Violin plots of the number of microplastics, (a) per g wet weight (WW) and (b) per individual, in Perna viridis sampled from the five sites reported in Fig. 1 (n = 10). A thicker part of the violin implies a higher frequency of that section of data. The median value is indicated by the red line, while the lower quartile and upper quartile are represented by the dashed black lines. The values of mean and standard deviation among the five sites are reported in Table 1. The values at sites indicated with different italic letters (x, y) were significantly different from each other, as revealed in the Kruskal-Wallis H test for the data (a) per unit WW (χ2(4) = 22.3, p < 0.05) and (b) per individual (χ2(4) = 21.8, p < 0.05), followed by Dunn’s multiple comparisons (p < 0.05).
