the aim of the present study was to determine the levels of cadmium in the muscle, liver and kidney of cattle from isfahan and to compare the results with those reported by other countries and with the maximum acceptable levels for human consumption. samples of muscle, liver and kidney from 60 animals aged 1–10- year-old were collected from the carcasses slaughtered at isfahan abattoir. samples...

The objective of this study was to identify the presence of harmful drug residues (Chloramphenicol and malachite green/gentian violet) and toxic heavy metals (lead, cadmium, arsenic and mercury) in imported tilapia fillets. A total of 36 tilapia fillets were analyzed for these harmful chemical contaminants. The presence of veterinary drug residues were identified using competitive ELISA screeni...

Cymbopogon citratus (DC.) Stapf commonly known as lemon grass is used extensively as green tea and even as herbal tea ingredient across the world. Plants have the ability to uptake metals as nutrient from the soil and its environment which are so essential for their physiological and biochemical growth. Concentrations of these twelve trace elements, namely, Mg, Ca, Cr, Mn, Fe, Ni, Cu, Zn, Mo, A...

Ethanol consumption affects maternal nutrition, the mothers' antioxidant balance and the future health of their progeny. Selenium (Se) is a trace element cofactor of the enzyme glutathione peroxidase (GPx). We will study the effect of ethanol on Se bioavailability in dams and in their progeny. We have used three experimental groups of dams: control, chronic ethanol and pair-fed; and three group...

A case of arsenic contamination has recently been detected in the Lami coastal environment during the course of a heavy metal monitoring in Fiji’s coastal environment. Twenty two surficial sediment samples were sampled during the 20082009 period, extracted for arsenic and analysed using graphite furnace atomic absorption spectrometry. Two sites within the Lami estuary recorded the highest As le...

Lead concentrations were determined in the exhumed teeth of 28 people who lived in the Cape Town area before the combustion of leaded petrol (i.e. before 1922). The lead content of circumpulpal dentine was analysed by graphite-furnace atomic absorption spectrometry. The mean lead level in the dentine of primary teeth (N = 6) was 109 micrograms/g, while that in secondary teeth (N = 22) was 315 m...
