對坑道空氣真菌濃度參考標準(平時)建議的探討

摘要： 目的:根據(jù)不同場所真菌濃度檢測,結合坑道調查情況,提出坑道空氣真菌濃度參考標準(平時)的建議。為坑道及人防工事等特殊環(huán)境的空氣質量評定及衛(wèi)生保障提供參考。方法:對11個不同場所,用撞擊法和沉降法檢測空氣細菌總數(shù)和真菌數(shù),同時檢測微小氣候。結果:11個不同場所空氣細菌總數(shù)撞擊法平均2 062 cfu/m3,沉降法平均21.7 cfu/皿。真菌數(shù)撞擊法平均479 cfu/m3,沉降法平均5.0 cfu/皿。兩種監(jiān)測方法細菌與真菌平均比值為4.3:1。結論:建議坑道空氣真菌濃度參考標準(平時)撞擊法為≤1 000 cfu/m3,沉降法為≤10 cfu/皿。
Objective:To give some advice about the reference standard(peacetime) of the chroma of mycetes in the air in tunnel according to the chroma of mycetes at the different grounds and the instance of tunnel.To adopt the reference of the air quality assess and the sanitation safeguard in tunnel or the guard against work etal special situation.Methods:To count the mycetes and the bacterial number at the 11 different guards in the air in tunnel with the method of knock-on and sedimentation and view the microclimate in tunnel.Results:At the 11 different guards in the air with the method of knock-on the bacterial number average 2 062 cfu/m3,and with the method of sedimentation average 5.0 cfu/utensil.With two kinds of method the bacterial and mycetes number of ratio was 4.3:1.Conclusion:Advising the reference standard which the chroma of mycetes in the air in tunnel with the method of knock-on is 1 000 cfu/m3 and lower,and with the method of sedimentation is 10 cfu/utensil and lower.
