以超氧化物歧化酶（SOD），过氧化氢酶（CAT）和过氧化物酶（POD）的比活力变化作为观测指标，进行了脂肪醇聚氧乙烯醚（AE）对大Biao(Pistia stratiotesL.)损伤程度的酶学诊断，结果表明：在17℃下，ρ（AE）0.1mg/L的AE对大Biao的伤害程度极微，ρ（AE）为1．0，10．0mg/L时，大Biao受到较大的伤害，但能逐渐恢复正常生理活动，ρ（AE）为20．0，50．0mg/L时，由于伤害程度大，超出了酶的修复能力，组织逐渐坏死，同时推测，在AE污染下，大Biao的POD是起保护作用的主导酶。ρ

The injuried degree of Pistia stratiotes L. due to pollution of linear alkylethoxylate (AE) was diagnosed by the relative activities of three kinds of enzymes: surperoxide dismutase (SOD), catalase (CAT) and peroxidase (POD). The results showed: Pistia stratiotes L. was injured slightly at ρ (AE) 0.1 mg/L at 17℃; when the concentration of AE was 1.0 or 10.0 mg/L, the injured degree increased, but Pistia stratiotes L. could recover because of these protection enzymes. When the concentration of AE was 20.0 or 50.0 mg/L, Pistia stratiotes L. was...
