   Plants help reduce indoor air pollution
 
 NASA research has consistently shown that living, green and flowering plants can remove several toxic chemicals from the air in building interiors. You can use plants in your home or office to improve the quality of the air to make it a more pleasant place to live and work –where people feel better, perform better, any enjoy life more.
  NASA and the Associated Landscape Contractors of America (ALCA) have announced the findings of a 2-year study that suggest a sophisticated pollution-absorbing device: the common indoor plant may provide a valuable weapon in the fight against rising levels of indoor air pollution.
  Research into the use of biological processes as a means of solving environmental problems, both on Earth and in space habitats, has been carried out for many years by Dr. Bill Wolverton, formerly a senior research scientist at NASA’s John C. Stennis Space Center, Bay St.Louis, Miss.  Based on preliminary evaluations of the use of common indoor plants for indoor air purification and revitalization, ALCA joined NASA to fund a study using about a dozen popular varieties of ornamental plants to determine their effectiveness in removing several key pollutants associated with indoor air pollution. NASA research on indoor plants has found that living plants are so efficient at absorbing contaminants in
the air that some will be launched into space as part of the biological life support system aboard future orbiting space stations. NASA, scientists have identified 50 houseplants that remove many of the indoor pollutants and gases.
  NASA research has shown that some plants most effective in removing: Formaldehyde, Benzene, and Carbon Monoxide from the air. The common plants such as : Peace Lily - Spathiphyllum, Bamboo Palm – Chamaedorea Seifritzii,  Chinese Evergreen - Aglaonema Modestum,   English Ivy Hedera Helix,  Gerbera Daisy ,  Janet Craig - Dracaena , Marginata - Dracaena Marginata,   Mass cane/Corn Plant - Dracaena Massangeana,  Mother-in-Law’s Tongue - Sansevieria Laurentii, Pot Mum  – Chrysantheium morifolium, Warneckii - Dracaena  and many more. 
  Peace Lily (Spathiphyllum “Mauna Loa”)

     Peace Lily (Spathiphyllum)
  The Peace Lily is a compact plant which grows to a height of 3’ with a 2’ spread. This hardy plant tolerates neglect. It prefers indirect sunlight and high humidity, but needs to be placed out of drafts and should be thoroughly watered. The leaves should be misted frequently with warm water.
   Bamboo palm (Chamaedorea seifrizii)
  
     Bamboo palm
  Bamboo palm also called the “reed palm”,  prefers bright indirect light. This plant likes to stay uniformly moist, but does not like to be over-watered or to sit in standing water. Indoor palms may attract spider mites which can be controlled by spraying with a soapy solution..
 

 

  Lady Palm (Rhapis excelsa)

="     Lady Palm (Rhapis  excelsa)
  Lady Palm is a durable palm species adapts well to most interiors. The Rhapis are some of the easiest palms to grow, but each species has its own particular environment and culture requirements. This plant grows slowly, but can grow to more than 14′ in height with broad clumps often having a diameter as wide as their height.
  Rubber Plant (Ficus robusta)
   
    Rubber Plant (Ficus robusta)
   Rubber Plant grows in  indoors, preferring semi-sun lighting. Avoid direct sunlight, especially in summer. Young plants may need to be supported by a stake. The plant grows to 8’ with a spread of 5’. Wear gloves when pruning, as the milky sap may irritate the skin. Water thoroughly when in active growth, then allow the soil to become fairly dry before watering again. In winter keep slightly moist.
   Areca Palm (Chrysalidocarpus lutescens)

   Areca Palm (Chrysalidocarpus lutescens)
  Areca Palm is also called the “Butterfly Palm”. Areca Palm is an upright houseplant a vase shaped. Specimen plants can reach 10 to 12 foot in height. Keep the Areca Palm in  a humid area to avoid tip damage. This plant requires  pruning. Select an Areca palm  plant with larger caliber trunks at the base  as they are easier to maintain.
   Philodendron (Philodendron sp.)

    Philodendron (Philodendron sp.
  Philodendrons plant is one of the most durable of all house plants. Philodendrons prefer medium intensity light but will tolerate low light. Direct sun will burn the leaves and stunt plant growth. This plant is available in climbing and non- climbing varieties. When grown indoors, they need to be misted regularly and the leaves kept free of dust. Soil should be evenly moist, but allowed to dry between watering.

