This study investigates the effects of polyvinyl chloride (PVC) microplastics on Telescopium telescopium, a gastropod from mangrove ecosystems. Although microplastics’ impact on ecosystems has been widely discussed, little is known about PVC effects on T. telescopium. We exposed specimens to control conditions and to PVC concentrations of 4 mg/L, 40 mg/L, and 400 mg/L for 4 and 28 days. Results show that the highest concentration led to significant PVC accumulation in the digestive tract, with an average of 68.5 µg per individual. Semi-quantitative histopathological analysis of the digestive gland revealed escalating damage: the histopathological index increased from 34.5 in controls to 66, 87.5, and 116.5 at 4, 40, and 400 mg/L, respectively. Oxidative stress biomarkers (SOD, CAT, GPx) increased markedly at 400 mg/L, reflecting heightened stress. Our findings underscore the physiological impact of PVC and indicate possible detoxification and adaptive responses in T. telescopium. © 2025 The Author(s).
