Electric-field-induced phase transition in single-crystal lead zinc niobate
      
The behavior of lead zinc niobate, a relaxor ferroelectric, in electric fields has been studied by dielectric, optical transmittance, and small-angle light scattering techniques.
      
Research on natural plants in the lead/zinc mine in northwestern Guizhou Province
      
The complex antimony-lead/zinc deposit at Rujevac/Yugoslavia; its specific geochemical and mineralogical features
      
Since 1973, about 500,000 tons/yr of metal-rich particulate tailings from a lead/zinc flotation mill have been discharged through a submarine outfall into a two fjord system on the west coast of Greenland.
      
Superior electromechanical performance over PZT, in lead zinc niobate (PZN)-lead zirconium titanate (PZT) thin films
      
Strongly oriented thin films of lead zinc niobate (PZN)-lead zirconium titanate (PZT) with (La,Sr)CoO3 lower electrodes were grown on MgO {001} substrates by pulsed laser deposition.
      
Two pilot-scale treatment wetlands were constructed and monitored at an active lead/zinc mine (Tara Mines) in Ireland to treat alkaline mine water with elevated sulfate and metal levels.
      
Animals of the same species taken from a heavy metal polluted site in the vicinity of a lead/zinc smelter also showed the presence of hsp 70.
      
Lead magnesium niobate (PMN) based binary with lead titanate (PT), lead iron niobate (PFN) and lead zinc niobate (PZN) and ternary with PZN-PT and PFN-PT solid solutions have been synthesized.
      
A small town close to a lead/zinc smelter was experiencing unusually high concentrations of sulfur dioxide during certain drainage flow conditions.
      
A co-operative approach to risk management in an active lead/zinc smelter community
      
Trail, Canada has been the site of a large lead/zinc smelting facility since 1916.
      
The soils were collected from the site of a metal refinery, an old lead zinc mine spoil tip and from a field which had been treated with sewage sludge.
      
Risk assessment for safety of soils and vegetables around a lead/zinc mine
      
Environmental accumulation of heavy metals in the vegetable plantation soils was proportional to heavy metal accumulation in vegetables and both were inversely proportional to the distance from the lead/zinc mine.
      
Parsley, bean and carrots were fumigated using SO2 in concentrations ranging from 0.35 mg m-3 (0.13 ppm) to 4.5 mg m-3 (1.7 ppm) with and without lead/zinc/cadmium-containing particulate matter.
      
A comparative study of the concentrations of cadmium in ecosystems developed on tailings from lead/zinc mines was undertaken.
      
High concentrations of Pb (5394 mg kg-1) and Zn (9607 mg kg-1), mainly in insoluble forms, were recorded in the lead/zinc-mine tailing, as well as very low biochemical activity.
      
This fact could restrict the use of these olive-organic amendements as useful materials in reclamation of lead/zinc-mine tailings.
