The continuous measurement of nitric oxide (NO), nitrogen dioxide (NO2), oxides (NOx) and ozone (O3) was conducted in Tianjin from September 8 to October 15, 2006. data were used investigate the relationship between O3 distribution its association with ambient concentrations NO, NO2 NOx (NO NO2). measured pollutants study area varied as a function time, while peaks all occurred succession daytime. diurnal cycle ground-level concentration showed mid-day peak lower nighttime concentrations....
This paper describes the fabrication of two different 3D mesoporous TiO2 microspheres via one-step solvothermal process without templates using titanium sources. The resulting materials were characterized by XRD, FESEM, TEM, and nitrogen adsorption techniques. Their photodegradation bisphenol A [2,2-bis(4-hydroxyphenyl)propane, BPA] in aqueous suspension was investigated under UV irradiation. experimental results revealed that photocatalytic effect superior to commercial P25 TiO2,...
Factor analysis utilizes the covariance of compositional variables to separate sources ambient pollutants like particulate matter (PM). However, meteorology causes concentration variations in addition emission rate changes. Conventional positive matrix factorization (PMF) loses information from data because these dilution variations. By incorporating ventilation coefficient, dispersion normalized PMF (DN-PMF) reduces effects. DN-PMF was applied hourly speciated composition a field campaign...
Acidity (pH) plays a key role in the physical and chemical behavior of PM2.5. However, understanding how specific PM sources impact aerosol pH is rarely considered. Performing source apportionment PM2.5 allows unique link from polluted city. Hourly water-soluble (WS) ions were measured online December 25th, 2014 to June 19th, 2015 northern city China. Five resolved including secondary nitrate (41%), sulfate (26%), coal combustion (14%), mineral dust (11%), vehicle exhaust (9%). The influence...
Many places on earth still suffer from a high level of atmospheric fine particulate matter (PM2.5) pollution. Formation pollution event or haze episode (HE) involves many factors, including meteorology, emissions, and chemistry. Understanding the direct causes key drivers behind HE is thus essential. Traditionally, this done via chemical transport models. However, substantial uncertainties are introduced into model estimation when there significant changes in emissions inventory due to...
The purpose of this study is to characterize heavy metals in ambient PM10 (particles with aerodynamic diameter below 10 µm) and PM2.5 2.5 particles a typical integrated iron steel industry zone (HG) background site (ZWY) during February 2011 January 2012 the Yangtze River Delta (YRD) region, China. Twelve elements were measured their levels, size distribution sources. At two sampling sites, Fe was found as dominated metal total detected both particle sizes, followed by Zn Pb. They regarded...
Abstract. To quantify the total, direct and indirect impacts of fireworks individually, size-resolved PM samples were collected before, during after a Chinese folk festival (Chinese New Year) in megacity China. Through chemical analysis morphological characterisation, strong influence on physicochemical characteristics PM10 PM2.5 was observed. The concentrations many species exhibited an increasing trend heavy-firework period, especially for K+, Mg2+ Cr; results non-sea-salt ions...
