The Mediterranean Sea is particularly endangered by microplastics (MPs), polymers, and additives. These contaminants can be ingested fishes and, hence, translocate into tissues. We aimed to quantify MPs, polyethylene terephthalate (PET), polycarbonate (PC), bisphenol A (BPA), p-phthalic acid (PTA) in the edible muscles of swordfish (Xiphias gladius) bluefin tuna (Thunnus thynnus) caught Sea. MPs were extracted from characterized stereomicroscopy Raman microspectroscopy, while polymers (PET PC) additives (BPA PTA) identified LC-MS/MS. number ranged 140 270 no. kg−1 160 tuna. most frequent MP polymer was polypropylene (33%) (34.7%), abundant pigments PB115, PB116, PBr101/102. similar level plastic contamination revealed these two fish species with differences shapes, colors, MPs.

One of the main sources MPs contamination in fish farms is aquafeed. The present study investigated, for first time through a comparative approach, effects different-sized fluorescent included diet intended zebrafish (Danio rerio). A comparison based on developmental stage (larval vs. juvenile), exposure time, and dietary MPs' size concentration was performed. Four experimental diets were formulated, starting from control, by adding polymer (size range 1-5 µm) B 40-47 at two different concentrations (50 500 mg/kg). Zebrafish sampled 20 phase) 60 dpf (juvenile stage). Whole larvae, intestine, liver muscles juveniles collected analyses. Polymer absorbed intestinal level both larvae juveniles, while it evidenced hepatic muscular levels only juveniles. Hepatic accumulation caused an increase oxidative stress markers but same significantly reduced number able to reach muscle, representing efficient barrier against spread MPs. simply transited gut, causing abrasive effect goblet cell abundance stages.

Microplastic (MP) contamination in aquafeed poses a significant risk to fish health and safety. This study evaluated the effectiveness of microencapsulated natural antioxidant, astaxanthin (AX), mitigating adverse effects dietary MPs rainbow trout fry. The microcapsules were composed an organic wall matrix designed preserve AX while limiting MP absorption intestine. During 60-day feeding trial, fed diets containing amino formaldehyde polymer fluorescent microbeads (1-5 µm; 50 mg/kg), either alone or combination with AX. localization tissues was assessed via confocal microscopy, quantification performed following chemical tissue digestion. Fish welfare using histological molecular analyses. No on growth gut morphology observed across experimental groups. However, mainly translocated liver, where they induced oxidative stress, as evidenced by upregulation sod1, sod2, cat gene expression. inclusion significantly mitigated stress response, facilitated coagulation gut, reducing intestinal absorption. These findings highlight potential antioxidants counteract MP-induced reduce bioavailability aquaculture species, contributing improved product quality.

Despite plastic being an important convenience of contemporary living, microplastic pollution has recently gained international attention. From the deepest oceans to air we breathe, particles smaller than 5 mm are present everywhere. Microplastics have been discovered even in most isolated areas planet, such as arctic and mountainous regions. Their small size, lighter weight, bulk make them easily dispersible by wind. Even food water consume contain amounts plastic. They influence all levels biological organisation found impact on living world. Human blood, lung tissue, colon, placenta, stool, breast milk shown microplastics. But it is still unclear how they affect our health. There currently a dearth information main additives concern utilised industry, their destiny after microplastics released into environment, ensuing human health when combined with micro nanoplastics.
