目的通过模拟试验与现场检测,探讨浒苔清运人员的作业环境对人体危害程度。方法通过文献检索、模拟检测、现场检测等方法确定污染物种类,并对其浓度进行检测,评价清运现场工作环境。结果现场工人接触的主要危害因素为NH3、H2S、CO、CO2。挖掘机驾驶室NH3、H2S、CO、CO2的浓度分别为2.27、3.60、4.63、994.00 mg/m3,下风向20 m处分别为<1.00、3.33、2.74、968.00 mg/m3。结论浒苔清运现场人员接触的危害因素浓度皆低于国家职业卫生标准;浒苔清运作业对工人所产生的健康危害较小。
Objective Through the simulation test and on-site testing, explore the hazards of the operating environment of Enteromorpha persimmon personnel on the human body. Methods The types of pollutants were identified through literature search, simulated testing and on-site testing. The concentration of pollutants was tested to evaluate the working environment of Qingyun site. Results The main hazardous factors exposed by workers in the field were NH3, H2S, CO and CO2. The concentrations of NH3, H2S, CO and CO2 in excavator cab were 2.27, 3.60, 4.63 and 994.00 mg / m3, respectively, and those at 20 m downwind were <1.00,3.33 and 2.74,968.00 mg / m3 respectively. Conclusions Enteromorpha excrement contact risk factors concentrations are lower than the national occupational health standards; Enteromorpha ease of transport workers on the health hazards generated by small.
