Research over the past ten years has created a more detailed and coherent view of the relation between O 3 and its major anthropogenic precursors, volatile organic compounds (VOC) and oxides of nitrogen (NO x ). This article presents a review of insights derived from photochemical models and field measurements. The ozone—precursor relationship can be understood in terms of a fundamental split i...

The indoor air quality is much more matter of concern as relative to ambient or outdoor air quality, especially in the context of human health.  However, very few studies have been reported for remediation of indoor ozone by plant species. The main objective of this study is to evaluate ozone deposition velocities and ozone removal effectiveness of three indoor ornamental plant species (Dra...

Addition of H202 has been employed to repress bromate formation during ozonation of bromide-containing source water. However, the addition of H2O2 will change the oxidation pathways of organic compounds due to the generation of abundant hydroxyl radicals, which could affect the removal efficacy of trihalomethane precursors via the combination of ozone and biological activated carbon (O3-BAC). I...

To explore the relationship between tropospheric ozone and radiative forcing with changing emissions, we compiled two sets of global scenarios for the emissions of the ozone precursors methane (CH4), carbon monoxide (CO), non-methane volatile organic compounds (NMVOC) and nitrogen oxides (NOx) up to the year 2030 and implemented them in two global Chemistry Transport Models. The “Current Legisl...

Abstract Background This review updates a systematic published in 2010 ( http://www.environmentalevidence.org/completed-reviews/how-effective-is-greening-of-urban-areas-in-reducing-human-exposure-to-ground-level-ozone-concentrations-uv-exposure-and-the-urban-heat-island-effect ) which addressed the question: How effective is ‘greening’ of urban areas reducing human exposure to ground-level ozon...

Background & Aims of the Study: Ozone is a summer pollutant which can cause respiratory complications, eye burning sensation and failure of immune defense against infectious diseases. Ahvaz city (southwestern Iran) is one of the seven polluted Iranian metropolises. In this study we examined the health impacts of ozone pollution in Ahvaz city during years 2010 and 2011. Ma...

Abstract. China has experienced dramatic changes in emissions since 2010, which accelerated following the implementation of Clean Air Action program 2013. These have resulted significant air quality improvements that are reflected observations from both surface networks and satellite observations. pollutants, such as PM2.5, ozone, their precursors, long enough lifetimes troposphere to be easily...
