Sarpa salpa is a fish belonging to the Sparidae family and is usually found in local markets. Toxic metals such as aluminum (Al), cadmium (Cd), lead (Pb) and trace elements such as boron (B), barium (Ba), cobalt (Co), copper (Cu), chromium (Cr), iron (Fe), lithium (Li), manganese (Mn), molybdenum (Mo), nickel (Ni), strontium (Sr), vanadium (V) and zinc (Zn) are incorporated into fish tissues and remain there. The liver has the highest concentrations of all the analyzed toxic metals and almost all the analyzed trace elements. The consumption of 100 g/day of S. salpa muscle tissue does not pose a health risk. However, 100 g/day of liver consumption may pose a serious health risk due to the intake of Cd (572% of the tolerable weekly intake for adults with a body weight of 68.48 kg) and Pb (117% of the tolerable daily intake for adults weighing 68.48 kg). The consumption of liver of this species is not recommended due to its possible harmful effects on health.

Objective. Street-vended foods offer numerous advantages to food security; nevertheless, the safety of street food should be considered. This study has investigated the level of potential toxic metal (Pb, Cd, Hg, Sb, Mn, and Al) contamination among street-vended foods in Benin City and Umunede. Methods. Twenty street food samples were purchased from vendors at bus stops. Metals were analyzed with atomic absorption spectrophotometry. The methods developed by the US EPA were employed to evaluate the potential health risk of toxic metals. Results. The concentrations of the toxic metals in mg/kg were in the range of Pb (0.014–1.37), Cd (0.00–0.00017), Hg (0.00–0.00014), Sb (0.00–0.021), Mn (0.00–0.012), and Al (0.00–0.22). All the toxic metals except Pb were below permissible limit set by WHO, EU, and USEPA. The daily intake, hazard quotient, and hazard index of all toxic metals except for Pb in some street foods were below the tolerable daily intake and threshold value of 1, indicating an insignificant health risk. Total cancer risk was within the priority risk level of 1.0E-04 but higher than the acceptable risk level of 1E-06. Conclusion. Consumption of some of these street foods is of public health concern.

AbstractGeophagic clay consumption, which is an age-long cultural practice by humans and animals in many parts of the world, and particularly in Nigeria, may have long time health effects on the consumers. This is particularly so because of the relatively high concentration of harmful minerals and toxic elements. This study sought to determine the mineralogical and trace element compositions of geophagic clay in Uteh-Uzalla area, which is underlain by the Benin Formation of Oligocene to Miocene age, in order to evaluate the potential health risk associated with the consumption of the clay. Sixteen clay samples were collected from mine face profiles of an open pit, analysed for mineral and trace element compositions, using x-ray diffraction technique and ultra-trace inductively coupled plasma mass spectrometry (ICP-MS) methods, respectively. The mean mineral concentration in % includes kaolinite, quartz and smectite (64.88, 19.98, and 9.54), respectively, among other minerals. And the mean concentrations in mg/kg for Cu (15.0), Pb (14.4), Zn (30.9), Co (8.9), Mn (39.4) and Th (10.5) among other elements were found in the clay. From the trace elements results when compared with health risk indices by Agency for Toxic Substances and Diseases Registry (ATSDR): Minimum Risk Level, recommended daily intake and estimated daily intake, it was found that the elements are far above the daily oral intake requirement. Also, considering the relatively low pH (acidic) values that were exhibited by the clays, harmful minerals and elements contained in the clay may be bioavailable in the internal system among those who are frequently involved in the consumption of the clay.

The concentrations of trace elements in wines and health risk assessment via wine consumption were investigated in 315 wines. Samples were collected from eight major wine-producing regions in China. The concentrations of twelve trace elements were determined by inductively coupled plasma mass spectrometry (ICP-MS) and Duncan’s multiple range test was applied to analyze significant variations (p < 0.05) of trace elements in different regions. Based on a 60 kg adult drinker consuming 200 mL of wine per day, the estimated daily intake (EDI) of each element from wines was far below the provisional tolerable daily intake (PTDI). Health risk assessment indicated the ingestion influence of individual elements and combined elements through this Chinese wine daily intake did not constitute a health hazard to people. However, Cr and Mn were the potential contaminants of higher health risk in Chinese wines. The cumulative impact of wine consumption on trace elements intake in the daily diet of drinkers should not be ignored due to the presence of other intake pathways.

