3.3. Other data sources

There are many studies which have investigated pesticide pollution. Other data of European or worldwide coverage focused on the collection and assessment of pesticide contaminations were considered for the literature analysis (Table 3.7). Furthermore, pesticides data sources of European countries on pesticides are available, which focus on the registration of plant production products (see Annex 4). Box 2 shows an example on specific monitoring program for pesticides in Germany.

Overall, data availability from scientific projects are diverse and their quality may vary. Furthermore, sampling sites or research activities were mainly focussed on specific areas or model regions, which make comparison with routinely monitored sites rather difficult. The findings of such research projects can help to fill knowledge gaps but are less useful to fulfil data gaps in studies of temporal and spatial pesticide contamination.
