3.1 Results

3.1.1 Quality Assurance/Quality Control

Good method recoveries were obtained for phthalates, ranging from 80 to 131% in zooplankton samples and from 82 to 97% in water samples. OPE recovery rates ranged from 66 to 107%. Only a few PAEs were detected in the blanks and at low levels compared to real samples (<5% of DiBP and <13% of DEHP of real zooplankton sample concentrations).

DMP and DnBP were found with 1.5 (±0.05) ng L−1 in SPE blank replicates and DiBP with 3.1 (±0.13) ng L−1. For OPEs, 0.4 ng L−1 of TiBP, TnBP and TPhP, as well as 5.5 ng L−1 of TCPP-1 were measured in SPE blanks. All contaminant concentrations presented here are blank-corrected. Surrogates tracked extraction accuracy and internal standards ensured analysis accuracy. All SPE procedures were performed in a clean room (class ISO 6) equipped for organic studies at trace concentrations. Plastic materials were completely avoided during sampling, sample preparation and analysis. All glassware and filters were pre-combusted at 450 ℃ for 6 h.
