Multi-model Assessment of Tropospheric Ozone Pollution Indices of Risk to Human Health and Crops, and Ozone Deposition in Ciuc Depression Romania

Abstract:

The Greenhouse Gas and Air Pollution Interactions and Synergies (GAINS) model quantified the relationship between the premature mortality and the long-term troposphere ozone concentration. Researches show that the elevated surface ozone concentration has an adverse impact on human health and vegetation also. In the present paper we examine the effect of ozone concentration with different indicators. Among the indicators on vegetation we examine the AOT40 and the W126. The limit values for these indicators according to the UNECE and the EU (2010) are 5000 ppb and 6000 ppb. The values of the indicators reported on Ciuc Basin ozone concentrations (AOT40, W126) does not cross the limits, but if we examine them in connection with the human health, it turns out that they exert an influence on the mortality. During the examination of the climate penalty factor a significant ozone increase can be reported in case of a possible temperature rise. This phenomenon is in accordance with the rate of mortality. The deterioration of the vegetation is caused by the ozone deposition, which may occur in dry or wet conditions. In this case we examine the wet deposition in relation with the coniferous woods of the Ciuc basin. Our results worked out in accordance with the ozone concentration indicators (AOT40, W126).
