“…Moderate to high Pb contamination was found in food resources (fish and oyster), collected from Meiliang Bay of Taihu Lake in China [ 7 ]. Pollution and contamination caused by Pb deposits have also been reported in Indonesia [ 8 ] and India [ 9 ]. Pb exposure, either through ingestion from contaminated foods or direct contact, can devastate human health [ 10 ].…”

Global pollution from toxic metal waste has resulted in increased research on toxic metal adsorption. A cellulose acetate–polyurethane (CA–PU) film adsorbent was successfully prepared in this research. The cellulose acetate–polyurethane film adsorbent was prepared with a polycondensation reaction between cellulose acetate and methylene diphenyl diisocyanate. The CA–PU bond formation was confirmed by functional group analysis obtained from Fourier transform infrared (FTIR) spectroscopy. The obtained film was characterized for improved tensile and thermal properties with the addition of methylene diphenyl diisocyanate (MDI). The adsorption ability of the obtained film was evaluated with laser-induced breakdown spectroscopy (LIBS). The best film adsorbent from the LIBS was selected and studied for adsorption isotherm. The FTIR analysis confirmed the formation of the CA–PU bond from the polycondensation between cellulose acetate and the methylene diphenyl diisocyanate. The result showed that the addition of methylene diphenyl diisocyanate (MDI) resulted in the urethane network’s growth. The characterization result showed an improvement in the morphology, thermal stability, and tensile strength of the film. The LIBS studies showed improvement in the adsorption of Pb2+ with CA–PU compared with the neat CA. The isotherm studies revealed that Pb2+ adsorption by cellulose acetate–polyurethane film adsorbent was heterogeneously dependent on the Freundlich isotherm model (R2 = 0.97044). Overall, the polycondensation method proposed by this study enhanced the Pb2+ removal, and was comparable to those reported in previous studies.

“…They discovered that the concentration of various non-earth sources resulted in an enrichment factor (EF) of Pb > 1. Armid et al [ 186 ] studied HM pollution in the surface sediments of Kendari Bay (Southeast Sulawesi), suggesting that the Kendari Bay surface sediment was regarded as an unpolluted area by HMs such as Cu and Zn). According to Asaf et al [ 187 ], the metal concentration in the coastal sections of Sangihe Island (Talengan Bay, Manalu, and Dagho Bay; North Sulawesi) was below the background value.…”

The ASEAN-5 countries (Malaysia, Indonesia, Thailand, Philippines, and Vietnam) of the Association of Southeast Asian Nations as a group is an ever-increasing major economy developmental hub in Asia besides having wealthy natural resources. However, heavy metal (HM) pollution in the region is of increasing environmental and public concern. This study aimed to review and compile the concentrations of Cu, Pb, and Zn in the aquatic sediments of the ASEAN-5 countries published in the literature from 1981 to February 2021. The mean values of Cu, Pb, and Zn in aquatic sediments were elevated and localized in high human activity sites and compared to the earth’s upper continental crust and reference values. Based on 176 reports from 113 publications, the ranges of concentrations (mg/kg dry weight) were 0.09–3080 for Cu, 0.37–4950 for Zn, and 0.07–2666 for Pb. The ecological risk (ER) values ranged from 0.02–1077 for Cu, 0.01–95.2 for Zn, and 0.02–784 for Pb. All reports (100%) showed the Zn ER values were categorized as being between ‘low potential ecological risk’ and ‘considerable potential ecological risk’. Almost all Cu ER values (97.7%) also showed similar ranges of the above two risk categories except for a few reports. The highest Cu level (3080 mg/kg dry weight) was reported from a mine-tailing spill in Marinduque Island of the Philippines with ‘very high ecological risk’. In addition, drainage sediments in the western part of Peninsular Malaysia were categorized as Cu ’high potential ecological risk’. Almost all reports (96%) showed Pb ER values categorized as between ‘low potential ecological risk’ and ‘moderate potential ecological risk’ except for a few reports. Six reports showed Pb ER values of ‘considerable potential ecological risk’, while one report from Semarang (Indonesia) showed Pb ER of ‘very high ecological risk’ (Pb level of 2666 mg/kg dry weight). For the ingestion and dermal contact pathways for sediments from the ASEAN-5 countries, all non-carcinogenic risk (NCR) values (HI values 1.0) for Cu, Pb, and Zn reflected no NCR. The ER and human health risk assessment of Cu, Pb, and Zn were compared in an integrative and accurate manner after we reassessed the HM data mentioned in the literature. The synthesis carried out in this review provided the basis for us to consider Cu, Pb, and Zn as being of localized elevated levels. This provided evidence for the ASEAN-5 group of countries to be considered as being a new socio-economic corridor. Beyond any reasonable doubt, an ever-increasing anthropogenic input of HMs is to be expected to a certain degree. We believe that this paper provides the most fundamental useful baseline data for the future management and sustainable development of the aquatic ecosystems in the region. Lastly, we claim that this review is currently the most up-to-date review on this topic in the literature.

“…Kendari Bay has been polluted [14], [15], transporting heavy metals both in estuaries and in coastal areas is influenced by various factors, including liquid waste, industrial waste, urban and agricultural waste, ports, atmospheric deposition, and combined inputs from rivers around Kendari bay. This study analyzes concentrations of Pb and Cr in Kendari Bay sea water at 0.0076 mg/L and 0.0052 mg/L.…”

Various studies have found the presence of heavy metal contamination in Kendari bay. Heavy metals can have implications for the health of residents living around Kendari Bay. Therefore, it is necessary to do seawater treatment to reduce the heavy metal content. The objective of this study is to reduce the heavy metal content of Plumbum (Pb) and Chromium (Cr) in seawater. The study employed quasi-experimental Nonequivalent Control Group Design. This study tested the decrease in the levels of heavy metals Plumbum (Pb) and Chromium (Cr) using the Atomic Absorption Spectrophotometry (AAS) method after flowing in the Montmorillonite medium. The results showed the highest decrease in Pb and Cr levels with variation in elevation of 80 cm using Montmorillonite and 100 minutes, each of them is 41% and 50%. The results of data analysis for Pb Level using the One Way ANOVA test obtained p-value values (0.000) <α (0.05), Cr levels obtained p-value value (0.000) <α (0.05). The concentration of seawater tested has decreased the strength of heavy metals after flowing through the medium of Montmorillonite. It should be noted that the decrease in salinity so that water can be used in fulfilling the daily needs of the community.
