The fate of anthracene, a representative polycyclic
aromatic hydrocarbon, was followed in a large outdoor stream microcosm.
The major nonadvective route for the removal of anthracene was
phototolytic degradation to anthraquinone (half-life 43 min).
The anthraquinone also photolyzed rapidly in this shallow stream system.
Excluding the plastic channel liner, the sediment acts as the major sink
for anthracene, absorbing 0.2% of the 14-day input dose.
The periphyton community was the second most important sink, absorbing
0.045% of the input dose. All other
compartments were of significantly less importance on a mass basis.
Anthracene (11 µg liter-1) caused photo-induced 100%
mortality of the bluegill sunfish in 9 hr in the upstream reach.
Fish at the downstream station survived for ~ 26 hr and all died within 1
hr of each other. Other organisms,
clams and dragonfly larvae, started to die off toward the end of the 14 day
