Incorporation of natural alcohols from plant residues into hydromorphic forest‐podzol

Abstract: The proportion of alcohols in soil lipids was studied in an hydromorphic forest-podzol. The L and F litter layers and the soil A l horizon were sampled and analysed for total lipid and total alcohol contents. Total alcohols were separated into four fractions: primary alkanols, secondary alkanols, sterols and triterpenic alcohols.From the L layer to the soil A I horizon, all the fractions decreased sharply, except frcc primary alkanols and sterols. The decomposition of secondary alkanols was virtually complctc.… Show more

“…However, given the age and former environmentally exposed position of the roof turf, one would expect the sample to have suered considerable degradation with no new input of lipid from vegetation. Under such a scenario the dominant C 52 component would exhibit considerable degradation (Jambu et al, 1993) whilst the gradual increase in abundance, with chain length, observed may well arise from an inverse relationship between rate of loss and chain length as previously reported for aliphatic compounds (AmbleÁ s et al, 1994).…”

“…Jambu et al (1993) reported an increase in free primary n-alkanols from L to F to A1 horizon in a soil pro®le beneath a cover of pine trees (Pinus maritima ssp.). The soil samples in this study dier in that they have, within any pro®le, been largely excised from the same horizon which originates as a consequence of anthropogenic and not natural processes.…”

“…Compounds 1,2,4,6-8,10 and 11 were identified by co-injection of pure standards. The structure of the other compounds were assigned on MS grounds and by comparison with literature data [14][15][16][17][18][19] . Figure 1.…”

“…Più recentemente Piccolo (2001;2002) ha dimostrato che le sostanze umiche sono in realtà associazioni supramolecolari di molecole eterogenee, di massa relativamente piccola e autoassociate in dimensioni molecolari solo apparentemente grandi, stabilizzate da legami deboli (van der Waals, π-π, legami a ponte di H), che possono essere scissi da minime quantità di acidi organici. Queste associazioni umiche interagiscono facilmente con i composti freschi di origine vegetale o microbica che vengono così progressivamente incorporati e stabilizzati nelle frazioni più recalcitranti della SO (Jambu et al, 1993;Lichtfouse et al, 1995;Almendros et al, 1996).…”
