Ozone measurements in Europe

, : Ozone measurements in Europe. Water Air & Soil Pollution 85(4): 1949-1954

Ozone measurements have been a part of EMEP since its third phase in 1984-1986 and since 1988 data have be-en collected systematically. By 1992 data for 76 sites were being collected by the Chemical Co-ordinating Centre in NILU. The mean ozone concentration increases from 20-25ppb in the western and northern fringes to 30-35 in central areas of Europe. There is also evidence from the last decade of an upward trend of up to 0.5ppb y-1 at rural sites in the UK. The data have been analysed to estimate the spatial patterns in AOT 40 for ozone effects on crops and forests. The data show that the critical level for cereal crops of 5300 ppb.h above a threshold of 40 ppb is exceeded over almost all of continental Europe south of 65 degree N and over most of S.Britain. A similar exercise for the AOT 40 for the forest again shows exceedances of the critical load of 10-4 ppb.h across all the mapped area of Continental Europe south of 65 degree N including S.Britian. As land use for forestry and ozone dose both increase with altitude, and these effects have not so far been incorporated in the AOT 40 assessment for forests, the degree of exceedence for forests may have bee significantly under-estimated.

Coincidence counting techniques have been combined with time-of-flight mass spectrometry in the examination of surfaces for chemical microhomogeneity. A mathematical formalism was developed to describe the principles underlying this coincidence co...

The river Elz has its origin in the Black Forest and is later flowing towards the Upper Rhine floodplain (Southwest Germany). The chironomid fauna was investigated in the year 2003 by using chironomid pupal exuvie. 158 species were identified. Cor...

In this contribution we review our recently developed method for the calculation of acidity constants from density functional theory based molecular dynamics simulations. The method is based on a half reaction scheme in which protons are formally...

This paper discusses climate, land, energy and water (CLEW) interactions in Burkina Faso. It shows that integrated assessments of resource use at the national level can provide important insights and benefits, especially for a resource constrained...

In contrast, expression of IL-8 in these same cells is virtually absent in the unstimulated state, de...
