| Abstract |
This study investigated microplastic accumulation in two fish species,
Barbonymus altus and Laides longibarbis, and two snail species,
Filopaludina martensi and Pomacea canaliculata, were the most dominant
species of fish and snails found and consumed in the Nam Pong River.
Twenty-four samples from each species were collected. The results showed
that the average amounts of microplastic accumulation in the gastrointestinal
(GI) tracts of fish was 25.42 ± 26.50 pieces/fish (B. altus) and 7.60 ± 17.70
pieces/ fish (L. longibarbis), and in snail soft tissue was 26. 33 ± 33. 30
pieces/snail (F. martensi) and 11.50 ± 16.80 pieces/snail (P. canaliculata).
The average size of microplastic found in P. canaliculata was a minimum of
1 μm. The most common polymer type of microplastic was high-density
polyethylene (HDPE) (26.00%), of which 55.47% was fragment-shaped and
22.29% was black. The accumulation of microplastics in the fish GI tract
was found to be significantly higher in B. altus than in L. longibarbis at
17.83 pieces/fish (95% CI: 4.72–30.95, p=0.008). One interpretation of this
observation is that the consumption of different types of fish may affect
microplastic acquisition. Nevertheless, in this study, microplastic
accumulation was not found in fish soft tissue. However, it cannot be
concluded that consumption of fish soft tissue is less risky than the
consumption of fish GI tracts. |
