Typology: Descriptive indicator (Type A - What is happening to the environment and to humans?)

Unit of measure

The indicator is expressed as percentages of monitoring sites where one or more pesticides exceed the effect threshold for surface waters or the quality standard for groundwater. To reduce the impact of uneven spatial and temporal data reporting, we used a country area weighting factor:

∑ Share of monitoring sites with exceedances per country (%) × country area (km²) /

∑ Area of countries with reported monitoring sites per year (km²)

The country weighting factor was not used for Figure 2 in the indicator.

Frequency of dissemination: Once a year
