金秋时节,本该秋高气爽却屡屡被挥之不去的雾霾所笼罩。国外有研究表明,PM2.5这种可吸入颗粒物浓度每上升10微克/立方米,呼吸系统疾病发病率就上升3.4%,心血管病发病率上升1.4%,每日总死亡率上升1%。严重的空气污染让现代都市人的心血管系统和呼吸系统越来越脆弱,它们被人形象地称为“玻璃心”“涂鸦肺”。国外很多研究都已经证明,PM2.5这样的细小颗粒会直接深
Fall season, the autumn should have been repeatedly enveloped by the lingering smog. Studies abroad show that for every 10 micrograms / cubic meter increase in the concentration of PM2.5, the incidence of respiratory diseases increases by 3.4%, the incidence of cardiovascular diseases by 1.4% and the total daily mortality rate by 1%. Serious air pollution has made the cardiovascular system and respiratory system of modern urban people increasingly vulnerable. They are vividly called “glass heart” and “graffiti lungs.” Many foreign studies have proven that PM2.5 such small particles will be directly deep
