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.

2. Water Utilization, Introduction, and How to Save Water (English Version)

Water conservationWater conservation, saying that through administrative, technical, economic and other management tools to strengthen management of water, adjust the structure of water, improving water

, a planned water to prevent water wastage, use advanced science and technology to establish a scientific water system, the effective use of water resources, protection Water resources, to sustainable economic and social development needs.Water-saving propagandistsWater conservation is everyone "s responsibility. Only we all pay attention to water conservation, Shuihuang to stay away from our left, life will be stable and harmonious environment will be beautiful comfort.

Therefore, in daily life have some small sense of saving water is very necessary.First, brush their teethWaste: uninterrupted water.Water-saving: Koubei to water.Second, laundryWaste: washing machines uninterrupted waterside Chonglin side note, the laundry drainage way.Water-saving: on washing clothes, laundry to reduce the number of small pieces, a small amount of clothing to promote rear; detergent running appropriate.3, BathWaste: too long uninterrupted water Chonglin; bath when too much water and overflow, or water side of open water Cypriot side.Water-saving: intermittent water shower, when Cuoxi timely clearance of water, avoid too long Chonglin.
