“…Soil contamination with trace metals (TM), caused by industrial sewage and agricultural production, has become a worldwide problem [1]. The contamination of TM negatively affects the environment as well as decreases agricultural productivity and eventually causing a serious health risk to the consumers [2,3]. Through many natural processes, the contamination of soil is determined, especially by anthropogenic, lithogenic and pedogenic factors [4].…”

“…In contrast, TM (Al, Cr, Pb and Cd) and even those essential for growth and metabolism, may affect chickpea cultivars under Cd stress. The main objectives of the present experiment include: (1) to understand the effect of Cd on growth, and Cd accumulation of chickpea cultivars, (2) to understand differential responses of Cd stress among different chickpea cultivars and (3) to screen Cd-tolerant and non-tolerant chickpea cultivars for further studies.…”

Trace metals (TM) contamination is a severe problem in the environment and produced an adverse effect on the productivity of crops. Cadmium (Cd) is a TM ranked seven among the top 20 pollutants due to its high toxicity and solubility in water, taken up by the plants and affects their growth and metabolism. In this study, we evaluated the growth, Cd accumulation and tolerance capacities of three chickpea (Cicer arietinum L.) cultivars (NC234 (NC2), ICCV89310 (IC8) and ICCV89323-B (IC8-B)), subjected to two Cd concentrations (25 and 50 µM) in hydroponic culture. The toxicity of Cd reduced the plant height and fresh and dry biomass in all cultivars. The maximum reduction was observed at 50 µM of Cd. Compared with IC8-B, cultivars IC8 and NC2 exhibited better performance with high growth, biomass, root to shoot (R/S) ratio and water content under high Cd stress. To measure the accumulation of Cd in root and shoot, an inductively coupled plasma optical emission spectrometer (ICP-OES) was used. IC8 and NC2 had comparatively high Cd tolerance and accumulation ability (> 100 µg g−1 dry weight), with IC8 being more tolerant and accumulated higher Cd in shoot than NC2, while cultivar IC8-B was sensitive. Root accumulated more Cd than shoot in a dose-dependent manner. The bioconcentration factors (BCF) and bioaccumulation coefficients (BAC) were far higher than one (> 1) and increased with an increase in Cd concentrations, while the translocation factor (TF) was less than one (< 1), suggesting that all the three cultivars were unable to transfer Cd from the root to the shoot efficiently. Our results indicated that IC8 and NC2 proved to be resistant, while IC8-B showed sensitivity when exposed to high Cd stress (50 µM).

“…The uptake and distribution of heavy metals have an important influence on the accumulation of heavy metals in edible plant parts, which have been reported for many crop cultivars [39,40]. In the present study, heavy metals (iron) were absorbed by the plant roots, thus many researchers investigated the root uptake ability for clarifying the differences in heavy metals accumulation among cultivars [10,18]. The Cd and Pb concentrations of roots, shoots (leaves and stems) and fruits (DW) of hot pepper cultivars in control, T1, T2 and T3 treatments are illustrated in Tables 3 and 4.…”

Heavy metals (HMs) pollution in agricultural soil has become a worldwide environmental problem, because the HMs easily accumulate in soil and pose a great threat to the ecosystem, agro-system, and people's health [1-3]. Among HM-contaminated soils, cadmium (Cd) and lead (Pb) contamination in soils have been a worldwide environmental problem, especially in China [4], owing to exploitation and smelting of mines, deposition, sewage discharge, and the excessive use of fertilizers [5]. For example, Cd and Pb in the percentage

Environmental risks have a significant impact on the sustainability of subway station construction projects. This paper proposes an environmental risk assessment model based on the intuitionistic fuzzy analytic hierarchy process (IFAHP) and set pair analysis (SPA) to deal with the ambiguity and uncertainty in the assessment. An index system for environmental risk assessment is established based on a literature review and the rough set method. Subsequently, the IFAHP is used to calculate the indicator weights to describe the certainty, uncertainty, and hesitation degree of expert decisions in the weighting calculation by means of affiliation, nonaffiliation, and hesitation. Finally, SPA, which can deal with the randomness, uncertainty, and ambiguity of the indicators, is used to assess environmental risk. A case study of two typical stations (Lushan Avenue Station and Huilong Road West Station) of Metro Line 11 in Chengdu, China, is conducted. The case study results are consistent with field surveys. The evaluation results of the proposed model are more objective and reasonable than those of the traditional analytic hierarchy process, the entropy weight method, fuzzy comprehensive evaluation, grey correlation analysis, and technique for order of preference by similarity to an ideal solution (TOPSIS). The research results prove the scientific validity and superiority of the proposed model.