This study was carried out to establish health impacts of some trace elements (Al, As, Ba, Cr, Cu, Fe, Mn, Ni, Pb and Zn) in Asa-river, using Inductively Coupled Plasma-Mass Spectrometer technique for the chemical analysis. Laboratory results show that Al, Fe and Mn average concentrations are higher than prescribed limits unlike others. The Contamination Indexes reveal that the elements are heavily loaded in the water. The exposure dose in both adults and children ranges from 0.021 in As to 181 in Fe (in adults) and from 0.068 in As to 576 in Fe (in children). The average Hazard Quotient (HQ) values for adults and children are generally lower than one except Mn that has average value greater than one in both age groups. However, for children, individual HQ in Fe in some of the locations are >1. The Hazard Index (HI)for adults and children ranged from low to high. The average values of Chronic Daily Intake (CDI) are generally <1. However, in children, values for Fe in some locations are >1. The average Carcinogenic Risk (CR) of Cr and Pb computed for adults and children indicated that the values are greater than the risk limit of 10-6 and 10-4. This could result in potential health risk to the consumers. The sources of these trace elements are largely from various anthropogenic activities and slightly from weathering of rocks in the study area. It is recommended that adequate and well monitored precautions need to be taken to safeguard the health of the consumers especially the children with low immunity.

In Turabah province of Saudi Arabia, infant formula and children′s food products were investigated to determine the concentrations of essential trace elements, namely Mn, Ni, V and Si, and toxic trace elements, namely Al, Ba, Pb, Cd, and As, present in them. Their daily intake amounts were calculated and compared with provisional tolerable daily intake (PTDI), which was calculated based on the provisional tolerable weekly intake (PTWI), which was recommended by joint FAO/WHO. The results obtained were found to be below the PTDI levels. Some samples exhibited a large amount of Al. The PTWI of Si and V is not established; however, their concentrations were compared with those reported in other studies. In some samples, a high concentration of Si was observed. The method employed for evaluation was based on the limit of quantification (LOQ), limit of detection (LOD), and recovery percent of 92.3–101.6%. Accuracy and precision were employed for evaluating the results

Water pollution is a major threat to public health worldwide. The health risks of ingesting trace elements in drinking water were assessed in the provinces of Punjab and Khyber Pakhtunkhwa, Pakistan. Eight trace elements were measured in drinking water, using Inductively Coupled Plasma Mass Spectrometry (ICP-MS), and compared with permissible limits established by the World Health Organization (WHO) and the Pakistan Environmental Protection Agency (Pak EPA). In addition, health risk indicators such as the chronic daily intake (CDI) and the health risk index (HRI) were calculated. Our results showed that the concentrations of chromium (Cr), nickel (Ni), and manganese (Mn) were 2593, 1306, and 695 ng/g, respectively, in Lahore and Jhang, while the concentrations of arsenic (As) in Lahore, Vehari, Multan, and Jhang were 51, 50.4, 24, and 22 ng/g, respectively, which were higher than the permissible limits suggested by the WHO. The values of CDI were found to be in the order of Cr > Ni > Mn > Cu > As > Pb > Co > Cd. Similarly, the health risk index (HRI) values exceeded the safe limits (>1) in many cities (eg, Cr and Ni in Lahore and As in Vehari, Jhang, Lahore, and Multan). The aforementioned analysis shows that consumption of trace element-contaminated water poses an emerging health danger to the populations of these localities. Furthermore, inter-metal correlation and principal component analysis (PCA) showed that both anthropogenic and geologic activities were primary sources of drinking water contamination in the investigated areas.

