Heavy pollution weather refers to the air pollution phenomenon with an air quality index greater than 200, that is, the ambient air quality reaches a serious pollution level or above; heavy pollution weather with PM2.5 as the primary pollutant is commonly known as “smog.” Heavy pollution weather can increase the risk of morbidity and death of respiratory and cardiovascular diseases in the population. In addition, the International Agency for Research on Cancer (IARC) under the World Health Organization has identified particulate matter, one of the main pollutants in the atmosphere, as a human carcinogen.
So, how to deal with heavy pollution weather? Today OLANSI is here to give you tips and teach you a few health protection measures.
- Wear masks scientifically
Everyone must first pay attention to air quality forecasts and keep abreast of local air pollution. When severely polluted weather occurs, everyone should adhere to the principle of “unnecessary not going out” to minimize exposure, especially for sensitive people such as children, the elderly, and patients with respiratory and cardiovascular diseases. If you need to go out, you should wear anti-haze masks to reduce the inhalation of harmful substances. Priority should be given to masks marked with KN95, N95, FFP2 and above. At the same time, you should choose masks that are suitable for your face and have better airtightness; patients with cardiopulmonary diseases should Wear a protective mask with a breathing valve. Children should choose a special mask for children.
- Choose the right air purification equipment
In severely polluted weather, doors and windows should be closed in time, and it is recommended to use a suitable air purification device
Air purifiers have a certain ability to remove one or more pollutants such as particulate matter, gaseous pollutants, and microorganisms in the indoor air. The most commonly used air purifiers in the market are physical (usually suitable for removing suspended particulates), chemical type (for removing harmful gases), ionized type (for deodorizing and killing bacteria); “clean air volume” (CADR value) and “cumulative purification capacity” (CCM value) are two main indicators for judging the quality of air purifiers. The CADR value reflects the purification capacity per hour (the larger the CARD value, the stronger the purification capacity), and the CCM value Reflects the continuity of the purification ability (the larger the CCM value, the longer the replacement or cleaning cycle of purification parts), so you can choose an air purifier that meets the standards according to the pollutants that the family wants to purify and refer to these two indicators.
Key points: When using an air purifier, close doors and windows, open windows at an appropriate time for indoor and outdoor air exchange (because air purifiers circulate and purify indoor air, indoor CO2 concentration will increase), and regularly replace or clean purification components.
