Chemical Analysis of Fine Particulate Matter: PM 2.5μg/m3 and PM 10μg/m3, in Cities: Prishtinë, Fushë Kosovë, and their Correlation between Pollutant Emission from TC “Kosovo”

Hormesis for fine particulate matter (PM 2.5).

The hypothesis of hormesis - that substances that harm health at high exposures can reduce risks below background at low exposures, e.g., if they activate defenses without overwhelming them - becomes important for practical policy making if it holds for regulated substances. Recently, the U.S. EPA concluded that reductions in ambient concentrations of fine particulate matter (PM2.5) in air caus...

Impairment of mitochondrial function by particulate matter (PM) and their toxic components: implications for PM-induced cardiovascular and lung disease.

Increasing evidence suggests that reactive oxygen species (ROS) and oxidative stress are involved in PM-mediated lung and cardiovascular injury. The physical characteristics and the chemical composition of particulate matter (PM) play a key role in ROS generation in vitro and in vivo. The mitochondria are major subcellular targets for PM as well as a source of ROS production. ROS production is ...

Wintertime vertical variations in particulate matter (PM) and precursor concentrations in the San Joaquin Valley during the California Regional Coarse PM/Fine PM Air Quality Study.

Air quality monitoring was conducted at a rural site with a tower in the middle of California's San Joaquin Valley (SJV) and at elevated sites in the foothills and mountains surrounding the SJV for the California Regional PM10/ PM2.5 Air Quality Study. Measurements at the surface and n a tower at 90 m were collected in Angiola, CA, from December 2000 through February 2001 and included hourly bl...

Short-term effect of fine particulate matter (PM₂.₅) and ozone on daily mortality in Lisbon, Portugal.

INTRODUCTION Urban ambient air pollution exposures continue to be a global public health concern. Although air quality targets are often exceeded in Lisbon, the largest city in Portugal, there is currently no study that has assessed the quantitative impact of these pollutants on daily mortality. MATERIALS AND METHOD In this study, we conduct a time series analysis using generalized additive m...
