A mixed-effects model identified statistically significant associations between PCE in exhaled breath and airborne PCE time weighted average (TWA) after adjusting for a random participant effect and fixed effects of time and body mass index.
The concentration of PCE in the blood specimens obtained on Thursday was significantly correlated with PCE TWA from Wednesday and PCE in the post-shift exhaled breath samples from Wednesday.
3 We were not able to access calibration of PCE in our study population, but recent data indicates that PCE is reasonable well calibrated (similar to SCORE) in a UK 'low-risk' population.
Other recommended BEIs are 0.5 mg/L (500 ng/ml) PCE in blood and 3.5 mg/L trichloracetic acid (TCA), the major PCE metabolite, in urine.
Decreases in PCE in exhaled breath and TCA in urine were observed after two days without exposure to PCE.
Dissolved PCE in the effluent reached a steady-state value of 27.0 mg L−1.
Apparent aqueous solubility of PCE in the presence of Tween-80 (M L−3).
The following factors require additional study for further enhancement of PCE in OSCs using carbon nanomaterials.
At present, the highest PCE in published papers is 22.6%, and the NREL chart records 22.7%.
The density increased somewhat with the solubilization of PCE in the surfactant solution.
