Applicant's summary and conclusion

Interpretation of results:
Toxicity Category III
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
In an acute oral toxicity study (reliability score 2, not to GLP) in which a control group of mice were given ferric chloride the LD50 was 440 mg Fe/kg bw, equivalent to 1,300 mg ferric chloride/kg body weight.
Executive summary:

In an acute oral toxicity study (reliability score 2, not to GLP) in which a control group of mice (20 females) were given ferric chloride at doses of 186, 335, 604, 1087 mg Fe/kg bw (equivalent to 540, 974, 1,756, 3160 mg ferric chloride/kg bw) by oral gavage, and then observed for one month, the LD50 was 440 mg Fe/kg bw (equivalent to 1,300 mg ferric chloride/kg body weight). This value was based on 1/10, 2/10, 8/10 and 10/10 deaths in the 186, 335, 604, 1087 mg Fe/kg bw groups, respectively.
