| dc.description.abstract | Microplastics are a relatively new sort of pollutant, but they have gained a lot of attention due to their
widespread and persistent presence in aquatic ecosystems. This study examined a UNESCO
Biosphere Reserve, HCMC's Can Gio Mangrove Forest. The estuaries have been chosen to evaluate
the accumulated microplastic content in surface water, column water, bed sediments, and two specific
species (oyster and mudskipper). Dong Dinh Estuary, Dong Hoa Estuary, Soai Rap Estuary, and Long
Hoa River are the selected estuaries. Its connected waterways receive waste from the city center and
from the Eastern Sea. The microplastic concentration in surface water (1.43±0.5 - 3.48±0.92 items/L),
column water (1.83±0.06 - 6.80 ± 4.10 items/L), bed sediment (46.67±23.09 - 290±81.85 items/kg),
oyster (Saccostrea) (1.5±0.96 - 1.8±0.38 items/individual), and mudskipper (Periophthalmodon
schlosseri) (0.2±0.35 - 0.52±0.36 items/individual). The dry season had higher levels of microplastic
abundance than the wet season. In comparison to urban rivers and other habitats, the level of
microplastic contamination in the estuary of Can Gio's mangrove forest was significantly lower. The
main shapes of microplastics are fibers (62.57%) and fragments (35.57%). FTIR identified the
composition as PP (45.45%) and PE (18.18%). The size distribution of microplastics is relatively
consistent across the ranges of 0.3 mm, 0.3-0.5 mm, 0.5-1 mm, and 1-5 mm. Microplastic pollution in
the Can Gio Estuary's surface water, column water, and sediment might help develop microplastic
reduction techniques. Microplastics in oysters and mudskippers are attentive. Our research highlights
microplastic contamination in river life. | en_US |
