农历的大年过完了。岁末年初,新的旧的多有交集,使人们焦虑、感慨。雾霾、污染让人们既焦虑、不满又无奈。今天,2月27日,清早的天气预报发布了北京的霾黄色预警,我国中东部的河南、山东等地的大雾预报。2月份北京有多少这样的天气预报我没有统计,估计比上个月不会好多少。上个月的北京有25天霾,只有6个晴天。古代人没有先进的科学仪器能够量出细颗粒物的直径、大小,只是说霾:风雨土也。随着科技的进步,今天的人们知道了PM10、PM2.5,知道了灰霾不光对呼吸系统有伤害,对心脑血管及神经系统都有影响。怪不得有人说,北京这十年肺癌增加60%,空气污染

How many such weather forecasts in Beijing in February I have no statistics, it is estimated not much better than last month. Last month’s Beijing had 25 days of haze, only 6 sunny days. Ancient people do not have advanced scientific instruments to measure the diameter of fine particles, the size, just say haze: stormy soil too. As technology advances, people today know PM10 and PM2.5, knowing that haze affects not only the respiratory system but also cardiovascular and nervous systems. No wonder some people say that in the past 10 years, Beijing’s lung cancer increased by 60% and air pollution
