“…Mercury and mercury salts affect internal organs (especially the intestinal mucosa and kidneys), while methylmercury is distributed throughout the body [ 28 ]. The contamination by mercury was reported in fish, sediments, hair, blood, and urine [ 29 ]. This metal induces tremors and sleep disturbances, irritability, excitability, excessive shyness, muscular spasms, loss of memory, depression, etc.…”

Heavy metals are chemical elements with a toxic effect on the human body. The expansion of industries has led to significant increasing levels of these constituents in the environment. Intensive agriculture can also lead to an increased concentration of heavy metals as a result of using different fertilizers and pesticides. Heavy metal accumulation in soil and plants represents a serious issue because of the potential risks to consumers. There are several methods available for the removal of these toxic components from different substrates (chemical precipitation, electrodialysis, coagulation and flocculation, photocatalytic removal, and adsorption-based processes), but most procedures are expensive and difficult to perform. Thus, more research is needed on the development of low-cost methods in foods. This work represents a review on the heavy metal presence in different food substrates (such as fruits and vegetables, milk and dairy products, meat and meat derivatives, oils, and alcoholic beverages) and provides an overview of the current situation worldwide, taking into account the fact that risks for human health are induced by the intensification of industry and the high degree of pollution. Considering that the toxicological quality of food affects its acceptability, this work provides valuable data regarding the actual situation on the proposed topic.

“…According to the statistics, non-ferrous metal smelting, mineral processing and other production activities are the main sources of most heavy metal pollution in wastewater which is characterized as strong acidity, complex composition, containing a large number of highly toxic heavy metal ions (Huang et al 2021), and therefore is hard to treat (Liang et al 2022). These heavy metals could accumulate in living organisms through the food chain, and thus have an indelible impact on human beings (Hill et al 2023, Marrugo-Madrid et al 2022.…”

Arsenic and cadmium are often co-existing in non-ferrous smelting wastewater, and the physicochemical properties such as surface charge, ionic morphology and redox activity are different between arsenic and cadmium, making the simultaneous removal of arsenic and cadmium challenging. In this study, an efficient and stable composite material of Fe modified Mg/Al-LDH was used for arsenic and cadmium co-adsorption experiments. The following conclusions were drawn: As (V) and Cd(II) were inserted into the interlayer region of the hydrotalcite, which As(V) was more favorably exchanged into the interlayer, as the inserted Cd(II) combined with the interlayer CO32− to generate a precipitate; The negatively charged As(V) served as a shield to balance the electric forces between Cd(II), and the coordinated deprotonated As(V) acted as an anionic bridge to enhance the adsorption of Cd(II). The structure-activity relationship between material structure and synchronous removal of arsenic and cadmium was clarified, and the mechanism of synchronous removal was revealed, which provided technical guidance for synchronous removal of arsenic and cadmium from non-ferrous metal smelting wastewater.

“…"For example, chronic exposure to arsenic has been found to provoke humungous diseases such as kidney and lung cancers, these include peripheral neuropathy, diabetes, ischemic heart disease, melanosis, keratosis and impaired liver and lung function, as well as dysfunction of the reproductive organs, neurological, cardiovascular and dermatological effects, and reproductive organ dysfunction" [9,10]. "For this reason, environmental studies of mining areas are important to protect the health of residents and the levels of arsenic contamination" [11,12]. "High concentrations of arsenic in air, sediments, soils, fishery products, and water due to mining activities have been reported in many countries including China, Côte d'Ivoire, and Morocco.…”

Arsenic contamination of sediments is a worldwide concern, both for the environment and for human health. However, few data are available on the state of arsenic pollution in sediments near artisanal and industrial gold mining areas in Côte d'Ivoire. The aim of this study is to assess the spatial distribution of arsenic and its ecological and human health risks in sediments around gold mining areas in northern Côte d'Ivoire. Sampling was carried out in artisanal and industrial mining areas in Korhogo and Tengrela, northern Côte d'Ivoire. Spatial differences were determined using analysis of variance. Pollution indices were studied using the contamination factor and the enrichment factor. Non-carcinogenic and carcinogenic risk indices were used to investigate human health risks. The study revealed total arsenic concentrations ranging from 1.64 ± 0.04 to 159.72 ± 51.91 µg/g. It found Arsenic concentrations in sediments varied considerably from station to station. The results of the contamination factor indicated that the sediments were weakly to very strongly contaminate with arsenic. Non-carcinogenic risk index values ranged from 1.83E-04 to 1.78E-02, indicating low adverse effects on the surrounding habitats. In addition, the results of the potential risk (CRt) for human health revealed the existence of significant carcinogenic risks from arsenic for residents in the vicinity of the Tongon mining area.
