The study aimed to detect the presence of microplastics in Perna viridis gathered from Jiabong, Samar and Tacloban City, Leyte. A total of twelve (12) mussels were collected. The samples were selected based on their similarities as to sizes and weights. Each group of mussels was placed in a digestive solution for two (2) days to dissolve most of the organic matter present from the samples. The resulting solution was filtered and dried using an oven for an hour at 50 °C. Dried filters were detected under a stereo microscope and were observed for the presence of microplastics. The microplastics observed were categorized by its shape and color.
The results showed more presence of microplastics in Perna viridis samples from Samar with an average of 1.12 ± 0.067 particles per gram as compared to Perna viridis samples from Leyte with an average of 0.18 ± 0.042 particles per gram. In terms of colors and shapes, most of the samples of Perna viridis from Samar were brown (37.93%) in color and had a filament (51.72%) shape. Similarly, most of the samples of Perna viridis from Leyte were black (42.86%) in color and had a filament (42.86%) shape.
With these results, the researchers concluded the presumptive presence of microplastics in Perna viridis from Jiabong, Samar and Tacloban City, Leyte. The researchers recommend further study into the effects of the presence of microplastics in mussels and other seafoods and its transfer to humans through consumption.
