The General Office of the Chinese National Health Commission announced
“Guidelines for Health Protection of Air Pollution (Haze) Population”
Guidelines suggest:
Primary and secondary schools and kindergartens are equipped with air purifiers.
What’s Haze?
Haze is a weather phenomenon in which a large number of atmospheric aerosol particles with a particle size of several microns or less make the horizontal visibility less than 10.0 km and the air is generally turbid.
What’s the influence of haze?
The guideline proposes that the direct impact of haze pollution on health is mainly irritating symptoms and acute effects, mainly manifested as:
Eye and throat irritation, cough, dyspnea, nasal congestion, runny nose, rash, etc., symptoms of upper respiratory tract infection, asthma, conjunctivitis, bronchitis and other diseases are intensified Increased hospital admissions, etc.
At the same time, the appearance of haze will also weaken ultraviolet radiation, affect the synthesis of vitamin D in the human body, lead to a high incidence of rickets in children, and enhance the activity of infectious bacteria in the air. Haze will also affect people’s mental health, causing people to have negative emotions such as depression and pessimism.
Three Types of Key Groups for Haze Pollution Protection
The first is sensitive groups such as children, the elderly, and pregnant women;
The second is patients with cardiopulmonary diseases, such as patients with coronary heart disease, heart failure, asthma or chronic obstructive pulmonary disease;
The third is people who work outdoors for a long time, such as traffic police, sanitation workers, construction workers, etc.
The guidelines also propose that public places with many people indoors should be ventilated in a timely manner according to the level of air pollution, and supplemented with fresh air that filters and removes fine particles. Kindergartens, primary and secondary schools, offices, indoor fitness places and other indoor places are recommended to be equipped with air purifiers to reduce PM2.5 concentrations as much as possible; when conditions permit, air ventilation system devices can be used to introduce fresh air to prevent excessive carbon dioxide concentrations. In severe haze weather, kindergartens and schools should suspend outdoor group activities and try to avoid indoor sports.
Protective Measures and Skills for The Key Groups
for example–
In mild haze weather, children, the elderly, pregnant women and patients with cardiopulmonary diseases should reduce going out and exercise outdoors, exercise more indoors or adjust exercise time, and try to avoid going out for exercise during peak haze pollution;
In moderate haze weather, children, the elderly, pregnant women and patients with cardiopulmonary diseases should avoid going out and exercising outdoors;·
In severe haze weather, children, the elderly, pregnant women and patients with cardiopulmonary diseases should stay indoors; When key groups of people must go out, they should wear protective masks equipped with breathing valves, and should consult a professional doctor before wearing masks; Outdoor workers should wear masks with anti-haze function. When you get home, you should change your clothes, wash your face, nose and exposed skin in time.
Xiamen Municipal Education Bureau formulated and announced
“Emergency Plan for Heavy Air Pollution Prevention of Xiamen Municipal Education Bureau”
Based on the plan, to sum up as belows:
151≤AQI≤200
Xiamen primary and secondary schools and kindergartens will reduce outdoor activities
201≤AQI≤300
Even cultural activities should be reduced
AQI>300
Xiamen primary and secondary schools and kindergartens can suspend classes!
The health of school kids students cannot be ignored, and we need to pay attention to it. Equipping with an air purifier can greatly reduce the problems caused by air pollution and provide a healthy environment for students to study with peace of mind.
