In order to investigate the toxicity-resistance of eighteen Chinese native plants in lead (Pb)-zinc (Zn) mine tailings, we categorized their resistance to Pb and Zn, and tested their potential for phytoremediation effectiveness of Pb and Zn. Fourteen woody plant species belonging to 12 families, and 4 herbaceous species belonging to 4 families, were grown in pots with mixtures of 100% tailing +0% peat (CK), 90% tailing +10% peat (A1), and 80% tailing + 20% peat (A2), respectively. Plant height and biomass, chlorophyll content, and Pb and Zn contents of non-rhizosphere spoil mixtures and plant tissues were measured. Fifteen of the plants grew in all three spoil mixtures. Both A1 and A2 had higher plant height and biomass increment and chlorophyll contents than CK. The content of Pb and Zn in plant shoots and roots was CK > A1 > A2. The value of BCF less than 0.1, compared to 1, was a more precise classification basis for plants excluding metals. Screening for Pb and Zn resistant plants and their bioremediation potential produced the following candidate species: Sapium sebiferum, Salix matsudana, Hibiscus cannabinus, Corchorus capsularis, Ricinus communis, and Populus nigra. These species were highly Pb and Zn tolerant species, with notable growth characteristics and capacities to bioaccumulate Pb and Zn from the mine tailings. Compared to CK, the removal of Pb and Zn from non-rhizosphere spoil increased by an average of 9.64% and 9.6%, respectively in A1, but decreased in A2. The results indicated candidate species and 10% peat addition in the tailing were significant in phytoremediation of Pb and Zn regarding environmental safety.

Endogenous or exogenous substances which inhibit the normal growth of human and animal cells or micro-organisms, as distinguished from those affecting plant growth (= PLANT GROWTH REGULATORS).
A furanyl adenine found in PLANTS and FUNGI. It has plant growth regulation effects.
A family of transcription factors that are induced by GROWTH FACTORS and contain a highly conserved DNA-binding domain composed of three ZINC FINGER MOTIFS.
A nuclear protein and tumor suppressor that contains a C-terminal PHD ZINC FINGER. It is expressed in different isoforms in various tissues and interacts with TUMOR SUPPRESSOR PROTEIN P53 to negatively regulate cell growth. Reduced expression and chromosomal rearrangements of the ING1 gene are associated with different cancers including HEAD AND NECK NEOPLASMS.
A sympathomimetic agent with mainly indirect effects on adrenergic receptors. It is used to maintain blood pressure in hypotensive states, for example, following spinal anesthesia. Although the central stimulant effects of mephentermine are much less than those of amphetamine, its use may lead to amphetamine-type dependence.
