Abstract:
Objective To explore the concentrations and diameters of the particulates in indoor air of the cosmetic workshops, and provide scientific basis for the testing and evaluation of air cleanliness of the cosmetic workshops. Methods The testing and evaluation on concentrations of the particulates with the diameters of 0.3,0.5,1.0,2.0,3.0,5.0 ?m in indoor air of the cosmetic workshops was carried out among 11 cosmetic manufactures with air filtering and purifying system(air-purified factory) and 13 cosmetic manufactures without air filtering and purifying system but with mechanical ventilation (air-unpurified factory). Results The medians of 0.3～5.0 ?m particulates in air of cosmetic workshops in air-purified factories were significantly lower than those in air-unpurified factories respectively. The concentrations of the particulates in air of cosmetic workshops in air-unpurified factories showed no significant differences compared with those in ambient air.The concentrations of 0.5 and 1.0 ?m particulates showed the significant correlation with those of 0.3?2.0?3.0?5.0 ?m particulates. The concentrations of 2.0?3.0?5.0 ?m particulates showed the significant correlation between each other except for 0.3 ?m particulates. Conclusion The particulates show lower concentration, the air cleanliness doesn't meet the requirement the national standard of 100 000 class in air of cosmetic workshops in air-purified factories. The concentration of 0.5 ?m particulate is suitable for evaluation on air cleanliness in air of cosmetic workshops.
