TLDR
The indoor PM2.5 mass and organic/elemental carbon (OC/EC) during winter and early spring period of 2016-2017 at 68 residential households in four large Chinese cities were studied, indicating the presence of carbonaceous aerosols and the limited influence from indoor sources.About:

Junyao Li,Weiqi Xu,Zhijie Li,Minzheng Duan,Bin Ouyang,Shan Zhou,Lu Lei,Yao He,Jiaxing Sun,Zifa Wang,Lin Du,Yele Sun +11 more
TL;DR: In this paper, the authors conducted real-time online measurements of mass concentrations and chemical composition of black carbon and the non-refractory species in PM2.5 in an occupied office for approximately one month.

Impact of daily household activities on indoor PM2.5 and Black Carbon concentrations in Malta
TL;DR: In this paper, the influence of different household activities on the indoor PM2.5 and BC levels were also analysed. And the activities resulting in elevated indoor concentrations included sweeping, cooking (not grilling and frying), grilling, and frying and burning of candle and incense sticks.

Temporal Variation and Source Analysis of Carbonaceous Aerosol in Industrial Cities of Northeast China during the Spring Festival: The Case of Changchun
TL;DR: In this paper, the authors monitored the concentrations of carbonaceous aerosols (OC and EC) in Changchun during the Lunar New Year of 2018 (i.e., from Lunar 20 December to Lunar 20 January), and analyzed the temporal variation and source contributions via the hybrid-single particle Lagrangian Integrated Trajectory (HYSPLIT) model with the potential source contribution factor weights (PSCF) method.

TL;DR: Fine particulate and sulfur oxide--related pollution were associated with all-cause, lung cancer, and cardiopulmonary mortality and long-term exposure to combustion-related fine particulate air pollution is an important environmental risk factor for cardiopULmonary and lung cancer mortality.

TL;DR: The results suggest that, in addition to mitigating primary particulate emissions, reducing the emissions of secondary aerosol precursors from fossil fuel combustion and biomass burning is likely to be important for controlling China’s PM2.5 levels and for reducing the environmental, economic and health impacts resulting from particulate pollution.

TL;DR: In this paper, simultaneous measurements of atmospheric organic and elemental carbon (OC and EC) were taken during winter and summer seasons at 2003 in 14 cities in China, and PM2.5 samples were analyzed for OC and EC by the Interagency Monitoring of Protected Visual Environments (IMPROVE) thermal/optical reflectance protocol.
