摘　　要：大气飘尘中的重金属直接影响着生态环境质量,尤其是颗粒物含量过高被人体吸入后,可能诱发心脏病、肺病、呼吸道疾病等,在生态环境保护过程中需全面重视。利用超声波震荡处理,制取滤膜中飘尘微粒,在电感耦合等离子体质谱试验中,测定大气飘尘中铅、镉、锰、锌含量,其操作简单,准确度高,精密度好,实用效益显著。Heavy metals in airborne dust directly affect the quality of the ecological environment, especially if the particulate matter content is too high and inhaled by the human body, it may induce heart disease, lung disease,respiratory disease and so on. In the research, ultrasonic vibration treatment was used to prepare the dust particles in the filter membrane. In the inductively coupled plasma mass spectrometry test, the content of lead, cadmium,manganese and zinc in the atmospheric dust was determined. The operation is simple, the accuracy is high, the precision is good, and it is practical The benefits are significant.
