“…The amount of lead absorbed by the plants irrigated with contaminated water was calculated using the bioconcentration factor (BCF) that several authors use. The relation is equal to BCF = Cplanta /Csuelo where Cplanta is equal to the concentration of the metal in the plant and Csuelo is the concentration of the metal in the soil where the plant grows [Castro et al 2018, Kicinska 2019]. The means of concentration of lead in the soil and pastures compared using the t test by means of the SPSS statistical package for data processing.…”

Agricultural soils that have been irrigated with the contaminated water from metallurgical mining activities for more than 70 years constitute an environmental problem as well as a concern for food security and human health. The presence of lead in the soil and cultivated pastures is highly dangerous, due to its toxicity, persistence and accumulation in plants and animals (cattle). This element enters the trophic chain of humans due to the intake of meat, milk and its derivatives. The concentration of lead was determined in the soil and the cultivated pastures with Lolium x hybridum Hausskn and Medicago sativa L. The soil and pastures samples collected from plots irrigated with river water contaminated with heavy metals at a depth of 0-20 cm. The content of Pb determined by the atomic absorption spectrophotometry. The results showed the lead concentrations in soil in the range of environmental quality standards for soils according to Peruvian regulations. In the soil with L. x hybridum and M. sativa the average content of lead was 57.17 ± 6.29 mg.kg -1 and 57.19 ± 8.99 mg.kg -1 ; in the above-ground tissues were 1.17 ± 0.69 mg.kg -1 and 1.62 ± 0.68 mg.kg -1 , respectively. In addition, no significant differences were observed in the Pb content in the soil and plant tissues. The bioconcentration factor (BCF) in the above-ground tissues of L. x hybridum and M. sativa was less than one and they were not significant. Therefore, irrigation with long-term contaminated water is not a concern for the farmers in the Mantaro Valley.

Heavy metals (HMs) can be accumulated along the food chain; their presence in food is a global concern for human health because some of them are toxic even at low concentrations. Unprocessed or minimally processed foods are good sources of different nutrients, so their safety and quality composition should be guaranteed in the most natural form that is obtained for human consumption. The objective of this scoping review (ScR) is to summarize the existing evidence about the presence of HM content (arsenic (As), lead (Pb), cadmium (Cd), mercury (Hg) and aluminum (Al)) in unprocessed or minimally processed foods for human consumption worldwide during the period of 2011–2020. As a second objective, we identified reported HM values in food with respect to Food and Agriculture Organization of the United Nations (FAO) and the World Health Organization (WHO) International Food Standards for Maximum Limits (MLs) for contaminants in food. This ScR was conducted in accordance with the Joanna Briggs Institute (JBI) methodology and PRISMA Extension for Scoping Reviews (PRISMA-ScR); advance searches were performed in PubMed, ScienceDirect and FAO AGRIS (Agricultural Science and Technology Information) databases by two reviewers who independently performed literature searches with specific eligibility criteria. We classified individual foods in food groups and subgroups according to the Global Individual Information Food Consumption Data Tool (FAO/WHO GIFT). We homologated all the reported HM units to parts per million (ppm) to determine the weighted mean HM concentration per country and food group/subgroup of the articles included. Then, we compared HM concentration findings with FAO/WHO MLs. Finally, we used a Geographic Information System (GIS) to present our findings. Using our search strategy, we included 152 articles. Asia was the continent with the highest number of publications (n = 79, 51.3%), with China being the country with the largest number of studies (n = 34). Fish and shellfish (n = 58), followed by vegetables (n = 39) and cereals (n = 38), were the food groups studied the most. Fish (n = 42), rice (n = 33) and leafy (n = 28) and fruiting vegetables (n = 29) were the most studied food subgroups. With respect to the HMs of interest, Cd was the most analyzed, followed by Pb, As, Hg and Al. Finally, we found that many of the HM concentrations reported exceeded the FAO/OMS MLs established for Cd, Pb and As globally in all food groups, mainly in vegetables, followed by the roots and tubers, and cereals food groups. Our study highlights the presence of HMs in the most natural forms of food around the world, in concentrations that, in fact, exceed the MLs, which affects food safety and could represent a human health risk. In countries with regulations on these topics, a monitoring system is recommended to evaluate and monitor compliance with national standards. For countries without a regulation system, it is recommended to adopt international guidelines, such as those of FAO, and implement a monitoring system that supervises national compliance. In both cases, the information must be disseminated to the population to create social awareness. This is especially important to protect the population from the consumption of internal production and for the international markets of the globalized world.
