Using scented products indoors changes the chemistry of the air, producing as much air pollution as car exhaust does outside.

Researchers say that breathing in these nanosized particles could have serious health implications.

Scented wax melts are marketed as a flameless, smoke-free, non-toxic alternative to traditional candles.

The study was published in the journal Environmental Science & Technology Letters . Source: Purdue University .
