Although hints of the variance oscillation remain in the 84-sample outflow plots, they satisfied the SM.
The stimulus-evoked overflow was estimated by subtracting transmitter content of the two 3-min samples (basal outflow) from release evoked in the 6-min sample collected during and after the depolarization pulse (stimulus-evoked release) [13].
These substances were detected in 80% of all surface water samples and in six out of seven sewage treatment plant outflow samples in Canada.
Dissolved methane concentrations from collected outflow samples and the possible surrogates ORP and DO, when measured at the same time that outflow samples were collected, appeared to be negatively correlated.
Sediment cores were plumbed as flow-through chemostats and inflow and outflow samples were analyzed for N2 gas to determine net denitrification rates.
Biofilter columns with differing soil media and vegetation types were dosed over a two month span, during which inflow and outflow samples were collected to evaluate system performance.
For further methane analysis, outflow samples at near steady state were carefully collected and completely filled in 20-mL serum bottles, so as not to create bubbles.
Collected outflow samples from the TDS surrogate tests were transferred in a cooler to the USEPA approved laboratory, and TDS were measured using USEPA method 160.1 USEPA 19799).
A water sample of the outflowing water was collected every 20 min in a clean test tube which was initially washed with distilled water.
The transformation rates were low with mean SDZ mass fractions in the outflow samples of 95% for the loamy sand compared to 97% for the silty loam.
For the silty loam we additionally measured a BTC for an unknown transformation product which we only detected in the outflow samples of this soil.
