“…The first [100] consisted in the quantification of As, Cd, Cu, Ni, Pb and Zn in globe artichoke. The second one [101] determined Cd, Cu, Ni, Pb and Zn in globe artichoke leaves and soybean seeds, and the third work quantified [102] Cd and Pb in apples, tomatoes, carrots, and lettuce. All of these methods based on UAE were low-cost, employed diluted acidic media such as HNO 3 or HCl and were in agreement with Green Analytical Chemistry (GAC) principles.…”

“…Water and soil contamination by potentially toxic elements (PTE) is a global concern because it threatens food security and human health ( Bui et al, 2016 , da Silva Júnior et al, 2019 , Deng et al, 2021 , Pereira et al, 2021 ). Soil contamination comes mainly from industrial and urban waste, excessive use of fertilizers and pesticides, and air pollution ( Ahmed et al, 2019 ); as well as, soil erosion, lithogenesis, weathering, and geological processes ( Alfaro et al, 2019 ).…”

The contamination of water, air and soil with potentially toxic elements (PTE) compromises the supply of contaminant free food. Vegetables grown in contaminated soils can absorb and accumulate PTE at concentrations that are toxic to human health. In this context, the human risk associated with the intake of artichokes grown in soils irrigated with PTE contaminated water was assessed. 120 samples of surface soil and artichoke heads were collected and the concentrations of Cu, Fe, Pb, Zn and As were determined. The results showed that the concentrations of Cu, Fe and Zn in soil did not exceed the standards of the Ministry of Environment of Peru, but they did exceed those of Pb (125.45 mg kg −1 ) and As (28.70 mg kg −1 ). The decreasing order of mean PTE concentration in artichoke heads was Fe > Zn > Cu > Pb > As, exceeding the permissible levels of FAO/WHO CODEX Alimentarius. However, the concentrations of As comply with the maximum limits of inorganic contaminants in vegetables (0.3 mg kg −1 ) established in the MERCOSUR regulations. The non-carcinogenic and carcinogenic risk of Pb and As indicated that the ingestion of artichoke heads does not represent a health risk.

“…MAE has been used since the 1980s in trace element analysis, but alternatives that improve these methods by performing them under milder conditions have become increasingly necessary. More recently, the use of ultrasound-mediated extractions has gained interest, and there are already numerous publications demonstrating that they are efficient [9][10][11][12][13], but the use of ozone-mediated extraction has been little explored.…”

A green analytical method for the determination of Cu and Zn in rice samples was developed. This method was based on an ozone-assisted extraction (OAE) in diluted acid media. A novel closed system was designed for this purpose that allowed four simultaneous sample treatments being safe for the laboratory environment. The method consisted in 0.5 g of the sample, 15 minutes of ozonation, and 3 minutes of centrifugation. The obtained supernatant was ready for Cu and Zn determinations by flame atomic absorption spectrometry. Detection limits were 0.20 and 0.08 mg kg−1 for Cu and Zn, respectively, with a precision (RSD) better than 5% for both elements. A certified reference material of rice flour was analyzed for trueness evaluation, and the mean recoveries (%) were 100.4 (Cu) and 95.9 (Zn). Several commercial rice samples were analyzed using this method, and the results were compared with those obtained using traditional microwave-assisted digestion (MAE). Both methods yielded comparable results. Cu and Zn levels were in accordance with reported values in other regions. The OAE resulted to be simple and economical and with results equivalent with those obtained using traditional sample preparation procedures as MAE with the advantage of being in good agreement with the principles of green analytical chemistry.
