Source identification and size distribution of atmospheric polycyclic aromatic hydrocarbons during rice straw burning period

Overview and Perspectives on Emissions of Polybrominated Diphenyl Ethers on a Global Basis: Evaporative and Fugitive Releases from Commercial PBDE Mixtures and Emissions from Combustion Sources

“…Similar phenomena are observed with PAHs (Cheruiyot et al, 2015). The fate of PAHs is depletion in the combustion in engines due to high PAH contents in gasoline and diesel fuels (Mi et al, 1996;Chang et al, 2014b, c), while PAHs are formed in biomass open burnings (Hays et al, 2005;Yang et al, 2006). Table 4 lists PBDE emission factors of major combustion sources which can be divided into different categories, including waste incinerators, metallurgical processes, power and heating facilities, vehicles, and non-controlled combustion sources.…”

Impact of biomass emissions on particle chemistry during the California Regional Particulate Air Quality Study

“…In Fresno, more than 50% of the fine organic carbonaceous particles are emitted from residential biomass burning in the winter [6,57]. Schauer and coworkers reported that guaiacols, phenols, and their substituted derivatives accounted for approximately 20% of the total mass of semivolatile gas-phase organic compounds emitted from wood combustion [50]; other studies revealed that biomass burning also emits substantial amounts of methoxyphenols and PAHs [58][59][60][61][62]. It is important to note that the ATOFMS is particularly sensitive to these aromatic compounds due to the use of the 266 nm laser.…”

Effects of Burnings of Wax Apple Stubble and Rice Straw on Polychlorinated Dibenzo-p-Dioxin and Dibenzofuran Concentrations in Air and Soil

“…In addition to the deterioration of air quality because of open burning, farmers and nearby residences may have high health risks because of skin exposure, inhalation of toxic byproducts in air, or ingestion of contaminated foods. 12 This study was aimed to measure the concentrations of PCDD/Fs in air, ash, and surface soil before and during burning of residues at two wax orchards and one rice straw field. The results should be helpful for understanding the emission characteristics of PCDD/Fs and their impact on the environments that results from the open burning of agricultural waste.…”
