The influence of second-generation products on the particle mass yield of β-caryophyllene ozonolysis was systematically tested and quantified. The approach was to vary the relative concentrations of firstand secondgeneration products by adjusting the concentration of ozone while observing changes in particle mass yield. For all wallloss corrected organic particle mass concentrations Morg of thi...

Abstract Atmospheric warming and increasing tropospheric ozone (O3) concentrations often co-occur in many cities of the world including China, adversely affecting health status urban trees. However, little information is known about combined interactive effects from increased air temperature (IT) elevated O3 (EO) exposures on tree species. Here, Ginkgo biloba Populus alba ‘Berolinensis’ seedlin...

Background and Purpose: Ozone is an inorganic molecule with effective antimicrobial properties. Clinical treatment of ozonated water was used for the elimination of Candida albicans, Enterococcus faecalis, endotoxins, and biofilms from root canals. In addition, its therapeutic effects for tinea pedis, ulcers, and leishmaniasis were investigated. The purpose of the present study was to evaluate ...

While the negative impacts of air pollution on human productive capacity and health have long been studied in both laboratory and ambient exposure settings, the majority of research has focused on the e ects of acute, single-period exposures on at-risk populations. This study signi cantly expands this scope through an examination of the e ects of low-level, ambient ozone exposure in both the pr...

A number of epidemiological studies have attempted to assess the effect of recurrent ozone exposure in humans. For the most part, they have failed to document convincingly an association between chronic ozone exposure and differences in lung function performance or respiratory symptoms. This is not surprising given the small respiratory effects observed in animals chronically exposed to ozone a...

BACKGROUND Air pollution is a major risk factor for cardiovascular disease, of which ozone is a major contributor. Several studies have found associations between ozone and cardiovascular morbidity, but the results have been inconclusive. We investigated associations between ozone and changes across biological pathways associated with cardiovascular disease. METHODS Using a panel study design...

BACKGROUND Studies have explored ozone's connection to asthma and total respiratory emergency department visits (EDVs) but have neglected other specific respiratory diagnoses despite hypotheses relating ozone to respiratory infections and allergic responses. OBJECTIVE We examined relationships between ozone and EDVs for respiratory visits, including specifically acute respiratory infections (...

Northern red oak (Quercus rubra L.) seedlings and trees differ in their response to ozone. Previous work reported reductions in net photosynthesis, carboxylation efficiency and quantum yield of mature tree leaves, whereas seedling processes were unaffected by the same ozone exposure. To further characterize differences in ozone response between seedlings and mature trees, we examined carbon par...
