Results and discussion
Any other information on results incl. tables
Annual average concentrations in wet deposition locations in 21 European countries vary from 0.12 to 1.74 mg NH4+-N/L. In the Netherlands, the mean annual concentration for 1978-1982 was 2.4 mg NH4+-N/L, corresponding to a wet deposition of 12.2 kg/ha per year. The wet deposition inranges from 1.3 – 8.6 kg/ha per year and in thefrom 3.2 to 6.0 kg/ha per year. Wet deposition accounts for only 1/3 of the total deposition of NH3and NH4+. On average, 28.4 kg NH3+ NH4+is deposited per ha per year.
