Study on insecticide contamination in surface waters

Many thanks to a WTT contact in Ireland, Wolfgang Koepke of Graiguenamangh AC, for highlighting a study from a German university that points to some really worrying figures on insecticide contamination in surface waters, concluding that ​“the biological integrity of global water resources is at substantial risk”.

The paper is summarised in Science Daily — click here. 

Wolfgang has concerns (shared by many working in the river conservation world) that pesticides might be playing a significant role in what he perceives as reduced fly life in his rivers in Ireland. This paper gives plenty of food for thought.
