Study Finds Almost 200 Pesticides in European Homes

Almost 200 pesticides have been found by a study examining dust in homes around Europe, as scientists say regulators need to take 'toxic cocktails' of chemicals into account when banning or restricting the use of pesticides. From a report: Scientists say their research supports the idea that regulators should assess the risks posed by pesticides when they react with other chemicals, as well as individually. They say this should apply to substances already in use, as well as those yet to be approved.

In preliminary findings from the largest study of its kind, scientists examining household dust from homes in 10 European countries in 2021 detected 197 pesticides in total. More than 40% of the pesticides found in the dust have been linked to highly toxic effects, including cancer and disruption of the hormonal system in humans.

The number of pesticides in each home ranged between 25 and 121, and levels of pesticides tended to be higher in the homes of farmers. Prof Paul Scheepers, of the Radboud Institute for Biological and Environmental Sciences, said: 'We have many epidemiological studies showing that diseases are associated with mixtures of pesticides.'
