Name: 3,7-Dimethyloctan-3-ol《Biogenic volatile organic compound (BVOC) emissions from forested areas in Turkey: Determination of specific emission rates for thirty-one tree species》 was published in 2014. The authors were Aydin, Yagmur Meltem;Yaman, Baris;Koca, Husnu;Dasdemir, Okan;Kara, Melik;Altiok, Hasan;Dumanoglu, Yetkin;Bayram, Abdurrahman;Tolunay, Doganay;Odabasi, Mustafa;Elbir, Tolga, and the article was included in《Science of the Total Environment》. The author mentioned the following in the article:
Normalized biogenic volatile organic compound (BVOC) emission rates for 31 tree species which cover 98% of national forested areas in Turkey were determined Field sampling was performed at 14 forested areas using a specific dynamic enclosure system. Selected branches of tree species were enclosed in a chamber consisting of a transparent Nalofan bag. Air flow was sampled from chamber inlet and outlet by Tenax-filled sorbent tubes during tree photosynthesis in the presence of sunlight. Several environmental parameters (temperature, humidity, photosynthetically-active radiation [PAR], CO2) were continuously monitored inside and outside the enclosure chamber during sampling. Collected samples were analyzed by gas chromatog./mass spectrometry with thermal desorption. In total, 65 BVOC classified in 5 major groups (isoprene, monoterpenes, sesquiterpenes, oxygenated sesquiterpenes, other oxygenated compounds) were analyzed. Emission rates were determined by normalization to standard conditions (1000 μmol/m2-s PAR and 30° for isoprene, 30°C for the remaining compounds). In agreement with the literature, isoprene was mostly emitted by broad-leaved trees while coniferous species mainly emitted monoterpenes. Several tree species (sweet chestnut, silver lime, European alder) had higher monoterpene emissions, although they are broad-leaved species. High isoprene emissions were also observed for several coniferous species (Nordmann fir, Oriental spruce). The highest normalized total BVOC emission rate, 27.1 μg/g-hm was observed for Oriental plane while southern European flowering ash was the weakest BVOC emitter with a total normalized emission rate of 0.031 μg/g-h. Monoterpene emissions from broad-leaved species mainly consisted of sabinene, limonene, and trans-β-ocimene; α- and β-pinene and β-myrcene were generally emitted by coniferous species. Oxygenated compounds were the third most prominent BVOC group; sesquiterpenes had slightly lower contributions. And 3,7-Dimethyloctan-3-ol (cas: 78-69-3) was used in the research process.
3,7-Dimethyloctan-3-ol(cas:78-69-3) is a fatty alcohol that is 3-octanol substituted by methyl groups at positions 3 and 7.Name: 3,7-Dimethyloctan-3-ol Metabolite observed in cancer metabolism. It has a role as a human metabolite.
