摘要

海洋中的微塑料可能会干扰海洋生物的健康,包括绿贻贝(Perna viridis)。这是由于贻贝器官中的微塑料积聚,如鳃、肝胰腺和性腺。因此,组织改变是生态风险分析和其他生态毒理学研究活动的良好指标。绿贻贝,壳长4.1至5.0厘米,采自印度尼西亚Pangkep Regency (Pangkajene Islands) Mandalle水域。绿贻贝暴露于浓度分别为0.05 (A)、0.5 (B)和5 (C) g/L的微塑料环境中7天。结果表明,接触绿贻贝的微塑料浓度越高,贻贝体内的微塑料积累量在测试浓度范围内越高。微塑料浓度的增加增加了鳃、肝胰脏和性腺的组织改变水平,其中最敏感的器官是肝胰脏。总之,本研究证实了贻贝器官的组织学检测可作为生态毒理学研究的生物标志物。

Histological Alteration of Green Mussel Perna viridis Organs Exposed to Microplastics
Microplastic in the oceans might interfere with the health of marine organisms, including the green mussels (Perna viridis). This is due to microplastic accumulation in mussels organs, such as gills, hepatopancreas, and gonads. Therefore, tissue alteration is a good indicator for ecological risk analysis and other ecotoxicological study activities. Green mussels with shells 4.1 to 5.0 cm in length were collected from Mandalle waters, Pangkep Regency (Pangkajene Islands), Indonesia. Green mussels were exposed for seven days to microplastic with concentrations of 0.05 (A), 0.5 (B), and 5 (C) g/L. The results showed that the higher the concentration of microplastics exposed to the green mussel, the higher the accumulation of microplastics in the body of the mussel, within the tested concentrations. The increased concentration of microplastics increased the level of tissue alteration in the gills, hepatopancreas, and gonads, with the most sensitive organ being the hepatopancreas. Overall, the study confirmed that the histological assay of mussel organs could be used as a biomarker in ecotoxicological studies.
