| 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 insnail soft tissue was 26.33 ? 33.30 pieces/snail (F. martensi) and 11.50 ? 16.80 pieces/snail (P. canaliculata). The average size of microplastics found in P. canaliculata was a minimum of 1 ?m. 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. |
