Kandungan Logam Berat Pb, Cu, Dan Zn Pada Lokan (Geloina Erosa) Dan Siput Sed…

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 stat…
