Potatoes (Solanum tuberosum cv. ‘Hela’) were exposed in closed fumigation chambers for nine weeks until harvest in 1995. In three treatments ozone was applied as constant concentration (35 ppb for 24 h/d) as well as with peaks (110 ppb for 4 h/d and 65 ppb for 8 h/d) under equal dose conditions. In addition ozone was applied at constant concentration (47, 65 ppb for 24 h/d) in two treatments. I...

We use regional air quality modeling to evaluate the impact of model resolution on uncertainty associated with the human health benefits resulting from proposed air quality regulations. Using a regional photochemical model (CAMx), we ran a modeling episode with meteorological inputs simulating conditions as they occurred during August through September 2006 (a period representative of condition...

Most often the contaminants are not taken seriously into consideration, and this behavior comes out directly from the lack of monitoring and professional reporting about pollution in the printing facilities in Serbia. The goal of planned and systematic ozone measurements in ambient air of the screen printing facilities in Novi Sad is to examine of its impact on the employees health, and to trac...

Air pollution is increasingly recognized as an important and modifiable determinant of cardiovascular diseases in urban communities. The potential detrimental effects are both acute and chronic having a strong impact on morbidity and mortality. The acute exposure to pollutants has been linked to adverse cardiovascular events such as myocardial infarction, heart failure and life-threatening arrh...

Ozone (O3) has attracted much attention because of its key role in human health and disease, and its detection is of great importance for various biochemical studies as well as environmental evaluation. Here we develop a simple and practical spectroscopic off-on O3 probe based on resorufin and the specific reaction of but-3-enyl with O3. The probe shows an extremely low background spectroscopic...

UV radiation is an essential driver for the formation of photochemical smog, which includes ground-level ozone and particulate matter (PM). Recent analyses support earlier work showing that poor outdoor air quality is a major environmental hazard as well as quantifying health effects on regional and global scales more accurately. Greater exposure to these pollutants has been linked to increased...

The state-of-the-art progress on unconventional technologies and materials for the enrichment of low concentration ventilation air methane is critically analyzed overviewed.

Drawn from multiple reanalysis datasets, an increasing trend and westward shift in the number of Potential Vorticity intrusion events over the Pacific are evident. The increased frequency can be linked to a long-term trend in upper tropospheric equatorial westerly wind and subtropical jets during boreal winter to spring. These may be resulting from anomalous warming and cooling over the western...
