TLDR
The results indicate the feasibility of using this autochthonous willow together with both EDTA and ethyl lactate for the simultaneous removal of PHE and Cd from soils.Abstract:
To assess the phytoremediation potential of an autochthonous willow (Salix × aureo-pendula CL 'J1011') for phenanthrene (PHE)-contaminated soils and PHE-cadmium (PHE-Cd) co-contaminated soils, we conducted field experiments in the lower reaches of the Yangtze River, China. Ethylenediaminetetraacetic acid (EDTA) and ethyl lactate were tested for individual and combined effects on the phytoremediation efficiency. For PHE-contaminated soils, willow plus ethyl lactate resulted in significant removal of PHE from soils after 45 days, and the PHE concentration in the shoots was significantly higher with than without ethyl lactate. For PHE-Cd co-contaminated soils, both willow plus EDTA and willow plus EDTA and ethyl lactate led to a significant decrease in the concentrations of PHE and Cd in the soils after 45 days, whereas willow alone did not. The PHE and Cd concentrations in the willow shoots were significantly enhanced in the presence of EDTA alone and with ethyl lactate, except for the PHE concentra...read more

Phytoremediation for co-contaminated soils of benzo[a]pyrene (B[a]P) and heavy metals using ornamental plant Tagetes patula.
TL;DR: Results showed that the low concentration of B[a]P (≤10 mg kg(-1) could facilitate plant growth and resulted in an increase in biomass at the rate of 10.0-49.7% relative to the control, and T. patula might be useful for phytoremediation of B,[a]p and B[ a]P-Cd contaminated sites.
