The impact of cadmium-zinc interactions on phytobiochemical responses in Brassica napus cv. Hyola

The activity of antioxidant enzymes in response to cadmium-zinc interactions (Cd and Zn up to levels of 80 and 800 mg.kg-1, respectively) in Brassica napus cv. Hyola was studied using a factorial greenhouse experiment in a randomized complete block design with three replications. Results indicate that the content of hydrogen peroxide (H2O2) significantly increased with […]

Effects of arbuscular mycorrhizal fungi on wheat growth, physiology, nutrition and cadmium uptake under increasing cadmium stress

A pot culture experiment was carried out to study the alterations in growth, biochemical activities and cadmium (Cd) uptake by wheat (Triticum aestivum) inoculated with or without arbuscular mycorrhizal (AM) fungi in sterilized soil with addition of different Cd levels (0, 100, 300, 600 mg.kg_1). In Mycorrhizal (M) plants, root colonization rates were significantly lower […]

Effect of urban treated sewage sludge on concentration of lead and cadmium in parsley and its soil

Using sewage sludge, as fertilizer, in farmlands has been very prevalent. It is rich in plants nutrients but its heavy metals high concentration leads to contamination of soil, plants and food chain jeopardizing the human and animals’ health. This study aimed to examine the effect of using urban sewage sludge on concentration of lead and […]

Cadmium uptake and accumulation ability of Rosmarinus officinalis and its growth changes

To investigate the effect of cadmium and its accumulation rate on growth of Rosmarinus officinalis, this project was performed in Padina Research and Development greenhouse, Mashhad, Iran. Experiment was conducted by using clay pots in completely randomized design with 4 replications and 5 cadmium concentrations (0, 50, 100, 200 and 400 µM). Some traits such […]

Examining temperature effect on the adsorption and desorption of cadmium from soil surfaces and the best adsorption equation

In recent years, due to their simplicity, being relatively low price and also being reasonable and effective in the removal of heavy metal ions from wastewater, adsorption-based methods are of most interest. The objective of this research was studying adsorption isotherm of cadmium in the field’s soil of Amir- Kabir Sugarcane Crops And Industry Company. […]

Modeling of cadmium transport in the soil under sewage sludge application

The purpose of this study is to assess the possible contamination of the groundwater by Cd derived from sewage sludge through a plot study. For this purpose, four experimental plots, each size 2 by 10 m at Wastewater Treatment Plant-Shoush was prepared. A pvc drainage pipe was installed in one meter depth of each plot […]

Removal of strontium and cadmium from industrial wastewater using castor been and jojoba wastes

Four agricultural wastes: 1) castor bean leaves (CBL), 2) castor bean capsules (CBC), 3) jojoba leaves (JL), and 4) jojoba capsules (JC), were used as adsorbents for the adsorption of Strontium (Sr) from Abu Zaabal industrial wastewater. Three different dosages (0, 0.5, and 1g /100ml wastewater) were used for each at different contact times (1h., […]

Determination of mercury, cadmium, arsenic and lead in muscle and liver of Liza dussumieri from the Persian Gulf, Iran

The present study was carried out to investigate contamination of heavy metals Mercury, Cadmium, Arsenic and Lead in liver and muscle of Liza dussumieri from Persian Gulf, Iran, in 2012. Heavy metal levels in fish samples were analyzed by Perkin Elmer 4100 atomic absorption. This study concentration of heavy metals Hg, As, Cd and Pb […]

Phytoremediation of cadmium from effected soil using maize plant (Zea mays L.)

In present study, the soil and water were analyzed for cadmium metal. Its concentration in soil and water was 0.21 ml/kg and 0.001 mg/l respectively. For phytoextraction experiment pots were arranged in different groups such as Group A, B, C, D, E and F. To the soil of group A pots no metal was added […]

Theoretical risk assessment of lead, cadmium and arsenic mixture linked to consumption of garden products from Cotonou, Benin

Human-beings’ exposures, whether simultaneous or sequential, are not just to one chemical but to chemicals’ mixture. It is the case of coexposure to lead, cadmium and arsenic through the consumption of vegetables from Cotonou (Benin republic). This survey is a theoretical assessment of risk linked to mixture of these toxic based on assumption of contaminated […]
