“…The health of aquatic biota is directly affected by the release of heavy metals into aquatic ecosystems, the release of heavy metals also causes bioconcentration in various plant and animal tissues. The food chain can lead to the absorption of toxic heavy metals into human body tissues [25][26][27][28][29][30][31].…”

Marine pollution, including heavy metals, is prevalent in Indonesian waters. Previous studies have found evidence of Pb, Cd, Hg, Al and Fe metal contamination in sediments and green mussels. This study used survey research. Heavy metal pollution is increasingly accumulating so that if it is not controlled it is feared that it will have an impact on public health, especially people who live around the coast. The research method was conducted using survey techniques. This study aims to estimate the burden of heavy metal pollution in the ocean. The research was conducted in 5 (five) areas of Indonesia, namely the East Coast of Sumatra, Winongo River in Yogyakarta, Semarang Bay, Bandengan Waters Kendal Central Java, and Ratai Bay Pasewaran Regency in areas with high human and heavy metal impacts. On average, the total results of heavy metal pollution exceed environmental quality standards. The situation in the 5 (five) research areas shows heavy metal pollution is very concerning because it is higher than the marine quality standard. The average concentrations of the measured elements in water were Al >Fe > Cu > Cd, with average values in descending order of 1.08 mg/L, 0.545 mg/L, 0.035 mg/L, and 0.005 mg/L, respectively. Environmental management should be implemented with the aim of reducing heavy metal pollution in Indonesian waters.

“…5). The highest peak height was achieved with 0.5 mol/L AB, because the formed metals-CCA complex was the most stable and widely spread on the HMDE surface (25,31). Therefore, 0.5 mol/L AB were used as SE in further experiments.…”

“…DPAdSV is very sensitive, and it can be used to analyze very small concentrations (µg/L or ng/L) of species in solutions (14,20). For heavy metals, the following voltammetric methods have previously been reported: AdSV, for Cu and Cd (21,22); DPAdSV, for Cr (23); FSV, for Cd (24); and AdSV-RSM, for Cu (25). However, the methods are still carried out individually, which consumes a lot of time and chemical reagents, when the metals are analyzed in nature.…”

The widespread use of HMDE for multi-ionic analysis is mainly explained by the following factors: excellent reproducibility, due to the electrode surface ease of renewal, for preventing hysteresis; wide Ec; ability to forming amalgams with many redox-active metal ions; and (sub)nanomolar detection limits, which have unique capabilities for multi-metal determination. In this research, selectivity and sensitivity for Pb, Cd and Zn simultaneous determination, by DPAdSV, using HMDE as WE and CCA as a ligand, were tested. This method is based on the deposition of CCA-metals on Hg electrodes. The instrumental and chemical parameters that could improve measurements were obtained under optimal conditions, including: CCA concentration (0.05 mmol/L), pH (7), Edep (-0.3 V) tdep (60 s), AB concentration (0.5 mol/L), scan rate (150 mV/s), pulse height (80 mV), Hg drop size (4 mm 2 ) and linearity (Ip vs concentration), which was in the range from 5 to 170, 5 to 140 and 5 to 190 M, for Pb, Cd and Zn, respectively). The LOD (S/N = 3) values were 0.05, 0.03 and 0.05 µg/L for Pb, Cd and Zn, respectively. The repeatability and intermediate precisions were tested as RSD of 0.44, 1.21 and 1.23% for Pb, Cd and Zn, respectively. The recovery values were 98, 99 and 101% for Pb, Cd and Zn, respectively. As result, the DPAdSV method with CCA ligands was successfully applied for heavy metals determination in the seawater of a former bauxite mining area.
