Phytoremediation Of Soils Contaminated With Metals

Environmental pollution by heavy metals and metalloids has become a severe problem worldwide and soils became increasingly contaminated posing a threat to ecosystems and ultimately to human health. The decision to remediate a soil depends on the present and future value of the soil the cost of remediation the risk posed by the soil and the
