| 摘 要： | 微生物的作用可以使土壤中砷转化为气态砷化物而挥发到大气中.研究了不同环境条件对砷污染土壤生物挥发的影响,结果表明:土壤中砷的含量越高,其生物挥发的速率越大,施加生物有机肥能促进砷的生物挥发,同时,砷的生物挥发速率也受到土壤含水量的影响,过高或过低的含水量都不利于土壤中砷生物挥发的进行.

| Abstract: | Arsenic can be transformed into volatilizable arsenic by microorganism in the soil and transferred to atmosphere. The authors focused on the effect of different environmental conditions on the biovolatilization of arsenic, and the results showed that the velocity of biovolatilization increased with the increase of arsenic concentration in the soil. Organic fertilizer could accelerate the biovolatilization of arsenic and the moisture content in the soil also affected the biovolatilization of arsenic. The velocity of biovolatilization became lower if the moisture was high enough or low enough in the soil. |
