Insecticides deadly to bees and fish found in Flemish waterways

Summary

Insecticides that destroy bee populations and also pose a danger to fish and birds have been found in Flanders waterways

 

Zouw stream most at risk

Neonicotinoids, the collective term for insecticides utilising nicotine substances and known to destroy bee populations, has been found in 90% of waterways recently tested in Flanders, according to recent measurements taken by the Flemish Environment Agency (VMM).

Neonicotinoids are controversial because they cause mass bee deaths and also threaten birds, fish and mammals. Several scientists and nature associations are demanding a total ban on the substances in Europe.

It was up to now unclear to what degree the substances were used in Flanders, but VMM’s results leave no room for doubt. Three insecticides were found in, respectively, 90%, 44% and 26% of the waters measured. Even early in the year, when the use of the products is prohibited, there was an excessive concentration of two of the three insecticides. One of the most polluted is the Zouw stream near Riemst in Limburg province.

“Neonicotinoids are used in substances to protect crops,” explained Katrien Smet of VMM. “Although only the agricultural sector can use these products, during specific periods, we still find excessive concentrations of the substances in our water streams.” According to VMM, the measuring data indicate there is a significant effect on the ecosystem.