 

   Aloe Vera Plants 

    Aloe Vera
  
Aloe Vera plants are effective at eliminating many toxins, which cause indoor air pollution. No home should be without an aloe plant as it takes the sting out of burns, which you get, from a stove and even sunburns; this is indeed a handy plant.
   Dracaena “Janet Craig” (Dracaena deremensis)

  The Dracaena plant easy to grows up to 10 feet with a spread of 3 feet..These plants do best in bright indirect sunlight coming from the east/west. They can adapt to lower light levels if the watering is reduced. Keep the soil evenly moist and mist frequently with warm water and remove any dead leaves.  
   Dwarf Date Palm (Phoenix roebelenii) 
   Dwarf Date Palm is a hardy, drought-tolerant and long-lived plant. The Dwarf Date Palm needs a bright spot which is free of drafts. It grows slowly, reaching heights of 8 feet to 10 feet. The Dwarf Date Palm has sharp needle-like spines arranged near the base of the leaf stem, so these can easily penetrate skin and even protective clothing.
   Boston Fern (Nephrolepis exaltata )
   Boston fern plant grows up to 4 feet in height with a spread up to 5feet. It has feathery ferns which are best displayed as a hanging plant. Boston Fern plant  prefers bright indirect sunlight. Keep the soil barely moist and mist frequently with warm water. This plant is prone to spider mites and whitefly which can be controlled using a soapy water spray. 
   Ficus Alii (Ficus macleilandii)
   The Ficus Alii plants grows easily indoors, and resists insects. It prefers a humid environment and low to medium light when grown indoors but it should not be placed near heating or air conditioning vents, or near drafts because this could cause leaf loss. Soil should be kept moist but allowed to dry between watering.
  English Ivy plants 
  English Ivy is  a beautiful climbing plant and also gets rid of formaldehyde and indoor air pollution problems. This is a vine like plant that can easily have climb across archways. These plants are perfect in the living room, den, or office where there are pieces of wooden furniture or carpeting.
  
Harmful indoor air pollutants
   Harmful indoor air pollutants can cause a host of serious llnesses, including asthma, cancer, reproductive and neurological disorders and more than 1.6 million deaths a year, according to a 2002 World Health Organization report. The VOCs emanate from furnishings, carpets, plastics, cleaning products, building materials like drywall, paint, solvents and adhesives. Even tap water can be a source of VOCs. The air inside homes and offices is often a concentrated source of these pollutants, in some cases up to 100 times more polluted than outdoor air, according to research.
  
Chemicals found in indoor polluents 
   Trichloroethylene (TCE)  a commercial product found in a wide variety of industrial uses. Over 90 percent of the TCE produced is used in the metal degreasing and dry cleaning industries. In addition, it is used in printing inks, paints, lacquers, varnishes, and adhesives.. In 1975 the National Cancer Institute reported that an unusually high incidence of hepatocellular carcinomas was observed in mice given TCE by gastric intubation and now considers this chemical a potent liver carcinogen.
   Benzene  a very commonly used solvent and is also present in many common items including gasoline, inks, oils, paints, plastics, and rubber. It is used in the manufacture of detergents, explosives, pharmaceuticals, and dyes. Benzene has long been known to irritate the skin and eyes. Repeated skin contact with benzene will cause drying, inflammation, blistering and dermatitis. Acute inhalation of high levels of benzene has been reported to cause dizziness, weakness, euphoria, headache, nausea, blurred vision, respiratory diseases, tremors, irregular heartbeat, liver and kidney damage, paralysis and unconsciousness. Chronic exposure to even relatively low levels causes headaches, loss of appetite, drowsiness, nervousness, psychological disturbances and diseases of the blood system, including anemia and bone marrow diseases.
   Formaldehyde  a ubiquitous chemical found in virtually all indoor environments. The major sources which have been reported and publicized include urea-formaldehyde foam insulation (UFFI) and particle board or pressed wood products used in manufacturing of the office furniture bought today. It is used in consumer paper products which have been treated with UF resins, including grocery bags, waxed papers, facial tissues and paper towels. Many common household cleaning agents contain formaldehyde. UF resins are used as stiffeners, wrinkle resisters, water repellents, fire retardants and adhesive binders in floor coverings, carpet backings and permanent-press clothes. Other sources of
formaldehyde include heating and cooking fuels like natural gas, kerosene, and cigarette smoke. Formaldehyde irritates the mucous membranes of the eyes, nose and throat. It is also a highly reactive chemical which combines with
protein and can cause allergic contact dermatitis. The most widely reported symptoms from exposure to high levels of this chemical include irritation of the eyes and headaches. Until recently, the most serious of the diseases attributed to formaldehyde exposure was asthma. The Environmental Protection Agency (EPA) has recently conducted research which has caused formaldehyde to be strongly suspected of causing a rare type of throat cancer in long-term occupants of mobile homes.
