During the meeting, held in the US city, New Orleans, experts stressed that these substances promote the development of fat cells in a cellular model.
According to study leader Christopher Kassotis, "this is one of the first studies assessing the links between exposure to chemical mixtures present in the indoor environment and health t metabolic children living in those homes. "
The experts collected 194 samples of household dust from different homes in the center of North Carolina, the United States, removing the chemicals from the laboratory dust and analyzing their ability to promote the development of fat cells in a cellular model.
We found that two thirds of the dust pieces were able to promote the development of fat cells and half of them increased abundance of precursor fat cells at 100 micrograms, or about a thousand times lower than this. children eat it every day 'said Kassotis.
And that data from the Environment Protection Agency calculates that children eat between 60 and 100 milligrams of dust every day.
By measuring more than 100 different chemicals, the research team found that around 70 of the chemicals had a significant positive relationship with the powder-induced fat cell development, and around 40 were involved in the development of precursor fat cells. .
These results suggest that mixtures of chemicals that are produced in the indoor environment can cause excess weight or obesity in children, "Kassotis said.
Some of these chemicals are present in common household products, such as laundry detergents, household cleaners, paints and make-up; Scientists continue to study in order to decide which ones might be associated with obesity.
