Vegetation is the principal component of the constructed wetland (CW) systems. To better understand the effect of plant species, the nitrous oxide (N2O) fluxes and bacterial community structure diversity were compared in different CWs planted with six plants. The results showed that N2O fluxes had obvious differences in vegetation systems. The higher risk of N2O emissions was observed in CWs planted...
To study the effect of lead ion on the activity of roots of mung bean seedlings, the experiment adopts five kinds of different concentration lead ion to treat with the mung bean seedling, The results show that the higher concentration lead ion treatment resulted in lower activity of mung bean seedlings roots, and lessen protoplasmic surface charge of roots and the rate of electrophoresis migration...
