A recent study by the RPTU University Kaiserslautern-Landau shows extensive pesticide contamination in the landscape of the Upper Rhine Region. The research team led by Carsten Brühl shows for the first time that synthetic chemical pesticides from conventional agriculture do not remain on the cultivated areas, but spread from the lowlands to the Black Forest and the Palatinate Forest. The results show that the entire landscape is contaminated with pesticide mixtures, shedding new light on the potential environmental impacts of conventional agriculture. According to the researchers, pesticide use must be reduced urgently in order to protect areas around fields, orchards and vineyards.
