Short-term chronic and acute aquatic bioassays are valuable tools in screening a variety of environmental samples. However, only a limited number of studies have used these methods for testing the toxicity of atmospheric particulate matter samples. Previous studies have shown that compounds known to have adverse biological effects, such as polycyclic aromatic hydrocarbons, are deposited in sign...

Abstract. Condensable particulate matter (CPM) emitted from stationary combustion and mobile sources exhibits high emissions a large proportion of organic components. However, CPM is not generally measured when conducting emission surveys PM in most countries, including China. Consequently, previous inventories have included rates for CPM. Here, we construct an inventory China with focus on aer...

A long-standing enigma in oceanography is why terrestrial organic matter “missing” the global ocean, despite considerable discharge into it every year. Although some explanations, such as mineralogical composition, hydrodynamic processes, and priming effect, have been proposed, we hypothesize that essential mechanism behind missing microbial processing, for which underlying coupled geochemical,...

Airborne suspended particulate matter is an important marker of air quality. The term 'particulates' includes organic and inorganic matter, nitrogen compounds, sulphur compounds, polycyclic aromatic hydrocarbons (PAHs), several heavy metals, and radionuclides. The health risks from the 'classic' pollutants sulfur dioxide, nitrogen dioxide, ozone, carbon monoxide, and particulates have been comp...

conclusions in order to diminish the health impacts of particulate matter in khorramabad, health training for the public, especially for persons with chronic lung and heart diseases, the elderly, and children, should be conducted by health systems to encourage them to reduce their activities during dusty days. materials and methods the pm10 sampling was carried out with a high-volume sampler at...
