Kandungan Logam Berat Pb, Cu, Dan Zn Pada Lokan (Geloina Erosa) Dan Siput Sedut (Cerithidea Obtusa) Di Pantai Dumai Barat Provinsi Riau

---

Industrial and shipping activities in West Dumai pose a risk of heavy metal contamination in coastal waters, potentially leading to bioaccumulation in organisms such as Geloina erosa and Cerithidea obtusa. This study aimed to determine the accumulation of lead (Pb), copper (Cu), and zinc (Zn) in the soft tissues of both species and to compare the concentrations between species and sampling stations. Samples were collected from two coastal stations in February 2025 and analyzed using Atomic Absorption Spectrophotometry (AAS). In G. erosa, the average concentrations were Pb 6.79 µg/g, Cu 6.13 µg/g, and Zn 8.36 µg/g, while in C. obtusa, they were Pb 7.09 µg/g, Cu 6.27 µg/g, and Zn 7.41 µg/g. Pb and Cu were higher at station 2, while Zn was highest in G. erosa at station 1 (9.12 µg/g) and in C. obtusa at station 2 (8.50 µg/g). The results showed significant differences in Cu and Zn levels in G. erosa (p=0.01; p=0.02), and in Zn levels in C. obtusa (p=0.01). These findings indicate that both species exhibit different accumulation patterns and respond uniquely to environmental conditions. Their capacity to reflect spatial differences in contamination supports their role as complementary bioindicators for monitoring heavy metal pollution in coastal ecosystems.
Keywords: Cerithidea obtusa, Geloina erosa, heavy metals, Western Dumai.
