“…Xincun Bay is a tourist attraction, as a result of which it had a lot of discarded packaging bags, which might be the main source of cellophane. Some studies have reported cellophane as the most common polymer type both in surface water and sediments (Wu et al, 2020). In our study, a relatively high abundance of polypropylene (PP; 28.7%) and polyethylene (PE; 12.3%) was detected.…”

Microplastics come directly or indirectly from human activities. The bay and coastal areas are constantly under pressure from human activities, including tourism, fishing, and aquaculture. Microplastic pollution is now recognized as a great threat to bay environments. In this study, we assessed microplastics in the Xincun Lagoon Bay, which had multiple human activities, to understand whether human activities could directly reflect the pollution level of microplastics. The results showed the dominant microplastics were small (100–500 μm, 45.2%) and transparent (57.0%), mainly consisting of fibers (95.7%), and cellophane (54.4%) was the dominant polymer. The color, type, and component indicated that wastes from aquaculture, laundry wastewater in the Tanka fishing raft area, and domestic wastes from tourism were the primary sources of microplastics in Xincun Bay. During the rainy season, microplastic abundances in surface water and surface sediment at the outer bay were found to be significantly higher (108.8 ± 37.1 item/L and 250.4 ± 92.0 item/kg, respectively) than those found at the inner bay (34.3 ± 12.9 item/L and 167.6 ± 71.7 item/kg, respectively), which presented a reverse trend in the dry season (p < .01). Although Xincun bay has a relatively closed environment and diverse human activities, concentrated rainfall and strong winds could cause microplastic abundance inside the bay during the rainy season to be lower than that outside the bay. Furthermore, the comparison of microplastic abundances in the areas with intensive human activities and non-human activity areas indicated that the intensity of human activities could not directly reflect the pollution of microplastics in the lagoon bay. It is also necessary to consider the geographical and seasonal characteristics in order to explain the pollution degree of microplastics in a bay.

“…Microplastic particles with a line shape are very misleading for fish, because the shape of the line is very similar to the food they will prey on (Masura et al, 2015), while the alleged source of microplastic with a line shape can come from the activities of fishermen catching fish with fishing gear used as, trawl nets, ropes, etc. (Wu et al, 2020). In this research, the abundance of microplastics in the form of lines in fish was higher than that of microplastics in the form of fragments.…”

“…Each abundance value were: Butini Fish (9.60 ± 6.947), Tilapia (7.80 ± 6.625), Snakehead Fish (5.87 ± 4.533), Climbing Perch (4.36 ± 3.264) and Flowerhorn (4.20 ± 2.783). In this research, the value of the abundance of microplastics in fish samples was higher than that of Wu et al (2020) which is 0.43 ± 0.69 items/individual. All fish samples consisting of five species are fish that are often consumed by the surrounding community.…”

“…All fish samples consisting of five species are fish that are often consumed by the surrounding community. So that fish of the same species that have a high potential to contain microplastics, will most likely be able to threaten human health as consumers (Wang et al, 2018;Wu et al, 2020).…”

“…The proportion of microplastic color in fish samples was dominated by blue. Several studies have also stated that in general, microplastics with blue particles are the most dominating and most commonly found in fish (Possatto et Wu et al, 2020). Blue microplastic particles can be found in paint compositions, in packaging compositions that are often used by the packaging industry and are generally sourced from anthropogenic activities (Lewis, 2004;Cauwenberghe et al, 2013;Dantas et al, 2020).…”

Microplastics (<5mm) are a serious threat, both to aquatic organisms and to humans directly. This is due to microplastics in waters can absorb various toxic substances, so as consuming aquatic organisms that have been contaminated with microplastics can endanger human health. So far, research on microplastics has generally been carried out in marine waters, but in this research it was conducted in fresh waters, especially on fish caught by fishermen which are often consumed by local communities in the waters of Towuti Lake, East Luwu, South Sulawesi. Sampling was obtained from fishermen, namely: 15 fish of butini (Glossogobius matanensis), 15 fish of tilapia (Oreochromis niloticus), 15 fish of snakehead (Channa striata), 11 fish of climbing perch (Anabas testudineus) and 15 fish of flowerhorn (Cichlasoma timaculatum). Identified, then measured body weight and total length. The gastrointestinal tract was dissected and taken then soaked in 20% KOH for 14 days, then observed microplastics with a stereo microscope. The result is an abundance of 4.20-9.60 items/individual, five color variants, namely: blue dominates, black, transparent, red and green, two form variants, namely: line dominates and fragments. The dominance of the blue items (34.09-67.52%) is thought to be due to the availability of a lot in general in the waters, while the dominance of the line shape (75.21-95.83%) is thought to be because the shape of the line resembles the shape of prey from fish such as phytoplankton and zooplankton.
