Agricultural intensification is associated with the use of great amounts of agrochemicals that may result in the accumulation of metals in soils, and –subsequently—agricultural products and food chain. Nowadays, this is a major concern for many Iranian agricultural products, necessitating scientific researches on the issue. Therefore, the present study has been conducted to evaluate the level o...

The topsoil around Beijing metropolis, China, is experiencing impacts of rapid urbanization, intensive farming, and extensive industrial emissions. We analyzed the concentrations of Cu, Ni, Pb, Zn, Cd, and Cr from 87 topsoil samples in the pre-rainy season and 115 samples in the post-rainy season. These samples were attributed to nine land use types: forest, grass, shrub, orchard, wheat, cotton...

Plant extraction is a thorough remediation method to remove heavy metals from soil. Chelating agents can enhance the effect of soil by plants. In this study, low molecular weight organic acids (LMWOAs), such as citric acid (CA), tartaric (TA) and polyaspartate (PASP), were added farmland contaminated with Cd Pb combined corn absorption Cadmium (Cd) Plumbum (Pb). The effects LMWOAs on growth yie...

Cadmium (Cd) has attained top priority among all the toxic trace elements, and it easily accumulates in human body through various pathways. The current pot study was focused on impacts of foliar spray zinc oxide nanoparticles (ZnO NPs) (0, 50, 75, 100 mg·L−1), alone or combined with soil-applied bamboo biochar (1.0% w/w), maize growth Cd Zn accumulations grains under Cd-contaminated soil. resu...

Organic amendments have been proposed as a means of remediation for Cd-contaminated soils. However, understanding the inhibitory effects of organic materials on metal immobilization requires further research. In this study colza cake, a typical organic amendment material, was investigated in order to elucidate the ability of this material to reduce toxicity of Cd-contaminated soil. Available co...

we examined cadmium (0.1 mmol/l) toxicity and effect of different calcium concentrations (0.1, 1.0, and 10.0 mmol/l) on the growth of organs (root, mesocotyl and coleoptile) of 4-day-old maize seedlings in hydroponic cultures. The influence of both metals on distribution of cadmium, calcium, potassium and sodium in the organs of maize seedlings was also studied. Calcium at a concentration of 1....

This study was carried out to determine the effects of cadmium (Cd) (0 and 2 mg kg-1 soil) and salt stress (NaCl 0 and 3000 mg kg-1 soil) on shoot dry weights and shoot Cd, sodium (Na) and potassium (K) concentrations of salt-tolerant (Maverik) and salt-sensitive (RX-9292) hybrid maize varieties. Plants were grown under controlled greenhouse conditions for 19 days. Shoot dry matter productions ...

In order to investigate the heavy metal contamination of soil-crop in mining-intensive areas Gejiu stannary Yunnan Province and its risk human health, single-factor index method Nemero comprehensive were used evaluate metals (Cd As) soil areas, health evaluation model was study brought by residents through consumption maize, wheat broad beans. The results showed that mean values total As Cd are...
