Lead (Pb), cadmium (Cd), and arsenic (As) are three common non-essential heavy metals found in urban soils and can prove toxic to animals, humans, and some plants at low concentrations. The main exposure pathways of heavy metals in humans are through ingestion and inhalation of soil particles and ingestion of contaminated food. When dealing with contaminated soil in urban environments, activiti...

Heavy metal accumulation in aquatic organisms has been an important issue due to environmental pollution resulting from anthropogenic activities. In this study, Cr, Mn, Fe, Cu, and Zn in the selected fish species (Mullus barbatus, Solea solea, and Siganus rivulatus) from three consecutive bays (İskenderun, Mersin, and Antalya from North-Eastern Mediterranean Sea) were considered to provide some...

in vascular plants, the soil solution is transported from the roots to the leaves through smalldiameter vessels found in the xylem; this transport not only allows the nutrient uptake but also the accumulation of heavy metals in their shoots. by analogy to this phenomenon, the present study aimed at the evaluation of heavy metals transport (pb, cr, as, cd, zn, ni and al) in ph 4 and ph 8 solutio...

background: the rapid increase in agricultural and industrial development has made heavy metal pollution a serious environmental problem and public health threat; therefore, removal of heavy metals from water is important. the current study prepared dnph@sds@fe3o4 nanoparticles as a novel and effective adsorbent for removal of hg(ii) ions from an aqueous solution. methods: a selective adsorbent...

industrial effluents consist many pollutant and heavy metals. bacteria isolated from industrial west water ground may have potential to tolerate heavy metal. in this study we isolate a citrobacter sp. which can resist heavy metal like cu and pb. slurry from industrial west water ground was collected from 22.0663 n, 88.1041 e. the heavy metal content and other parameters of soil were estimated. ...

mangrove trees occur along the coastal areas of bushehr province, south iran and these plants have been used in traditional medicine and fodder for centuries. heavy metals are known to pose a potential threat to terrestrial and aquatic biota. however, little is known on the levels of heavy metals found in mangrove in iran. to understand levels of heavy metals and identified heavy metal source, ...

fractionation studies on the sediment samples provide valuable information on the nature of the metals bound to the sediments. thirty three sediment samples of river adyar were collected during two seasons and speciation study was carried out. the industrial and domestic effluents are directed into the river course at many points in the middle and lower of the adyar river. to ascertain the exte...
