Microplastics, as plastic particles smaller than 5 mm in size, are one of the emerging pollutants in aquatic ecosystems that have recently attracted the attention of global researchers to investigate the possible negative environmental consequences. In this study, 18 samples of Indian mackerel were purchased from fishermen in BandarAbbas, Minab, and Lengeh, and the abundance of microplastics in various tissues including dorsal muscle, liver, gills, and gut was determined. The results showed that the mean length and size of the fish specimens were 23.28 ±1.62 and 159.35 ± 31.06, respectively. The mean abundance of microplastics in muscle, liver, gill, and gut was 0.33 ± 0.59, 1.28 ± 1.84, 1.56 ± 1.61, and 1.22 ± 1.70 pa/ind, respectively. The maximum and the minimum number of microplastics were 8 and zero pa/ind, respectively. Fiber, fragment, and film shapes with 95%, 4%, and 1% frequency were the identified microplastics shapes in the samples, respectively. Different colors of black, red, blue, green, and other colors were identified for microplastics, of which black and red were the predominant colors of microplastics with a frequency of 50% and 13%, respectively. Microplasticity size analysis showed that more than 90% of them were less than 200 micrometers in size. A significant correlation (r = 0.49) was found only between fish size and the abundance of microplastics in the gut. Laboratory quality control showed the presence of microplastic contamination; Hence, muscle and liver tissue data had a high uncertainty, and therefore only gill and gut data were |
