摘要
设计了一款超低温复合季铵盐消毒剂,采用载体定量杀灭试验、毒理学试验和水生生物试验等方法对产品的功效以及对环境的影响进行了系统研究.试验结果表明,在-40℃条件下,复合季铵盐超低温消毒剂对载体布片上的金黄色葡萄球菌和大肠杆菌具有消毒效果,其杀灭对数值均达到或超过3.00,同时消毒剂在急性经口毒性测试中表现为低毒,一次性完整皮肤测试为轻刺激性,对小鼠骨髓嗜多染红细胞微核形成无影响.但其对小球藻的毒性等级为中毒,对大型溞的毒性等级为剧毒,对斑马鱼的毒性等级为低毒.因此在使用超低温复合季铵盐消毒剂的区域,应避免直接将含有消毒剂的污水排入自然水体中,相关的污水需要进行处理以减轻对环境的影响.
Abstract
A ultra-low temperature composite quaternary ammonium salt disinfectant was designed,and the efficacy and environmental impact of the product were systematically studied by means of carrier quantitative killing test,toxicology test and aquatic biological test.The experimental results showed that under the condition of-40℃,the composite quaternary ammonium salt ultra-low temperature disinfectant had a disinfection effect on Staphylococcus aureus and Escherichia coli on the carrier cloth,with killing pair values reaching or exceeding 3.00.The disinfectant showed low toxicity in acute oral toxicity testing,mild irritation to one-time intact skin,and no effect on the formation of micronuclei in mouse bone marrow polychromatic red blood cells.However,its toxicity level to Chlorella vulgaris was moderate toxicity,to Daphnia magnaStraus was severe toxicity,and to Danio rerio was low toxicity.Therefore,in areas where ultra-low temperature composite quaternary ammonium salt disinfectant is used,direct discharge of wastewater containing disinfectant into natural water bodies should be avoided,and relevant wastewater needs to be treated to reduce its impact on the environment.
