Soil contamination with heavy metals, including Cd and Pb, is of serious concern. The aim of this study was to investigate the efficiency of Atriplex verucifera, Salicornia europaea and Chenopodium album for simultaneous remediation of soil exchangeable sodium percentage and Cd and Pb contamination in two soils with different properties. Two soils, including a saline-sodic-calcareous (S1) and c...
ceruloplasmin (cp) is a human plasma protein with multiple physiological functions including ferroxidase and oxidase activities. deficiency or inhibition of the enzyme may lead to some abnormalities, including iron deposition in several tissues and causes various pathological conditions in the body. direct interaction of cadmium (cd), a widespread, highly toxic environmental pollutant, with hum...
To investigate the effects of Cd and Cd-Sodium nitroproside (SNP) on growth and physiological parameters of Melia azedarach, this experiment was done in a completely randomized design in three replicates and arranged as factorial. Results showed the amounts of Cd and proline in the root of the plant significantly increased as Cd concentration in soil increased. Length and weight of roots decrea...
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...
The present study is focused on the importance of SNP, a NO donor, as Cd stress modulator on seedlings of cabbage. The exogenously applied Cd induced stress in cabbage seedlings to explore the protective role of SNP. 21-day-old seedlings were grown in Hoagland solution and Cd at 0.5 and 0.7 mM concentration with and without SNP. The biophysical and biochemical parameters were analyzed. Cd exhib...
This research was done in hydroponic environment in greenhouse at 3 stages (vegetative, flowering and full product) in 5 concentrations of Cd (0.1, 0.3, 0.9, 2.7, and 10 mm) for investigating physiological and biological effects. This study revealed that the increase of Cd concentration in understudy treatments causes the 49% reduction of sugar solution in 10 mm treatment. On the other hand, th...
Influence of Cadmium Toxicity on Rice Genotypes as Affected by Zinc, Sulfur and Nitrogen Fertilizers
Cadmium (Cd) is among the most widespread and toxic heavy metal in several part of the world. Its toxicity in soil is becoming a severe threat to living organism worldwide. It is one of the main pollutants in paddy fields near industrial areas and highly toxic to plant growth and development of the plants. Cd can be easily taken up by plants and enter the food chain. Therefore, precautionary me...
Pollution of the environment by heavy metals, especially soil pollution with cadmium (Cd), is one of the most important environmental problems. Also, salinization of soils due to a decrease in irrigation water quality reduces plants growth. To investigate the effect of sugarcane bagasse biochars and salinity on Cd available and Cd fractions in a contaminated soil (15 mg kg-1 Cd), an experimenta...
cadmium (cd) concentration in soil solution and its bioavailability is controlled by sorption-desorption reactions. the objective of this research was to compare cd adsorption behavior in six calcareous and four acid soils. soil samples were equilibrated with 0.01 m ca(no3)2 containing 25 to 3200 mg cd l−1. results showed that the tendency for adsorption was high at low cd concentrations (0-400...
