The residues from the extraction of lead/zinc (Pb/Zn) ores of most Pb/Zn mines are permanently stored in tailings ponds, which require revegetation to reduce their environmental impact. This can only be done if the main constraints on plant establishment are evaluated. This can readily be done by field and greenhouse studies. To test this, the properties of different tailings from Lechang Pb/Zn...

faulty copper genes (almost always the result of consanguineous marriage) causes Wilson's disease. Heterozygotes are clinically well but may show some of the biochemical abnormalities. Excess copper damages first the liver and then as copper is released from the dying hepatocytes it affects the brain, eyes, kidneys, bones and joints, and possibly the parathyroid glands.8 The definitive biochemi...
