Table 1.

Number and frequency of left‐censored data and quantifications in fish meat (FoodEx2 level 3), by chemical substance

Chemical Analytical results (n) Left‐censored (n) (a) Quantified (n) Left‐censored (%) Quantified (%)
Chlorates 200 127 73 63.5 36.5
SUM BAC 422 397 25 94.1 5.9
SUM DDAC 416 392 24 94.2 5.8
(a)

The number of left‐censored data refers to both the results below the LOQ and those below the LOD. For those analytical results that were reported below the LOD, the LB, MB and UB were assigned as LB = 0, MB = LOD/2 and UB = LOD. For the ones below the LOQ, the same approach was taken, using the value of the LOQ (LB = 0, MB LOQ/2, UB = LOQ).
