[Investigation of Dominant Plants and Analysis of Ecological Restoration Potential in Lailishan Tin Tailings].

To investigate the dominant plants in ecological restoration of tin mining areas, field investigations were conducted in a tin tailings area in Lailishan, Yunnan Provence, and 15 dominant plants and corresponding rhizosphere soils were collected. The plant root mycorrhizal infection rate; the copper (Cu), cadmium (Cd), arsenic (As), nickel (Ni), lead (Pb), and tin (Sn) contents; and the chemical properties of the rhizosphere tailings were determined. The transfer and enrichment coefficients of six heavy metals were calculated for each of the 15 plants to comprehensively evaluate the application potential of native plants.

[Acid Mine Wasteland Reclamation by Buchen as a Potential Pioneer Plant].

Ecological reclamation is the major method for the revegetation of acid mine wasteland worldwide. In this study the pH, fertility characteristics, and heavy metal content of soils from Laili Mountain mine wasteland were analyzed. The research also studied the morphological characteristics and the heavy metal in Buchen as well as its resistance to acid, adaptability to soil fertility in abandoned land, and tolerance to heavy metal pollution (e.

[Photo-assisted Degradation of Sulfamethazine by Ferrocene-catalyzed Heterogeneous Fenton-like System].

Antibiotics are acknowledged micropollutants in wastewaters and surface waters. They are of particular concern because they can trigger an increase in resistant bacteria. Therefore, novel and efficient technology for the removal of antibiotics is urgently needed.
