Abstract

Objective: Evaluate the application effect of the intelligent air purifier through the analysis of monitoring results before and after the pathology department air purification. Method: Make 30 days of real time, dynamic monitoring to the air quality of the pathology department conventional technical support division before and after purification by “eagle eye” environment monitor, record 100 times of monitoring data of the work time and make analysis. Result: The concentration of formaldehyde, TVOC, CO2 and CO before purification are 1.21 ± 0.80 mg/m3, 0.21 ± 0.46 mg/m3, 0.06 ± 0.01%, 3.28 ± 1.49 mg/m3, while after purification which respectively are 0.06 ± 0.01 mg/m3, 0.00 ± 0.00 mg/m3, 0.06 ± 0.01%, 0.71 ± 0.33 mg/m3. Conclusion: Through the real time monitoring to the air quality of the pathology department after using the intelligent air purifier, we find that the concentration of formaldehyde, TVOC,CO and PM 2.5, PM 10 are markedly reduced (P<0.05), those were in the safety level, it can make sure the staff health by using the air purifier.

Highlights

ResultThe concentration of formaldehyde, total volatile organic compounds (TVOC), CO2 and carbon monoxide (CO) before purification are 1.21 ± 0.80 mg/m3, 0.21 ± 0.46 mg/m3, 0.06 ± 0.01%, 3.28 ± 1.49 mg/m3, while after purification which respectively are 0.06 ± 0.01 mg/m3, 0.00 ± 0.00 mg/m3, 0.06 ± 0.01%, 0.71 ± 0.33 mg/m3
Air pollution generally means a phenomenon that certain substances caused by human activity or natural process get into the atmosphere, after reaching enough concentration and enough time, endanger the human comfort, health and welfare or the environment
In pathological science laboratory, which is widely used in fixing and preservation of specimens? Formaldehyde is great harm to human body, which can be absorbed through respiratory tract, digestive tract and skin

Summary

Result

After 100 times of measurement, by using the intelligent air purifier, the indoor CO2 concentration before and after purification are all 0.06 ± 0.01(%), with no obvious difference. After 100 times of measurement, by using the intelligent air purifier, the indoor PM 2.5 and PM 10 concentration decrease have significant difference (P
