We present high spatial-resolution mapping of soil lead (Pb) concentrations in a small-urban residential setting. X-ray fluorescence was used to measure soil Pb at170 properties in the City Park neighborhood of Appleton, Wisconsin. Greater than two-thirds of soil samples collected from drip lines contained more than 400 μg g of Pb, and one third exceeded 1200 μg g. Soils adjacent to homes built...

in desert reclamation strainer plants can be used for improvement and decrease pollution of soil and water. this technology can be used to remove both inorganic and organic contaminants in soil. in this study, one year old acacia victoriae seedlings were exposed to pb (no3)2 in 5 different concentrations; 0, 50, 250, 500 and 1000 mg pb l-1 for 45 days in two growing seasons. subsequently, the h...

the pollution of soil by heavy metals is considered to be quite a big problem in many areas ofthe world. to limit the accumulation of lead and cadmium from soil in the products, a correct understanding ofthe characteristics and specifications of the translocation of cadmium and lead is necessary. in order to evaluatethe effects of cadmium and lead interaction on zinc and manganese concentration...

in this research a pot experiment was carried out to investigate the remediation ability of e. camaldulensis dehnh inlead-zinc (pb-zn) contaminated soil. the study also investigated the effects of ethylenediaminetetraacetic acid(edta) and diethylenetrinitrilopentaacetic acid (dtpa) on the phytoremediation efficiency of the plant species, andharvest time as a suitable dose of chelating agents wa...

background: the presence of lead in natural waters has become an important issue around the world. lead has been identified as a highly toxic metal that can cause severe environmental and public health problems and its decontamination is of utmost importance. the aim of this work was to evaluate the adsorption of lead (pb(ii)) on waste tea leaves as a cheap purification method. methods: in this...

BACKGROUND Tetraethyl lead was phased out of gasoline in Uganda in 2005. Recent mitigation of an important source of lead exposure suggests examination and re-evaluation of the prevalence of childhood lead poisoning in this country. Ongoing concerns persist about exposure from the Kiteezi landfill in Kampala, the country's capital. OBJECTIVES We determined blood lead distributions among Kampa...

IN the past few years, pollution of the environment by lead has received considerable attention and evoked a variety of responses the more extreme of which have been readily accepted for publication in the National Press. The manifold purposes that man has found for the utilization of lead in the past and at the present time have caused its dissemination into the environment which, in some inst...
