Abstract

Ground-level or tropospheric ozone (O3) is an oxidant air pollutant that has harmful effect on human health and vegetation, however, it is a short-lived greenhouse gas. Ozone is a secondary pollutant; which means that it is not directly emitted in the ambient air, but also produced from the photochemical oxidation of non-methane volatile organic compounds (NMVOCs), methane (CH4), or carbon monoxide (CO) in the presence of nitrogen oxides (NOx). It is destroyed both photochemically and through deposition to the surface. Summarizing the chemistry of ozone is complex and non-linear. Background concentrations of ground-level ozone in Europe do not show a significant downward trend, but in Hungary essential reduction (–0.28 μg/m3) was observed at Kpuszta station in the last decades. In the monthly distribution the amplitude decrease with increase in altitude, at K-puszta 45.1 μg/m3, while at Nyírjes 36.6 μg/m3 amplitudes were observed. Based on our data we found that the ozone gradient is about +1.4 μg/m3/m. Breathing ozone can result in a number of negative health effects that are observed in relevant segments of the population. Ozone also is known as the air pollutant most damaging to agricultural crops and other plants. This article gives a general overview of the ozone problem focusing on the Hungarian specialties.
