“…Groups with the same letter are not statistically significant different from each other (Post Hoc comparisons, p value < 0.05). lead to an increase in soil aggregation and compaction, which could have a negative impact in the plant growth (Koo et al, 2011). In this way it could be concluded that the dissolution of iron metallic ions from nanoparticles per se could not justify the phytotoxic effects of nZVIs observed in lettuce seeds.…”

“…Arsenic causes toxic effect in the plant by producing reactive oxygen species (ROS) which damage the cell membrane, hinder metabolism, reduce growth and alter the nutrient balance (Koo et al 2011;Gusman et al 2013b). In our study, the Mg concentration of the bean fruit and lettuce leaf decreased with higher As treatment.…”

“…In lettuce, the growth trend was opposite with the biomass of leaf increasing and root decreasing. Koo et al (2011) reported lettuce roots to be more sensitive to As exposure than the leaves. Lettuce grows well in contaminated soils, despite accumulating large amount of As, indicating higher tolerance to As (Gonzalez et al 2013).…”

Background: The uptake of arsenic by vegetables from soil irrigated with arsenic enriched groundwater poses a major health hazard. The edible portion of these vegetables transfer arsenic to the human beings. The uptake of arsenic was studied in bean (Phaseolus vulgaris L.) and lettuce (Lactuca sativa L.) in a controlled greenhouse pot culture with calcareous sandy soil as substrate. The plants were irrigated with water containing sodium arsenate at concentrations 0.1, 0.25 and 0.5 mg L − 1. The total arsenic concentration of the different plants parts was determined by ICP-MS, following microwave-assisted acid digestion. The change in plant biomass production and essential macroelements (Mg, P, K) and microelements concentration (Fe, Mn, Cu, Zn) was also studied. Results: The As concentration in the bean was in the order: root>stem>leaf>bean fruit and in lettuce: root>leaves. At the highest dose (0.5 mg L − 1) the As concentration in the bean fruit and lettuce leaves was 22.1 μg kg − 1 and 1207.5 μg kg − 1 DW, respectively. Increasing As concentration in the irrigation water resulted in decreased edible biomass production in bean, while in lettuce the edible biomass production increased. Neither plant exhibited any visible toxicity symptoms. No significant change was observed in the macro and microelements concentration. The total and the water-soluble arsenic in soil amounted to 3.5 mg kg − 1 and 0.023 mg kg − 1 , respectively. The transfer factor was found to increase with increase in the As treatment applied. The transfer factor range for bean from root to fruit was 0.003-0.005, and for lettuce from root to leaves was 0.14-0.24. Conclusion: Considering the FAO-WHO recommended maximum tolerable daily intake (MTDI) limit of 2.1 μg kg − 1 body weight, and the biomass production, both plants should not be cultivated at As treatment level higher than 0.1 mg L − 1. Keywords: Arsenic/irrigation water/ uptake/ transfer factor/calcareous sandy soil/vegetables contamination of the groundwater and soil is a major environmental toxicity issue, especially in Southeast Asia and in countries like China,

“…By using cultivation, it was confirmed that the root zone effect expressed in specific root length had a positive effect on SRA, URA, and DHA as well as DOC using stepwise multiple regression. In addition, the co-application of iron-based material also ameliorated the side effect of DOC derived from organic matter in soil [ 60 ]. Prior to the proposal of a general treatment plan, a scientific and quantitative evaluation of the impact factors and the integration of chemical, biological, and ecological assessments should be conducted in parallel.…”

Various types of organic and inorganic materials are widely examined and applied into the arsenic (As) contaminated soil to stabilize As bioavailability and to enhance soil quality as an amendment. This study deals with two types of amendments: biochar for organic amendment and acid mine drainage sludge (AMDS) for inorganic amendment. Each amendment was applied in two types of As contaminated soils: one showed low contaminated concentration and acid property and the other showed high contaminated concentration and alkali property. In order to comprehensively evaluate the effect of amendments on As contaminated soil, chemical (As bioavailability), biological phytotoxicity (Lactuca sativa), soil respiration activity, dehydrogenase activity, urease activity, ß-glucosidase activity, and acid/alkali phosphomonoesterase activity, an ecological (total bacterial cells and total metagenomics DNA at the phylum level) assessment was conducted. Both amendments increased soil pH and dissolved organic carbon (DOC), which changes the bioavailability of As. In reducing phytotoxicity to As, the AMDS was the most effective regardless of soil types. Although soil enzyme activity results were not consistent with amendments types and soil types, bacterial diversity was increased after amendment application in acid soil. In acid soil, the results of principal component analysis represented that AMDS contributes to improve soil quality through the reduction in As bioavailability and the correction of soil pH from acidic to neutral condition, despite the increases in DOC. However, soil DOC had a negative effect on As bioavailability, phytotoxicity and some enzyme activity in alkali soil. Taken together, it is necessary to comprehensively evaluate the interaction of chemical, biological, and ecological properties according to soil pH in the decision-making stages for the selection of appropriate soil restoration material.
