Researchers found traces of 170 pesticides on several dozen farms in Groningen and Friesland. Traces of 144 different pesticides were also detected in urban areas.
European regulations set limits only on individual pesticides, per type, but there are currently no rules for exposure to combinations of pesticides. This is currently being worked on by the European food authorities at EFSA.
Dust from rural homes was tested for 207 pesticides. The most common pesticide was the herbicide glyphosate, followed by two pesticides that are no longer approved on the European market but degrade very slowly. 'Compared to other EU countries, the Netherlands has high levels of pesticides in farms,' said soil physics professor Violette Geissen recently to Nu.nl.
According to EFSA, about 40% of the pesticides detected in farm dust are 'possibly or very likely' carcinogenic. Results are expected this year from a study on Parkinson's disease in the Bollenstreek region, where many pesticides are used.
In response, the LTO said it welcomed the research. It is important that farmers and their families can work in a safe environment, a spokesperson said. Most pesticides are considered safe, but if research shows otherwise, action must be taken.
