abstract = {After 22 years of aging under natural conditions in an
outdoor lysimeter the bioaccessibility of C-14-labeled
atrazine soil residues to bacteria was tested. Entire soil
samples as well as sand-sized, silt-sized, and clay-sized
aggregates (> 20, 20-2, and < 2 mu m aggregate size,
respectively) were investigated under slurried conditions.
The mineralization of residual radioactivity in the outdoor
lysimeter soil reached up to $4.5\%$ of the total
C-14-activity after 16 days, inoculated with Pseudomonas sp.
strain ADP. The control samples without inoculated bacteria
showed a mineralization maximum of only about $1\%$ after 44
days of incubation. Mineralization increased in the
clay-sized aggregates up to $6.2\%$ of the total residual
14C-activity within 23 days. With decreasing soil aggregate
sizes, residual C-14-activity increased per unit of weight,
but only minor differences of the mineralization in the soil
and soil size aggregates using mineral-media for incubation
was observed. Using additional Na-citrate in the
incubation,the extent of mineralization increased to $6.7\%$
in soil after 23 days following incubation with Pseudomonas
sp. strain ADP. These results show that long-term aged
IT-atrazine residues are still partly accessible to the
atrazine degrading microorganism Pseudomonas sp. strain
ADP.},
