The current study was conducted on the valley of Duhok and agricultural lands irrigated from it, where three sites were identified for collecting samples quarterly soil sediment using clean plastic bags purpose measuring lead, nickel, cobalt copper. Pollution load index (PLI), Nemerow pollution (PIN), Potential Ecological Risk (PER) Geo-accumulation Index (Igeo) also calculated according to int...

Areas polluted by heavy metals in soil may pose a major risk to human health and ecological environment safety. In this study, 89 samples were collected from four potato producing areas (Libo, Chishui, Panxian Weining) Guizhou Province, China, the concentrations of 9 analyzed measured. The aims study was evaluate pollution index some potato-producing Province using geoaccumulation method, load ...

The uncontrollable population growth is reaching Benin's rivers, especially the coastal lagoon, raising then thorny problem of pollution, which considerably accentuated by malevolent behavior populations. aim this paper to characterize degree contamination water and sediments lagoon in heavy metals (Cd, Cr, Zn, Cu, Pb Fe) through dosage with molecular absorption spectrophotometer type DR 3900. ...

Upper Cretaceous sedimentary rocks are widely exposed around Trabzon, Giresun and Gümüşhane in the eastern Pontides. The mainly composed of sandstones marls, thicknesses these range from 170 to 400 m. This paper focused on Late regions identify concentrations, sources, deposition environment conditions certain heavy metal(loid)s (Zn, Pb, Cu, Ni, As, Co, Mo V). Enrichment factor (EF), geo-accumu...

Heavy metal contents in road dust have been an important indicator of heavy pollution arising from traffic-related activities. In this study, 108 samples were collected four locations Hong Kong, namely Kwai Hing (industrial area), Sau Mau Ping (residential Sai Kung and Tai Lam (rural over a one-year period analysed for zinc (Zn), nickel (Ni), copper (Cu), lead (Pb), chromium (Cr), cadmium (Cd),...

Pollutants are persistent in the environment, taint food chain, and harm people's health because of their toxicity. In this study, mangrove snails called Cerithidea obtusa (C. Obtusa) were gathered from Southwest Johor, Malaysia, amounts macro micro elements Ca, Fe, K, Mg, Na, As, Mn, Zn soft tissues, shells, related surface sediments analysed. The Neutron Activation Analysis (NAA) method was u...

Background: Industrial pollution of metals is a serious environmental concern. The presence Sarcheshmeh copper (Cu) mine and the possibility soil pollution, were primary motivations for evaluating heavy in this area. Methods: A total 171 10 sediment samples collected randomly from study area Cu, aluminum (Al), molybdenum (Mo), lead (Pb), cadmium (Cd) determination. USEPA method was used to acid...
