The effects of biochar/compost for adsorption behaviors of sulfamethoxazole in amended wetland soil.
Environ Sci Pollut Res Int
September 2021
Biochar and compost were two common amendments for the polluted soil. However, few studies were conducted to study the sorption of organic pollutants on combined biochar-compost and the relative adsorption mechanisms in mixed soil. The work had studied the adsorption and desorption behaviors of sulfamethoxazole (SMX) onto wetland soil after amended with biochar and/or compost.

- The study investigated how biochar and compost affect enzyme activity and microbial communities in wetlands polluted with sulfamethoxazole (SMX).
- Different concentrations of biochar and compost were tested, revealing that 1% biochar improved SMX degradation slightly, while 5% reduced it; compost additions generally enhanced degradation efficiency.
- High-throughput sequencing showed that high concentrations of compost and biochar (HCGs) increased bacterial diversity but reduced species richness, while lower concentrations (LCGs) maintained higher richness by supporting more native species.
The combination of biochar and compost has been proven to be effective in heavy metals contaminated wetland soil restoration. However, the influence of different proportions between biochar and compost on immobilization of heavy metals in soil has been less studied up to date. Therefore, we investigated the effect of different ratios of biochar-compost mixtures on availability and speciation distribution of heavy metals (Cd, Zn and Cu) in wetland soil.
