Study design

Inoculum or test system:
activated sludge (adaptation not specified)
Details on inoculum:
Activated sludge (2 L in a 4 L container) was collected the sameday the experiment was initiated from waste water treatmentplants (WWTPs) in the states of Pennsylvania, Maryland, and Delaware. The sludge was aerated at room temperature to suspend themicroorganisms and used as the inoculums or was autoclaved assterile controls. 129-mL glass serum sample bottles were used astest vessels. In each test vessel, 3 mL of activated sludge suspension was mixed with 27 mL of mineral media. The 10-fold dilution of the activated sludge was aimed to minimize potential absorption of 6:2 FTS and potential transformation products by activated sludge.
Duration of test (contact time):
90 d
