查询词典 PAHs

EROD and ECOD are both phase I enzymes. There were complicated relations of time-effect and dose-effect between EROD activity and exposure of BaP, TBT or their mixture. Antagonistic interactions occurred after 25 days exposure to the mixure of BaP and TBT. It is fuzzy to merely use EROD activity as biomarker to assess PAHs or TBT pollution.

相解毒酶EROD活性与BaP、TBT及其混合物污染之间存在较为复杂的时间-效应与剂量-效应关系，而且在暴露25 d后，联合作用表现为拮抗作用，仅仅以EROD酶活性指标衡量环境中BaP、TBT或者二者的联合污染水平会出现失真现象。

The DE increases with the increasing of anthracene concentration sorbed in soil. If only Triton X-100 was used, the DE was 4.5% only. The age of MES resulted the decrease of the DE from 91% to 69% for 1day and 7 days, respectively.

另一方面，探讨微乳液再生的可能性，先用等温吸附模式来观察活性碳能否吸附微乳液中的PAHs，之后在实际应用於经土壤脱附实验后的微乳液，并再重复使用。
