Over centuries, human industrial, mining and military activities as well as farming and waste practices have contaminated large areas of developed countries with high concentrations of heavy metals and organic pollutants. In addition to their negative effects on ecosystems and other natural resources, these sites pose a great danger to public health, because pollutants can enter food through agricultural products or leach into drinking water. A number of microalgae species or plant species are efficient in removing toxicants from wastewater. Phycoremediation is the technology that uses plants to remove pollutants from the environment. Phytoremediation uses wild or genetically modified plants (GMPs) to extract a wide range of heavy metals and organic pollutants from the water. Plants accumulate heavy metals from contaminated soil and water. These plants can be grown and harvested economically to clean up the environment, leaving only residual levels of pollutants. The various processes by which phytoremediation takes place are phytoextraction, rhizofiltration, phytostabilization and phytovolatilization. The expenditure of phytoextraction is moderately inexpensive and contaminants can be separated permanently.
