Children who had received emergency treatment for asthma were found to have been exposed to significantly higher concentrations of volatile organic compounds (VOCs) at homeBMJOccupational & Environmental Medicine
Volatile organic compounds such as benzene are toxic pollutants that cause health issues even at trace concentrations. Here, a double-walled metal–organic framework is presented that demonstrates high uptake at very low pressures (<10 Pa), allowing the removal of benzene to below acceptable indoo...
It is generally accepted that the formation of kerogens is the result of the so-called depolymerization-recondensation pathway (Tissot and Welte, 1984; Durand, 1980), Thus, naturally occurring macromolecular substances such as polysaccharides and protein
The data used for this study are released on the Planetary Data System (PDS) athttps://pds.nasa.gov/. Data from the SHERLOC instrument are accessible athttps://pds-geosciences.wustl.edu/missions/mars2020/sherloc.htm. Spectral data are organized by sol number and accessible in csv format at...
to identify the phenolic compounds with antioxidant activity present in them. The highest content of phenolic compounds, calculated as gallic acid, was found inB. edulis(over 35.00 mg/g d.w.); while, the level of the phenolic substances in the other two species was lower (approximately 6.30...
Volatile organic compounds (VOCs) exert considerable influence on tropospheric chemistry; they play a key role in the formation and production of secondary air pollutants such as ozone, peroxyacetyl nitrates, aldehydes, and secondary organic aerosols through complex photochemical cycles (Seinfeld and Pandis...
REL is defined as the concentration at or below which no adverse non-cancer health effects are anticipated following long-term exposure (OEHHA, 2003). Table 3. Target HAPs and associated toxicity values. CompoundsWeight of evidenceCancer potency factor (mg/kg/day)− 1Cancer benchmark ...
would be the detection of water and solvent vapours in the gas phase with the possibility of differentiating between various substances. COFs featuring this kind of nosing capability could be a powerful tool for detecting harmful volatile organic compounds in workplace environments, or for real-time...
Kind Code: A1 Abstract: Treatment of exhaust air loaded with volatile organic compounds (VOC's) comprises washing the air with a processing liquid (24) in which they are at least partially soluble. An independent claim is included for apparatus for carrying out the treatment comprising a VOC ...
such as in separating chemical compounds by their boiling point by heating them to a temperature at which several fractions of the compound will evaporate. Absorption chromatography is a physical separation method in which the components of a mixture are separated by differences in their distribution ...
