Impacts of air pollution and meteorological conditions on dry eye disease among residents in a northeastern Chinese metropolis: a six-year crossover study in a cold region.

The purpose of this study is to explore the associations among dry eye disease (DED), air pollution, and meteorological conditions in the cold region of a northeastern Chinese metropolis (i.e., Changchun).

Seasonal variation in surface ozone and its regional characteristics at global atmosphere watch stations in China.

We investigated the seasonal and spatial ozone variations in China by using three-year surface ozone observation data from the six Chinese Global Atmosphere Watch (GAW) stations and tropospheric column ozone data from satellite retrieval over the period 2010-2012. It is shown that the seasonal ozone variations at these GAW stations are rather different, particularly between the western and eastern locations. Compared with western China, eastern China has lower background ozone levels.

Fine particulate air pollution and daily mortality in Shenyang, China.

Fine particulate matter (PM₂.₅) is not a criteria pollutant in China, and few studies were conducted in the country to investigate the health impact of PM₂.₅.

[Responses of subtropical conifer plantation to future climate change: a simulation study].

The responses of subtropical conifer plantation to climate change scenarios were investigated in Qianyanzhou by the process-based physiological-ecological model EALCO (ecological assimilation of land and climate observation). The results showed that CO2 concentration had the greatest effects on the carbon and water fluxes of the plantation, followed by temperature, and precipitation. CO2 concentration was the main driving factor for the gross photosynthesis productivity of this plantation ecosystem, and temperature and CO2 concentration were the key environmental factors controlling the ecosystem respiration.
