--
Short term toxicity. Target / critical effect: No specific
target organ toxicity (rat, dog) Reduced
bodyweight and food consumption/ utilisation efficiency
at highest dose tested. Lowest relevant oral NOAEL / NOEL: 90-d
& 1-yr dietary, dog: 4.3 mg/kg bw/d. Lowest relevant dermal NOAEL
/ NOEL: 28-d, rat: >1000 mg/kg bw/d (limit dose)
-- Reproductive toxicity. Target / critical
effect - Reproduction: No effects on reproductive performance;
reduced body weights of offspring
at the end of the lactation period at parentally toxic doses (750
ppm). Lowest relevant reproductive NOAEL / NOEL: 2-gen, rat: >750
ppm (78.2 mg/kg bw/d), this being the highest dose tested; 200
ppm (parent rats) Target / critical effect
- Developmental toxicity: Ossification
delay and increased incidence of skeletal variants at maternally
toxic doses.
Lowest relevant developmental NOAEL / NOEL: rat: 30 mg/kg bw/day
rabbit: 25 mg/kg bw/day
-- Long term toxicity and carcinogenicity.
Target / critical effect: No significant target organ toxicity.
Reduced bodyweight and food consumption
at the highest dose tested (750 ppm). Lowest relevant NOAEL: 2-yr,
rat: 200 ppm (12.2 mg/kg bw/d). Carcinogenicity: No evidence of
carcinogenicity
-- Other
toxicological studies. o-phthalic
acid (Metabolite 15, grain): Survey of published literature
(November 2000) Acute oral LD50, rat: 7500-8400 mg/kg bw In-vitro
genotoxicity (Ames test & cytogenetic assay in CHO cells): negative.
Dominant lethal test: questionable positive test result involving
reduced male fertility and abnormal sperm morphology. Non-carcinogenic
in rats and mice according to NTP carcinogenicity programme. Reduced
foetal body weight and retarded ossification
in rats at maternal toxic doses