Tolerable Weekly Intake

The main source of available forms of heavy metals (toxic metals) for the plant kingdom is anthropogenic, resulting from diverse activities such as metallurgic processing of ore, cement plants, uncontrolled discharge of sewage sludge, burning of fossil fuels and waste incineration plants, and leaded petrol. Agricultural chemicals (e.g. phosphate fertilizers containing cadmium) may also contribute to the contamination of cultivated plants. The main threats to human health from toxic metals are associated with exposure to lead, cadmium, mercury (organic forms, especially methylmercury) and arsenic (mineral form only), which have no known vital or beneficial effect on living organisms. As their toxicity often takes years to manifest and may go unsuspected, their toxicological risk is defined on the basis of the so-called Provisional Tolerable Weekly Intake (PTWI) values. Beside anthropogenic causes, the main factors that may lead to high levels of toxic metals in medicinal plants are their availability in the soil with soil pH as the most important parameter for uptake by the plant. Indeed, genetic features of certain plant species show a tendency to accumulate certain trace elements, especially cadmium (“cadmium collector”). A very recent revision draft of the monograph “Herbal drugs” (Ph. Eur., 1433) includes acceptance criteria for lead, cadmium and mercury. This proposal is discussed in detail, based on literature data dealing with terrestrial plants and seaweed. Additionally, the need for inclusion of tests for inorganic impurities in quality control specification is examined, based on a risk assessment. As the daily intake of food supplements is very similar to the one of herbal remedies, it would be advisable to take into account the same acceptance criteria. The specific situation has also been considered of exotic herbal remedies, particularly those of Asian origin, which have been repeatedly reported to contain toxic levels of heavy metals and/or arsenic resulting in heavy metal poisoning.

Consumption of cereals and cereal-based products represents 47% of the total food energy intake in Cape Verde. However, cereals also contribute to dietary exposure to metals that may pose a risk. Strengthening food security and providing nutritional information is a high-priority challenge for the Cape Verde government. In this study, toxic metal content (Cr, Ni, Sr, Al, Cd, and Pb) is determined in 126 samples of cereals and derivatives (rice, corn, wheat, corn flour, wheat flour, corn gofio) consumed in Cape Verde. Wheat flour samples stand out, with the highest Sr (1.60 mg/kg), Ni (0.25 mg/kg) and Cr (0.13 mg/kg) levels. While the consumption of 100 g/day of wheat would contribute to 13.2% of the tolerable daily intake (TDI) of Ni, a consumption of 100 g/day of wheat flour would contribute to 8.18% of the tolerable weekly intake (TWI) of Cd. Results show relevant Al levels (1.17–13.4 mg/kg), with the highest level observed in corn gofio. The mean Pb average content in cereals is 0.03–0.08 mg/kg, with the highest level observed in corn gofio. Al and Pb levels are lower in cereals without husks. Without being a health risk, the consumption of 100 g/day of wheat contributes to 17.5% of the European benchmark doses lower confidence limit (BMDL) of Pb for nephrotoxic effects; the consumption of 100 g/day of corn gofio provides an intake of 1.34 mg Al/day (13.7% of the TWI) and 8 µg Pb/day (20% of the BMDL for nephrotoxic effects). A strategy to minimize the dietary exposure of the Cape Verdean population to toxic metals from cereals should consider the continuous monitoring of imported cereals on arrival in Cape Verde, the assessment of the population's total diet exposure to toxic metals and educational campaigns.

ABSTRACT Cheeses are an important source of essential elements. Nevertheless, the level of some metals could pose a health risk. Therefore, the concentration of trace elements and toxic metals (Cr, Cu, Li, Ni, Sr, Pb, Cd, and Al) has been determined in artisanal cheeses from different geographical locations, and the intake of these metals from cheese consumption has been evaluated. The metal concentration was determined in a total of 90 cheese samples from different locations by using inductively coupled plasma atomic emission spectroscopy. The highest concentration of Al (35.1 ± 4.42 mg/kg, wet weight) was found in artisanal cheeses from Zamora (Spain), followed by Sr (6.85 ± 0.35 mg/kg, wet weight) in artisanal cheeses from Cadiz (Spain). A daily consumption of 23.2 g of cheese provides a significant dietary contribution for Al of 0.82% of its tolerable weekly intake of 1 mg/kg of body weight per week. Canary Islands cheeses have a higher metal content than the non-Canary cheese, which could be because of the volcanic characteristics of the island soils. The intake of toxic metals and trace elements poses no risk to the health of adults.
