GROSS NECROPSY
Maternal liver weight and gravid uterine weight were measured and corpora lutea were counted. Uterine contents were evaluated for the number of implantation sites, resorptions, late fetal deaths (i.e. fetuses with discernible digits and weighing greater than 0.9 g, but displaying no vital signs at the time of uterine dissection), and live fetuses. The uterus was stained to reveal possible early resorptions - Postmortem examinations (offspring):
- No data available
- Statistics:
- The unit for statistical measurement was the pregnant female or the litter. Quantitative continuous data were compared among treatment groups by parametric tests if Bartlett’s test for homogeneity of variance was not significant. If Bartlett’s test indicated a lack of homogeneity (p , 0.001), then nonparametric tests were applied. Statistical analyses were based on SAS software. General Linear Models (GLM) were applied to the Analyses of Variance (ANOVA) and the Tests for Linear Trend. Prior to GLM analysis, an arcsine-square root transformation was performed on all litter-derived percentage data.
For litter-derived percentage data, the ANOVA was weighted according to litter size. If a significant (p , 0.05) main effect for dose occurred, then Dunnett’s Multiple Comparison Test was used to compare each treatment group to the control group for that measure.
A two-tailed Dunnett’s Test was used for maternal body and organ weight parameters, maternal feed and water consumption, fetal body weight, and percent male fetuses per litter. - Reproductive indices:

- Conclusions:

- Executive summary:
1,2,3,4-butanetetracarboxylic acid (BTCA) was tested for reproductive toxicity.The experimental animals were Sprague Dawley of 8 to 10 weeks old. After quarantine, individual females were placed overnight in the home cage of a singly housed male of the same stock for mating, and then examined the next morning for the presence of sperm in thevaginal lavage. Female rats weighed from 218 to 269 gon gd 0 (i.e. day of vaginal sperm detection). Time-matedfemales were assigned to treatment groups (25/group) bystratified randomization for body weight on gd 0.
The BTCA doses chosen for this study were 0, 250, 500, and 1000 mg/kg/day administered by gavage (5 ml/kg). Dose range selection for this study was based in part on an acute, oral toxicity study of BTCA [800, 1260, 1590, 2000, and 3170 mg/kg] in COX-SD rats. Dose range selection was also supported by a study in non-pregnant female CD rats (7 per group) exposed to BTCA [0, 50,100,500,750, and 1000 mg/kg/day] for 14 consecutive days.
Following termination by CO2asphyxiation on gd 20, maternal liver weight and gravid uterine weight were measured and corpora lutea were counted. Uterine contents were evaluated for the number of implantation sites, resorptions, late fetal deaths (i.e. fetuses with discernible digits and weighing greater than 0.9 g, but displaying no vital signs at the time of uterine dissection), and live fetuses. The uterus was stained to reveal possible early resorptions.
Maternal feed and water consumption, body weight, and clinical signs were monitored throughout gestation. At termination (gd 20), confirmed-pregnant females (21 to 25 per group) were evaluated for clinical status and gestational outcome; live fetuses were examined for external, visceral, and skeletal malformations. There were no treatment-related effects on fetal growth, survival, or morphologic development. Therefore NOAEL considered to be 500 mg/kg/day, for the reproductive toxicity study of1, 2,3,4-butanetetracarboxylic acid (BTCA) was performed on CD rats.
Reference
Body weight and food consumption:Maternal body weight was comparable among groups on gd 0 and 6 (i.e. prior to the initiation of dosing). On gd 9, 12, 15, 18, and 19, maternal body weights at the low and mid doses were not affected (98.8 to 100.8% of concurrent controls), but maternal body weight at the high dose was significantly lower than the vehicle control on each of these days, except gd 9. On gd 20, maternal body weight at the high dose was significantly below the vehicle control. Decreases in maternal body weight became larger with repeated dosing, and the maximum reductions occurred at the end of the dosing period (gd 18, 19, and 20
Test substance intake:Maternal relative feed intake was transiently reduced at 1000 mg/kg/day from gd 6 to 9 and at 500 mg/kg/day from gd 12 to 15, although no changes were noted for the treatment period as a whole. Maternal relative water intake was increased at 1000 mg/kg/day for gd 12 to 15, 18 to 19, 19 to 20, and the treatment period as a whole.
Reproductive function: estrous cycle:No data available
Reproductive function: sperm measures:No data available
Reproductive performance:Treatment-related maternal mortality occurred in 4% (1/24) of high-dose females. All remaining females survived until scheduled necropsy on gd 20; pregnancy was confirmed in 84 to 100% per group
Organ weights:Gravid uterine weight and maternal relative liver weight were not affected. Absolute maternal liver weight exhibited a decreasing trend but showed no significant differences between control and BTCA-treated groups
Gross pathology:No data available
Histopathology:No data available
other findings:No data available
Body weight and food consumption:Average fetal body weight per litter in BTCA-treated groups was comparable to controls (97 to 103% of the average control weight for males, females or both sexes combined), and no significant dose-related trends were found.
Test substance intake:No data available
Reproductive function: estrous cycle:No data available
Reproductive function: sperm measures:No data available
Reproductive performance:No data available
Organ weights:No data available
Gross pathology:External malformations were limited to one control fetus with a short tail. Visceral malformations included hydronephrosis and/or hydroureter (3, 0, 5, and 1 fetuses in the control through high-dose groups). Each of these visceral findings has a recognizable background incidence in this species/strain and the incidence in this study failed to show a dose-related pattern. Skeletal malformations
(fused ribs or centra and split centra) were found in only one fetus in the control group and two fetuses in the Low - dose group. Thus, no association was found between BTCA exposure and the incidence of malformations

