Heavy metals (Cd, Cu, Hg, Pb and Zn) concentration were determined in the marine bivalve Pinna nobilis along the Balearic Islands, comparing a protected area with two sites with strong anthropogenic influence. Analyses of Cabrera and Mallorca indicated that heavy metal concentration were generally higher in the most of samples, specially in Santa Maria bay (Cabrera, MPA), and Magaluf (Mallorca,...

Background: The release of metals from industrial factories is one of the most important sources of environmental pollution. The present study aimed to determine the concentration of heavy metals like cadmium (Cd), chromium (Cr), manganese (Mn), nickel (Ni), and lead (Pb) in dust around the cement factory. Methods: A total of 22 dust samples were collected from areas around the cement factory...

levels of the heavy metals copper (cu), zinc (zn), lead (pb), cadmium (cd), chromium (cr), nickel (ni), iron (fe) and manganese (mn) were determined by graphite furnace atomic absorption spectrophotometer (model 67og) in coastal water, sediments and soft tissues of the saccostrea cucullata, from the intertidal zone at five stations in the gulf of chabahar on the iranian coasts along the oman se...

This study investigated bioreduction of selenite by anaerobic granular sludge in the presence of heavy metals and analyzed the fate of the bioreduced selenium and the heavy metals. Selenite bioreduction was not significantly inhibited in the presence of Pb(II) and Zn(II). More than 92% of 79 mg/L selenite was removed by bioreduction even in the presence of 150 mg/L of Pb(II) or 400mg/L of Zn(II...

Seasonal variations of three heavy metals (Pb,Cd, Ni) in Pinctada radiata have been conducted in Hendorabi and lavan Island from March 2011 to march 2013, edible oysters are best pollution indicator organism in aquatic environment. The soft tissue of Pinctada radiata and sediment was analyzed to detect some potentially toxic metals as Pb, Cd, Ni with a flame AAS and statistical analyses were pe...
