[Quantification of Ozone Pollution Transport Based on Four-dimensional Flux Method in Foshan, China].

Quantifying the contribution of transport processes to air pollution events has been a prominent challenge and an important need in regional air pollution prevention and control. The WRF-Chem model was used to simulate a typical regional ozone (O) pollution event in Foshan, and the four-dimensional flux method was applied to quantify the transport fluxes of ozone and its precursors from the surrounding areas to Foshan and to clarify the contributions of the direct transport of ozone and transport of precursors. The average ozone flux from the surrounding areas to Foshan was 120.

[Pollution Characteristics of Non-methane Hydrocarbons During Winter and Summer in Foshan City].

Thirty non-methane hydrocarbons(NMHCs) samples were collected and analyzed in Foshan City during winter 2014 and summer 2015. The concentrations of NMHCs during the sampling period were 122.30 μg·m and 56.

Impacts of Atmospheric Mercury Deposition on Human Multimedia Exposure: Projection from Observations in the Pearl River Delta Region, South China.

A preliminary projection was performed to determine human multimedia exposure to mercury (Hg) based on deposition flux observations and to identify the impacts of atmospheric Hg deposition in Pearl River Delta (PRD) region, South China. The Monte Carlo technique was used to propagate the variability throughout the projection. The regional specific probability density functions (PDFs) of the studied parameters were regressed from the provincial/national published data, except when the data were deficient.

Long-term trends of chemical characteristics and sources of fine particle in Foshan City, Pearl River Delta: 2008-2014.

Foshan is a major international ceramic center and the most polluted city in the Pearl River Delta (PRD). Here we present the results of the first long-term PM2.5 (particles <2.
