On Wednesday we finished off with a piece of advice about clean air and indoor plants. Tonight we wanted to follow up on that comment.
What's the problem with indoor air?
"The indoor environment is five to ten times more polluted than the exterior"
(1994 CSIRO review)
"In recent years, comparative risk studies performed by the US EPA and its Science Advisory Board have consistently ranked indoor air pollution among the top five environmental risks to public health" (US EPA, 1993)
The average Australian spends 90 percent or more of their time indoors. Despite this, relatively little research has been done on the quality of air in our homes, schools, recreational buildings, restaurants, public buildings, offices and cars. According to the Commonwealth Government many chemicals present in indoor air environments have not been thoroughly tested and little is known about their long-term health effects. Even less is understood about the health effects from constant exposure to mixtures of these chemicals.
What are some of the other benefits of indoor plants?

- Consider the amount of sun your indoor plants are likely to receive (some can survive on less light than others).
- Keep watering schedules regular (use a calendar).
- Periodically clean each plant with a damp cloth to ensure proper absorption of air particles and toxins.
- Keep their soil replenished with organic compost.
- If possible use rainwater for your plants.
