Emissions to water by the Dutch Agriculture and horticulture target sector, 1990-2001
The emissions of nitrogen and phosphate from agriculture and horticulture continue to fall. Measures taken should cut back the emissions of lead and zinc.

Emissions to water and measures
The emissions of nitrogen and phosphate by agriculture and horticulture continue to fall. Nitrogen and phosphorus emissions are caused by fertiliser being unintentially spread on ditches during fertilising and emissions from agricultural holdings, especially dairy holdings. Run-off and leaching from agricultural land has not been included in the emission data.
Lead emissions are a result of hunting and fishing. The use of lead in hunting munitions is now banned. Stricter measures should also reduce illegal use, which is still widespread. The use of fishing lead will be terminated as soon as an alternative is available.
Emissions of zinc are caused by the corrosion of galvanized steel in greenhouses. To reduce the corrosion and run-off of zinc, agreements have been made with the metals industry about product improvements for the construction industry (VROM, 2001).
