“…The THQ for adults and children was also below 1.00. A study by Praveena and Lin [89], revealed that the THQ values calculated for Cu in marine fish collected from Port Dickson (west coast of Peninsular Malaysia) were also less than one, indicating that there were no Cu adverse effects via fish consumption.…”

Potentially toxic metals (PTMs) in edible marine fish have been widely reported from at least 15 different regions or countries in the literature. This evidently demonstrates the importance of monitoring the PTMs in fish fillets from a human health risk (HHR) point of view. This study aims to assess the HHR of Cu and Zn in 19 species of marine fish from popular marine fish loading sites at Setiu in Terengganu, on the east coast of Peninsular Malaysia, collected between August 2016 and February 2017. With overall ranges of concentrations (mg/kg dry weight) of Cu (1.50–7.83), and Zn (24.1–80.5), the 19 species of marine fishes from Setiu are good sources of these essential elements because they are below the maximum permissible limits set by seafood safety guidelines. The target hazard quotient values of Cu and Zn were lower than one, indicating non-carcinogenic risks of Cu and Zn in fish consumption. It was also found that the calculated values of the estimated weekly intake were below the established provisional tolerable weekly intake of Cu and Zn. It can be concluded that the consumption of fish from Setiu would not pose adverse effects from the PTMs to consumers. Nonetheless, continuous monitoring is necessary to ensure the safety of consumers who rely heavily on marine fish in Setiu coastal waters.

“…Children and adults had THQs below 1.00. Praveena and Lin [89] Cu THQ levels were below 1 in all 40 commercial fish species (Figure 3) and selected fish species' skin portions (Figure 4), indicating low non-carcinogenic risk and safe human intake. The absence of Cu health risks was also established.…”

“…Children and adults had THQs below 1.00. Praveena and Lin [89] observed that marine fishes from Port Dickson (west coast of Peninsular Malaysia) had Cu THQ values below 1, suggesting no Cu adverse effects from eating. According to Table 1 and Figure 5, Cu EWI ranged from 0.10 to 27.3 µg/kg BW/we with Arius arius and Tylosurus crocodilus having the lowest and greatest concentratio Figures 5 and 6 show reduced EWI in 40 fish species' dorsal muscles and 10 fish spec skin parts compared to the Cu (3500 µg/kg BW/week) determined PTWI.…”

The presence of potentially harmful metals in commercially available saltwater fish has been extensively documented in scientific literature. This has demonstrated the significance of monitoring the crucial copper (Cu) levels in fish fillets from a perspective focused on human health risks (HHR). This study aimed to evaluate the human health risk (HHR) associated with the presence of Cu in 40 different species of commercial marine fish purchased from Malaysia. The fish samples were gathered from various sources from April to May 2023. The 40 species of commercial marine fish had concentrations of Cu (0.72–82.3 mg/kg dry weight) that fell below acceptable levels defined by seafood safety recommendations. Therefore, these fish are considered good sources of the essential element. The target hazard quotient values for Cu were below 1, suggesting that the hazards of Cu from fish eating are non-carcinogenic. Furthermore, it was discovered that the computed values for the predicted weekly consumption were lower than the defined provisional tolerated weekly intake of Cu. Consuming fish purchased from Malaysia is unlikely to harm consumers’ necessary copper intake. However, it is crucial to consistently monitor the safety of consumers who heavily depend on commercially caught marine fish from Malaysia. This monitoring is an essential aspect of implementing environmental, social, and governance (ESG) practices, which industries are concerned about and report on annually.

“…Subsequently, heavy metals that are released to the aquatic environment can bioaccumulate along the aquatic food chain (11), with prolonged and continuous consumption of contaminated aquatic organisms posing a significant health risk to the community (12). In fact, even in small amounts, heavy metals can either in the body or in a metabolically available form that affects essential biochemical processes (13).…”

Introduction: Car wash premises consume large amounts of water that can later end up in the public irrigation system. This production of wastewater, which contains heavy metals, are both detrimental to the marine environment and unsustainable. Methods: In this study, sugarcane bagasse (SB), coconut pulp (CP) and sawdust (SD) were investigated to determine their potential usage as low-cost, heavy metals adsorbents. The morphology of these adsorbents was characterized using Spectrometry Electron Microscope (SEM), while presence of heavy metals constituents on selected adsorbents was analysed using Atomic Absorption Spectrometry (AAS). Adsorbents Adsorption efficiencies were calculated to determine the best adsorbent. Results: CP with a more porous structure promotes a larger surface area, compared to SB and SD. Adsorption was optimized at pH 4 in room temperature for 4 hours, with adsorbents particle between 0.5 mm and 2.5 mm in size. SD was the best adsorbent for Iron (Fe) and Copper (Cu) removal with 95.6% and 86.5% removal efficiencies. Meanwhile, CP was the best adsorbent for Zinc (Zn) and Manganese (Mn), with percentage removal of 78.9% and 24.8% respectively. Conclusion: The findings of this study can be used by relevant agencies for a better policy regarding on wastewater management and support the concept of turning waste to useful products.
