STUDY ON THE NEED FOR AN NO-2 LONG-TERM LIMIT VALUE FOR THE PROTECTION OF TERRESTRIAL AND AQUATIC ECOSYSTEMS
The report gives results on the following issues which have been studied in order to examine the question if a long-term limit value for NO is needed: (i) The effects of NO-2 as a single compound on vegetation, (ii) The effects on vegetation of NO-2 in combination with other pollutants, (iii) The contribution of NO-2 to effects on soils, (iv) The effects of NO-2 on aquatic ecosystems, (v) The effects of secondary pollutants, in particular photochemical oxidants, which are created in processes involving NO-2, on vegetation, (vi) The need to lay down a long-term limit value for administrative and air quality management purposes, (vii) The consequences of a long-term limit value for the production of photochemical oxidants, (viii) The consequences of such a value for emission reduction measures and monitoring. Therefore, the study group concluded that at present no long-term limit value for NO-2 can be proposed.
