Analyses included water-soluble ions, metals, radionuclides, organic and elemental carbon (OC and EC), humic-like substances (HULIS), cellulose and approximately l80 organic compounds. Particle (PM10) emission factors from eucalyptus and oak were higher than those from pine and acacia. The carbonaceous matter represented 44e63% of the particulate mass emitted during the combustion process, regardless of species burned. The major organic components of smoke particles, for all the wood species studied, with the exception of the golden wattle (0.07e1.9% w/w), were anhydrosugars (0.2e17% w/w). Conﬂicting with what was expected, only small amounts of cellulose were found in wood smoke. As for HULIS, average particle mass concentrations ranged from 1.5% to 3.0%. The golden wattle wood smoke presented much higher concentrations of ions and metal species than the emissions from the other wood types. The results of the analysis of radionuclides revealed that the 226 Ra was the naturally occurring radionuclide more enriched in PM10. The chromatographically resolved organics included n-alkanes, nalkenes, PAH, oxygenated PAH, n-alkanals, ketones, n-alkanols, terpenoids, triterpenoids, phenolic compounds, phytosterols, alcohols, n-alkanoic acids, n-di-acids, unsaturated acids and alkyl ester acids.</style></abstract><issue><style face="normal" font="default" size="100%">35</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;publisher: Elsevier Ltd</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Delafuente, E.</style></author><author><style face="normal" font="default" size="100%">Sanz, M.</style></author><author><style face="normal" font="default" size="100%">Martinezcastro, I.</style></author><author><style face="normal" font="default" size="100%">Sanz, J.</style></author><author><style face="normal" font="default" size="100%">Ruizmatute, A.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Volatile and carbohydrate composition of rare unifloral honeys from Spain</style></title><secondary-title><style face="normal" font="default" size="100%">Food Chemistry</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">carbohydrates</style></keyword><keyword><style  face="normal" font="default" size="100%">gc</style></keyword><keyword><style  face="normal" font="default" size="100%">GC-MS</style></keyword><keyword><style  face="normal" font="default" size="100%">honey</style></keyword><keyword><style  face="normal" font="default" size="100%">ms</style></keyword><keyword><style  face="normal" font="default" size="100%">polyalcohols</style></keyword><keyword><style  face="normal" font="default" size="100%">volatile compounds</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2007</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2007///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://linkinghub.elsevier.com/retrieve/pii/S0308814607002920</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">105</style></volume><pages><style face="normal" font="default" size="100%">84 - 93</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Volatile composition and carbohydrate content of Spanish honey samples from uncommon botanical origins have been studied by gas chromatography coupled to mass spectrometry. About 100 volatile compounds were identiﬁed; some of them appeared to be characteristic of particular honey types, such as methyl salycilate in willow (Salix spp.), 2,6,6-trimethyl-2,4-cycloheptadien-1-one (eucarvone) in almond tree (Prunus dulcis) and isophorone in strawberry-tree (Arbutus unedo). Concentration ranges for major carbohydrates were similar to those previously reported in other honeys with diﬀerent botanical origins, although concentrations of maltulose in avocado honeys (Persea americana) and of melezitose in Quercus ilex honeys were higher. Some carbohydrate alcohols could also be considered as markers of honey botanical origin, such as quercitol for Q. ilex and perseitol for avocado.</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Garcia-Martin, G.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Effect of exogenous ABA on embryo maturation and quantification of endogenous levels of ABA and IAA in Quercus suber somatic embryos</style></title><secondary-title><style face="normal" font="default" size="100%">Plant cell, tissue and …</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Cork oak</style></keyword><keyword><style  face="normal" font="default" size="100%">endogenous plant growth regulators</style></keyword><keyword><style  face="normal" font="default" size="100%">GC-MS</style></keyword><keyword><style  face="normal" font="default" size="100%">hplc</style></keyword><keyword><style  face="normal" font="default" size="100%">in vitro</style></keyword><keyword><style  face="normal" font="default" size="100%">somatic embryo</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2005</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2005///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.springerlink.com/index/U76R638228070M15.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">80</style></volume><pages><style face="normal" font="default" size="100%">171 - 177</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Knowledge of the relationship between indole-3-acetic acid (IAA) and abscisic acid (ABA) is relevant to control the development and the maturation of cork oak (Quercus suber L.) somatic embryos. The addition of 1 lM ABA to the culture medium signiﬁcantly promoted somatic embryo maturation and increased both fresh and dry matter without aﬀecting the relative water content. This eﬀect was parallel to the pattern of variation observed in the endogenous ABA level, which increased from the immature to the mature stage. Endogenous ABA content during the occurrence of secondary embryogenesis was similar to that of the immature stage, showing that embryos with lower ABA levels produced secondary embryos. In contrast, IAA showed the highest concentration during early embryo development and decreased afterwards. Only in somatic embryos subjected to 1-week desiccation followed by stratiﬁcation at 4 C for 2 weeks, was a moderate increment of endogenous IAA content observed. IAA and ABA showed opposite levels during the development and maturation of cork oak somatic embryos and characterised speciﬁc stages of the embryonic development.