a greenhouse experiment was conducted to investigate the effects of mycorrhial fungus (glomus mosseae) on cadmium (cd) toxicity in pepper (capsicum annuum l. cv. zhongjiao 105) plants. half of plants were inoculated with arbuscular mycorrhizal fungi (amf). cd was supplied in the form of cadmium chloride at 0.0, 0.1 and 0.5 mm through irrigation water in the soil. mycorrhizal colonization was hi...

Phenols exert a great influence on the dynamic process of Cd in the soil-plant interface. We investigated the influence of phenols on the biogeochemical behavior of cadmium in the rhizosphere of Avicennia marina (Forsk) Vierh. All combinations of four levels of cadmium (0, 1, 2 and 4 mg/kg DW) and two levels of phenol (0 and 15 mg/kg DW) were included in the experimental design. We found that p...

abstract nowadays, environmental pollution by heavy metals is one of the most serious threats of the world which needs effective remediation actions. the aim of this study was to investigate the potential use of atriplex [atriplex verucifera], salicornia [salicornia europaea] and chenopodium album in simultaneous uptake and accumulation of na and cd or pb in two calcareous soils with different ...

Cadmium and cadmium compounds are contaminants of the environment, food, and drinking water and are important constituents of cigarette smoke. Cd exposure has also been associated with airborne particulate CdO and with Cd-containing quantum dots in medical therapy. Adverse cadmium effects reported in the literature have stimulated during recent years an ongoing discussion to better elucidate ca...

Cadmium is a potent inhibitor of hepatic microsomal drug biotransformation in the rat. Male rats receiving a single intraperitoneal dose of cadmium exhibit significant decreases in hepatic microsomal metabolism of a variety of substrates. The threshold cadmium dose is 0.84 mg Cd/kg, and the effect lasts at least 28 days. Mechanistically, the inhibitory effect results from decreased cytochrome P...

The aim of this study was to remove Cd by ion-exchange resin Amberjet 1200H in flow condition. The adsorption characteristics of metal onto the resin were accurately described by Freundlich isotherms. The ion exchange of cadmium on resin follows pseudo-second-order kinetics. Ion exchange capacities of the cadmium on the ion exchange resin was studied in metal solution. The capacities of sorptio...

Work in cadmium (Cd) smelter and smoking cigarettes damages teeth and oral mucosa which are protected by tissue and salivary glycoconjugates: glycoproteins, glycolipids, and proteoglycans. We worked out a rat model imitating human "environmental" and "occupational" exposure to cadmium using 5 mg Cd and 50 mg Cd/l in drinking water, respectively. In submandibulary glands of exposed to Cd rats, w...

Various metals, in trace amounts, are essential for proper biological functioning. However, there are many heavy metals that are toxic and exposure to their high intake may result in serious adverse effects on health. Cadmium (Cd) is one of the most toxic pollutants in environment. Accumulation of Cd in blood affects the kidney and liver. The toxicity of cadmium is much affected by deficiency o...

Heavy metal resistance by bacteria is a topic of much importance to the bioremediation of contaminated soils and sediments. We report here the isolation of a highly cadmium-resistant Klebsiella planticola strain, Cd-1, from reducing salt marsh sediments. The strain grows in up to 15 mM CdCl(2) under a wide range of NaCl concentrations and at acidic or neutral pH. In growth medium amended with t...

The objectives of the study were to determine the physiological and toxicological effects of chronic cadmium exposure on juvenile rainbow trout in soft water. Particular attention focused on acclimation, on comparison to an earlier hard water study, and on whether a gill surface binding model, originally developed in dilute soft water, could be applied in this water quality to fish chronically ...
