The vertical bars represent the time-weighted mean concentration of active substances as measured during the period May to September of each year between 1992 and 2018 (except only May to June in 1993). The dots represents the total amount of active substances (of those analysed) that were applied on field in the Vemmenhög area during the same period (1992-2018). The two vertical lines show that the first significant reduction in the concentration of active substances occurred in 1995, following the onset of the provision of site-specific guidance to farmers on how to prevent the release of pesticides to local surface waters. The second fall in pesticide levels was seen in 1998, after the implementation of economic incentives by the government and industry.
