Abstract
Ground-level ozone (O3) is a key atmospheric constituent participating in many important atmospheric reactions, and has many negative effects both on human health and the environment. We have measured O3 ambient concentrations in four Czech rural areas of great natural value: the Orlicke hory Mts., Novohradske hory Mts., Česke Švycarsko and Jizerske hory Mts. For our measurement we used Ogawa diffusive samplers. The measurements were carried out during the vegetations seasons of 2004–2010, the samplers were exposed for two-weeks periods and the filters analyzed in the CHMI laboratory. The aim of this paper is to summarize the experience we have of using the diffusive sampling method in the field.
Highlights
Ground-level ozone (O3) is a key component of the atmosphere
As a potent oxidant and a source of the OH radical, it plays an important role in atmospheric chemistry, removing many air pollutants from the atmosphere by oxidation reactions (Seinfeltd and Pandis 1998)
The aim of this paper is to summarize the experience we obtained using diffusive samplers, which might be useful for researchers using these measurements
Summary
As a potent oxidant and a source of the OH radical, it plays an important role in atmospheric chemistry, removing many air pollutants from the atmosphere by oxidation reactions (Seinfeltd and Pandis 1998). O3 has negative effects both on human health, ecosystems and the environment (Royal Society 2008). It is still considered to be the most important air pollutant (Paoletti et al 2010). Ozone is a criteria pollutant and there are legal limit values for human health, vegetation and ecosystem protection (Hůnová 2003), and regular monitoring of concentrations of ambient O3 is required. In Europe, the limit values for O3 are extensively exceeded (EEA 2016), and with regard to ambient air pollution, O3 is considered, together with aerosol, as the major threat
