gut microbial diversity. A well-balanced intestinal microbiome impacts animal development and health. According to research, microplastics (MPs) like polyethylene (PE) and polystyrene (PS) affected the gut microbiota of Artemia sp., increasing their genetic diversity. Therefore, the present study examined the negative impacts of MPs within the gastrointestinal tract of Artemia sp., the primary protein source of fish. A comprehensive literature review showed that microplastic contamination and its additives impair environmental and aquatic health. The findings of this research show that MPs alter the gut microbiota of Artemia, which in turn affects fish and, ultimately, human health via a cascade of impacts.
