OBJECTIVE Because the state of the atmosphere determines the development, transport, dispersion, and deposition of air pollutants, there is concern that climate change could affect morbidity and mortality associated with elevated concentrations of these gases and fine particles. We review how climate change could affect future concentrations of tropospheric ozone and particulate matter (PM), an...

[1] The international field experiment Pianura Padana Produzione di Ozono (PIPAPO) studying the volatile organic compounds (VOC)/NOx ozone production sensitivity took place in May and June 1998 downwind of the metropolitan area of Milan. The project was embedded in the framework of the EUROTRAC-2 Limitation of Oxidant Production (LOOP) subproject. Several ground stations between the city of Mil...

This paper presents a study of societal costs related to public health due to the degradation of air quality and the lack of physical activity, both affected by our built environment. The paper further shows road safety as another public health concern. Traffic fatalities are the number one cause of death in the world. Traffic accidents result in huge financial loss to the people involved and t...

When drinking water treatment plants disinfect water, a wide range of disinfection by-products (DBPs) of health and regulatory concern are formed. Recent studies have identified emerging DBPs (e.g. iodinated trihalomethanes (THMs) and acids, haloacetonitriles, halonitromethanes (HNMs), haloacetaldehydes, nitrosamines) that may be more toxic than some of the regulated ones (e.g. chlorine- and br...

Volatile organic compounds (VOCs) were monitored online at three photochemical assessment monitoring stations (MDS, WQS and HGS) in the Pearl River Delta region during summer of 2016. Measured levels VOCs MDS, HGS sites 34.78, 8.54 8.47 ppbv, respectively, with aromatics alkenes as major ozone precursors to secondary aerosol (SOA). The positive matrix factorization (PMF) model revealed that mai...

Abstract. Ozone formation regimes are closely related to the ratio of volatile organic compounds (VOCs) NOx. Different ranges HCHO/NO2 indicate three regimes, including VOC-limited, transitional, and NOx-limited regimes. Due unstable interactions between a diversity precursors, range transitional regime, which plays key role in identifying ozone remains unclear. To overcome uncertainties from s...

Climate change plus ozone pollution is a lethal combination that adversely affects human health, agriculture productivity, ecosystems, and the world economy. Currently, there growing concern climate may aggravate even after reducing anthropogenic precursor source activities. Part of it be due to temperature-enhanced natural emissions ozone, increased stratospheric–tropospheric exchange more fre...

Changes in proximate composition, colour and textural characteristics of ozone-processed shrimp as affected by combined effects of increasing ozone exposures and iced storage were investigated and for the first time. Whilst proximate composition comprised of fat, moisture, and protein contents and colour comprised of L*, a*, b* and metric chroma (C), the texture comprised of adhesiveness, fract...
