  • Monitoring of Heavy Metal Content in Fruits and Vegetables

    The content of lead (Pb), copper (Cu), zinc (Zn), cobalt (Co), nickel (Ni), and cadmium (Cd) in some selected fruits and vegetables from the Misurata City Market, Libya, were measured using atomic absorption spectrophotometry. The results of this study showed that the average concentrations detected ranged from 0.02 to 1.824, 0.75 to 6.21, 0.042 to 11.4, 0.141 to 1.168, 0.19 to 5.143, and 0.01

  • Assessing the Levels of Pb, Cd, Zn and Cu in Biscuits and

    Pb, Cd, Zn, Hg, Mg, Mn, Cu, Co. Though some of these metals (e.g. Zn, Cu, Co, Mn) are classified as essential elements, when present in the body above certain concentrations, they can become harmful causing various health conditions. Metals like Pb and Cd have no known biological functions and may

  • Bioaccumulation of heavy metals in terrestrial

    The internal Pb, Cd and Cu concentration increased with the soil concentration for most taxonomic groups in the order Pbgt;Cdgt;Cu. Body concentrations of Zn were quite constant over a range of soil concentrations. The differences in accumulation level between taxonomic groups show the relevance of including detailed information on feeding

  • Pollution characteristics, sources, and health risk

    The heavy metal concentrations and I geo values in each studied city were demonstrated in Table S2. The I geo values for Cu, Zn, Cd and Pb were in the range of 0.8427.154, 1.3055.790, 0.6778.887 and 4.0555.627, respectively. The distributions of heavy metals in street dust on a national scale are illustrated in Fig. 2, which is based on the standard classes of I geo.

  • Sedimentary exhalative deposits

    The Sullivan Pb Zn Mine in British Columbia was worked for 105 years and produced 16,000,000 tonnes of lead and zinc, as well as 9,000 tonnes of silver. It was Canada's longest lived continuous mining operation and produced metals worth over $20 billion in terms of 2005 metal prices. Grading was in excess of 5% Pb and 6% Zn.

  • Potential ecological risk of heavy metals in sediments

    The m ERM Q calculated for the sampling sites (based on metals Cd, Cr, Cu, Ni, Pb and Zn) ranged from 0.01 to 0.34 (mean value of 0.15) (Fig. 3a), indicating that the combination of Cd, Cr, Cu, Ni, Pb and Zn may have a 30 % probability of being toxic. Only eight stations (40 %) have ERMQ (lt;0.1) and are categorized as non toxic and the rest of

  • Monitoring of Heavy Metals Content in Soil Collected from

    The highest values for Pb (1.52) and Cd (2.23) are in Benghazi Street. The highest values for Cu (1.76) and Zn (3.56) are found in Sadon Swihli Street, while the highest value for Fe (3.43) is found in Qasr ahmed street. This indicates that the urban soil in these areas are significantly contaminated by the corresponding metals.

  • Cadmium, Lead, Copper and Zinc in Breast Milk in Poland

    Calculation of Metals Intake. The mean intake of Cd, Pb, Cu and Zn in breast milk was calculated for infants aged 1, 3, 6 and 12 months. Since it is difficult to calculate the daily intake of milk by a breast fed infant, the supply of powdered milk, as recommended in Poland, was used as a reference value .The calculation of the tolerable intake of toxic metals was based on mean infant body
