The levels of four sets pollutants (heavy-metals, artificial radionuclides, petroleum components, and halogenated hydrocarbons), have been measured in U.S. coastal waters, using bivalves as sentinel organisms. strategies carrying out this programme are outlined the results from first year's work given. Varying degrees pollution waters indicated by elevated bivalves, which comprised certain species mussels oysters were collected at over one hundred localities.
Abstract. Wildfires in Siberia generate large amounts of aerosols, which may be transported over long distances and pose a threat to the sensitive ecosystem Arctic. Particulate matter (PM) aged wildfire plumes originating from Yakutia August 2021 was collected Nadym on Bely Island (both northwestern Siberia). An advanced analysis chemical composition aerosol particles conducted through multi-wavelength thermal–optical carbon analyzer (TOCA) coupled resonance-enhanced multiphoton ionization...
A series of sensitivity experiments are conducted in an attempt to understand and correct deficiencies the simulation seasonal mean Indian monsoon with a global atmospheric general circulation model. The precipitation is less than half that observed. This poor integrations independent choice initial conditions sea surface temperature data used. Experiments performed test changes orography, vegetation, soil wetness, cloudiness. authors find deficiency model may be attributed use enhanced...
The health effects of exposure to secondary organic aerosols (SOAs) are still limited. Here, we investigated and compared the toxicities soot particles (SP) coated with β-pinene SOA (SOAβPin-SP) SP naphthalene (SOANap-SP) in a human bronchial epithelial cell line (BEAS-2B) residing at air–liquid interface. SOAβPin-SP mostly contained oxygenated aliphatic compounds from photooxidation, whereas SOANap-SP significant fraction aromatic products under similar conditions. Following exposure,...
Air pollution over Lake Baikal originating from anthropogenic emissions as well wildfire events and secondary organic aerosol (SOA) formation poses a threat to this world heritage ecosystem. During ship expedition in 2018, ambient particles were sampled on filters at different locations of extracted obtain the fraction water-soluble (WSOA). Subsequent analysis by Fourier transform ion cyclotron resonance (FTICR) mass spectrometry with direct-infusion electrospray ionization (ESI) both modes...
Abstract Peatlands in the northern hemisphere are a major carbon storage but face an increased risk of wildfires due to climate change leading large-scale smoldering fires boreal and Arctic peatlands. Smoldering release organic rich particulate matter, which influences earth’s radiative balance can cause adverse health effects for humans. Here we characterize molecular composition biomass burning matter generated by laboratory experiments peat electrospray ionization 21 T Fourier-transform...
Soot particles (SP) are ubiquitous components of atmospheric particulate matter and have been shown to cause various adverse health effects. In the atmosphere, freshly emitted SP can be coated by condensed low-volatility secondary organic inorganic species. addition, gas-phase oxidants may react with surface SP. Due chemical physical resemblance carbon backbone polyaromatic hydrocarbon species their potent oxidation products, we investigated biological responses BEAS-2B lung epithelial cells...
