Determination of urban volatile organic compound emission ratios and comparison with an emissions database [PDF]

, 2007
During the NEAQS-ITCT2k4 campaign in New England, anthropogenic VOCs and CO were measured downwind from New York City and Boston. The emission ratios of VOCs relative to CO and acetylene were calculated using a method in which the ratio of a VOC with ...

Seasonal measurements of total OH reactivity fluxes, total ozone loss rates and missing emissions from Norway spruce in 2011 [Discussion paper] [PDF]

, 2012
Numerous reactive volatile organic compounds (VOCs) are emitted into the atmosphere by vegetation. Most biogenic VOCs are highly reactive towards the atmosphere's most important oxidant, the hydroxyl (OH) radical.

Effects of Different Drying Methods on the Volatile Substances of Dictyophora rubrovolvata Based on HS-SPME-GC-MS and HS-GC-IMS

Shipin gongye ke-ji
To investigate the impact of different drying methods on the volatile organic compounds (VOCs) of Dictyophora rubrovolvata, HS-SPME-GC-MS and HS-GC-IMS technologies were employed to analyze the aroma changes of the mushroom dried by four methods, which ...

Associations of volatile organic compounds/semi-volatile organic compounds exposure on asthma: A review of epidemiological studies and diagnostic applications

环境与职业医学
Volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs) are common organic compounds in indoor and outdoor air, and enter the human body primarily through the respiratory tract and directly damage the respiratory system.

Initial study of three different pathogenic microorganisms by gas chromatography-mass spectrometry [version 3; referees: 2 approved, 1 approved with reservations]

F1000Research, 2018
Background: Diagnoses  of  respiratory  tract  infections  usually happen  in  the  late  phase  of  the  disease  and  usually  result  in  reduction  of  the  pathogen  load after broad-spectrum  antibiotic  therapy,  but  not  in eradication of the ...
