Table 3 Minimal risk levels (MRLs) and maximum edible amounts (g/day) of fish muscle tissue, which a 70 kg person can consume per day without health risks (Q-values), determined for mean concentrations and concentration ranges (min–max, between brackets) in perch and eel across Flanders

From: PFAS accumulation in indigenous and translocated aquatic organisms from Belgium, with translation to human and ecological health risk
