Persistently high pesticide levels found in small streams

Persistently high pesticide levels found in small streams

Small watercourses are contaminated with large numbers of herbicides, fungicides and insecticides. A new study shows that the legal requirements specified for water quality are not met in any of the five Swiss streams investigated. Indeed, thresholds for acute toxicity to aquatic organisms were also exceeded.

Neonicotinoids - harmful to soil organisms?

Neonicotinoids - harmful to soil organisms?

The neonicotinoids imidacloprid and clothianidin were detected in soil of sugar beet, wheat and corn fields as well as in soil of ecological compensation areas. The toxicity of the substances to the beneficial springtail was determined. It was shown that the measured concentrations represent a potential risk for springtail health.
