Cooking Kills Four Million People a

Cooking Kills Four Million People a Year. Polluted airborne particles （大气悬浮颗粒）kill 7 million people a year, reports the World Health Organization．
That news may not come as a surprise to anyone who has seen images of chimneys in Beijing, Delhi or Mexico．But those factories—or even the jammed roadways of modern cities—are not the biggest killer．Each year, some 4.3 million people die earlier than they should because of polluted air inside their homes, says the WHO．
What's causing the air inside people's homes to be so poisonous that it kills around 11, 000 people a day? Stoves．" Having an open fire in your kitchen is like burning 400 cigarettes an hour．" says Kirk Smith, a professor at the University of California at Berkeley, whose research suggests that household air pollution from cooking killed between 3.5 million and 4 million people in 2013．
Not all stoves cause this kind of harm．The ones Smith's talking about are those that the 3 billion people in the developing world use for heat and cooking, which burn solid fuels such as wood, coal, or crop waste instead of gas．The smoke from those fires produces harmful fine particles and carbon monoxide into homes．Poor ventilation then prevents that smoke from escaping, raising fine particle levels 100 times higher than the limits that the WHO considers acceptable．
Breathing this air day in day out eventually causes a lot of diseases: more than a third of the 4.3 million die of a stroke, while a quarter die of heart disease．And around one-third of annual lung disease deaths worldwide are due to waste from coal stoves．
Exposure tends to be extremely harmful for the people who spend the most time around the fire—usually women and young children．In fact, the WHO reports that household air pollution almost doubles the risk for childhood lung disease．

烹饪 杀死 四 百万人一年   。污染空气中的颗粒物（大气悬浮颗粒）杀死7万人年，报告的世界卫生组织。
，消息可能不来作为一个惊喜，任何人看到图像的烟囱在北京，印度或墨西哥。但这些工厂甚至堵塞巷道现代城市不是最大的杀手。每年，大约4。3万人死早于他们应该因为受污染的空气在自己的家园，说的人。
是什么导致人们的家里的空气是有毒的，它杀死了大约11，000人，一天？炉子。”在你的厨房里有一个开放的火像燃烧的香烟400小时。”Kirk Smith，加州大学伯克利分校教授，的研究表明，家庭空气污染从烹饪杀死3.5万到4万人在2013年。
不是所有的炉子造成这种危害。的史密斯的谈论是那些，这3亿人的发展世界使用取暖和做饭，烧 固体燃料，如木材，煤，或作物废料代替气体。烟从这些火灾产生有害微粒和一氧化碳进入家庭。可怜的 通风 防止，烟雾逸出，提高细 粒子能级的100倍，比的限制，的人认为可以接受。
呼吸空气这一天一天最终会导致很多疾病：超过三分之一的4。3万死于中风，而一季度死于心脏病。每年肺疾病全球死亡人数的三分之一左右，是由于浪费煤炉。
暴露往往是极其有害的人谁花大部分时间围绕的 火灾通常是妇女和儿童。事实上，WHO的报道称，儿童肺 疾病风险家庭空气污染几乎增加了一倍。
