      abstract     = {The sorption of organic contaminants in soil is mainly
                      attributed to the soil organic matter (SOM) content.
                      However, recent studies have highlighted the fact that it is
                      not the total carbon content of the organic matter, but its
                      chemical structure which have a profound effect on the
                      sorption of organic contaminants. In the present study
                      sorption of two nitroaromatic contaminants viz.
                      trinitrotoluene (TNT) and 2,4-dinitrotoluene (2,4-DNT) was
                      studied in different SOM fractions viz. a commercial humic
                      acid, commercial lignin and humic acid and humin extracted
                      from a compost. (13)C-DP/MAS NMR studies indicated that the
                      structural composition of the organic carbon in different
                      SOM fractions was different. The order of sorption of the
                      nitroaromatics in the different sorbents was: humic
                      acid-commercial>humic acid-compost>humin approximately
                      lignin. Among the aliphatic and aromatic carbon fractions
                      (representing bulk of SOM matrix), adsorption parameter
                      K(f)(1/n) for nitroaromatics sorption correlated well with
                      the aliphatic carbon (r=0.791 for TNT and 0.829 for 2,4-DNT)
                      than the aromatic carbon (r=0.634 for TNT and r=0.616 for
                      2,4-DNT). However, among carbon containing functional
                      groups, carbonyl carbon showed strong positive correlation
                      with sorption of TNT (r=0.991) and 2,4-DNT (r=0.967) while
                      O-alkyl carbon showed negative correlation (r=0.832 for TNT
                      and r=0.828 for 2,4-DNT). The study indicates that aliphatic
                      domains in the SOM significantly affect the non-specific
                      sorption of both the nitroaromatic contaminants.},
