中文导读

很多办公室会在桌上、架子上放几盆绿植，主要是因为好看。可是它们能不能让室内空气更干净、温度更低？文章介绍英国萨里大学牵头的一项国际综述：先交代综述的作者、期刊和研究范围，并区分“被动”和“主动”两类室内绿化；再说明主要数字——某些有害气体减少约 10%–30%，部分办公区域制冷所需能量降低 22%–27%；接着用 however 引出证据上的问题：多数研究在实验室小箱子里、只测几个小时到两天；随后说明效果取决于通风、光照、植物种类和数量，以及湿热天气下可能出现的潮湿和霉菌；最后落到研究者的下一步计划和“几盆植物不能代替良好通风”的结论。阅读时可留意 may、could、often、at least 等词如何限定结论的范围。

正文

Many offices keep a few plants on desks or shelves because they look nice. But can they also make a building cleaner and cooler? A new international review led by the University of Surrey in the UK suggests that the answer may be yes, with some important limits.

很多办公室会在桌上或架子上放几盆植物，因为它们看起来很舒服。但它们能不能让建筑更干净、更凉快？英国萨里大学牵头的一项新的国际综述表明，答案可能是肯定的，但也有一些重要的限制。

The review was published in the journal Eco-Environment and Health. A team of 35 experts, led by Surrey’s Global Centre for Clean Air Research, looked at 60 earlier studies from around the world. These studies tested two main kinds of indoor greening. Passive systems include potted plants, green walls and indoor trees. Active systems use fans or pumps to push air through plants and the material they grow in.

这项综述发表在《生态环境与健康》（Eco-Environment and Health）期刊上。由萨里大学全球清洁空气研究中心牵头的 35 位专家回顾了世界各地此前的 60 项研究。这些研究测试了两大类室内绿化。被动系统包括盆栽植物、绿墙和室内树木。主动系统则用风扇或泵推动空气流过植物及其生长介质。

The results were encouraging. Passive greening usually reduced certain harmful gases by about 10 to 30 per cent. These gases come from everyday products such as paint, furniture and cleaning products. In some office areas, plants and green walls also reduced the energy needed for cooling by 22 to 27 per cent. The air around the plants was often 0.5 to 4.5 degrees Celsius cooler, which could mean less use of air conditioning. Active systems were often even better at removing pollution, at least under controlled conditions.

结果令人鼓舞。被动绿化通常能让某些有害气体减少约 10% 到 30%。这些气体来自油漆、家具和清洁用品等日常产品。在一些办公区域，植物和绿墙还让制冷所需的能量降低了 22% 到 27%。植物周围的空气往往凉快 0.5 到 4.5 摄氏度，这可能意味着更少使用空调。主动系统在去除污染方面往往效果更好，至少在受控条件下是这样。

However, the review also found a problem with the evidence. About 59 per cent of the studies took place in laboratories, and only about a third measured plants in real buildings. Many tests used very small boxes and lasted only six to 48 hours. Plants in these tests often removed more pollution than plants in real rooms, where air moves in and out all the time. Most studies also looked at only a few common plant types.

不过，这项综述也发现了证据方面的问题。约 59% 的研究在实验室里进行，只有大约三分之一在真实建筑中测量植物。许多测试使用很小的箱子，只持续 6 到 48 小时。这些测试中的植物去除的污染，往往比真实房间里的植物更多，因为真实房间里的空气一直在进进出出。大多数研究也只关注了少数几种常见植物。

The effect of indoor plants depends on many conditions, such as fresh air, light, the type of plant and the number of plants. In low light, for example, plants take in less carbon dioxide. The team also warned that very hot and wet weather could cause another problem. If water is not managed well, greener rooms may become too damp, and mould could grow.

室内植物的效果取决于许多条件，比如新鲜空气、光照、植物种类和植物数量。例如，在光线较暗时，植物吸收的二氧化碳会减少。研究团队还提醒，非常炎热潮湿的天气可能带来另一个问题。如果水分管理不好，绿植更多的房间可能会变得过于潮湿，并可能长出霉菌。

Professor Prashant Kumar, who led the work, said the review gives a first benchmark for deciding where and how indoor plants can work best. The researchers now want longer studies in real buildings and clearer ways to report results. For now, a green office may help, but a few plants cannot replace good ventilation.

主持这项工作的普拉尚特·库马尔（Prashant Kumar）教授说，这项综述为判断室内植物在哪里、以何种方式最能发挥作用提供了一个初步基准。研究者们现在希望在真实建筑中开展更长期的研究，并用更清晰的方式报告结果。就目前而言，绿色办公室也许有帮助，但几盆植物无法代替良好的通风。
