A large-scale European study shows that pesticides are widespread in our environment and in humans. The SPRINT project, coordinated by Wageningen University (NL), makes it clear that a fundamental change in agriculture is inevitable.
A large-scale European study shows that pesticides are widespread in our environment and in humans. The SPRINT project, coordinated by Wageningen University (NL), makes it clear that a fundamental change in agriculture is inevitable.
The five-year SPRINT project (2020–2025) investigated agricultural regions in ten European countries and Argentina. The results are nothing short of alarming. Up to 40 different pesticides per sample were found in soil, water and air. Researchers found an average of 65 to 80 pesticides in house dust, a quarter of which are now banned. Some substances disrupt the intestinal flora and can even influence behaviour via the brain-gut axis.
"People and ecosystems are exposed to complex mixtures of pesticides – often including substances that have been banned for years," says project leader Prof. Violette Geissen of Wageningen University.
Current legislation does not take this chemical cocktail into account. Risk assessments usually test one substance at a time, while in reality there are hundreds of combinations. Children and pregnant women appear to be particularly vulnerable.
The research team is calling on policymakers to implement stricter supervision and a rapid transition to agroecological alternatives. These include crop rotation, mechanical weed control, greater biodiversity and financial incentives for farmers who take steps towards pesticide-free agriculture.
Nevertheless, the report also offers some rays of hope. In countries such as Portugal, Spain and Slovenia, farmers are demonstrating that there is another way. Through organic viticulture, natural pest control and short supply chains, they are successfully producing without synthetic agents – and with healthy margins.
The researchers conclude that the agricultural transition is not only about technology, but also about behaviour, cooperation and fair support for farmers.
"We cannot expect farmers to change without the right resources and incentives," says Geissen.

The overseas grape season starts in mid-December, but planning begins now. Demand for organic grapes remains strong and our growers need early visibility on the volumes they can reserve for fixed programmes. By aligning programmes in advance, we can secure organic volumes more effectively and are also in a stronger position to offer competitive pricing.
Along the Orange River in South Africa’s Northern Cape lies Carpe Diem, a long-standing and trusted partner for our organic grapes. Owner Gog van der Colff took over the family business in 2000 and made the deliberate decision to switch to organic farming in 2006. What began as a step that not everyone was initially convinced by has developed into a progressive organic farm producing grapes, pecans and raisins.
El Niño is clearly affecting the South American mango season this year. Higher temperatures and unusual rainfall patterns are disrupting flowering, making availability and harvest timing less predictable.
