Scientists find scores of harmful chemicals in indoor dust including phthalates linked to developmental problems in babies
Household dust harbours a cocktail of toxic chemicals that have been linked to an increased risk of a range of health hazards, from cancer to problems with fertility, researchers in the US have found.
The chemicals are shed from a host of common products, from flooring to electrical goods as well as beauty and cleaning products.
“We think our homes are a safe haven but unfortunately they are being polluted by toxic chemicals from all our products,” said Veena Singla, co-author of the study from the Natural Resources Defense Council in California.
The scientists cautioned that children were particularly vulnerable to the health effects of contaminated dust as they often play or crawl on the floor and frequently touch their mouths. “They end up having a lot more exposure to chemicals in dust and they are more vulnerable to toxic effects because their brains and bodies are still developing,” said Singla.
Writing in the Environmental Science and Technology journal, Singla and colleagues described how they analysed 26 peer-reviewed papers, as well as one unpublished dataset, from 1999 onwards to examine the chemical make-up of indoor dust. The studies covered a wide range of indoor environments, from homes to schools and gymnasiums across 14 states.
“What emerged was a rather disturbing picture of many different toxic chemicals from our products that are present in dust in the home and [are] contaminating the home,” said Singla.
