This study is divided into two parts. The first part aims to verify the presence of microplastics in bivalves, namely and spp. using microscopy and Fourier transform infrared spectroscopy. The second part explores the knowledge, attitude and perception (KAP) of bivalve gleaners on microplastics and plastics. Results of the study confirmed the presence of microplastics in both bivalves, with polyamide fibers being the most common polymer found in the bivalves. The mean size of microplastics found in and spp. was 0.25 ± 0.05 mm and 0.33 ± 0.03 mm, respectively. Varying colors and shapes were also observed in both bivalves. Further, results of the KAP showed the lack of knowledge of the gleaners in terms of the basic information about microplastics. Nevertheless, they showed a positive attitude in terms of reducing plastic pollution and perceived coastal waters as important to them. The data on the two parts were used to compute for the estimate of the amount of microplastics that can be transferred to humans through consumption of bivalves, which was found to be 0.003 mg/day.

本研究分为两部分。第一部分旨在通过显微镜和傅里叶变换红外光谱法验证双壳贝类（即贻贝和蚶类）中微塑料的存在情况。第二部分探究双壳贝类采集者对微塑料和塑料的知识、态度及认知（KAP）。研究结果证实了两种双壳贝类中均存在微塑料，聚酰胺纤维是在双壳贝类中发现的最常见聚合物。在贻贝和蚶类中发现的微塑料平均尺寸分别为0.25±0.05毫米和0.33±0.03毫米。在两种双壳贝类中还观察到了不同的颜色和形状。此外，KAP结果显示采集者对微塑料的基本信息缺乏了解。然而，他们在减少塑料污染方面表现出积极态度，并认为沿海水域对他们很重要。利用两部分的数据计算了通过食用双壳贝类可转移至人体的微塑料量估计值，结果为0.003毫克/天。
