| 0:00.0 | This is scientific American 60 second science. I'm Christopher Intagiyata. |
| 0:07.0 | Air pollution outside is easy to spot, hanging over the city or sputtering from a tailpipe. |
| 0:13.0 | But there's a lot of indoor air pollution too, |
| 0:15.0 | even if it's not as obvious. |
| 0:17.0 | It's caused by volatile organic compounds, or VOCs. |
| 0:21.0 | They can come from building materials like paint, carpets and adhesives, vinyl floors, varnishes, solvents, etc. Vadud Niri, an analytical chemist at the State University of New York Oswego. |
| 0:37.0 | And also they can come from home and personal care products like cleaning chemicals, air fresheners, cosmetics. |
| 0:46.0 | And that cosmetics part is what caught Nere's attention. |
| 0:49.0 | One day when I went to a nail salon with my wife, I noticed the smell of specifically acetone in there, and since I was doing it analysis in that time, I thought maybe we can do something about this. |
| 1:05.2 | Acetone can irritate your eyes, skin, nose and throat and at high concentrations |
| 1:10.4 | can cause nausea, headaches or other nervous system problems. |
| 1:14.0 | Nerei figured that one way to get rid of acetone might be with house plants. |
| 1:19.0 | So we reviewed decades of literature in the field of plants as environmental cleanup agents, which is called |
| 1:24.5 | biofiltration or phytoremediation. |
| 1:27.4 | He then ran his own experiment using an airtight chamber, 8 VOCs in concentrations similar to those found in nail salons and five common house |
| 1:36.4 | plants. A jade plant, a spider plant, a bromeliad, a Caribbean tree cactus, and what's known as a Dracina plant. |
| 1:45.0 | Turns out after a 12-hour test, it was the bromeliad that scrubbed the most chemicals from the air. |
| 1:51.0 | But as for his original quest, removing acetone from nail salons, the Drosina beat all the others, sucking |
| 1:58.0 | up 94% of the offensive compound. |
| 2:01.2 | He presented the results at a meeting of the American Chemical Society in Philadelphia. |
| 2:05.0 | Niri hasn't worked out all the details on the nail salon solution yet. |
| 2:10.0 | That's next. But for a house or apartment, he says. |
