A new study reveals the widespread presence of neonicotinoid pesticides, including acetamipride, in rainwater samples collected in Japan.
A study published in Environmental Monitoring and Contaminants Research has revealed the presence of neonicotinoid pesticides in rainwater samples collected in Japan. The research highlights the potential for widespread environmental contamination,with acetamipride being the most frequently detected substance. Acetamipride is a pesticide that some political factions in France are attempting to reintroduce.
The research team, led by Masumi Yamamuro of the University of Tokyo, collected rainwater samples from April 2023 to September 2024 in Tsukuba and Kashiwa, two Japanese cities situated in agricultural regions. The analysis revealed that 91% of the samples contained neonicotinoids,with acetamipride present in 82% of the samples. These pesticides are currently authorized for use in Japan, particularly for treating rice and pine monocultures.
Environmental Impact
The findings raise concerns about the potential environmental impact of neonicotinoid pesticides. According to chemist and toxicologist Jean-Marc Bonmatin of the National Center for Scientific Research, “The clouds have become a vector of contamination of the global environment.”
“The clouds have become a vector of contamination of the global environment.”
Study Details
The study focused on two cities: Tsukuba, with a population of 260,000, and Kashiwa, with 430,000 residents. Both are located in areas with significant agricultural activity, which may contribute to the presence of pesticides in the environment.
