Jinchanghe is a Zn Pb Fe Cu skarn deposit in the northern Baoshan block southwestern China It is a typical distal skarn deposit with orebodies in the Cambrian Hetaoping Formation limestone and calcareous siltstone The skarn minerals display a vertical zonation with garnet skarn in the lower part and pyroxene skarn in the upper part Economic metals are also
Purslane Growth Characteristics and its Cd Cu Pb and Zn Contents in Aerial Parts and Roots Plant growth parameters measured were height and dry weights of the aerial biomass and roots of purslane Table 1 As for the height the various treatments did not affect it as average values across amendments were found with non significant differences
The processing of fine dust from copper smelters in Kazakhstan is an urgent task The currently used technology of hydrometallurgical dust processing which involves leaching with sulfuric acid to produce lead cake and a solution containing copper and zinc fails meet modern requirements The significant content of arsenic in the dust up to 15% hinders

The adsorption of metals onto Fe oxides hydroxides and oxyhydroxides hereafter denoted as Fe oxides for simplicity is an important process that can influence metal mobility and bioavailability in soils and aqueous environments and which has been studied for more than forty years Raogadde and Laitinen 1974 Due to the development of advanced
From the Middle Ages until the beginning of the twentieth century extensive Zn Pb mining and smelting was carried out in East Belgium By lack of waste treatment techniques and sustainable management practices metal bearing slags and unprocessed waste were dumped in huge tailings which still represent an important source of contamination A
Sungai Puloh mangrove estuary supports a large diversity of macrobenthic organisms and provides social benefits to the local community Recently it became a major recipient of heavy metals originating from industries in the hinterland as a result of industrialization and urbanization This study was conducted to evaluate mobility and pollution status of heavy
The elements of P Cd Cu Pb Se and Zn were further investigated Cu Cd Pb and Zn are frequently studied metals Goodyear and McNeill 1999 as elevated levels might be toxic to organisms Zn and Cu are essential trace metals; whereas Cd and Pb are in general considered non essential Rainbow 2002; Hejna et al 2018 P is an
Metal pollution in urban soils due to smelting and electroplating has become a severe problem in China In this study the concentration chemical fraction and leaching behavior of typical metals Cu Zn Cd and Pb in soil samples from ten metallurgical sites were studied The results show that some of the soils were polluted with Cu and most were heavily polluted
