Evaluation of stream sediment contamination by potentially toxic elements around mining and farming areas (SE Nigeria)
In this work, the concentrations of the potentially toxic elements in stream sediments in SE Nigeria were assessed for pollution monitoring in mining, quarrying, and farming areas. The levels of iron, molybdenum, vanadium, copper, lead, zinc, nickel, cobalt, manganese, chromium, barium, and beryllium were determined. The concentrations of the elements were in the order of Fe > Ba > Mn > Cr > Zn...

15 صفحه اولStudy of contamination, sources and health risk of potentially toxic elements in dusts of Tehran’s elementary schools
Concerns about dust contamination with potentially toxic elements are especially important in environments such as schools (particularly elementary schools) because children are more vulnerable to contaminants than adults. Therefore, due to the diversity of air pollution sources in Tehran, the present study was conducted to determine the severity of pollution, origin and health risk assessment ...
متن کاملPotentially Toxic Elements Contamination in Sediment, Surface and Pore water of Maharlu Saline Lake, South - West Iran
Maharlu Lake, located in the SW of Iran, has acted as a sink for various wastewater discharges in the last few decades. This study aimed at assessing potentially toxic elements (PTEs) distribution in sediment, surface and pore water samples of Maharlu Lake. To achieve that, the samples were collected from each compartment and the total concentration of PTEs (Al, Fe, Sc, Cr, Co, Ni, Zn, As, Sb, ...
متن کاملEvaluation of Potentially Toxic Elements Pollution Indices in Rangeland Northwest of Chadegan city (Isfahan Province)
Abstract Today, the pollution of Rangeland soils by various destructive pollutants has become one of the human-environmental problems. Lacking proper management of organic matter discharge can also increase the concentration of salts, heavy metals, and pathogenic microorganisms. In this study, to investigate and measure the concentration of toxic elements, 128 soil samples of Chadegan region w...
