  • Heavy Metals Contamination in Vegetables Grown in Urban and Metal Smelter Contaminated Sites in Australia

    Abstract  Dietary exposure to heavy metals, namely cadmium (Cd), lead (Pb), zinc (Zn) and copper (Cu), has been identified as a risk to human health through the consumption of vegetable crops. This study investigates the source and magnitude of heavy metal contamination in soil and vegetable samples at 46 sites across four vegetable growing regions in New South Wales, Australia. The four ...


  • Heavy metal contamination in water and sediments of an estuary in southeastern Turkey

    The geochemical characteristics of some heavy metals (Cr, Cd, Pb, Zn and Ni) in the river and sea sediments, in the soil and in the river and groundwater of an estuary on the southeast coast of Turkey have been studied. In the sea sediments, the wastes from a chromium factory control these metal concentrations. The heavy metal contamination in the river sediments results from an existing chromite ...

  • White clover nodulation index in heavy metal contaminated soils– a potential bioindicator

    Received for publication January 10, 2008. The morphological effects of heavy metal stress on the nodulation ability of Rhizobium spp. and growth of white clover (Trifolium repens L.) were studied in the laboratory under controlled conditions. Fourteen topsoils were collected from an area with elevated metal concentrations (Cd, Zn, and Pb). White clover was cultivated using a specialized ...

  • Heavy metal contamination from electronic waste recycling at Guiyu, southeastern China

    This study evaluated the effect of electronic waste (e-waste) recycling activities at a regional center, Guiyu, Guangdong, China on heavy metal pollution in the surrounding waterway system. Surface water and sediment collected from the Lianjiang River and its tributaries were analyzed for concentrations of Cu, Pb, Ni, Cd, Hg, and As. Spatially, heavy metals in water and sediment samples decreased ...

  • Heavy metal removal - Case Study

    KDF 55 and 85 Provide Non-Chemical Water Treatment Media for Lead Removal and Other Heavy Metal Removal from Water In New Jersey's mercury contaminated groundwater - KDF media have been removing mercury to levels below the MCL since 1992. Redox media, non-chemical water treatment remove up to 98% of water-soluble cations (positively-charged ions) of lead, mercury, copper, nickel, chromium, and ...

  • Impact of heavy metals on the oil products biodegradation process

    Oil products continue to be used as a principal source of energy. Wide-scale production, transport, global use and disposal of petroleum have made them major contaminants in prevalence and quantity in the environment. In accidental spills, actions are taken to remove or remediate or recover the contaminants immediately, especially if they occur in environmentally sensitive areas, for example, in ...
