| 摘 要： | 以毒物对青海弧菌Q67 (Vibrio-qinghaiensis sp.-Q67)发光抑制为毒性指标，基于短期微板毒性分析法(S-MTA法)，建立了长期微板毒性分析法(L-MTA法)，测定了吡虫啉(IMI)、抗蚜威(PIR)、啶虫脒(ACE)及敌百虫(DIP)等4种杀虫剂与氯霉素(CHL)、盐酸四环素(TET)、硫酸链霉素(STR)及硫酸巴龙霉素(PAR)等4种抗生素的短期(15 min)毒性和长期(12 h)毒性.采用短期毒性与长期毒性EC50之比(RSL)为指标，表征同一物质的毒性差异. 结果表明:3种杀虫剂(IMI，ACE及PIR)的短期毒性与长期毒性差异不大(其RSL分别为0.84，0.81和1.11)；杀虫剂DIP和2个抗生素(CHL及TET)的短期毒性与长期毒性差异明显(其RSL分别为11.76，9.67及154.38)；另2个抗生素(STR和PAR)只有较强的长期毒性.

| Abstract: | Taking bioluminescence inhibition of toxicants to Vibrio-qinghaiensis sp.-Q67(Q67) as a toxicity indicator,a long-term microplate toxicity analysis (L-MTA) was developed based on short-term microplate toxicity analysis(S-MTA).The short-term(15 min) and long-term(12 h) toxicities of four insecticides -imidacloprid(IMI),pirimicarb(PIR),acetamiprid(ACE),and dipterex(DIP)-and four(antibiotics-)chloramphenicol(CHL),tetracyline hydrochloride(TET),streptomycin sulfate(STR),and paromomycin sulfate(PAR)-were determi... |
