“…Monitoring the concentration of heavy metals in an aquatic environment is necessary for pollution control [21]. In addition, it is necessary to monitor water quality to maintain the stability of aquatic ecosystems [40]. Some efforts to control heavy metal pollution that can be done are by monitoring the discharge of waste into the waters regularly and checking ships to reduce oil spills into the waters.…”

The development of industry and residential areas around the waters of Banten Bay can increase the input of heavy metal waste and cause accumulation in aquatic biota, especially in mud crab (Scylla serrata). This study aims to determine the level of accumulation of heavy metals (Hg, Cd, Pb, and Cu) contained in mud crab meat in Bojonegara Coastal Waters, Banten Bay. Sampling of the mud crabs was carried out monthly for three months, from August to October 2020 in the waters. The research method consists of the calculation of Bioconcentration Factor (BCF), Maximum Weekly Intake (MWI), and Maximum Tolerable Intake (MTI). According to the analysis, content of heavy metals Hg, Cd, and Pb in mud crab was under the AAS sensitivity value used, which was <0.001 mg/kg, <0.005 mg/kg, <0.030 mg/kg, respectively, while for heavy metal Cu ranged from 4.44 to 13.52 mg/kg. The bioconcentration factor of the heavy metals Hg, Cd, and Pb in the water was classified as low accumulation, while heavy metal Cu in water was classified as medium to high accumulation. The safe limit for consumption of the mud crab meat taken in the waters was 12.94 kg meat/week (adults) and 3.88 kg meat/week (children).

“…hidup di daerah berlumpur atau perairan dangkal dekat hutan mangrove (Nanami dan Takegaki, 2005). Berdasarkan hasil penelitian sebelumnya, ikan Tembakul banyak dilaporkan sebagai bioindikator kualitas lingkungan (Santoso et al, 2020;Sangur et al, 2021), termasuk pencemaran logam berat. Ikan merupakan organisme penting dalam studi pencemaran logam berat, karena ikan bergerak bebas dan dan mengasimilasi logam berat (Kaur et al, 2018).…”

Mangrove vegetation has a wide range of distribution on the Indonesian coast, including Pemangkat, Sambas Regency, and West Kalimantan. Near this area, there are various activities, such as industrial, fishing, and shipping which are possible sources of heavy metal pollution. Water pollution caused by heavy metals is one of the serious problems. This condition can reduce water quality and has an impact on aquatic organisms. Monitoring of water quality needs to be done to reduce health problems and maintain the stability of aquatic ecosystems. Mudskipper (Boleophthalmus sp.) can be used as a bioindicator due to its ability to accumulate heavy metals from the environment, especially in mangrove areas. Heavy metal such as cadmium (Cd) is difficult to decompose and toxic to the environment and biota. This heavy metal pollution may originate from port and fisheries activities. The aim of this study was to determine the Cd content in the Mudskipper, waters, and sediment samples. Sampling was carried out at two stations. Analysis of the Cd content was done using Atomic Absorption Spectrophotometry (AAS). The result showed that concentrations of Cd in the waters and sediment samples were above the threshold. Meanwhile, the Cd level in Mudskipper flesh was still below the maximum limit. Keywords: heavy metal, cadmium (Cd), mudskipper, Pemangkat, West Kalimantan

“…No study, to our knowledge, has directly related changes in bioaccumulation rates in mangrove organisms, notwithstanding the notable influence of environmental factors like tidal variation, temperature, salinity, and concentrations of organic matter and nutrients, which are eventually affected by climate change (Guinot et al, 2012;Yam et al, 2020). Yet, the extent of metals uptake and bioaccumulation by organisms varies and potentially deleterious effects have been found in mangrove Crustaceans (crabs, shrimps), Molluscs (bivalves, mussels, oysters), and fishes, potentially affecting top consumers like birds and eventually humans (Silva et al, 2001;Ruelas-Inzunza and Páez-Osuna, 2008;De et al, 2010;Yam et al, 2020;Sangur et al, 2021).…”

This review discusses observed impacts from different climate change-driven pressures on mangrove's role in modulating trace metal transfer at the land-ocean interface. It contributes to the literature in a global context and shows mangroves as mitigators or providing positive feedback to metal mobilization. Most chalcophile metals2+ accumulate in mangrove soils associated with sulfides while high sedimentation rates avoid their oxidation. Exudation of oxygen by roots fixates Fe, which co-precipitates metals as oxyhydroxides in the rhizosphere. These two biogeochemical processes reduce trace metal availability to plants and their mobility within estuaries. However, climate change-driven pressures alter this geochemical equilibrium. Increasing atmospheric CO2 and temperature, and the intensity and frequency of extreme climatic events, have proved to affect mangrove functioning and cover, but no direct observation on the impact on metal biogeochemistry is presently available, whereas sea level rise and saline intrusion impacts on the fate of metals have already been observed. Sea level rise increases erosion, that dissociates deposited sulfides releasing metals to the water column. Released metals adsorb onto suspended particles and can re-deposit in the estuary or are exported to continental shelf sediments. Saline intrusion may oxidize deeper sediment layers releasing metals to porewaters. Part of the mobilized metals may remain in solution complexed with DOM and have their bioavailability increased, as shown by high bioaccumulation factors and biomagnification and high metal concentrations in the estuarine biota, which results in higher human exposure through fisheries consumption. Since erosion occurs preferentially at the sea border and higher sedimentation at the higher reaches of the estuary, triggering mangroves migration landward, spatial gradients are formed, and shall be taken into consideration when planning mitigation or adaptation strategies. These observations suggest disruption of traditional humans dwelling in mangrove dominated coastlines by increasing contamination of coastal fisheries, often the principal protein source for those groups and an important source of income. Further research into the environmental and socioeconomic impacts of climate change driven alterations to metal biogeochemical processes in mangroves as contaminant levels are expected to increase.
