Abstract
The utilization of the coastal areas around Semarang Bay is very intensive, having the potential to cause pollution to coastal waters. Pb and Cd are 2 types of heavy metals that cause pollution in the waters of Semarang Bay. Both types of metals are found in various types of aquatic biota in the Semarang Bay, such as plankton, fish and green shellfish. This research was conducted to determine the concentration, bioconcentration (BCF), maximum acceptable concentration (MTI) of Pb and Cd in the waters and soft tissue of green mussels from the Semarang Bay. Green shells were collected from 2 locations in Semarang Bay, namely the waters around Tambak Mulyo and Bedono. The concentrations of Pb and Cd in water and soft tissue were analyzed by Atomic Absorption Spectrophotometry (AAS). Furthermore, the BCF and MTI values were determined. The results showed that the concentrations of Pb and Cd metals in seawater around the Mulyo Pond had exceeded the seawater quality standards for marine biota. The concentration of Pb in seawater around Tambak Mulyo was higher than in Bedono. The concentration of Cd around Tambak Mulyo was lower than in Bedono. Pb concentration in the soft tissue of green mussels has exceeded the limit of Pb concentration in fish meat and mollusks, according to the Indonesian National Standard. The bioconcentration factor of Cd in green mussels was higher than that of Pb. © 2021, BIOFLUX SRL. All rights reserved.
