Phytoremdiation Species And Their Modification Under By Weed Varying Climatic Condition: A Changing Scenario

The major reasons for environmental contamination are population explosion, increase in industrial and other urban activities. One of the consequent effect of these activities is heavy metal pollution. It is one of the serious issue to be discussed by the scientists and academicians that how to solve this problem to protect the environment. As heavy metals are non-biodegradable so they require effective cleanup technology. Most of the traditional methods such as excavation, solidification and burial are very costly or they simply involve the isolation of the metals from contaminated sites. Among different technologies, phytoremediation is best approach for removing metal contamination from environment. It involves plants to remove, detoxify or immobilize metals from environment. Weed plants are found to be play very important role in metal remediation. They get affected by climatic variation which is also a consequent effect of environmental pollution. The physiology of plants as well as physiochemical properties of soil gets affected by varying climatic condition. Therefore, the present review gives the information on metal remediation processes and how these process particularly phytoremediation by weed plants get affected by climatic changes.
