12月2日，空气治理专家Sam先生，来到张家港给新纽顿的幼教工作者和学生家长们进行了一场足以改变他们命运的讲座。为什么这么说？因为空气质量事关每个人的生命健康，对于孩子来说，更是他们茁壮成长的根基，所以这也是新纽顿一直以来都尤为重视的工作内容。
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!
在讲座现场，我们注意到，Sam先生到哪都随身携带着两样神器：3M口罩和PM2.5检测仪。Sam告诉我们，在从苏州来张家港的路上，他检测了张家港新纽顿幼儿园接待车内的PM2.5指数，为大于150。他要求司机开启内循环，风力开到最大后，5分钟之内，指数降到35。Sam强调，由于尾气、刹车粉尘等原因，道路上的PM2.5指数比住宅区要高很多，在空气不良的道路上行驶，务必开启高风档内循环模式。并且要确保车内的滤网是有定期维护的。
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.
作为一个在中国生活了12年的美国人，又是专业从事低能耗下的空气治理专家，Sam由衷感慨：选择留在中国是他的决定，但肯定要对自己的家人负责。室外的空气个人没法掌控，因此一定要管理好室内的空气质量。孩子一天24个小时，大约有90%的时间是在室内的，可见管理好室内空气的重要性。
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.
这也是新纽顿一直以来非常关注的问题，由于教室的人员密度大，空气流动差，教室内二氧化碳浓度过高，空气质量堪忧，多数情况比室外要污浊。关闭门窗后，PM2.5、粉尘、甲醛等污染物质和病毒、细菌等，都会严重影响学生和老师们的健康，头晕胸闷、乏力烦躁、记忆力下降等不适症状纷至沓来。
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.
新纽顿认为，孩子的健康不能等待，为避免孩子遭受日益严峻的空气污染，改善教室空气质量，园方切身为孩子的健康着想，耗巨资打造“新风系统”，真正实现无霾校区。
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向老师和家长们解释了新风系统的工作原理。新风系统作为一种新型室内通风排气设备，属于开放式的循环系统。该系统利用专用设备向室内侧送新风，再从另一侧由专用设备向室外排出，在室内形成“新风流动场”。在送风的同时，新风系统不间断地为室内输送富含氧气的空气，并通过高于90%的过滤率不断重复地过滤室内PM2.5以净化空气，保证室内空气品质达到健康标准以上，最后通过强制排风系统将室内污染空气排出室外，使孩子们在室内也可以呼吸到新鲜、干净、高品质的空气，并可由家长在手机客户端对此进行实时监测。
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.
不仅保证了孩子们的健康成长，也让家长们能够安心，新风系统将为孩子们的身心健康保驾护航。
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.
3、 关闭门窗（甚至窗帘）。最好能保持室内压力为正压，尽量阻止室外污染空气从门缝、窗缝、墙缝漏进来。脱排油烟机、排气扇都会加剧室内负压。强烈建议，启用脱排油烟机时，关闭厨房的门，打开厨房的窗户。烹饪也会产生PM2.5颗粒物，脱排油烟机的定期清洁非常重要。
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.
家长和中教的讲座结束后，Sam和幼儿园外籍教师做了座谈。在深入了解了新纽顿新风系统工作的原理和使用方法后，外教们打消了对中国空气污染的焦虑。
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还跟大家探讨了雾霾的缘由，以及如何帮助地球减排、减负。大家达成共识，从我做起：节省能源、垃圾分类、珍惜食物、环保出行、管理好各自班级的室内空气。做为教育工作者，为孩子做好榜样！
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.
这场讲座，是张家港新纽顿幼儿园环保系列工作的一个开头，我们期待着和家长分享更多的环保理念，听取家长对于家园共建的声音。为了我们的子孙后代、为了我们的地球，我们不能等待！
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!
