腐烂浒苔清运现场职业卫生检测与评价

Occupational Detection and Evaluation on Workplaces of Clearance and Transport for Rotten Enteromorpha Prolifera

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 To carry out occupational health assessment on the workplaces of rotten Enteromorpha prolifera（E.prolifera） clearance and transport by simulation test and field test.Methods Types of pollutants and their concentrations were confirmed by evaluating the possible health risks through literature search,simulation test and field test.Results The field operation workers were exposed to major risk factors such as NH 3,H 2S,CO and CO 2.Concentrations of various hazardous substances（NH 3,H 2S,CO and CO 2）in excavator cab and 20 meters under the wind direction were 2.27,3.60,4.63, 994.00 mg/m^3 and less than 1.00,3.33,2.74,968.00 mg/m^3,respectively.Conclusion The measured concentrations are lower than the national occupational health standards.Field conditions of cleaning up rotten E.prolifera are safe.
