PAHs in Chinese atmosphere: Gas/particle partitioning

Spatial distribution of pollution characteristics and human health risk assessment of exposure to heavy elements in road dust from different functional areas of Zhengzhou, China

“…Atmospheric environmental pollution in urban areas has gained considerable attention from scholars and scientific researchers in recent decades, since it is closely relevant to people's daily lives and traffic and causes severe harm to the human body and low visibility (Liu et al 2019). Studies of the content of fine particulate matter (PM2.5) (Cooper et al 2019;Wang et al 2020), organic contaminants, such as polycyclic aromatic hydrocarbons (PAHs) (Ma et al 2019;Škrbić et al 2019;Wang et al 2016b), polybrominated diphenyl ethers (PBDEs) (Chou et al 2019), and phthalate esters (PAEs) (He et al 2019;Škrbić et al 2016), and heavy metals (HM) (Cai et al 2019;Lanzerstorfer and Logiewa 2019), such as zinc, lead, nickel, and cadmium, have been used for Responsible Editor: Philipp Gariguess Electronic supplementary material The online version of this article (https://doi.org/10.1007/s11356-020-08942-7) contains supplementary material, which is available to authorized users. measuring air pollution.…”

Polycyclic Aromatic Hydrocarbons in Atmospheric PM2.5 during Winter Haze in Huang-gang, Central China: Characteristics, Sources and Health Risk Assessment

“…Because of the lack of gas-PAHs concentration data, the G/P distribution model is introduced to estimate PAHs in gas phase to assess the carcinogenic risk more accurately. The distribution model has been described in detail in previous study (Ma et al, 2019), and the equation is as following:…”

Atmospheric Chemistry Analysis: A Review

“…The coexistence of particle and gas phases of semivolatile organic compounds, such as PAHs, in the atmosphere presents sampling challenges, due to the dynamic nature thereof and the ease with which the equilibrium can be disturbed. Effective and efficient sampling of each phase simultaneously is critical, however, in order to understand atmospheric chemistry processes and potential impacts of the target analytes. , Some samplers are prone to sampling artifacts, have unpredictable sampling efficiencies, or are not able to adequately differentiate between phases. Verification of particle transmission through gas phase denuder samplers is important in this regard .…”
