But very little monitoring of their concentration in soils or water is done, a failing recently condemned by a UK government chief scientific adviser.

The first systematic testing of neonicotinoids in rivers in Britain was mandated by EU water regulations and conducted in 2016. The results, obtained by the conservation charity Buglife, show that half of the 16 rivers tested in England had either chronic or acute levels of contamination. Of the 23 rivers tested across Britain, neonicotinoids were not detected in six.
