Contamination of ground and surface water, soil, and air by harmful and carcinogenic chemicals is one of the most prevalent problems in the modern industrialized world. Heavy metal toxicity has demonstrated to be paramount hazardous and there are various risks associated with it. In addition, these heavy metals have adverse effects on human health and plant physiology. The field of bioremediation has undergone an impactful revolution in recent years due to an exponential increase in various issues related to soil and water pollution. Bioremediation is an advanced and efficient technology, which involves the use of biological means such as microorganisms and plants to degrade heavy metal contaminants. Among the millions of microbes present in the ecosystem, the highest metal adsorption ability is possessed by species belonging to genus Penicillium, Streptomyces, Bacillus, Rhizopus, Chlorella, Ascophyllum, Sargassum, and Aspergillus. Among different plant species, Allium, Eucalyptus, Helianthus, and Hibiscus are the main heavy metal absorbers. The present review concentrates on the research in the bioremediation of important heavy metals through the use of plants and microbes.
有害和致癌化学物质对地下水、地表水、土壤和空气的污染是现代工业化世界最普遍的问题之一。重金属毒性已被证明是最大的危险,与之相关的存在各种风险。此外,这些重金属对人类健康和植物生理学有不良影响。由于与土壤和水污染有关的各种问题呈指数级增长,生物修复领域近年来发生了重大变革。生物修复是一种先进且高效的技术,它涉及使用微生物和植物等生物手段来降解重金属污染物。在生态系统中存在的数百万种微生物中,具有最高金属吸附能力的是属于青霉属、链霉菌属、芽孢杆菌属、根霉属、小球藻属、海带属、马尾藻属和曲霉属的物种。在不同的植物物种中,葱属、桉树属、向日葵属和芙蓉属是主要的重金属吸收者。本综述重点介绍了通过使用植物和微生物来修复重要重金属的研究。
