Microplastic contamination on Cerithidea obtusa (Lamarck 1822) in Pangkal Babu Mangrove Forest Area, Tanjung Jabung Barat District, Jambi

Sedimentary and feeder depositing organisms such as Cerithidea obtusa are sensitive indicator species for various types of natural induction and anthropogenic disturbances that occur in mangrove areas, such as microplastic pollution. Microplastic contamination in the Pangkal Babu mangrove forest can be seen in sediment samples and Cerithidea obtusa. This study used sediment and snail samples taken at 4 different stations in the Pangkal Babu mangrove area. The types of microplastic found in the sample were fiber, film and fragments. The results showed that microplastic on snail reached 167 ± 16.01 particles/individual, with the highest average, namely microplastic film type 71.1 ± 14.57 particles/individual. Films also have a high average for sediments, namely 3.7 ± 0.28 particles/g. Based on the sampling station, station 1 has the highest microplastic average of 190 ± 37.74 particles/individual. The lowest microplastic average was found at station 3 in the amount of 153.3 ± 21.58 particles/individuals.
