Table 2.
Measured amitriptyline concentrations of the second experiment (limit of quantification (LoQ) 0.1 µg/L; for calculation of mean exposure concentrations values below the limit of quantification were substituted with LoQ/√2; MPtt: 104 particles/L PS MP; MPht: 105 particles/L PS MP; MIXtt: amitriptyline + 104 particles/L; MIXht: amitriptyline + 105 particles/L).
