Soil pollution refers to the contamination of soil by harmful substances that can have adverse effects on plant and animal life, it also negative affects health-being humans. The sources include industrial activities, agricultural practices, mining transportation activities. contaminants in heavy metals, pesticides, herbicides, fertilizers, petroleum products, other chemicals. These seep into a...

the chemical speciation of heavy metals (arsenic, chromium, copper, lead, zinc and tin) in the sediments offormer tin mining catchment bestari jaya, peninsular malaysia was determined by using the latest version of the community bureau of reference, usually called the bcr 3-step sequential extraction procedure. furthermore, a fourth step was introduced for digestion and analysis of the residue....

Urban ares are subjected to intensive pollution due continuous anthropogenic activity. In order assess the influence of thermal power plants and waste incineration on City Moscow recreational areas, mass fractions 37 major trace elements were determined using instrumental neutron activation analysis in soil samples collected at two different depths vicinity more potential contamination sources....

For the pollution assessment and quantitative source apportionment of heavy metals in surface dust, a total 52 dust samples were collected from bus stops Tianshui City. The geoaccumulation index (Igeo) potential ecological risk (RI) used to analyze levels caused by metals. Positive Matrix Factorization (PMF) receptor modeling geo-statistics employed results as follows. ① Except for Mn, Co V, me...

Previously conducted studies have established that soil contamination by trace elements (TEs) around coal mines affects ecological biodiversity and human health. One of the ways to protect health surrounding population mine sites is through assessment impacts accurate procedures for establishment relevant reclamation plan. The aim study develop an applied methodological approach easily assess q...

in this study, the mineralogical composition and concentration of heavy metals in surfacesediment of north west persian gulf (musa estuary and hendijan coastline) were investigated. fifteensampling sites were selected and the sediment samples were collected using peterson grab sampler in august2013. xrd analyses demonstrated that the sediments of study area are principally composed of calcite,q...

This study aims at determining the level of pollution heavy metals (Cr, Cu and Hg) in soils illegal mining sites Atiwa East District Ghana. The concentrations Copper (Cu), Chromium (Cr), Mercury (Hg) were determined using Atomic Absorption Spectrometry (AAS). extent metal risk assessment was analyzed site. Thirty (30) soil samples collected from three (3) within district. average levels Cu, Cr,...

in this study, concentrations of heavy metals in soils around a zn-smelter in qeshm island, iran, are investigated. calculated geoaccumulation index (igeo), contamination factor (cf), and contamination degree (cdeg) values indicate surface soil contamination by toxic metals (as, cd, pb, and zn). the results also indicate that most contaminated areas are located in the vicinity of the smelter an...

Land use of sewage sludge is the primary disposal method in Shanxi, accounting for 42.66% of all. To determine the ecological risk of heavy metals in sewage sludge, contents of seven heavy metals in sewage sludge from 9 municipal waste water treatment plants (WWTPs) that had the highest application for land use were determined. The order of the measured concentrations was: Zn > Cr > Cu > Ni > P...
