Nitrogen deposition and its impacts on the ecosystems are dealt with by the UNECE

Task Force on Mapping The outcome of this work will form the main basis for the

new nitrogen protocol. Abatement strategies as discussed for the new NOx protocol,

should take into account all aspects of air pollution. A complete assessment has not

yet been carried out of which pollutants and which effects will require the most farreaching

reductions in different European regions in order to protect health,

ecosystems and materials. The new NOx protocol will mainly address the impacts of

O3 formation and deposition of nitrogen compounds, while the FWD will mainly

address direct human health air exposure. The Nitrogen Oxides Protocol, under the

UNECE Convention of Long-range Transboundary Air Pollution, is signed by 26

countries. It commits signatories to ensure that 1994 NOx emissions do not exceed

those in 1987. In addition, a number of countries committed themselves, to reduce

their emissions by 30%. However, the majority of these countries are unlikely to

achieve their targets. As can be seen in Table 1.2, few countries have reduced

emissions more than 20%. A new nitrogen protocol is under preparation and

negotiations are expected to begin during 1997. All effects of NOx including human

health will be considered. Since many environmental effects, caused by nitrogen

compounds are also caused by other pollutants, these other pollutants will also be

considered producing a multi-pollutant, multi-effect protocol.
