Evaluations


Evaluation year: 1982
Comments: The level of copper in food meets the nutritional requirements (2-3 mg/day for adults; 0.5-0.7 mg/day for infants). Copper is not carcinogenic in either humans or animals, and copper salts are not embryotoxic in rodents. Highly-exposed populations do not appear to be adversely affected, nor does copper appear to be a cumulative toxic hazard for man, except for individuals with Wilson's disease. On this basis, the previous tentative evaluation of a maximum daily load of 0.5 mg/kg bw was reaffirmed as a provisional value for a maximum tolerable intake of 0.5 mg/kg bw per day from all sources.
Tolerable Intake: PMTDI 0.5 mg/kg bw per day
