Overview
The EFSA CONTAM Panel maintained the tolerable weekly intake for inorganic mercury at 4 µg Hg/kg body weight per week in its December 2012 Scientific Opinion on Mercury and Methylmercury in Food, aligned with the prior JECFA value (EFSA Hg 2012). The TWI is anchored on renal effects observed in chronic inorganic mercury exposure studies (EFSA Hg 2012).
| Parameter | Value |

| TWI | 4 µg Hg/kg b.w./week (expressed as Hg) |
| Critical endpoint | Renal effects |
| Adopting body | EFSA CONTAM Panel; aligned with JECFA |
| Confirmed | December 2012 |
