Heavy metal content and speciation in groundwater of the Guadiamar river basin

Levels of some toxic elements and frequency of bacterial heavy metal resistance in sediment and sea water

“…More accurate mapping of pollution is therefore achieved by examining marine sediment than sea water. Heavy metal pollution has drawn increasing attention worldwide owing to a dramatic increase in anthropogenic heavy metals in ecosystems through air, water and soil (Fang et al 2000;Adamo et al 2002;Santos et al 2002;Woitke et al 2003). In estuaries, river water velocity decreases, relative to the river channel areas, as fresh water mixes with sea water.…”

Nanotechnology in Industrial Wastewater Treatment

“…The waste streams produced from these industries have sometimes been left behind and hence polluted the surrounding soils, surface water and ground water. Santos et al (2002) reported the heavy metal pollution of groundwater in the alluvial aquifers of the Guadiamar River in Spain by Aznalcollar mine tailing spill. The excessive utilization of some heavy metals contained agrochemicals in agriculture can be another source of heavy metal pollution.…”

Chemical Fraction of Heavy Metals in an Oasis Soil and Their Bioavailability to Cole Crops

“…Many studies have shown that heavy metals can be retained between solution and solid phase and their further redistribution among solid-phase components in soil could enable the prediction of metal mobility and availability to plants (Abollino et al, 2002;Santos et al, 2002). Bioavailability is defined as the part of the total concentration of a chemical that is available to receptor plants (Sarwar et al, 2010).…”
