Abstract

Banten Bay is located in the north of Java Island and influenced by anthropogenic activities around the bay. Increasing population growth and rapid development of industrial and urban activities around the waters of the Banten Bay can lead to an increased input of pollutants in the form of heavy metal in the water body. This study aims to analyze the Pb and Hg levels that accumulate in mud crab (Scylla serrata) in Cengkok coastal waters, Banten Province. Samples of the mud crabs were taken in the waters for six months, from March to August 2019. Analysis of heavy metal concentrations was carried out using the Atomic Absorption Spectrophotometric (AAS) AA 7000 series Shimadzu. Heavy metal (Pb and Hg) in the mud crab in Banten Bay were below the specified quality standard. The bio-concentration factor of the mud crab was low (<100). Results of the calculation of the maximum limit of consumption of the mud crab meat (that accumulates heavy metals in the human body) were 3.5 kg of meat/week for adults and 0.9 kg of meat/week for children.Keywords: Crustacean, pollution, limit of consumption.

Highlights

Banten Bay has relatively shallow waters with substrates such as sandy mud and a coastline of 22 km with an area of ± 150 km2
Mud crab are benthic organisms that have the habit of immersing themselves in the mud
This study aims to analyze the levels of accumulated Pb and Hg and compared them based on the differences in the size of mud crab (Scylla Serrata) in Banten Bay

Summary

Introduction

Banten Bay has relatively shallow waters with substrates such as sandy mud and a coastline of 22 km with an area of ± 150 km. The bay is located in the north of Java Island and influenced by anthropogenic activities around the bay. Activities around Banten Bay include water transportation, industry, tourism, and aquaculture. Based on the status of the waters, the quality of Banten Bay waters is generally still good and suitable for aquatic organisms (Sugiarti et al, 2016). This result is in accordance with Tobing (2009) and Suwandana et al (2011) those conducted and concluded that the contents of nutrients and heavy metals in Banten Bay were still low.
