为了解环卫作业对从业人员的影响，对广州市９７１例环卫工人健康状况进行调查分析，发现上呼吸道粘膜刺激征候阳性率、心电图功能异常率、甘油三酯超标率、抗“Ｏ”试验阳性率、乙肝病毒抗原（ＨＢｓＡｇ）阳性率等指标明显高于对照组。环卫职工性别、年龄、工种是某些评价指标的影响因素，经统计学分析比较有显著性意义，提示与环卫作业条件及环境因素对其影响有关。
In order to understand the impact of sanitation operations on employees, the health status of 971 sanitation workers in Guangzhou City was investigated. The positive rates of upper respiratory tract irritation signs, abnormal electrocardiograms, abnormal triglyceride rates, and positive rates of anti-O tests were found.

Sanitation workers’ sex, age and type of work are the influencing factors of some evaluation indicators. Statistical analysis shows that there are significant meanings, and the reminder is related to environmental conditions and environmental factors.
