Research objectives: The Ministry of LNV has indicated that risk assessment methodologies have to be developed, validated, reviewed or improved for the protection goal; risk to aquatic organisms. A major input route for the risk to aquatic organisms is spray drift. Differences in spray drift data and its risk to surface water do occur between countries. Available spray drift measurements from the Netherlands, Germany, Belgium, United Kingdom, Sweden and Denmark are collected and analysed to identify the main causes of differences between them and to harmonise information on drift deposition. |
