Subchronic and Reproductive/Developmental (Screening Level) Toxicity of Complexation Products of Iron Trichloride and Sodium Tartrate (FemTA)
Bibliographic record
Abstract
A complexation/reaction product, termed FemTA, of sodium tartrate [D(-)- and L(+)-tartaric acid and mesotartaric acid], sodium hydroxide, and iron trichloride may have use as an anticaking agent in salt preparations. FemTA is composed of about 4% sodium tartrate, approximately 10% mesotartaric acid, approximately 7% chloride, approximately 4% iron, approximately 7% sodium, approximately 0.3% sodium oxalate, and approximately 65% water. FemTA was tested in a 90-d oral toxicity study, which included a screening level reproductive/developmental toxicity phase, in Harlan Wistar rats. FemTA was administered by oral gavage at 500, 1000, and 2000 mg/kg body weight/d prior to and during mating, or about 20, 40, or 80 mg of iron/kg body weight/d, such that males received 90/91 d of treatment and females 104 to 109 d. Treatment was associated with inflammatory lesions of the lower GI tract at the mid- and high-dose levels, increased liver and kidney weights, increased serum bile acids and blood urea nitrogen, decreased chloride, and changes to hematological parameters consistent with inflammation. The effects were considered the result of iron overload. There were no effects on reproductive/developmental toxicity parameters. The no-observed-adverse-effect level (NOAEL), based on gastrointestinal tract effects was 500 mg/kg body weight/d. The NOAEL for reproductive/developmental toxicity was 2000 mg/kg body weight/d, the highest dose tested.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
