Microplastic (MP) in seafood is a growing area of food safety. In the present study, MP contamination in the commercially important crabPortunus sanguinolentuswas assessed. A total of 300 crab specimens were collected from three principal fishing harbors of Gujarat. The collected specimens were analyzed for MPs isolation using a previously published protocol. The specimens were dissected, and organs such as the gut and gills were placed separately in the beaker. The organic tissues were digested using 10% KOH. After the digestion, flotation and filtration processes were carried out for the extraction of MPs. The physical (shape, size, and color) and chemical characterization of MPs were performed. The average abundance of MP was recorded as 0.67 ± 0.62 MPs/g. The pollution indices revealed very high contamination and fell under class IV (Jakhau) and V risk categories (Okha and Veraval). Microfibers were found dominantly. Blue and black-colored MPs with 1–2 mm sizes were recorded dominantly. Polyethylene, polyethylene tetraphene, polyurethane, polystyrene, and polypropylene were identified as polymer compositions of MPs. Concludingly, the present study gives an insight into the MP in an important crab speciesP. sanguinolentus, which can be useful to design further investigations on the toxicity of MPs in seafood.

Plastic pollution poses a pervasive threat to ecosystems worldwide, jeopardizing marine life, contaminating water sources, and perpetuating a global environmental crisis. Spatial and temporal distribution of beach debris was quantitatively assessed on three recreational beaches in Gujarat State, India. A total of six debris categories were recorded with a mean of 0.9 items/m² in number and 3.62 g/m² in weight. A total of Mean debris concentrations and weight per debris item did not vary significantly between study sites. Highest debris concentrations were observed in October 2021 at all sites. Around 90% was macro-debris (2.5–100 cm), with white and transparent colours most frequently encountered. Based on Clean Coast Index findings, all sites were categorized as "dirty". Plastic Abundance Index revealed that all sites had a very high abundance of plastics compared to other beach debris. Recreational activities on beaches, tourism, and extensive fishing can be the possible source of marine debris on Gujarat State. The findings of the current investigation is vital to understanding its pervasive environmental impact, encompassing threats to biodiversity, water quality, and ecosystems, while guiding effective policies to mitigate these repercussions on a global scale. It can be helpful to establish mitigation strategies urgently required to reduce marine debris pollution along the Gujarat Coast. It is recomanded to implement urgently needed mitigation strategies to diminish marine debris pollution along the Gujarat Coast.
