And rhus chinensis rhus chinensis mill. were collected. the concentration of oreforming elements including au, ag, pb, zn, cu, as, fe, andere analyzed. based on the investigation of two mine profiles, it can be found that au, pb, as, and fe were mainly enriched in laterite layer and the brown clay layer atepth of 511 m.
Heavy metals are metallic chemicals withelatively high density that are toxic, persistent and hazardous to human health at low concentrations .these include mercury hg, lead pb, copper cu, cadmium cd, arsenic as, chromium cr, thallium ti, manganese mn, zinc zn, and nickel ni .some of these metals fe, mn, cu and zn are essential for.
The concentration of fe, cu, cd, zn, and pb was found to be very much higher than both the continental crust and world surface rock average values as shown in table0, 22, 23. concentration of ni and cr was found to be much below that of the two reference values.
