Abstract

Blood cockles are widely distributed in the coastal waters of West Lombok and are commonly consumed due to their high nutritional value. However, as filter-feeding organisms, cockles have the ability to bioaccumulate heavy metals, making them effective bioindicators of aquatic pollution. This study aimed to analyze the concentration of Cadmium (Cd) in blood cockles (Anadara granosa) and sediments collected from the coastal waters of Pantai Cemara, West Lombok. Sampling was conducted from January to September 2025 at three observation stations determined based on fishermen’s information regarding potential pollution sources. The results showed that Cd concentrations in cockles ranged from 0.039 to 0.047 mg/kg, with an average value of 0.044 mg/kg. Cd concentrations in sediments ranged from 0.013 to 0,019 mg/kg, also well below the sediment quality guideline value of 25 mg/kg.
