Heavy Metals Contaminated Soils and Phytoremediation Strategies in Taiwan

Remediation of heavy metals contaminated soils by ball milling.

In the present work, the use of ball milling reactors for the remediation of lead contaminated soils was investigated. Lead immobilization was achieved without the use of additional reactants but only through the exploitation of weak transformations induced on the treated soil by mechanical loads taking place during collisions among milling media. The degree of metal immobilization was evaluate...

Investigation of Heavy Metals Accumulation in Plants Growing in Contaminated Soils (Case Study: Qazvin Province, Iran)

Environmental pollution with heavy metals is a global disaster that is related tohuman activities. This study was conducted to determine the extent of heavy metalsaccumulation by plant species in Lia industrial city (Qazvin, Iran) and to investigate theremediative capacity of native plant species grown in the contaminated soils. Soil andindustrial wastewater sampling was done radially along tra...

Germination, Growth and Uptake of Heavy Metals in Contaminated Soils (Hordeum bulbosum L.)

The use of metal-accumulating plants to clean the contaminated soil with toxic metals is the most rapidly developing component of phytoremediation as an environmentally friendly technology. Overcoming harsh soil conditions and accelerating the recovery of degraded soils remain a worldwide restoration challenge. This study evaluated the effect of different concentrations of Pb, Zn, Cu and Fe on ...
