Population growth has led to the intensification of average daily traffic (ADT), highlighting vehicles as one major sources heavy metal (HM) pollution in cities. The objective this paper is conduct a spatial analysis HM associated with road-deposited sediments (RDSs), based on ADT observed main roads Latin American megacity (Bogotá, Colombia). following risk indices were considered: Geoaccumula...

The current study assessed the ecological–health risks of potentially toxic arsenic (As) and antimony (Sb) in vegetable Centella asiatica , topsoils, mangrove sediments sampled from Peninsular Malaysia. As concentrations ranged 0.21 to 4.33, 0.18 1.83, 1.32 20.8 mg/kg dry weight, for leaves, stems, roots vegetable, respectively. ranges Sb were 0.31–0.62, 0.12–0.35, 0.64–1.61 children’s target h...

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...

water and sediment samples were collected from six different stations, located along the nil river between february and june 2015. concentrations of cadmium, lead, zinc, and copper were determined. the extent of the sediment pollution was assessed, using the multiple pollution indices, namely contamination factor (cf), pollution load index (pli), and the geoaccumulation index (igeo). the result...

Heavy-metal pollution is a negative impact of municipal solid-waste landfills. The multiple transport pathways (including leachate, runoff, and waste gas) complex co-existing potential sources (such as agricultural activities) around landfills require combination different assessment methods source identification tools to address distribution risks. In this study, the distributions eight heavy ...

Heavy metals contamination in soil is one of the global issues, posing a threat not just to environment but also human health. Identifying source and distribution heavy metal pollutants around mining areas can provide scientific basis for future environmental control. Distributions (Cd, Cr, As, Ni) this study were evaluated using descriptive multivariate statistics further described geostatisti...

This study examined the spatio-temporality of heavy metal concentrations (Al, Cd, Co, Cr, Fe, Mn, Ni, Pb and Zn) in sediments Lake Bafa, one most important wetlands Turkey’s Aegean region. The evaluated sediment quality according to threshold effect concentration (TEC) probable (PEC) values based on guidelines (SQG), provided a potential ecological risk assessment (PERI) along with indices such...

This paper examined the efficiency of artificial neural network (ANN) and multivariate linear regression (MLR) models in prediction groundwater quality parameters such as ecological risk index (ERI), pollution load (PLI), metal (MPI), Nemerow (NPI), geoaccumulation (Igeo). 40 samples were collected systematically analyzed for mainly heavy metals. Results revealed that adopting measured is effec...

Pollution of river bottom sediments with heavy metals (HMs) has emerged as a main environmental issue related to intensive anthropopressure on the water environment. In this context, risk harmful effects HMs presence in Warta River, third longest Poland, been assessed. The concentrations Cr, Ni, Cu, Zn, Cd, and Pb collected at 24 sample collection stations along whole length have measured analy...

The accumulation of tailings from gold mining and smelting may result in PTE pollution. We investigated contamination a large amalgamated mine pond Pinggu County, Beijing. In November 2017, 30 soil samples were collected around the pond. concentrations pollution degree PTEs sources Sb, As, Cd, Cu, Pb, Zn Hg analyzed. average concentration these elements near (16.24, 28.29, 0.99, 171.04, 263.25,...
