Consumption of food contaminated with heavy metals is a major source of health problems for man and animals. Three commonly edible Leafy vegetables (Amaranthus hybridus, Celosia argentea ,Cochorus olitoris) from Agboju and Iba markets , Lagos Nigeria were sampled, identified, digested and analyzed with the aid of Atomic Absorption Spectrophotometer (AAS) as directed by APHA (American Public Hea...

The influence of zinc on the activity of antioxidant enzymes in the blood of rats intoxicated with lead was studied. Exposure to lead at the concentration of 500 mg/dm for 6 weeks caused a decrease in the activities of SOD, GSH-PX and GR as well as an increase in MDA concentrations in the serum. Zinc at the concentration of 60 mg/dm administered for a period of 2 weeks after exposure to cadmium...

The Udu River is a major source of commerce and provides water for agricultural domestic use to the people, hence we studied physicochemical parameters (pH, electrical conductivity, TSS, TDS, turbidity, Salinity, DO, COD, BOD, chlorides, sodium, potassium, total hardness, alkalinity, nitrates, ammonium, sulphates) as well evaluation degree metal contamination (iron, zinc, cadmium, nickel, coppe...

Contamination of animal feed materials by cadmium cannot be entirely avoided given its prevalent occurrence in the environment. Current statutory maximum levels for feedstuffs successfully prevent toxic effects in farm animals. Dietary cadmium exposure affects the absorption of trace elements, particularly that of copper resulting in an apparent copper deficiency in ruminants. In turn, high cop...

To investigate the relationships of trace element concentrations vs hematopoiesis and iron parameters, we measured lead, copper, zinc, cadmium, and ferritin levels in 251 healthy adolescents. Concentrations of trace metals were determined by atomic absorption spectrophotometry. There were no significant gender-related differences in serum copper or serum cadmium concentrations. However, blood l...
