Landau, 21.01.2025 – In conventional agriculture, synthetic chemical pesticides are used in various crops such as arable farming, vegetable growing and viticulture. A study by the RPTU University Kaiserslautern-Landau, recently published in the journal “Scientific Reports”, is the first to examine pesticide contamination over the course of a year. It shows that substances can be detected not only during the spraying periods in the fields, but also throughout the year and in adjacent meadows. The impact of these chronically detected complex pesticide mixtures on the environment has not been sufficiently investigated and could be significant.
