This includes air fresheners, shampoos, soaps, scented candles, laundry detergents and cleaning products. There is no legal requirement for these products to list all their ingredients, and while the compounds they contain may each have individually been tested for toxicity, we don’t know how dangerous they become when mixed. Ironically, many of the pollutants seem to come from ingredients to make the products smell clean and fresh. When fragrance compounds like limonene and other terpenes get into the air, says Steinemann, they can react with ozone to generate compounds such as formaldehyde, which is carcinogenic. How we build modern homes compounds the problem. “What we’ve done to our housing is to seal it to prevent energy loss,” says Stephen Holgate at the University of Southampton, UK. The problem is worst in the most efficient homes. “Ventilation is very low, and chemicals can accumulate in the air and dust.” Cleaning products aren’t the only source of pollutants – paint,
