Abstract

This study aims to determine the levels of heavy metals (Cd) and (Pb) in shellfishes and mangroves at Bima bay. The results showed that bivalves and mangrove tissue were analyzed for heavy metal content in the form of lead (Pb), and Cadmium (Cd) using an Atomic Absorption Spectrophotometer. From tissue analysis, it indicates that the content of heavy metals lead (Pb) in 3 species of Shellfish which showed different results; Blood shells (Anadaragranosa) of 0.756 ppm, Hiatula shells (Hiatula chinensis) 1.59 ppm, and Shells (Siliqua winteriana) 1.171 ppm. Cadmium (Cd) metals in Shells are each found; Cockle shell (Anadara granosa) of 0.802 ppm, Hiatula shells (Hiatula chinensis) 0.334 ppm and Shells (Siliqua winteriana) 0.066 ppm. The content of lead metal (Pb) in the tissue of small mangrove leaves (Ryzophora apiculata) is 3.21 ppm and the mangrove leaves (Sonnerati aalba) is 3.74 ppm. For Cd levels in small mangrove leaves (Ryzophora apiculata) is 0.41 ppm while in mangrove leaves (Sonneratia alba) is 0.24 ppm

Highlights

Bima Bay is a bay that is used by the community for business activities such as fish ponds, fisheries, tourism and water transport activities
Sea water can be contaminated by various heavy metals such as mercury (Hg), lead (Pb), and cadmium (Cd) (Widowati, et al, 2008)
Data were collected by using manual method or Shells traps for various types of Shells such as Cockle shell (Anadara granosa), Shellfish (Siliqua winteriana), and Hiatula Shells (Hiatula chinensis) from the bivalvia class

Summary

Introduction

Bima Bay is a bay that is used by the community for business activities such as fish ponds, fisheries, tourism and water transport activities. Sea water can be contaminated by various heavy metals such as mercury (Hg), lead (Pb), and cadmium (Cd) (Widowati, et al, 2008). Many foods circulating in the community are contaminated with heavy metals such as lead (Pb), mercury Hg), arsenic (As) and cadmium (Cd). These metals come to human’s body through food, which can disrupt the nervous system, brain damage, and cancer (Agustina, 2010; Alina, et al, 2012; Rahmawati et al, 2015)
