Toxic Metals in Industrial Wastewaters and Phytoremediation Using Aquatic Macrophytes for Environmental Pollution Control: An Eco-Remedial Approach

  • Mansi Rastogi

Toxic pollutants contaminate water by discharging wastewater generated through municipal, industrial, and landfill site waste, etc. It is emerging as a worldwide problem as it enormously affects human, fauna, and flora health of receiving water. During last few decades, the exponential population growth, productivity variation and consumption rates, and resources exploitation along with rapid industrial and technical development are seen as major contributors that accompany water pollution. Wastewater treatment has been a problem for mankind since the discovery of additional environmental problems caused by wastes discharge into surface waters was done. Though control and prevention technologies are being applied to most of these industrial and municipal sources and there is availability of a wide range of wastewater treatment technologies for restoring and maintaining the biological, chemical, and physical quality of wastewaters, still there is a staggering amount of these agents released into the environment. Another major proven threat to water is heavy metal toxicity with several associated health risks. Although they do not play any big biological role, their trace present in certain form can harm the human body and its proper functioning. This chapter discusses wastewater characteristics, toxic metals added to water, the role of plants in constructed wetlands in removal of various pollutants to remediate the wastewaters from various sources, and constraints and future of constructed wetland as a cleanup technique in wastewater remediation.
