L18 ANSWER 1 OF 647 CA COPYRIGHT 1999 ACS
TI Mineralization of Sparsely Water-Soluble ***Polycyclic***
***Aromatic*** ***Hydrocarbons*** in a Water Table Fluctuation
Zone
LA ***English***

The mineralization potential of sparsely water-sol. polycyclic arom.
hydrocarbons (PAHs) within a highly diesel-contaminated water table
fluctuation zone (WTFZ) was investigated using core-scale column
microcosms. Exptl. conditions mimicked overall seasonal changes in
water and oxygen content at the site. During the first aerobic
winter, ***PAH*** mineralization rates in the freshly
contaminated ***soil*** were fastest for contaminant
[14C]naphthalene, which was the least hydrophobic and most
water-sol. Lowering the water table nearly doubled the
mineralization rates of all [14C]PAHs studied. During the
oxygen-poor summer, all mineralization rates were insignificant and
failed to respond to water table changes. Neither a return to
water-satd. aerobic (winter) conditions nor lowering the water table
under aerobic conditions induced detectable mineralization of
[14C]naphthalene, but lowering the water table did markedly hasten
the still slow mineralization of [14C]phenanthrene and
[14C]anthracene. The time-dependent mineralization behavior and its
response to water table fluctuations were explicable in terms of
microbial responses to the changing oxygen content and depleting
mineral nutrients.
