In the present study a novel approach has been made to evaluate the toxicity of cadmium in maize (Zea mays L. cv KJ9451) in terms of germination, seedling growth, pigment development and relevant enzyme activity and the possible remedial approach using potassium and copper to reduce cadmium toxicity. For the present investigations maize seeds were sown in petridishes on filter paper in triplica...

This study was conducted to determine the histopathological and biochemical effects of humic acid on cadmium stress in liver and kidney tissues of Salmo trutta fario, L. The fish were treated in four groups as follows and were exposed to chemicals for 7 days: control (C), cadmium (2 ppm) (Cd), humic acid (5 ppm) (HA) and humic acid + cadmium (Cd + HA). At the end of the experimental period, liv...

To characterize the histomorphologic effects of cadmium on adult newt testes, male Iberian ribbed newts (6 months post-hatching) were intraperitoneally exposed to a single dose of 50 mg/kg of cadmium, with histologic analysis of the testes at 24, 48, 72, and 96 h. Beginning 24 h after cadmium exposure, apoptosis of spermatogonia and spermatocytes was observed, and congestion was observed in the...

Cadmium is a transition metal ion that is highly toxic in biological systems. Although relatively rare in the Earth's crust, anthropogenic release of cadmium since industrialization has increased biogeochemical cycling and the abundance of the ion in the biosphere. Despite this, the molecular basis of its toxicity remains unclear. Here we combine metal-accumulation assays, high-resolution struc...

OBJECTIVES To study the body burden of cadmium and signs of tubular dysfunction in a rural population living near a closed nickel cadmium battery plant. METHODS Cadmium and N-acetyl-beta-glucosaminidase (NAG) in urine were measured in 72 subjects who lived close to the plant. RESULTS Residents living close to the plant had higher median urinary cadmium concentrations than those living farth...

This study compares the abilities of four low-cost materials: peels of peas, broad bean, and medlar, respectively and fig leaves, to remove cadmium from aqueous solutions. Kinetic data and equilibrium sorption isotherms were measured in batch conditions. Kinetics of cadmium sorption was contact time, initial cadmium concentration and sorbent type dependent. The results also showed that the kine...

BACKGROUND Cadmium is a ubiquitous environmental pollutant associated with increased risk of leading causes of mortality and morbidity in women, including breast cancer and osteoporosis. Iron deficiency increases absorption of dietary cadmium, rendering women, who tend to have lower iron stores than men, more susceptible to cadmium uptake. We used body iron, a measure that incorporates both ser...

OBJECTIVE Cadmium is known to affect the vascular tone of isolated blood vesselsin vitro and the arterial pressure of ratsin vivo. However, the mechanisms of cadmium actions on the vascular system have not been clarified. To elucidate the actions of cadmium on vascular tonus, effects of cadmium on vasocontractile and vasorelaxant responsesin vitro were investigated using aortic strips isolated ...

The general population is exposed to cadmium from food and smoking. Cadmium is a widely spread toxic pollutant that seems to be associated with cardiovascular diseases, although little is known if it contributes to the occurrence of atherosclerotic plaques and the process whereby plaques become vulnerable and are prone to rupture. We tested the hypotheses that cadmium exposure is associated not...

Cadmium is a toxic element ubiquitous in the environment, which damages biological systems in various ways. The major source of cadmium exposure is food. High cadmium content in the soil leads to high cadmium concentrations in certain plants such as grains (above all surface layers and germs), oil or non-oil seeds, fruit and vegetables. These food commodities are the crucial components of a veg...
