Cadmium Toxicity And Its Phytoremediation A Review

چکیده
Cumulative effect of urbanization, industrialization and population growth is increasing pressure on the limited natural resources. The change in living style has aggravated the problems. Among the diverse environmental problems, the discharge of heavy metals in environment through industrial, agricultural and domestic activities is of great concern. Removal of heavy metal from environment is a challenge as these toxic metals are non-biodegradable and bioaccumulate in living organisms. Sustainable development requires the use of green technologies to treat the wide range of contaminated aquatic and terrestrial habitats. Phytoremediation is an alternative to conventional methods for treating waste compounds. This review discusses the occurrence and toxicity of cadmium, the various remediation techniques with emphasis on phytoremediation of cadmium. Phytoremediation by plants occupying different taxonomic position is discussed. The scientific literature reveals that this technology has tremendous potential to cater for the needs and can be effectively used for environmental protection, sustainability and management.

Biological removal of cadmium from soil by phytoremediation and its impact on growth parameters, photosynthetic pigments, phenol and malondealdehyde content in Vetiveria zizianoides.
Phytoremediation is one of the most widely used methods for removing soil contaminants. In this research, the function of Vetiveria zizianoides to remove cadmium from four different treatments with varying amounts of cadmium chloride contamination (including 0, 20, 40, and 60 mg per liter) was investigated and physiological changes caused by the accumulation of this metal in the plant were moni...

Heavy metal (HM) pollution is a global environmental problem that threatens ecosystem and human health. Cadmium (Cd) pollution is the most prominent HM pollution type because of its high toxicity, strong migration, and the large polluted area globally. Phytoremediation of contaminated soil is frequently practiced because of its cost-effectiveness and operability and because it has no associated...

Cadmium (Cd) is a heavy metal that causes oxidative stress in plants. In this study toxicity effect of Cd on Silybum marianum was investigated. Four treatments of CdCl2 (0, 300, 600, 400 and 900 μM) were evaluated in five replications using complete random design. Results of tolerance stress index severity of Cd stress on plants under various levels of treatments. Shoot dry weight, leaf area, c...
