Abstract

Marine pollution by microplastics is becoming an increasingly worrying environmental issue, especially for filter feeder organisms such as blood clams (Anadara granosa), which are at high risk of bioaccumulating microplastic particles. This study aims to determine the accumulation rate of 20 µm and 150 µm polystyrene (PS) microplastics in blood clams in environments with different salinities, namely 20 ppt, 25 ppt, and 30 ppt. The methods used include exposure to microplastics in artificial seawater with variations in salinity and observation of microplastic accumulation in the mussel body using microscopic techniques and Anova statistical analysis. The results showed that the 150 µm microplastic accumulated more than the 20 µm size. The highest level of microplastic accumulation was found at 20 ppt salinity, which is thought to be due to osmotic stress that triggers increased filtration activity in blood clams. The three-way ANOVA test showed that variations in particle size and salinity had a significant effect on the level of microplastic accumulation (p < 0.05). These results were reinforced by the Tukey HSD test which also showed significant differences between size and salinity treatments.
