 　　Indoor air pollution is a common threat to human health, the new study looked at five common house plants and found that when it comes to removing harmful chemicals from the air, those five plants are better than others.

　　室内空气污染对人类健康是一种常见的威胁，当我们谈到净化空气中的有害化学物质，这五种植物比其它植物更有效。

　　净化室内空气 选这些植物就对了！

　　Dracaena

　　香龙血树

　　All five plants did a good job removing acetone (you’ve probably noticed its smell in nail salons—the pungent¹ chemical is present in nail polish remover). But the popular Dracaena plant, with its trunk-like stems and shiny leaves, took in more of the gas than any other greenery tested (94% over the 12-hour study period).

　　五种植物都能起到去除甲醛的作用（你可能已经注意到在美甲店里的气味就是它——在卸甲水中刺鼻的化学物质）。但是这种受欢迎的龙血树植物，拥有像树干一样的茎和关泽的叶子，在环保测试中它比其它任何植物能去除更多的有害气体（在超过12个小时的观察时间中，龙血树吸收了多达94%的丙酮）。

　　Jade² plant

　　翡翠木

　　Out of the five plants tested, this easy-to-care-for succulent—also known as a friendship tree, lucky plant, or money tree—was the best at removing toluene (91%), a strong-smelling chemical often associated with paint thinners.

　　Spider plant

　　吊兰

　　Bromeliad

　　凤梨花

　　This spiky⁶, colorful house plant (it’s related to the pineapple!) was best at removing benzene (92%), a toxic⁷ gas present in motor vehicle exhaust and cigarette smoke. It was also the most effective, overall, at removing multiple VOCs—taking up more than 80% of six out of the eight chemicals studied. For this reason, it could be a good plant to have sitting around in the household or workplace.

　　这种镰刀状，彩色的室内植物（经常联想到菠萝！）是去除空气中苯最好的绿植（92%），苯这种有毒气体存在于机动车排放的尾气和香烟中。对于净化多种挥发性有机物它的效果也是最好，最全面的——它能有效祛除8种挥发性有机化合物中的6种，每种物质的净化率超过80％。因此，在你的家里或者办公地点摆上一盆凤梨花是最好的选择。

　　Caribbean Tree Cactus⁸

　　仙人掌

　　These hardy⁹ cacti¹⁰ produce tiny flowers and grow well with lots of sunlight. While it was not the best at removing any one chemical, it did still remove more than 80% of ethylbenzene, p-Xylenes, and acetone, and about 60% of benzene, toluene, and o-Xylene.

　　这些顽强的小仙人掌能长出小花，在充足的阳光下长势很好。虽然它对净化任何一种化学物质都不是最好的，但是他依旧能超过80%的乙苯，邻二甲苯和大约60%的苯，甲苯和二甲苯。
