Since toxicity is time dependent, short-term toxicity tests may overlook mixture effects, because chemical accumulation within an organism takes time. We therefore studied the effects of cadmium on the toxicokinetics of pyrene and its metabolites in the soil-dwelling collembolan Folsomia candida exposed through Lufa 2.2 soil. Single pyrene was rapidly taken up and steady state was reached withi...

Cadmium accumulation in grain of durum wheat (Triticum turgidum L. var. durum) represents a concern to consumers. In an effort to understand the regulation of Cd accumulation in maturing grain, the remobilization of 109Cd applied to stem and flag leaves was examined in two near-isogenic lines that differ in grain Cd accumulation. Absorbed 109Cd was primarily retained in the labelling flap (50-5...

Accumulation of heavy metals from various oxides with adsorbed cadmium by wetland plant Phragmites australis was studied to evaluate the fate of heavy metals in the sediment of constructed wetlands. Hoagland solution was used as nutrition supply, and single metal oxide with adsorbed cadmium was applied as contaminant to study the accumulation characteristics of cadmium and the substrate metals ...

This study was designed to evaluate the effects of simultaneous coexposure to inorganic mercury and cadmium on the renal and hepatic disposition of each metal. Dispositional changes were assessed in rats 1 h and 24 h after the coexposure to relatively low doses of the metals (which individually are nonnephrotoxic in rats). The rational for studying mercury and cadmium is that both of these meta...

A redundant nickel/cadmium battery worker was investigated for non-specific fatigue after completing five years in the industry. Sensitive techniques for in-vivo organ cadmium measurement showed a moderate accumulation in the liver but a very large concentration in the kidneys. Despite this, overall glomerular and tubular function were not impaired. It was concluded that the mechanism of protei...

Cadmium is a main toxic pollutant and poses a considerable threat to human health. In other to study the effect of Cd stress on traits of garden cress and radish, an experiment was conducted based on a completely randomized design in an aeroponic system. In this study CdCl2</sp...

The heavy metal cadmium is a widely dispersed environmental pollutant that has no biological function in the human body and is known to cause several adverse health effects, mainly on kidneys and bone and the endocrine system. Little is known about effects in early life. The main source of exposure in a non-smoking population is via basic foods such as cereals (e.g. wheat and rice) and vegetabl...

the pollution of soil by heavy metals is considered to be quite a big problem in many areas ofthe world. to limit the accumulation of lead and cadmium from soil in the products, a correct understanding ofthe characteristics and specifications of the translocation of cadmium and lead is necessary. in order to evaluatethe effects of cadmium and lead interaction on zinc and manganese concentration...

In the present investigation we studied the role of salicylic acid in cadmium induced physiological and biochemical changes and the possible induction of oxidative stress in developing rice roots. 24h cadmium treatment resulted in the inhibition of root dry biomass, root elongation and increased cadmium accumulation in roots. Salicylic acid presoaking for 16hrs resulted in protection against ca...
