currently all the waste produced are collected and transferred to the only landfill of tehran,aradkooh (kahrizak), that is located in the south of tehran. this landfill has been in use for over 45 years that has received over 35 million tons of waste during its life. in the present investigation 40 soil samples were collected from aradkooh landfill to know about the origin of metals. the sample...

concentrations of cu, pb, cr, cd, mn, ni, fe and zn were determined in the muscle samplesof sarotherodon melanotheron from the fosu lagoon in cape coast using atomic absorption spectrophotometer. the results showed that, metal concentration in the fish muscle was in the order mn > zn > fe > pb > ni > cd > cu > cr. mean concentrations of pb and cd in the fish exceeded the maximum tolerable limit...

Street dust is a hazard for workers in traditional markets. Exposure time is longer than for other people, making them vulnerable to heavy metals in street dust. This study investigated heavy metal concentrations in street dust samples collected from different types of markets. It compared the results with heavy metal concentrations in heavy traffic and rural areas. Street dust was significantl...

The status of metal concentrations including Pb, Cd, Cu, Ni, Zn and Fe in six species of Padina were determined in polluted (Nayband Bay) and unpolluted (Bostaneh port) areas on the Coast of the Persian Gulf. The mean concentrations of metals in the sediment of two locations were: Pb (12.64), Cd (3.59), Cu (21.74), Ni (17.00), Zn (32.00) and Fe (677.53) µg g-1 dry weight, respectively. In ...

metals bioaccumulation in five organs of cirrhinus  mrigala , labeo  rohita and catla catla captured from three industrial and sewage polluted downstream sites (shahdera = b, sunder = c and balloki = d) were compared with a non-industrial upstream site (siphon = a) during high (post monsoon) and low (winter) flow seasons of river ravi. mean concentrations of metals were significantly higher in ...

The current study considers the spatial and temporal variability in aerosol trace metal concentrations (Al, Fe, Mn, Cr, Cu, Pb, Cd, Zn) in the Levantine Basin of the Eastern Mediterranean, utilising an extensive sample library (n 1⁄4 621) collected between 1999 and 2001, at two coastal sites located at the northern, Erdemli (Turkey) and southeastern, Tel Shikmona (TS, Israel), region of the Bas...

concentrations of heavy metals were determined in muscles of kutum (rutilus frisii kutum) collected from the central part of the southern end of the caspian sea during february 2011. except for silver (ag) and nickel (ni) which were below the limits of detection, the average levels of arsenic (as), cadmium (cd), copper (co), chromium (cr), copper (cu), iron (fe), manganese (mn), lead (pb), sele...
