Phytochemical study of the headspace volatile organic

2018年5月8日 · DMS, a highly-volatile organosulfur compound was quite abundant in the headspace of F. petiolata (22.2%; Table 1 ) and in general serves to the algae as a chemoattractant [ 25 , 26 ]. Since DMS distribution in the water column does not correlate well with phytoplankton biomass [ 39 ], it led to suggestions that only certain groups of marine algae

What are volatile organic compounds (VOCs)? - US EPA

2022年12月27日 · Volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors. VOCs are emitted by a wide array of products numbering
