Soil salinization, a growing problem in arid and semi-arid areas, significantly influences the ecological dynamics and processes in wetland ecosystems. To fully examine the physiological responses with the aim of wetland protection and management, a laboratory simulation experiment was conducted to study the effects of soil salinization on the growth of C. schmidtii tussocks. Plant height and leaf...
Indoor experiments were performed to determine the accumulation, subcellular distribution, and chemical forms of Cd at five S levels in Hydrilla verticillata. The Cd content increased from 1.229 mg/g to 3.329 mg/g in leaves, and decreased from 2.794 mg/g to 1.023 mg/g in roots, respectively. Excess S supply stimulated Cd assimilation in leaves as Cd accumulation was inhibited in roots. The Cd content...
We used the “space for time substitution” method to test the effects of reclamation history on evolution processes of soil properties and heavy metal concentrations. A total of 129 surface soil samples were collected in a reclamation zone of the Liaohe River Delta, which was divided into three reclaimed zones (1930s, 1960s, and 1990s), marsh, and intertidal flats. Soil metals (Fe, Mn, Cd, Cr, Cu,...
This paper evaluates the feasibility and stability of the construction of a super-large-scale filtered tailings storage facility on coal-mining subsidence land. Properties of the coal gangue were analyzed by laboratory tests and change laws of the land subsidence were observed in the field. Comparisons of slope stability between the super large-scale filtered tailings storage facility and conventional...
Constructed wetlands (CWs) are regarded as a risk mitigation strategy for alleviating the risks associated with agricultural runoff that contains pesticides. We investigated the partitioning pattern of wastewater-borne chlorpyrifos, a widely used organophosphorus pesticide, in non-vegetated and vegetated CWs. Removal rates of chlorpyrifos calculated from inflow and outflow concentrations ranged from...
Coal gasification coarse cinder (CGCC) is the main waste in the coal gasification industry, containing low calorific value but high heavy metal residuals. To achieve environmental toxicity stabilization and waste recycling, we developed a manufacturing method of multiple-functional ceramsite from CGCC by pelletizing and sintering. By altering key parameters during the manufacturing process (including...
Seismic waves travel faster in rock stratum and have greater environmental responses. This paper analyzed the transmission regulation, vibration frequency, and amplitude attenuation characteristics of waves in layered elastic medium. Also, impacts of the elastic modulus of homogeneous medium, subway tunnel depth, and other factors on the environmental response in the runtime were investigated. Based...
Antimony (Sb) pollution in Sb mining areas has been of growing environmental concern. However, limited information is available on environmental behavior and biogeochemical process of Sb. In the present study, complexation of Sb(III) with extracellular polymeric substances (EPS) from cyanobacterium Synechocystis sp. was investigated using excitation-emission matrix (EEM) fluorescence spectroscopy...
Antimony (Sb) pollution has been of growing environmental concern. Little information is available on biosorption of Sb. In the present study, biosorption behavior and mechanisms of Sb(III) to the cyanobacterium Synechocystis sp. cells were investigated by batch experiments and FTIR analysis. Our study shows that Synechocystis sp. cells are a good adsorbent for Sb(III) with a sorption capacity of...
Maize (Zea mays) growing in soil watered with Sb mine drainage (SMD) could accumulate Sb and transferred Sb from roots to shoots. The photosynthetic processes in the leaves were clearly inhibited by SMD. Chlorophyll synthesis was inhibited. Photosystem II (PSII) was sensitive to SMD. PSII activity (FV/FM and PIABS) was reduced due to SMD. Irrigation with SMD resulted in an increase in the proportion...
