赤泥 (RM) 是铝生产的副产品；全球每年生产 70 至 1.2 亿吨。我们对匈牙利Kolontar灾难过程中释放到环境中的RM进行了急性毒性和遗传毒性实验，对广泛用于环境监测的植物进行了分析。我们检测到微核的诱导，这反映了紫露草四分体和葱属根细胞中的染色体损伤，以及污染土壤和渗滤液对根系生长的阻碍。化学分析表明 RM 含有金属，特别是高浓度的钒。后续实验表明钒酸盐会对植物产生影响。这种化合物还会导致人类 DNA 损伤，并且在致癌性研究中获得了积极的结果。由于在其他生产地点的 RM 中也发现了它，我们的研究结果表明，它在环境中的释放是一个全球性问题，应该进行更详细的研究。胶囊摘要我们的研究结果表明，赤泥对植物造成遗传毒性作用，可能是由于残留物中含有高浓度的钒酸盐。
Red mud (RM) is a byproduct of aluminum production; worldwide between 70 and 120 million tons is produced annually. We analyzed RM which was released in the course of the Kolontar disaster in Hungary into the environment in acute and genotoxicity experiments with plants which are widely used for environmental monitoring. We detected induction of micronuclei which reflect chromosomal damage in tetrads ofTradescantiaand in root cells ofAlliumas well as retardation of root growth with contaminated soils and leachates. Chemical analyses showed that RM contains metals, in particular high concentrations of vanadium. Follow-up experiments indicated that vanadate causes the effects in the plants. This compound causes also in humans DNA damage and positive results were obtained in carcinogenicity studies. Since it was found also in RM from other production sites our findings indicate that its release in the environment is a global problem which should be studied in more detail.Capsule abstractOur findings indicate that the red mud causes genotoxic effect in plants probably due to the presence of vanadate which is contained at high concentrations in the residue.
