The response of kenaf (Hibiscus cannabinus L.) to Zn/Cd contamination in soil was investigated using pot experiment. Plants were grown on soils containing increasing doses of two metals. Zn and Cd were applied alone or combined. Growth parameters as well as content of photosynthetic pigments, and photosynthetic performance were determined. Soil and plant tissue were analyzed by atomic absorptio...

Zinc (Zn) is an important micronutrient that can alleviate cadmium (Cd) toxicity to plants and limit Cd entry into the food chain. However, little is known about the Zn-Cd interactions in pasture plants. We characterized the effects of foliar Zn application and Cd uptake by ryegrass (Lolium rigidum L.) and clover (Trifolium subterraneum L.) grown on Cd-contaminated soils; all combinations of fo...

The toxicity of Pb and Cd+Pb was assessed on the Collembola F. candida in two cultivated soils (SV and AU) with low organic matter (OM) content and circumneutral to basic pH, and an acid forested soil (EPC) with high OM content. Collembola reproduction and growth as well as metal content in Collembola body, in soil, exchangeable fraction and soil solutions, pH and DOC were investigated. Pb and ...

development of industry in sistan and baluchestan (sb) province in iran, has increased the amount of cadmium (cd) in industrial wastewater, which is used as a secondary water supply in this area. the present study aimed to investigate the variation of cd concentration in soil column and cultivated cucumber plant in greenhouse under short-term simulated industrial wastewater irrigation. to simul...

A field study involving wheat production was extended in order to study the effects of biochar (BC) amendment in paddy soil that had long-term contamination of Cd. The BC was used as an amendment in Cdcontaminated soil for its special property. BC was amended at rates of 10 to 40 t ha -1 during the rice season before rice transplantation in 2009. BC amendments increased soil pH by 0.11 to 0.24 ...

This study aimed to explore the effects of Trichoderma reesei FS10-C on the phytoremediation of Cd-contaminated soil by the hyperaccumulator Sedum plumbizincicola and on soil fertility. The Cd tolerance of T. reesei FS10-C was characterized and then a pot experiment was conducted to investigate the growth and Cd uptake of S. plumbizincicola with the addition of inoculation agents in the presenc...

cadmium effects on soil microbial indices and on the interaction of arbuscular mycorrhiza fungi (amf) and as well on plant growth promoting rhizobacteria (pgpr) were investigated. the experiments were performed in the framework of a factorial design with levels of cadmium (0, 10, 30 and 100 mg kg-1 soil), and microbial inoculations (control, pgpr and amf) employing russian kanapweed as the expe...

Freeze-thaw cycles are predicted to increase in cold temperate regions. The potential influence of the interactions of freeze-thaw cycles and agrochemicals on the release of Cd into river water is unknown. In this study, the interactions of freeze-thaw cycles and chlorpyrifos (FC) on Cd mobility in soils were analysed. The spatial variability of soil Cd under long-term intensive tillage in a fr...