Reproductive toxicity study
Data available from different studies were reviewed to determine the reproductive toxicity of the test substance.The studies are as mentioned below:
Study 1
1,2,3,4-butanetetracarboxylic acid (BTCA) was tested for reproductive toxicity.The experimental animals were Sprague Dawley of 8 to 10 weeks old. After quarantine, individual females were placed overnight in the home cage of a singly housed male of the same stock for mating, and then examined the next morning for the presence of sperm in thevaginal lavage. Female rats weighed from 218 to 269 gon gd 0 (i.e. day of vaginal sperm detection). Time-matedfemales were assigned to treatment groups (25/group) bystratified randomization for body weight on gd 0.
The BTCA doses chosen for this study were 0, 250, 500, and 1000 mg/kg/day administered by gavage (5 ml/kg). Dose range selection for this study was based in part on an acute, oral toxicity study of BTCA [800, 1260, 1590, 2000, and 3170 mg/kg] in COX-SD rats. Dose range selection was also supported by a study in non-pregnant female CD rats (7 per group) exposed to BTCA [0, 50,100,500,750, and 1000 mg/kg/day] for 14 consecutive days.
Following termination by CO2asphyxiation on gd 20, maternal liver weight and gravid uterine weight were measured and corpora lutea were counted. Uterine contents were evaluated for the number of implantation sites, resorptions, late fetal deaths (i.e. fetuses with discernible digits and weighing greater than 0.9 g, but displaying no vital signs at the time of uterine dissection), and live fetuses. The uterus was stained to reveal possible early resorptions.
Maternal feed and water consumption, body weight, and clinical signs were monitored throughout gestation. At termination (gd 20), confirmed-pregnant females (21 to 25 per group) were evaluated for clinical status and gestational outcome; live fetuses were examined for external, visceral, and skeletal malformations. There were no treatment-related effects on fetal growth, survival, or morphologic development. Therefore NOAEL considered to be 500 mg/kg/day, for the reproductive toxicity study of1, 2,3,4-butanetetracarboxylic acid (BTCA) was performed on CD rats.
Study 2
Reproductive and development toxicity study of test chemical was performed on Dutch-belted female rabbits .The test material dissolved in water were administered in dose concentration 0.00,4.25, 19.75, 91.9 ,425.0mg/kg bw/day from day 6 through day 19 post-coitum by oral gavage route. Positive control 6-arninonicotinamide given in dose concentration 2.5mg/kg bw/day to 15 female rabbits and total 83 female rabbits were used in study.On Day 0 each dose was given an injection of 0.4 ml of human chorionic gonadotropin (400 IU) via the marginal ear vein. Three hours later, each doe was inseminated artificially with 0.3 ml of diluted semen from a proven donor buck using approximately 20 x 106 motile sperm according to the procedure described by vogin et al (Pharmacologist 11, 282 (1969)). Body weights were recorded on Days 0, 6, 12, 18, and 29 of gestation. All animals were observed daily for appearance and behaviour with particular attention to food consumption and weight,On Day 29 all dams were subjected to Caesarean section under surgical anesthesia, and the numbers of implantation sites, resorption sites, and live and dead fetuses were recorded. The body weights of the live pups were also recorded. The urogenital tract of each dam was examined in detail for anatomical normality. All fetuses underwent a detailed gross examination for the presence of external congenital abnormalities. The live foetuses of each litter were then placed in an incubator for 24 hours for the evaluation of neonatal survival. All surviving pups were sacrificed, and all pups examined for visceral abnormalities (by dissection) . All fetuses were then cleared in potassium hydroxide (KOH) , stained with alizarin red 5 dye and examined for skeletal defects.
No treatment-related clinical signs and premature deaths were observed.There were no treatment-related effects on female Body weight.No relevant necropsy findings were noted. The litter parameters like number of corpora lutea, implantation sites, early and late resorptions, dead and live foetuses were not affected by treatment with the test item. Also in foetal there were no treatment-related malformations or variations in any groups at external, soft tissue or skeletal examinations. Hence No Observed Adverse Effect Level (NOAEL) for reproductive and developmental toxicity was considered to be 425.0mg/kg bw,when Dutch-belted female rabbits were treated with test chemical orally.
Hence the test chemical is not likely to classify as a reproductive toxicant as per the criteria mentioned in CLP regulation.
Justification for classification or non-classification
Thus, comparing this value with the criteria of CLP regulation the test substance is not likely to classify as reproductive toxicant.
