1. Could you please help me translate it? Its about the air sampling plan. I dont understand English.
Top 10 points for air sampling. 1. Principle based monitoring methods for microbial populations in air • Passive monitoring • Active sampling 2. Active monitoring requires the use of an air microbial sampler to draw a known amount of air, or through a particle collection device. 3. The most important sources of pollution are air, people, raw materials, and water in any production and operation. 4. Passive monitoring is usually done using a solution board. 5. There are 2 active monitoring devices • Impact 6. It is crucial that the air sampler is properly validated and regularly calibrated to ensure accuracy. 7. The selection of sampling methods depends on the application, and according to 14698-1, it is necessary to consider: • appropriate flow reversal of impact speed • collection accuracy and efficiency • sampling methods that affect the surrounding environment. The selected monitoring location should be based on the risk assessment in the document. 9. The sampling pump or fan for flow rate should be properly calibrated and leak proof certified flow meters. 10. Bacteria and fungal cells and spores in the air can be suspended as "aerosols" in droplets, with very small individual particles suspended and returning to the surface for a long period of time, or larger clumps and total amounts quickly settling to the surface.