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Cabañas, Aracel</style></author><author><style face="normal" font="default" size="100%">Sáez, Felicia</style></author><author><style face="normal" font="default" size="100%">González, Alberto</style></author><author><style face="normal" font="default" size="100%">Escalada, Ricardo</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Quantitative Assessment of Polycyclic Aromatic Hydrocarbons from Corkwaste Combustion Emissions</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of Agricultural Engineering Research</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Cork waste</style></keyword><keyword><style  face="normal" font="default" size="100%">Fluidized bed combustion (PG)</style></keyword><keyword><style  face="normal" font="default" size="100%">GC-MS</style></keyword><keyword><style  face="normal" font="default" size="100%">Polycyclic aromatic hydrocarbons (PAHs)</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2000</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2000///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://linkinghub.elsevier.com/retrieve/pii/S0021863400905948</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">77</style></volume><pages><style face="normal" font="default" size="100%">349 - 354</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Cork is a natural raw material obtained from the cork oak (Quercus suber). The corkwaste is a potential source of polycyclic aromatic hydrocarbons (PAHs) due to its high content of volatile compounds. A sampling method was developed for the measurement of polycyclic aromatic hydrocarbons emissions in a pilot bubbling #uidized bed combustion. This method has been designed to assess simultaneously the PAH contained in the gas phase and in the particulate matter. The samples were analysed on a gas chromatography coupled to a mass spectrometer to identify and quantify PAH compounds. The mass-selective detector was run in the selected ion monitoring mode. This study shows that lower molecular weight PAH were present predominantly in the gas phase, whereas high weight PAHs were retained in the particulate phase. As there is an existing relationship between the emission of CO and polycyclic aromatic hydrocarbons, the control and assessment of both compounds have been performed.</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">ALMENDROS, G.</style></author><author><style face="normal" font="default" size="100%">Sanz, J.</style></author><author><style face="normal" font="default" size="100%">VELASCO, F.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Signatures of lipid assemblages in soils under continental Mediterranean forests</style></title><secondary-title><style face="normal" font="default" size="100%">European Journal of Soil Science</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">GC-MS</style></keyword><keyword><style  face="normal" font="default" size="100%">Lipids</style></keyword><keyword><style  face="normal" font="default" size="100%">Lipids assemblage (voyant)</style></keyword><keyword><style  face="normal" font="default" size="100%">mediterranean forest soils</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1996</style></year><pub-dates><date><style  face="normal" font="default" size="100%">1996///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://dx.doi.org/10.1111/j.1365-2389.1996.tb01389.x</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">47</style></volume><pages><style face="normal" font="default" size="100%">183 - 196</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The analysis of free lipids in 12 soils from three representative types of Mediterranean forest has been carried out in an attempt to describe diagnostic molecules reflecting differences between the ecosystems and the intensity of the soil organic matter turnover. The study centred on the analysis by gas chromatography–mass spectrometry of the soil compounds extracted with petroleum ether from soils in central Spain, developed under monospecific formations of stone pine (Pinus pined), evergreen oak (Quercus rotundifolia) and Spanish juniper (Juniperus thurifera), the lipid extracts from their leaves also being analysed as reference material. The comparison between the distribution patterns of alkanes and fatty acids in plant lipids and the corresponding soil lipids was used to assess the extent to which the former accumulate in soil or are substituted by other biogenic or diagenetic homologues. In general, the alkane patterns showed the greatest variation in soils under oak, and the differences between lipid patterns in plant and soil were greatest in the juniper forests. As indicators of the vegetation type, the soil fatty acids had little value. Up to 60 major cyclic compounds were identified, including mainly di- and sesquiterpenes, in addition to some monoterpenes and nonterpenic naphthalenes and decalins. Of these major constituents, 33 compounds were found in soil but were not present in plant extracts, and 18 compounds were identified in plants but were not in the soils. The results suggest an arrangement of the soil samples based on the composition of the signature lipid assemblages.</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;publisher: Blackwell Publishing Ltd</style></notes></record></records></xml>
