The accumulation of microplastics in marine organisms is an emerging concern. Due to trophic transfer, the
safety of seafood is under investigation in view of the potential negative effects of microplastics on human health.
In this study, market samples of Manila clams (Ruditapes philippinarum) from South Korea were segregated into
two groups of considerably different size (p < 0.05), namely small clams with shell length of 40.69 ± 3.97 mm,
and large clams of shell length 51.19 ± 2.86 mm. Comparative profiling of the number, size, shape, and polymer
type of microplastics were performed using μFTIR imaging and Nile red staining. Overall, μFTIR detected only
1559 microplastics while 1996 microplastics were counted based on staining from 61 Manila clams (30 small and
31 large), leading to an overestimation of 18 to 75 %. Comparable microplastics concentration, based on μFTIR,
were observed at 2.70 ± 1.66 MP/g or 15.64 ± 9.25 MP/individual for the small samples, and 3.65 ± 1.59 MP/...g
or 41.63 ± 16.90 MP/individual for the large ones (p > 0.05). Particle diameters of 20–100 μm was the most
dominant, accounting for 44.6 % and 46.5 % of all microplastics from the small and large groups, respectively.
Particles, with a circularity (resemblance to a circle) value between 0.6 and 1.0, were the most prevalent, fol-
lowed by fragments and fibers. At least 50 % of microplastics from the small and large samples were polystyrene,
making it the most abundant polymer type. Despite the substantial difference in the size of the animals, only a
weak to moderate correlation was observed between microplastics content and the physical attributes of the
clams such as shell length and weight, (soft) tissue weight, and total weight (Spearman's coefficient < 0.5). The
estimated intake of microplastics by the Korean population was 1232 MP/person/year via small clams, 1663 MP/
person/year via large clams, and 1489 MP/person/year via clams independent of size.
