ZINCPharmer (http://zincpharmer.csb.pitt.edu) is an online interface for searching the purchasable compounds of the ZINC database using the Pharmer pharmacophore search technology. A pharmacophore describes the spatial arrangement of the essential features of an interaction. Compounds that match a well-defined pharmacophore serve as potential lead compounds for drug discovery. ZINCPharmer provi...

phytoextraction is a remediation technology that uses plants to remove heavy metals from soil. the success of a phytoextraction process depends on adequate plant yield (aerial parts) and high metal concentrations in plant shoots. a pot experiment was conducted to investigate the combination effects of plants [sunflower (helianthus annuus) and canola (brassica napus)] with soil treatments (manur...

Waste metals in the form of metal oxide (hydroxide) sludges are generated in significant amounts by the metal finishing industries, and their accumulations pose problems for disposal and challenges for recycle. The availability of technically feasible efficient separations of metals such as nickel, cobalt, chromium, cadmium, copper, tin, zinc, lead, manganese, molybdenum, and titanium from plat...

introduction due to mining, considerable amounts of heavy metal bearing mineralsare scattered in the atmosphere in the form of dust and make the surrounding air, water and soils polluted.runoff water movingfrom the mountainstowardsplains may also transport heavy metals from mines to the soils.one type ofpollutions is contamination withheavy metals.the purpose of the present research has been to...

Determination of trace elements in food is of great importance, as some of them have nutritional significance, whilst others are toxic. Long-term exposure to low levels of toxic metals could be important, especially in relation to children. Differential Pulse Anodic Stripping Voltammetry (DPASV) is applied to simultaneous determination of lead, cadmium, copper and zinc in dry ash infant formula...
