二恶英具有“三致”毒性,是一种迄今为止发现过的最具致癌潜力的物质,即使在浓度很低的环境中人体也会发生诸多病变,国际癌症研究中心早已将其列入人类一级致癌物。对于钢铁行业,其主要产生于烧结和电炉炼钢两大生产工序;结合二恶英的性质及产生机理,对烧结、电炉炼钢、高炉炼铁等生产工序二恶英的产生情况进行了简要介绍。 Dioxin has the “triple toxicity” and is the most carcinogenic potential substance discovered so far. Even in very low concentrations, the human body undergoes many pathological changes. The IARC has long listed it Into the human level carcinogens. For the steel industry, it mainly comes from the two major production processes of sintering and EAF. Combining with the properties and production mechanism of dioxin, the production of dioxins in sintering, EAF and BF Introduction.
