| 中文摘要 |
| 为了探讨SR菌应用于净化回收电镀废水重金属工艺的安全性,通过11项试验和调查,研究了SR菌的毒力、毒性、致毒性、感染性和致敏性,SR菌在机体内的转归,人接触SR菌后的反应,SR菌对植物生长和遗传的影响。结果表明SR菌的毒力、毒性、致毒性都在无毒范围;不致传染病;不致皮肤过敏;SR菌对植物的生长和遗传无不良影响;进入胃肠道的SR菌6h入血液循环,24h由尿、粪排出,体内的SR菌在7d左右被机体解体。通过以上研究证实SR菌在治理重金属废水工艺中应用是安全的。 |
| 英文摘要 |
| In order to know the safety of using SR-bacteria in industry,the safety of SR-bac.were studied with five species of animals,two species of plants and human through eleven experiments based on the theory and methods of toxicity,microbiology and electro-microscope-technology.The main points are toxicity,pathogenicity and the changes of SR-bac.in different times after entering the body.Experimental results showed that the virulence,toxicity and toxigenecity of SR-bac.are within nontoxic range;SR-bac.were nonpathogenetic and had no sensitization;SR-bac.didn't show the effects on growth and genetic toxicity of plants;SR-bac.enter the blood within 6 hours after oral intubation and are excreted from urine and dung after 24 hours,and finally are destroyed in the blood after 7-9 days.The SR-bac.are safe in industry application of purifying heavy metals in the waste water. |
