“…In any case, in this study, all vegetable fruits always do not exceed the suggested thresholds recommended by the European Food Safety Authority regarding the dietary exposure, where the average value is 4.6 mg kg −1 for tomato, 12.0 mg kg −1 for pepper and 4.9 mg kg −1 for zucchini, respectively [39]. Although the As translocated in the vegetable fruits was similar in both systems, these results induce the assumption that the alternative cropping system based on hairy vetch cultivation under no-tillage conditions could cause a stratification of inorganic As due to its immobilization in hairy vetch biomass and soil organic matter, thus resulting in a positive effect in reducing the As accumulation in various vegetable crop tissues (Figure 2), in agreement with other studies [2,40]. In fact, the hairy vetch treatments in combination with no-tillage practice resulted to improve SOM content due to the addition of plant residues from cover crop that probably promoted the adsorption of As in the soil resulting unavailable for plant uptake.…”

“…Similarly, in the sweet pepper crop, the hairy vetch mulching system reduced the As accumulation of 37%, 31% and 73% in root, stem and leaf respectively, compared to the conventional one, while in the zucchini crop the reduction of As accumulation was 64%, 31% and 16% in root, stem and leaf respectively. According to Stazi et al [2], crop plants grown in rich As soil accumulate it in all plant organs, even if the As accumulation tended to be higher in roots, stems and leaves compared to the fruits. In fact, averaged among all vegetable crops, the As content in fruit represent only the 4% of the total As accumulated by the whole plant (Table 4).…”

“…310 m a.s.l.). The experimental area is located in central Italy characterized by soil of volcanic origin with high As concentrations related to the deep-rising fluids of the active geothermal systems [2]. The soil of the experimental site is classified as a Typic Xerofluvent [27], with 63% sand, 22% silt, 15% clay in the 0-25 cm depth of soil horizon and considered as sand-loam based on USDA classification of the particle size distribution analysis.…”

“…Arsenic naturally occurs in the earth surface (on average 1.5-2.0 mg kg −1 ). However, as observed in many areas around the world the As concentration in soil greatly varied among the areas reaching high concentration (above 50.0 mg kg −1 ) in soil and water [2]. Consequently, As could be easily assimilated by plants and animals that are used for human consumption [3].…”

“…Several researches reported that As is one of the few metal elements that raises concerns of higher concentration in food chain [4,5]. It is well known that high As concentration in the soil produce plants with increased As content, even if the distribution of As in the plants greatly varies among the different plant organs generally showing lower values in seeds and fruits compared to leaves, stems and roots [2]. Low concentration of As in plant tissue does not determine specific metabolic reactions, while its high concentrations could interfere with metabolic processes inhibiting the plant growth and sometimes leading to plant death [6].…”

Agricultural practices greatly influence the bioavailability of heavy metals. Arsenic (As) is a heavy metal identified as a concern due to its potential impact on human health. Two-year field experiments were performed to evaluate the effect of cropping system on As accumulation in tomato, sweet pepper and zucchini. The treatments were: (i) conventional system based on common practices of the area; and (ii) alternative systems based on cultivation of hairy vetch (Vicia villosa Roth.) in no-tillage before vegetable crops. Randomized block design with three replications was adopted. Soil and plant samples (fruits, leaves, stems and roots) were collected at crop harvesting. Plant samples were weighed and analyzed to evaluate As content. Soil chemical analyses were performed to evaluate the total organic carbon and nitrogen content. The As accumulation observed in plant samples of tomato, sweet pepper and zucchini resulted always low in the alternative system, except in fruits where As accumulation was similar between the systems. The increase of soil organic matter observed in alternative system probably caused a reduction of As accumulation into crop tissues. Therefore, hairy vetch cultivation in no-tillage could be a suitable strategy to reduce the As uptake of vegetable crops in geogenic contaminated soils.

Background Arsenic (As) may represent a risk for crop yield quality and human health since it may accumulate in the edible plant organs with the potential of leading to acute or chronic toxic effects in varied segments of the population. Management of soil fertility through compost has proven to be a valuable practice for increasing and maintaining soil organic matter, with nutritional benefits for crops. This work aimed to evaluate Swiss chard yield and the change in the bioavailability, bioaccumulation, and partitioning of As in the response of the use of compost or conventional mineral fertilization in an open‐field trial conducted in a volcanic area in central Italy characterized by the natural contamination of As in soil. Results Compost treatment led to a short‐term increase trend in soil organic carbon, total nitrogen, and available phosphorus in a significant way. In the compost‐amended plots, the mitigation of the As uptake was detected in leaves, which are the edible part of Swiss chard. The As bioaccumulation factor in leaves of Swiss chard and the translocation factor for leaves/roots were also decreased using compost. Conclusion Fertilization by compost can improve soil fertility, sustain Swiss chard production, and mitigate As accumulation in leaves of this crop grown in a naturally As‐contaminated soil. © 2022 The Authors.

In this study we simulate the irrigation of tomato plants with As contaminated water (from 0 to 3.2 mg L -1 ) and investigate the effect of the application of silicon nanoparticle (Si NPs) in form of silicon dioxide (0, 250 and 1000 mg L -1 ) on As uptake and stress. Arsenics concentrations were determined in substrate and plant tissue at three different stratums. Phytotoxicity, As accumulation and translocation, photosynthetic pigments and antioxidant activity of enzymatic and non-enzymatic compounds were also determined. Irrigation of tomato plants with As contaminated water caused As substrate enrichment and As bioaccumulation (roots > leaves > steam) showing that the higher the concentration in irrigation water, the farther the contaminant owed and translocated through the different tomato stratums. Phytotoxicity was observed at low concentrations of As, while tomato yield increases increased at high concentrations.Application of Si NPs decreases As translocation, tomato yield, and root biomass. Increased production of photosynthetic pigments and improved enzymatic activity (CAT and APX) suggested tomato plant adaptation at high As concentrations in the presence of Si NPs. Our results reveal likely impacts of As and nanoparticles on tomato production in places where As in groundwater is common and might represent a risk.
