On November 2nd, Mr. Sam, a specialist in air-purification and odor removal, came to Zhangjiagang Newton to deliver an important lecture about air pollution and control. Air quality is vital to children’s health and growth. From the very beginning, Newton put a lot of emphasis on indoor air control, which will become a long-term career and we will never stop!
For Sam, the two of the very useful and important protections are 3M masks and PM 2.5 detector. In the lecture, Sam told us he tested the PM 2.5 index in the reception car and it is greater than 150. He also asked the driver to turn on the internal circulating with the strongest wind, then within 5 minutes, the index is lowed to 35. Sam emphasized that vehicle exhaust, brake dust and other pollution make the PM 2.5 index much higher than it in the living community. When we drive on roads and streets where air quality is bad, we must turn on internal circulating and make sure the filter is regularly maintained.
下午讲座现场的PM2.5指数为室外指数的1/6，现场使用的是一台“奥斯丁”空气净化器和两台“小米”空气净化器，均开启为高风档。In the lecture room, the PM 2.5 index is one sixth of the outdoor PM 2.5 index, with the “Austin”air purifier and “Mi”air purifier on with strong wind. Sam在讲座中提到，在中国有一个普遍的观点是：人体可以适应PM2.5！×这种观点是非常不科学的，甚至非常危险。pm2.5和一般的粉尘颗粒不同，pm2.5中含有大量的重金属颗粒物，它不易被人体鼻腔的纤毛、粘膜过滤，而是会直接通过肺部的交换甚至进到人体的血液内。PM2.5的易感人群为儿童、孕妇、老人，可能会诱发和加剧心血管和血液疾病，可能会影响儿童正常生长发育，甚至会缩短正常人的生命。
In the lecture, Sam mentioned that in China, people thought that human bodies can adapt to PM 2.5, which is a very dangerous thought. Because PM 2.5 contains a lot of heavy metal particulate matter which will not filtered by nostril hair but will go directly to inner body to lungs and even blood, and cause cardiovascular disease and blood disease. The most susceptible are children, pregnant women, and the elders.
As an American specialist in air-purification and odor removal, who has been living in China for 12 years, Sam said that to choose to live in China is his own decision, but he also need to be responsible for his family’s health. The outdoor air quality is out of a person’s control, what we can do is to try our best to manage the indoor air quality. Our children spend most of the time indoors, so it is very important to provide fresh air in every classroom.
Newton also realized this problem and has been putting a lot of effort and energy in improving this situation. The classroom density is big, and air quality is not very good. When we close the door and window, PM 2.5, dust, HCHO, virus, bacteria and other harmful materials will affect seriously children and teachers’ health, sometimes will cause dizziness, tiredness, memory decay, etc.
We think that children’s health is important. To prevent our children from being affected by air pollution and to improve the classroom quality, we make a huge investment in the “fresh air system” and install it in every classroom. The kindergartens in Newton become schools with no haze.
Sam explained the working principle of the “fresh air system”. It is an equipment of creating fresh air indoors and open loop system. It will create fresh air indoors in one end and discharge the bad air in another end, creating a “fresh air flow field”. Then children can have fresh, clean, high quality air, and parents can also monitor the air by mobile phone.
This will not only make children children breathe in fresh air, but also parents are very satisfied with the “fresh air system”.
讲座中，Sam还跟大家分享了一系列应对空气污染的宝贵经验： In the lecture, Sam shared with everyone the experiences of dealing with air pollution:
1、 在室外戴好口罩。不要过分追求防尘效果，但是要坚持戴。推荐性价比、佩戴舒适度适中的的3M口罩。口罩要经常更换。wear masks indoors. Remember to put on masks everyday when air quality is bad. The 3M masks are very good in price and it is very comfortable when we wear. Also we need to change the masks often.
2、 切勿在空气污染的情况下运动，否则会吸入比静态状态下多很多的颗粒物。Don’t have big movements when air quality is heavy, otherwise we will breathe in more particulate than in static state.
Close door and window even curtain. Keep the inner pressure positive, this will prevent the polluted air coming into indoor through door crack, window crack, and wall crack. The range hood, ventilator fans will make the pressure negative. So it is strongly recommended that when we turn on the range hood, we need to close the kitchen door, open the kitchen window. Cooking can also create PM 2.5, so it is important that we can clean the range hood regularly.
4、 使用空气净化设备。不要迷信高价进口品牌。空气净化主要看四点：风量、滤网的面积、滤网的等级和相对应的室内面积。国产的小米、长虹等低价品牌都被证明能快速有效吸附PM2.5颗粒物。Use air purifier. Don’t think that the more expensive, the more useful. The four factors that determine the air purifier quality are: wind power, the filter size, the filter degree, the indoor area. Cheap brands that are“Made in China”are Changho and Mi are proved to be able to adsorb PM 2.5.
5、 维护您的空气净化设备：定期清洁初效滤网，及时更换HEPA滤网。Maintain air purifier regularly: clean filters regularly and change HEPA filter.
6、 建议购买一台空气检测设备，实时采集室内外空气质量数值。It is suggested to buy air detector and find the AQI.
7、 建议在手机上下载播报室外空气质量的APP。 It is suggested that we can install an air quality monitor APP.
8、 建议和家里老人一起学习和研究空气质量对人体的危害，和老人一起学习管理室内空气质量。. Learn the bad effects of air pollution and learn to manage indoor air quality together with grandparents.
After the lecture with parents and Chinese teacher, Sam also had a discussion with the foreign teachers. After learning deeply of the working principles and methods, the foreign teachers are less worried about the air pollution in China.
Sam also discussed what causes haze, how to help our earth become green. We all agree that we save energy, classify garbage, save food, green transport, manage the classroom air quality. We can set a good example for children! Role model is important. Children can learn from us.
This lecture opens the prelude of Zhangjiagang Newton environment protection career. We hope that we can share more environment ideas with our parents and all collect back parents’ ideas. For our children, for our environment, for our mother earth, we can’t wait to take measures to improve!
