自從Ally出身後,我們仨一直是”co-sleeping” 把她的BB床放在我跟烱太太的床旁邊一起睡。但Ally很快兩歲了(How time flies!),所以炯叔叔跟炯太太最近忙著裝修一下我家的另一間房間(其實我家只有兩間房),搭建Ally未來的睡眠和活動空間。

炯叔叔這裡想談的不是裝修,是那些油漆、木材、水泥、家具釋放的毒氣。

傳統智慧當然是裝修後打開窗把房間/房子吹2-3個月先好住人。但真的就是那麼簡單嗎?

當然不是!

其實我們每一天在家裡和在辦公室可能吸入很多不同毒氣。這些毒氣主要來自現在的家具的合成物料(synthetic furnishings)和我們現代密封式建築(hermetically sealed buildings)的有關。

根據the US Environment Protection Agency (EPA)對大廈和住屋室內空氣的研究,可以主要歸納三點:

1)每一個人平均每一天呼吸20,000次,帶動大約10,000 升(litres)空氣進肺內。在城市生活的人往往有90%的時間是在室內的。所以室內空氣對人的影響很大。

2)EPA 認為室內的空氣污染比室外的高3-7倍,為頭五項影響公眾健康之一。

3)EPA 更認為10個住屋和大廈中,6家有問題危害人體健康 。哮喘、過敏、頭痛、鼻敏感、疲勞、氣管不適等等的症狀, 病源有可能來自所謂的“Sick Building Syndrome”

氡氣(Radon)、三氯乙烯(trichloroethylene)、甲醛(formaldehyde)、苯(benzene)。。。等等統稱為Volatile Organic Compounds (VOCs),傷害你於無形。

其實在室內有害的物質包羅萬有,下面的Table 1 給你一個大概的總覽。

係唔係從來冇想過原來平時接觸嘅嘢都可以咁毒嘅呢?

依,聽落去咪死梗????巧驚驚喔!

咁又唔駛驚。

有趣的是,在70年代美國太空總署(NASA)為太空人研究長住大空淨化空氣時發現某一些植物除了可以供應大量氧氣外還可以清除空氣裏的污染物。NASA更做了一間密封的Biohome在來做實驗。

BioHome

這Biohome基本上用合成材料建造(即係話間屋毒到冇朋友),全屋密封(毒上加毒),為一個人生活而設計(邊個去住咁唔好彩呢?)。NASA發現在放植物之前,每一個入去Biohome的人,都會馬上有Sick Building Syndrome如眼痛或氣管不適。

NASA對那些植物的研究,後來由一位博士叫B.C. Wolverton在他的一本叫“How to Grow Fresh Air: 50 Houseplants that Purify Your Home or Office”的書公開。這書集合了NASA 25年來的研究成果,明確闡述不同植物對空氣淨化的不同好處。大概撮要如下:

Plant name

Description Chemical vapor removal1 Light require­ment Remarks
Areca palm (butterfly palm), Dypsis lutescens Clusters of erect, slender, cane-like stalks with feathery yellow-green fronds.

8

Sun to semi-sun Releases an abundant amount of moisture into the air. Fast growing.
Bamboo palm, Chamadorea elegans or C. erumpens Clusters of small slender canes. Graceful fans with rich green color.

9

Semi-sun Releases an abundant amount of moisture into the air. Easy to care for.
Boston fern, Nephrolepis exaltata Stiff fronds arch outwards, drooping downward as they age.

9

Semi-sun Releases an abundant amount of moisture into the air. Ideal for hanging baskets. Mist and water frequently to reduce leaf drop.
Corn plant, Dracaena fragrans ‘Massangeana’ Shiny medium green leaves with a bold yellow-white stripe down the center. Develops a solid woody stem. Leaves concentrate at the top of each stem.

8

Semi-shade Survives in dimly lit areas. Occasionally will send up a small spray of fragrant white flowers.
Dendrobium orchid Has beautiful exotic blooms, usually in clusters or in a row along canes.

7

Semi-sun Flowers are long lasting.
Dracaena deremensis ‘Janet Craig’ Erect stems with a rosette of broad, smooth, glossy, darkgreen leaves 12 inches long and 2 inches wide.

8

Semi-shade Grows quickly. Tolerates dimly lit areas, but growth will be slow.
Dracaena deremensis ‘Warneckei’ Leaves, 2 feet long and 2 inches wide, are green with white and gray-green stripes.

6

Semi-shade Grows slowly. Tolerates low light and dry air. Retains its variegation in low light.
Dragon tree, Dracaena marginata Smooth, gray, erect canes. Leaves, 2 feet long and 1/2 inch wide, are deep, glossy green with red edges along the margins. Leaves cluster at the end of each cane.

6

Semi-sun to semi-shade Tolerates relatively low light and dry air.
Dumbcane, Dieffenbachia varieties* Wide, blotched green and white (cream) leaves. Unbranched stems arch downward.

7

Semi-sun to semi-shade Fast growth.
Dwarf date palm, Phoenix roebelini Stately main trunk with graceful, green fans that droop elegantly. Fronds reach 3 feet and grow horizontally.

9

Semi-sun Very slow grower. Adapts well to low light levels.
English ivy, Hedera helix* Vigorous climber which sends out aerial roots that attach to any surface. Dark green leaves have 3 to 5 lobes.

9

Semi-sun to semi-shade Easy to grow. Ideal for hanging baskets. Generally does not do well in high temperatures.
Ficus bennendijkii ‘Alii’ Slender dark green leaves. 7 Full sun and semi-sun

Easy to grow. May have some leaf drop until it adjusts to its new location.

1Rating 1 to 10, with 10 being excellent. *May be hazardous or toxic if eaten or comes in contact with eyes or skin; keep plants away from children.

之前有一位印度朋友叫Kamal Meattle在TED Talk裡也分享過用植物淨化空氣經驗。你們看看那個video.

所以,你們可以想像到Ally的房間裝修好之後,將會有好多好多植物放在她的房間,吸呀吸呀吸呀吸呀吸呀吸呀。。。

其實NASA那個研究不單單適用於新裝修的房屋,對於現時你們正在住的房屋或者是辦公室也適用。

記住,除了小心飲用的含鉛外, 室內空氣也要小心!
