“…In this sample, the detected Cr(VI) content was 1.7 mg/kg. Hexavalent chromium quantification by isotope dilution mass spectrometry confirmed the great difficulties in determining accurately the Cr(VI) in the studied soil, as well as the non-negligible occurrence of this form in the soil [68].…”

For the assessment of the environmental and sanitary risks deriving from contamination of agricultural soils, it is crucial to identify and characterize the contaminants and study the soil chemical properties influencing their mobility and bioavailability. This information is essential for the selection of the best site remediation and securing strategy. The study site of this work is agricultural land of 6 ha in the province of Naples (Italy) subject to the past illegal burial of industrial wastes, principally from tanneries. With the aim of identifying the contaminants and assessing their mobility and bioavailability, the soil of the site was characterized for the main chemical and physical properties and for the concentration of potentially toxic elements and hydrocarbons. The readily and potentially bioavailable fractions of the main metal contaminants and their distribution in the soil geochemical fractions were determined by extraction in 1 M of NH4NO3, 0.05 M of ethylenediaminetetraacetic acid (EDTA) pH 7, and European Community Bureau of Reference (EU-BCR) sequential fractionation. Further, the speciation of heavy hydrocarbons and chromium was carried out. The agricultural soil was widely contaminated by chromium, zinc, and heavy hydrocarbons (up to 4487, 1846, and 1800 mg/kg, respectively). In some sub-areas, contaminations by cadmium, lead, and copper (up to 283, 417, and 1183 mg/kg, respectively) were also observed. The chromium was found to be scarcely mobile and bioavailable and was mainly associated with the oxidizable, residual, and reducible fractions of the soil (on average 56%, 25%, and 19% of the total, respectively). However, chromium speciation revealed the presence of a significant amount of highly toxic Cr(VI) (above the legal threshold of 2 mg/kg), despite the low oxidizing power of the soil. Zinc was more mobile and bioavailable than chromium and was mainly distributed among the acetic acid-extractable and reducible fractions of the soil (on average 28% and 47% of the total, respectively). Cadmium was found to be very mobile and bioavailable, and was mainly distributed in the acetic acid-extractable and reducible fractions of the soil (on average 40% and 45% of the total). The speciation of heavy hydrocarbons showed that they consist almost entirely of long-chain aliphatic hydrocarbons, considered not very toxic and immobile. These results suggest that the use of not-edible plant coverage might be the best securing and remediation action for the study site, with the potential to preserve the soil ecosystem services, contain the risk of soil erosion and particle dispersion, and phytoextract the bioavailable metals.

“…The method was applied to river water into which sewage was discharged and in which residents often swim. Although the title and abstract of an article by Caporale et al 97 suggest that a new analytical method has been developed for the quantification of Cr VI (in potentially contaminated soils from south Italy) by ID-HPLC-ICP-MS, it turns out that all the analytical methodology has been published previously. However, the article contains a useful critical discussion of the various procedures involved, particularly those concerned with extracting the soil samples.…”

“…Cr (VI) is a water soluble, bioavailable, and strong oxidant agent, that is correlated with the total Chromium content in the soil which can become highly contaminated (Weibel et al 2016;Caporale et al 2019). It has reported varied levels of Chromium as high as 350, 235, and 67(mgkg − 1 ) in farmland soil (Ertani et al 2017;Shahid et al 2017).…”

To assess food safety, the determination of the highly toxic Chromium (VI) concentration in vegetables is important. Accurate and efficient determination of Cr(VI) in agricultural products, due to complex matrices, still remains a challenge. In this study, we aimed to determine the Cr(VI) concentration in tomatoes grown in farmlands, which is potentially contaminated by Pb and Zn mines and factories. We used an alkaline extraction at 80°C, for 5min containing 50 mM EDTA and dispersive liquid liquid miroextraction (DLLME) by spectrophotometric assay. Method validation, including spiking recoveries, showed satisfying results for Cr(VI) determination. Tomatoes were collected from two case studies: A) farmland, where the average concentrations of total Cr in soils was 73,775.51 µg kg− 1 and B) farmland with an average Chromium 24083.68 µg kg− 1. The average concentrations of Cr(VI) and total Cr in tomatoes from the contaminated case study A were 341.037 ± 55.2037 µg kg− 1 and 2539.731 ± 268.3714, respectively, while the lowest average Cr(VI) value was found to be 98.93917 ± 51.13807 and total Cr was 1243.09 ± 562.4392 µg kg− 1, attributed to case study B. In site(A), The total Cr in soil correlated with the Cr in tomatoes (r = 0.548), while a relatively low correlation was found for Cr (VI) in tomatoes (r = 0.309). The evaluation of the potential human health risks associated with tomatoes indicated that inhabitant children are at considerable non-carcinogenic and carcinogenic risks.
