研究发现：室内盆栽并不能真正改善空气质量
<p>在室内放上绿色盆栽让人感觉良好，似乎空气也变得清新起来，然而研究发现，室内盆栽并不能有效地净化空气，效果远不如开窗通风和空气净化器。</p><p><span word="In">In</span> 1989, <span word="NASA">NASA</span> <span word="conducted">conducted</span> <span word="its">its</span> <span word="famous">famous</span> <span word="Clean">Clean</span> <span word="Air">Air</span> <span word="study">study</span> <span word="to">to</span> <span word="see">see</span> <span word="whether">whether</span> <span word="common">common</span> <span word="houseplants">houseplants</span> <span word="might">might</span> <span word="purify">purify</span> <span word="indoor">indoor</span> <span word="air">air</span> <span word="by">by</span> <span word="removing">removing</span> <span word="toxins">toxins</span> <span word="in">in</span> <span word="addition">addition</span> <span word="to">to</span> <span word="absorbing">absorbing</span> <span word="carbon">carbon</span> <span word="dioxide">dioxide</span> <span word="and">and</span> <span word="releasing">releasing</span> <span word="oxygen">oxygen</span>. <span word="It">It</span> <span word="worked">worked</span>, <span word="and">and</span> <span word="while">while</span> <span word="plants">plants</span> <span word="are">are</span> <span word="still">still</span> <span word="capable">capable</span> <span word="of">of</span> <span word="absorbing">absorbing</span> <span word="harmful">harmful</span> <span word="toxins">toxins</span> <span word="in">in</span> <span word="the">the</span> <span word="air">air</span>, <span word="new">new</span> <span word="research">research</span> <span word="suggests">suggests</span> <span word="that">that</span> <span word="potted">potted</span> <span word="plants">plants</span>’ <span word="ability">ability</span> <span word="to">to</span> <span word="improve">improve</span> <span word="air">air</span> <span word="quality">quality</span> <span word="in">in</span> <span word="the">the</span> <span word="home">home</span> <span word="or">or</span> <span word="office">office</span> <span word="is">is</span> <span word="largely">largely</span> <span word="overstated">overstated</span> <span word="and">and</span> <span word="buries">buries</span> <span word="a">a</span> <span word="more">more</span> <span word="effective">effective</span> <span word="solution">solution</span> <span word="to">to</span> <span word="keeping">keeping</span> <span word="the">the</span> <span word="air">air</span> <span word="clean">clean</span>.</p><p>1989年，美国国家航空航天局进行了著名的清洁空气研究，以观察普通室内植物除了吸收二氧化碳和释放氧气之外，是否还能通过排除毒素来净化室内空气。当时的研究证明这种方法起到了作用。但尽管植物能够吸收空气中的有害物质，新研究却表明，盆栽植物改善家庭或办公室空气质量的能力在很大程度上被夸大了，使我们忽视了一个保持空气清洁的更有效的办法。</p>
