“…Overall, a decreasing trend in Pb concentrations has been observed in Israeli marine waters since 1996 (NAP, 2015). Turkish waters have also seen decreasing trends of Pb compared to previous years, with mean concentrations ranging between 0.16 and 0.91 mg/kg w.w. (Korkmaz et al., 2019), at least two orders of magnitude higher than our values (Table 2). Of the four HM assessed in this study, it appears that Pb is of the least concern regarding its accumulation in the local marine biota.…”

“…These high Cd concentrations were explained by a significant presence of industrial and agricultural activities in most of the studied sites (Copat et al., 2012). However, Cd concentrations in the marine environment appear to show an overall decreasing trend, with reported decreasing concentrations in specimens caught in Turkey, and it was concluded that Cd poses little threat to the health of the human population (Korkmaz et al., 2019). In Israel, marine Cd input has been associated with industrial emission via river discharge (NAP, 2015; Shefer et al., 2015).…”

Seafood is capable of bioaccumulating heavy metals (HM), making it a potentially major dietary source of HM for humans. Presently, little data exists on seafood from the eastern‐most boundary of the Mediterranean Sea. This study aims to provide exposure insight of the Israeli population to HM through the consumption of locally caught seafood by assessing the levels of arsenic, mercury, cadmium, and lead in raw tissues of seafood. A wide survey of local fisheries was conducted providing 296 samples from 11 different species, including seven fish, two crustacean, and two cephalopod species. Total arsenic, cadmium, and lead were analyzed by graphite‐furnace atomic absorption. Total mercury was measured by cold‐vapor mercury analyzer. Arsenic speciation was performed by anion chromatography‐inductively coupled plasma sector field mass spectrometry. Results suggested that the total arsenic concentrations were significantly higher in crustaceans and cephalopods than fish. Arsenic speciation revealed two samples that exceed 1 mg/kg of inorganic arsenic, whereas methylated arsenic was below the detection limit. Elevated mercury levels were detected in the commercial benthic species Mullus barbatus (red mullet), cadmium was detected in one‐third of the samples, and lead detected in eight samples. Comparing the results to health guidelines, 99.4% of seafood tested in this study abide with acceptable levels of heavy metals in seafood, as defined by both Israeli and European Union guidelines.

“…Furthermore, depending on the sex/maturity stage of totoaba, consumption of this fish’s muscle may provide approximately 70% Cu, 60% Zn and 100% Fe of the recommended DRI. Both RDA and RfD are comparable to the values obtained in muscle of several fish species from the Mediterranean Sea and the Gulf de California ( Bilandžić et al, 2014 ; Korkmaz et al, 2019 ; Zamora-Arellano et al, 2018 ). It is calculated that 130 g of totoaba muscle can provide approximately 20% of the daily tolerable dose of Cd.…”

“…The Environmental Protection Agency (EPA) recommends for Cu 0.40 mg kg −1 day −1 ; Cd 0.001 mg kg −1 day −1 ; Zn 0.30 mg kg −1 day −1 ; and Fe 0.7 mg kg −1 day −1 ( United States Environmental Protection Agency, 2020 ). The EPA has not established an RfD for Pb because a “safe” exposure limit for Pb toxicity is still uncertain ( EFSA, 2010 ; Korkmaz et al, 2019 ).…”

Background The fish Totoaba macdonaldi is endemic to the Upper Gulf of California. Its migratory movements involve sites with high levels of trace elements in the environment that can accumulate in tissues. In this study, lead (Pb), copper (Cu), cadmium (Cd), zinc (Zn) and iron (Fe) concentrations in male and female totoaba liver and muscle were quantified at various sexual maturity stages along the species’ geographic distribution. Methods Generalized linear models were used to explore associations between trace element concentrations and season of the year, sex/maturity stage, and total fish length. Results No detectable Pb concentrations were recorded in liver or muscle; Cu, Cd, Zn and Fe contents in totoaba liver and muscle were typical of fish inhabiting areas with no contamination issues and are within international maximum permissible levels for human consumption. Variations in the content of Cd, Cu, Zn and Fe in liver of totoaba seem to be more related to the feeding and reproductive physiology of this species than as result of environmental exposure. Results suggest that consumption of totoaba muscle does not pose a public health risk. Furthermore, depending on the sex/maturity stage of totoaba, this fish’s muscle may provide approximately 70% Cu, 60% Zn and 100% Fe of the recommended dietary reference intake.

“…These metals are assumed to be ubiquitous toxicants, and their deadliness is influenced by many factors, for instance, the amounts of heavy metal doses, types of elements and exposure route [ 12 , 13 , 14 ]. Heavy metals can be transported into the human body via many sources, for instance, water, air, skin and food, and can become more lethal in the human body when they are not completely digested and stored in the muscle [ 15 , 16 ]. They may damage various vital human organs such as gastrointestinal, kidneys, bones, endocrine glands and central nervous system [ 17 , 18 , 19 , 20 ].…”

Removal of Chromium(III) and Cadmium(II) Heavy Metal Ions from Aqueous Solutions Using Treated Date Seeds: An Eco-Friendly Method

et al. 2021

The aim of the research was to prepare low-cost adsorbents, including raw date pits and chemically treated date pits, and to apply these materials to investigate the adsorption behavior of Cr(III) and Cd(II) ions from wastewater. The prepared materials were characterized using SEM, FT-IR and BET surface analysis techniques for investigating the surface morphology, particle size, pore size and surface functionalities of the materials. A series of adsorption processes was conducted in a batch system and optimized by investigating various parameters such as solution pH, contact time, initial metal concentrations and adsorbent dosage. The optimum pH for achieving maximum adsorption capacity was found to be approximately 7.8. The determination of metal ions was conducted using atomic adsorption spectrometry. The experimental results were fitted using isotherm Langmuir and Freundlich equations, and maximum monolayer adsorption capacities for Cr(III) and Cd(II) at 323 K were 1428.5 and 1302.0 mg/g (treated majdool date pits adsorbent) and 1228.5 and 1182.0 mg/g (treated sagai date pits adsorbent), respectively. It was found that the adsorption capacity of H2O2-treated date pits was higher than that of untreated DP. Recovery studies showed maximal metal elution with 0.1 M HCl for all the adsorbents. An 83.3–88.2% and 81.8–86.8% drop in Cr(III) and Cd(II) adsorption, respectively, were found after the five regeneration cycles. The results showed that the Langmuir model gave slightly better results than the Freundlich model for the untreated and treated date pits. Hence, the results demonstrated that the prepared materials could be a low-cost and eco-friendly choice for the remediation of Cr(III) and Cd(II) contaminants from an aqueous solution.
