“…A review of the literature found limitation of studies primarily focused on analyzing the ozone exceedances in the HGB area due to different source categories. Individual studies have been performed concentrating on high level of ozone concentrations due to different industrial sources (petrochemical industries, electricity generation facilities), biogenic sources, effects of different meteorological parameters, as well as local and regional transport of ozone [13]. There exists a considerable gap in the literature regarding contribution of different source categories on the high level of ozone concentrations in the HGB area.…”

The goal of this study is to analyze the relative contribution of different emission source categories to ozone in the Houston-Galveston-Brazoria (HGB) area of Texas. Emission Processing System (EPS3) is used to prepare the emission files for five different source combination cases (Base case, Biogenic, Area + Biogenic, Mobile + Biogenic, Low-level Point + Biogenic). These emission files are used to perform photochemical modeling with Comprehensive Air Quality Model with Extensions (CAMx), and the results are analyzed with Visual Environment for Rich Data Interpretation (VERDI) tool. The daily maximum ozone concentrations and individual contributions of the source categories were analyzed over a 15-day study period between June 1-15, 2012, at three locations (University of Houston-Sugarland, Bayland Park and Conroe). Biogenic sources contributed an average of 49.7% ± 12.8%, 43.1% ± 12.0%, and 39.9% ± 9.28% at Sugarland, Bayland Park and Conroe sites respectively, indicating the significance of isoprene emissions from the vegetation in northeast Houston. On peak ozone days, contribution of Mobile + Biogenic source category averages about 80.1% ± 12.6%, 79.9% ± 6.50%, and 75.9% ± 10.9% at Sugarland, Bayland Park and Conroe sites respectively, indicating the dominance of mobile source NO X emissions and the necessity for regulatory focus on mobile source emissions control.

Troposphere ozone, which is from secondary formation processes, has been increasing dramatically during the last decades in China, inducing high health risks. In this study, temporal and spatial distribution of O was studied among 13 sites of three cities during 2014-2016. The objectives were to clarify the characteristics of the ambient pollution of O under the influence from other pollutants and meteorological parameters and the health outcomes from exposure to O. The concentrations of O during summer were much higher than those during winter, and the concentrations in downtown areas were higher than in rural or mountain areas. PM, NO, SO, and wind speed (WS) were negatively correlated with O, and CO, temperature (T), and relative humidity (RH) were positively correlated with O. In multivariable analysis, two separate factors-solar radiation and atmospheric diffusion status, affected the O levels. The concentrations of O reached the highest level at 15:00 and the lowest value at about 6:00-8:00, with the similar trend to T and WS, and opposite to RH. According to the dose-response model, relative risks (RRs) and population attributable fractions (PAFs) with confidence intervals (CIs) for chronic obstructive pulmonary disease (COPD) from exposure to O were 1.0612 (CI 1.0607-1.0616) and 5.32% (CI 5.29-5.36%), respectively, attributable to 2000 deaths in Zhejiang Province in 2014.
