Re: [Aroid-l] depolluting plants

From: "Marek Argent" <abri1973 at wp.pl> on 2011.12.13 at 00:04:42(22471) Hello, They tested only the most popular houseplants, so it makes me suppose that there are a lot of depolluting plants among aroids, especially these with broad leaves, living in humid, shady places. I read somewhere that plants such ecosystems emit beneficial negative ionisation what reduces stress and relaxes, oppositely to thorned xerophytes from dry biomes which ionisate positively. We often feel much better in forests, especially after rains, and we get stressed in deserts.

I apologize. But I think everyone has understood what I wanted to say. Some of my friends say that is only to trade and sell plants, other friends think that plants act against the pollution. It is a long debate which is very interesting because the family Araceae is well represented.

It seems from your message that people are advertising plants as being "de-polluted". Is that correct? If that is so, my initial reaction is that it is a false claim. The amount of pollution is going to be almost unimaginably low in a cultivated plant that looks healthy. Even if a plant did have some low level of pollution (and one wonders what that term might mean; it could mean heavy metals, plutonium, organic toxins, or any number of substances) in its tissues, unless you ate a very large quantity, the transfer to you or your environment will be essentially nil. Maybe someone else has better information here. But you raise my natural scientific skepticism.
