Study: Home cleaning and cooking contaminate more than the use of a combustion car

Activities such as cleaning the house or cooking produce chemical components that pollute the air more than a car, said a study published this Sunday by the University of Colorado in the United States. United.

The report, presented at the annual meeting of the American Association for the Progress of Science (AAAS), "was based on the badysis of the air impact of" chemical compounds volatile "present in articles such as shampoo, perfumes and detergents."

According to experts, chemical compounds that escape homes due to daily activities globally contribute to polluting the atmosphere "more than cars and trucks".

"Housing has never been considered a major source of air pollution," said Marina Vance, a specialist in university centers, who initiated a field study in 2018.

Vance said the preliminary results confirm that even boiling water can contaminate the air, because the flame of some kitchens contains "high levels of gaseous pollutants" or that the preparation of a toast alters the quality of the air more than we thought.

Another researcher, Joost de Gouw, pointed out that "it is too early to recommend changes in public policy or human behavior", as additional research is needed to badyze the amount of toxins present in the world. air inside the building. the houses.
