OBJECTIVE To measure the concentrations of the trace elements lead and cadmium in human placenta and in maternal and neonatal (cord) blood. To assess the influence of the strongly polluted environment on the content of metals in tissues and on the permeability of placenta to cadmium and lead. Various methods of mineralisation were tested before analysis. METHODS Graphite furnace atomic absorp...

s Cadmium (Cd) is a toxic heavy metal that enters the environment through various anthropogenic sources, and inhibits plant growth and development. Cadmium toxicity may result from disturbance in plant metabolism as a consequence of disturbance in the uptake and translocation of mineral nutrients. Plant nutrients and Cd compete for the same transport-ers and, therefore, presence of Cd results i...

BACKGROUND Cadmium (Cd) is used in many industries. High-level exposure is associated with severe kidney and bone damage. AIM This study investigates the possible effect of occupational cadmium exposure on parathyroid gland and some minerals in workers. METHODS Environmental air monitoring of cadmium was done. Serum and urine cadmium levels, kidney function, some minerals, and plasma parath...

Cadmium (Cd) is a ubiquitous environmental pollutant of increasing worldwide concern. It is thought to be of greater concern to rapidly industrializing developing countries because of the increasing pace of industrial activities in these countries with increasing consumption and release into the environment. Traditionally, health concerns in exposed human populations have revolved around the as...

The minimum concentration of cadmium (Cd), by Chinese cabbage grown on Cd contaminated soils that can initiate toxicity in human liver cells using in vitro digestion coupled with Caco-2/HL-7702 cell models was studied. Cadmium bioaccessibility in the gastric phase for yellow soil (YS) cabbage (40.84%) and calcareous soil (CS) cabbage (21.54%) was significantly higher than small intestinal phase...

The aim of the present study was to establish to what degree a one-year exposure of rat females to 5, 50 and 100 mg Cd/l affects the weight of the submandibular glands and their cadmium levels. We observed a decrease in the weight of the submandibular glands in the rat females from Groups I, II and III, compared to the control rats. We also found an increase in cadmium levels in the submandibul...

in the present study, cadmium (cd) accumulation capabilities of aquatic macrophytes ceratophyllum demersum, bacopa monnieri and rotala rotundifolia were determined after treating both individual and triple macrophytes. the macrophytes were treated with cd at 0, 0.1, 1 and 10 mg/l concentrations in a controlled chamber for 12-days. cadmium accumulations increased with increasing cd concentration...

Amphibian larvae at contaminated sites may experience an alteration of metamorphic traits and survival compared to amphibians in uncontaminated conditions. Effects of chronic cadmium (Cd) exposure on the metamorphosis of American toads (Bufo americanus) and southern leopard frogs (Rana sphenocephala) were determined. The two species were reared separately from shortly after hatching through met...
