汶川映秀镇灾后终末消毒效果评估
摘要
目的评估映秀镇灾后终末消毒效果和消杀药物残留对当地环境所造成的影响。方法采用现场感官检查、采样检测等方法,对消杀处理后的环境卫生、空气微生物含量、蚊蝇密度、鼠密度、土壤中残留消杀药物等指标进行了评估。结果镇内空气质量较好,空气中微生物含量明显低于镇外居民安居点,无明显异味。蚊、蝇、鼠密度均低于国家环境标准;土壤中未检测到余氯和杀虫药残留。镇周8个水源的水质全部达到国家生活饮用水水源水质二级标准。结论汶川地震重灾区在开展了大规模消毒、杀虫和灭鼠之后,废墟内多数部位没有异常气味;空气中微生物和蚊、蝇、鼠密度均控制在国家标准之内,环境中无消杀药物残留。
Objective To evaluate Yingxiu town terminal disinfection efficacy and effect of disinfectant and pesticide residues on the local environment after the disaster.Methods On-the-spot sensory inspection,sampling and other testing methods were used to assess the indexes such as environmental sanitation,air microbial content,mosquito,fly and rodent density,disinfectant and pesticide residues in the soil.Results The air quality of the town was good and air microbial content was significantly lower than that in resident settlements outside the town.There was no abnormal smell.The densities of mosquitoes,flies and rodents were lower than those specified in the national environmental standards.There was no residual chlorine and pesticide in soil.The water quality of eight water sources met the national drinking water quality second-grade standards.Conclusion After large-scale disinfection,disinsection and deratization in Wenchuan earthquake hardest hit area,there was no unusual smell inside most ruins of the town.The micro-organism,mosquito and fly densities in air and the rodent density were all controlled within national standards.There was no disinfectant and pesticide residues in the environment.
