  • 摘要: 采用对苯二甲酸(terephthalic acid，TA)作为羟基自由基(hydroxyl radical，?OH)捕捉剂，利用荧光分光光度法测定了二氧化氯（ClO2）接触后颤蚓体内?OH浓度变化，结合颤蚓灭活率、过氧化氢酶（catalase，CAT）和丙二醛（malondialderhyde，MDA）等指标的测试结果，研究了ClO2对颤蚓成虫的灭活效果及灭活机理。结果表明，ClO2对颤蚓成虫灭活效果显著。当ClO2投加浓度超过0.4 mg/L，可对颤蚓体内?OH产生明显的诱导效应，
    Abstract: The fluctuation of ?OH concentration in T. tubifex exposed to chlorine dioxide was investigated by fluorospectrophotometry using terephthalic acid (TA) as ?OH trapping agent. Catalase (CAT) activity in T. tubifex was quantified after 10 minutes contact with chlorine dioxide. Inactivation effect and lipid peroxidation produce malondialderhyde (MDA) of adult T. tubifex were also studied. Results showed that chlorine dioxide had significant inactivation effect on adult T. tubifex. Significant ?OH inductive effect，which has direct correlation with T. tubifex inactivation effect，was observed when chlorine dioxide level was high than 0.4 mg/L. The fluctuation of CAT indicated that T. tubifex was suffering from oxidative stress and chlorine dioxide damaged the antioxidant defense system of T. tubifex. The variation of MAD showed that chlorine dioxide does not have a significant lipid peroxidation effect on adult T. tubifex and can permeate the worm’s cuticular layer easily. Such results confirmed that one of the inactivation mechanisms of chlorine dioxide is inducing ?OH increase，which results in oxidative stress on adult T. tubifex. Moreover，chlorine dioxide can damage antioxidant defense system of T. tubifex and permeate worm’s cuticular layer easily，which will strengthen its inactivation effect on T. tubifex.
