Cu、Ni、Pb and Cd showed more affinity to the oxidizable metal fraction. Bio-availability of all the measured metals, except Cd,decreased with the increase in composting time. Therefore, we conclude that composting could stabilize the heavy metals present in the sludge and decrease the risk of soil pollution.

The major components of oxygen scavenger films are polymer, oxidizable compounds, and catalyst. In this study, the oxygen scavenging capacity and oxygen scavenging rate of the oxygen scavenger film in water were determined for evaluating the performance of the films. The results showed that the film composed of polyethylene, 4% sodium erythorbate, and 0.1% EDTA cupric salt had the best oxygen scavenging efficiency. On the 1st and 10th day, the oxygen removed rate of the film was 0.02 and 0.065 mg/cm2/day, respectively, from 300 ml water.

The results showed that the heavy metals in various mediums were mainly Cu and Ni, and those concentrations were, in the descending order, in ditch, tailings, slagheap and cultivated soil. In the tailings and the sludge of the ditch, the concentrations of Ni were obviously higher than those of Cu. Whereas, in the soil and the weathering and atmospheric deposition of the waste slagheap surface, the concentrations of Cu were higher than those of Ni. This means that in the first two mediums, Cu and Ni mainly originated from the tailings, while in the latter two mediums, Cu and Ni mainly came from the atmospheric deposition of airborne particles of the smelting. Cr and Zn were mainly in residual fraction, Cu was mainly in oxidizable and residual fraction.
结果表明:不同区域环境中重金属呈现不同程度累积,其中以Cu、Ni最为显著,含量由高到低依次为尾矿坝排污沟>尾矿坝>废渣堆>农田土壤;尾矿砂和沉积物中重金属分布以Ni含量显著高于Cu含量为特征;而农田土壤和风化物及降尘中重金属分布以Cu含量高于Ni含量为特征,前者Cu、Ni主要来源于尾矿,后者与冶炼烟尘排放有很大关系;样品中除Cr、Zn以残渣态为主外,Cu、Ni、Pb化学形态分布有较大差异,Cu以可氧化态和残渣态为主,Ni以可还原态为主,其次为弱酸提取态,Pb以可还原态为主,其次为残渣态。
