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.
