Heavy metals in soil are a potential threat to ecosystems and human well−being. Understanding the characteristics of heavy metal pollution prediction ecological risk crucial for regional eco−environment agricultural development, especially irrigation areas. In this study, Xiaohe River Irrigation Area Loess Plateau was taken as study area, concentration, well their accumulation degree distributi...

accumulation of trace metals in sediment can cause severe ecological impacts. the present study determines the elemental concentrations and chemical partitioning of heavy metals in surface sediment of shadegan wetland. shadegan wetland is one of the most important wetlands in southwest of iran and it is in ramsar-listed wetlands. for this purpose, 7 sampling stations were selected for sediment ...

The goal of this research is to assess hazardous heavy metal levels in PM2.5 fractioned road dust order quantify the risk inhalation and potential health effects. To accomplish this, Inductively Coupled Plasma Mass Spectroscopy (ICP-MS) was used determine concentrations eight metals (Cr, Cu, Ni, Zn, Cd, As, Pb, Hg) portion samples from five different land use areas (commercial, residential, ind...

Water and sediment samples have been collected from five different stations, located along Djendjen River between February and June, 2016 so that the concentrations of Cd, Ni, Zn, and Cu could be determined. The extent of the sediment pollution has been assessed, using the multiple pollution indices, namely Contamination Factor (CF), Pollution Load Index (PLI), and the geoaccumulation index (Ig...

The lake management strategy of sediment dredging (removal) is periodically undertaken in shallow, eutrophic Mogan Lake, an important recreation area. This study aims to use certain indices - enrichment index (EF), contamination/pollution (CF), degree contamination (Cd), pollution load (PLI), geoaccumulation (Igeo), potential ecological risk (Eri), integrated (PER), and mean probable effect con...

Polluted sediments limit the useful and biotic life of a water reservoir. Therefore, classification verification contamination pollution levels reservoirs are essentials for preservation biota to organize actions environmental management. Thus, aim this study is determine concentrations potentially toxic metals [lead (Pb), zinc (Zn), nickel (Ni), copper (Cu), cadmium (Cd)] in sediment samples c...

When residents of Volos, a city in central Greece, are trying to recall their daily life after the end quarantine due COVID-19, soil pollution survey provided valuable insights, which compared with 4-year study carried out that area before pandemic period. Using appropriate indices, namely contamination factor (CF), load index (PLI), geo-accumulation (Igeo), ecological risk (Er), and potential ...

lead as non-essential metal, is known the source of toxicity and impacts on the environment and humans. the goal of recent paper is to determine the pb concentration of road and road margin dust of ghamishlu wildlife refuge in isfahan province with an area about 120,000 hectares surrounded by four main roads. traffic load in the southern freeway have been reported as about 3600-19000 cars/day. ...

The increasing industrial activities, number of vehicles on road and population in large cities causes the contamination air urban environment, eventually affect human health. Therefore, aim this study was to collect soil dust samples from twelve roadside academic institutions Dhaka City, Bangladesh. One sites is control site for study. elemental (Ca, Fe, K, Ti, Sr, Zn, Zr, Rb, Cr, Ni, Pb Cu) c...
