To reduce air pollution, China adopted rigorous control mechanisms and announced the Air Pollution Prevention Control Action Plan (APPCAP) in 2013. Here, using OMI satellite, NASA Socioeconomic Data Application Center (SEDAC), Fifth ECMWF (ERA5) data at a 0.25° × resolution, we explored changes NO2, PM, SO2, O3 climatology over response to between 2004 2021. This study attempts investigate long...
the present study aimed at evaluating the effect of aerobic exercise in carbon black particulates air pollution on tlr4 and tnf-α gene expression in male rats. 24 male wistar rats (mean body mass 279.29+26.97 gr) were randomly divided into 4 groups: a) control, b) aerobic exercise, c) pollution, d) exercise+pollution. a particulates injector and falounak chamber were used to expose the rats to ...
The responses of pine forest to changing climate and environmental chemistry were studied along two transects following the pollution and continentality gradients in Poland. One axis begins on the western border of Poland, crosses the country along the 52nd parallel, and ends on the eastern border of Poland in the area of Bialowieza National Park, Biosphere Reserve. The second axis begins in in...
BACKGROUND Prolonged high temperatures and air pollution from wildfires often occur together, and the two may interact in their effects on mortality. However, there are few data on such possible interactions. METHODS We analyzed day-to-day variations in the number of deaths in Moscow, Russia, in relation to air pollution levels and temperature during the disastrous heat wave and wildfire of 2...
Exposure to high levels of environmental air pollution is known to be associated with an increased carcinogenic risk. The individual contribution to this risk derived from specific carcinogenic chemicals within the complex mixture of air pollution is less certain, but may be explored by the use of molecular epidemiological techniques. Measurements of biomarkers of exposure, of effect and of sus...

Boundary environmental pollution and pollution spillovers are important issues for improving the water quality of trans-boundary rivers. This paper explores the empirical effects of the evolution of the pollution reduction mandates on boundary pollution by studying the change of water pollution levels (as proxied by pH, BOD, COD and NH3-N) of key state monitoring stations from 2004 to 2014. The...
The aim of this study was to estimate the population burden of respiratory diseases in the Zasavje region of Slovenia that can be attributed to outdoor air pollution in order to gain relevant grounds for evidence based public health activities. In 2008, 981 schoolchildren (age 6 to 12 years) were observed in a prevalence study. The prevalence of chronic respiratory diseases (CRD) and frequent a...
[1] During the Asian Pacific Regional Aerosol Characterization Experiment (ACE-Asia), samples of carbonaceous aerosols were collected on board the Center for Interdisciplinary Remotely Piloted Aircraft Studies (CIRPAS) De Havilland DHC-6 Twin Otter aircraft. The samples were analyzed to determine their total carbon (TC) and water-soluble organic compound (WSOC) contents as well as to identify t...
