Part 1 was a survey of levels of PFAS in sediments from 15 English estuaries collected in 2020. Additional funding was obtained to survey levels of PFAS in flatfish samples (flounder, dab and plaice) from the same estuaries and the output is a spreadsheet showing the concentrations of PFAS in these fish samples.

Samples were pools of 3 whole fish homogenised together. Samples were extracted and cleaned up for analysis of perfluoroalkyl substances (PFAS) in Cefas's Lowestoft chemistry laboratorys. Sample extracts were analysed by liquid chromatography-mass spectrometry (LC-MS) using internal standards and a 10 point calibration series. Results from the instrument were calculated back to concentrations in the fish tissue on a wet weight basis. For every 10 samples that were analysed, a blank and reference material sample were analysed to check that no contamination was introduced in the labs and that the method obtained the correct concentrations in the reference material. The lab also takes part in the Quasimeme international profficiency testing scheme twice a year and results from these demonstrate that the method generates results on a par with other labs.
