| Toxicological guidance value | At the 72rd meeting (2010), JECFA established a PTWI for inorganic mercury of 4 ug/kg bw. The previous PTWI of 5 ug/kg bw for total mercury, established at the sixteenth meeting, was withdrawn. The new PTWI for inorganic mercury was considered applicable to dietary exposure to total mercury from foods other than fish and shellfish. For dietary exposure to mercury from these foods the previously established PTWI for methyl mercury should be applied. |
