The air inside can be worse
- We spend most of our lives indoors.
- Indoor air can be more polluted than the air outside.
- Pollutants come from stoves, materials, and the ground.
- With windows shut, they build up and cannot escape.
里面的空气可能更糟
- 我们一生大部分时间在室内度过。
- 室内空气可能比外面的空气更污染。
- 污染物来自炉灶、材料和地面。
- 窗户关着,它们积累起来无法逃逸。
From burning indoors
- Carbon monoxide 一氧化碳 comes from stoves and heaters.
- It is invisible and odourless — but deadly.
- Tobacco smoke fills a room with harmful particles.
- Cooking and heating fires add smoke, especially in poorer homes.
来自室内燃烧
- 一氧化碳(carbon monoxide)来自炉灶和加热器。
- 它看不见、无味——但致命。
- 烟草烟雾用有害颗粒充满一个房间。
- 做饭和取暖的火添加烟雾,尤其在较穷的家里。
Carbon monoxide is especially dangerous indoors because it… · 一氧化碳在室内特别危险,因为它……
Carbon monoxide cannot be seen or smelled, so it can build up and kill without warning. · 一氧化碳看不见也闻不到,所以它能在没有警告的情况下积累并致命。
From the ground and materials
- Radon 氡 is a radioactive gas that seeps up from rock.
- It collects in basements and can cause lung cancer.
- Asbestos 石棉 fibres come from old insulation.
- New furniture, paint, and carpet give off chemical vapours.
来自地面和材料
- 氡(radon)是一种放射性气体,从岩石渗上来。
- 它聚集在地下室里,能造成肺癌。
- 石棉(asbestos)纤维来自旧的隔热材料。
- 新家具、油漆和地毯放出化学蒸气。
Where does each indoor pollutant come from? · 每种室内污染物来自哪里?
Sort each indoor pollutant by whether it comes from burning or from materials and the ground. · 按照每种室内污染物来自燃烧还是来自材料和地面,给它们分类。
Radon is a pollutant that… · 氡是一种污染物,它……
Radon is a radioactive gas that rises from rock and soil and collects in basements. · 氡是一种放射性气体,从岩石和土壤升起,聚集在地下室里。
Good ____ (fresh air flow) is the simplest way to lower indoor pollution. · 良好的____(新鲜空气流动)是降低室内污染最简单的方法。
Good ventilation flushes pollutants out and brings fresh air in. · 良好的通风把污染物排出并引入新鲜空气。
The simple fix: fresh air
- Good ventilation 通风 flushes pollutants out.
- Opening windows brings clean air in.
- A carbon-monoxide detector warns of the invisible gas.
- Sealed, airtight buildings trap pollution — fresh air is the cure.
简单的解决办法:新鲜空气
- 良好的通风(ventilation)把污染物排出。
- 打开窗户引入干净的空气。
- 一氧化碳探测器警告这种看不见的气体。
- 密封、不透气的建筑困住污染——新鲜空气是解药。
Tightly sealed, poorly ventilated buildings can trap indoor pollutants and make them worse. · 密封严实、通风差的建筑能困住室内污染物并使它们更糟。
Without fresh air, pollutants build up indoors — sometimes higher than outdoor levels. · 没有新鲜空气,污染物在室内积累——有时比室外水平还高。
Select all · 所有 common indoor air pollutants. · 选出所有常见的室内空气污染物。
Carbon monoxide, radon, and tobacco smoke are all indoor pollutants. Fresh air is the cure, not a pollutant. · 一氧化碳、氡和烟草烟雾都是室内污染物。新鲜空气是解药,不是污染物。
There's a modern twist: making buildings airtight to save energy can trap indoor pollutants and make the air worse. Insulation and sealed windows cut heating bills, but without deliberate ventilation the carbon monoxide, radon, and vapours have nowhere to go. Energy efficiency and clean indoor air have to be balanced.
有一个现代的转折:把建筑造得密不透气以节约能源能困住室内污染物,使空气更糟。隔热材料和密封的窗户削减供暖账单,但没有刻意的通风,一氧化碳、氡和蒸气无处可去。能源效率和干净的室内空气必须平衡。
A sealed winter home:
- To save heat, every window is shut tight and gaps are sealed.
- A slightly faulty gas heater releases a trickle of invisible carbon monoxide, while radon seeps up from the rock below.
- With no fresh air coming in, both build up — until a detector beeps, or someone opens a window and the danger clears.
一个密封的冬季住宅:
- 为了省热,每扇窗都关得严严实实,缝隙也封上。
- 一个略有故障的燃气加热器释放一缕看不见的一氧化碳,而氡从下面的岩石渗上来。
- 没有新鲜空气进来,两者都积累起来——直到探测器鸣叫,或有人打开窗户,危险才解除。
Indoor air can be more polluted than outdoor air. Sources include burning (carbon monoxide from heaters, tobacco smoke) and materials/ground (radon from rock, asbestos from old insulation, vapours from new products). The simple fix is ventilation — but airtight, energy-saving buildings can trap pollutants unless fresh air is let in.
室内空气可能比室外空气更污染。来源包括燃烧(来自加热器的一氧化碳、烟草烟雾)和材料/地面(来自岩石的氡、来自旧隔热材料的石棉、来自新产品的蒸气)。简单的解决办法是通风——但密不透气、节约能源的建筑能困住污染物,除非让新鲜空气进来。
