Assuming that your house is still standing after a disaster and the authorities haven't attempted to evacuate you, the best thing for you to do is to stay indoors with your air vents sealed.
For instance, in the event of an earthquake, a good amount of dust is stirred up into the air, bringing with it a number of soil fungi that have been shown to cause lung infections in earthquake survivors, such as coccidioidomycosis immitis which is the cause of San Joaquin Valley Fever. (
Refer to Jacobs, A.V. and Leaf, H. (2007). Fungal infections of the lung. Current Infectious Disease Reports, vol. 1, pp. 89-98 and Torre, J. and Richard, A.J. (2008). Coccidioidomycosis, emedicine, http://emedicine.medscape.com/article/781632-overview).
In the event of a nuclear fallout, there is the radiation factor. No biggy, right? Well, that's because you already know that it is best to go into your basement and seal off any openings to the outside in your home and stay down there for at least 3 weeks. (Note: Earthquake and Nuclear preparedness and disaster response will be discussed in more detail in a later post.)
So how do you survive in an air tight environment for a few weeks? Yep, you guessed it:
Plants!
Not only do plants convert carbon dioxide to oxygen, they also filter harmful substances from the air such as formaldehyde (
man, plants would've been great to have around when I was in Cadaver class), benzene, and trichloroethylene. So in a nutshell, plants function as amazing air pumps and humidifiers. (

In 1989, NASA scientists Dr. B.C. Wolverton, Anne Johnson, and Keith Bounds conducted a study to find an economical way to purify air for the extended stays that astronauts made in space stations. (

This study found that a particular fifteen houseplants performed better at air filtration than was ever expected.
Wolverton stated that, "
Plants take substances out of the air through the tiny openings in their leaves (stoma). But research in our laboratories has determined that plant leaves, roots and soil bacteria are all important in removing trace levels of toxic vapors. Combining nature with technology can increase the effectiveness of plants in removing air pollutants. A living air cleaner is created by combining activated carbon and a fan with a potted plant. The roots of the plant grow right in the carbon and slowly degrade the chemicals absorbed there."The plants were also found to be helpful to air-tight office buildings. For instance, in most office buildings, trapped pollutants produce what is often referred to as Sick Building Syndrome. (
http://en.wikipedia.org/wiki/Sick_building_syndrome)
The signs and symptoms of this syndrome include: fatigue, nausea, confusion, flu-like symptoms, sinusitis, anxiety, pneumonia, headache, lack of concentration, edema, allergies, and insomnia, irritation of the eyes, nose and mouth.
Now if you're wondering how formaldehyde, benzene, and trichloroethylene get into
your house, they do it like every other criminal, they pick the locks. No really, they are more like vampires, you invite them in... by bringing paper, cardboard, particle board, insulation, paints, oil solvents, adhesives, inks, varnishes, perfumes, deodorants, body lotions, cleaning products, smoke, pesticides, synthetic fabrics, carpets, detergents, etc. into your home. Darn, there goes the good things in life.
So here you are stuck in your house, trying to avoid the nuclear fallout like every other normal, non-mutant person, and all you have is books to read and walls to paint. Then you get that cleaning urge because you've got nothing to do except stare at the dust collecting on all the DVDs you can't use because the power is out. So, you clean and of course you have to varnish what remains of your furniture... and now you need to apply three layers of deodorant because you stink from all that work.
But then, suddenly, one of the radiation mutated cockroaches from the underworld just ate your dog and you have to whip out two cans of industrial strength bug spray because there is no way in Tartarus that your shoe is big enough to kill that thing. What do you do?
You get out your Mother-in-law's tongue. No, you don't have your mother-in-law to lick the roach to death; Mother-in-law's tongue is actually a plant called Snake Plant or Sansevieria trifasciata that filters all the chemicals from the above scenario. Please see the adjoining picture. (

In other words, you prepare with plants. The following is a list of the top 15 plants that NASA found were helpful in filtering indoor air:
1.
Philodendron scandens 'oxycardium,' or heartleaf philodendron (This is that plant that never seems to die, no matter how much you lack a green thumb. Picture is to the left.
plantoftheweek.org)
2.
Phildendron domesticum, elephant ear philodendron
3.
Dracaena fragrans, 'Massangeana', cornstalk dracaena
4.
Hedera helix, English Ivy
5.
Chlorophytum comosum, Spider plant. (I love this plant; you only have to water it once every two weeks! Perfect for times of disaster.
www.webmaster-forums.net)
6.
Dracaena deremenesis 'Janet Craig', Janet Craig dracaena (medium light)
7.
Dracaena deremenesis 'Warneckii', Warneckii dracaena (medium light)
8.
Ficus benjamina, weeping fig (intense light)
9.
Epipiremnum aureum, golden pathos
10.
Spathiphyllum 'Mauna Loa,' peace lily (in low light, this plant works the best)
11.
Philodendron selloum, selloum philodendron
12.
Aglaonema modestum, Chinese evergreen
13.
Chamaedorea sefritzii, bamboo or reed palm
14.
Sansevieria trifasciata, snake plant, mother-in-law's tongue
15.
Dracaena marginata, red-edged dracaena
NASA suggested that there should be at least two plants per 100 square feet, or two plants per a small room/office. The results recommended 15 to 18 houseplants, grown in 15cm containers or larger, to filter an average home of less than 2,000 square feet. My grandma seems to apply the more is better rule: her kitchen looks like the rain forest.
For those of you whom are interested in which plants filter what chemicals....
Filters of Formaldehyde:Green Spider plant, Peace lily, Bamboo palm, Mother-in-law's tongue, draecena marginate, golden paths, and dracaena warneckei.
Beaters of Benzene:Peace lily, Bamboo palm, Gerbera daisies, Mother-in-law's tongue, English Ivy, and Pot mums (my grandma loves these).
Tricklers of Trichloroethylene:Peace lily, Bamboo palm, and Gerbera daisy.
Well, again, I better sign off for today. Again, i must hit the books.
May you enjoy your time with your Mother-in-law's tongue.
