Description of key information
Repeated dose toxicity: Oral
The no-observed- adverse-effect-level (NOAEL) for male rats was considered to be 20 mg/kg/day and NOAEL for female rats was considered to be 100 mg/kg/day when Crl:CD (SD) male and female rat were treated with test substance.
Repeated dose toxicity: Inhalation
According to Annex IX of the REACH regulation, testing by the inhalation route is appropriate only if exposure of humans via inhalation is likely. Taking into account the low vapour pressure of the substance 3-Nitrobenzoic acid (121-92-6) which is reported as 0.0000371 mmHg at 25 C. Thus, exposure to inhalable dust, mist and vapour of the chemical 3-Nitrobenzoic acid (121-92-6) is highly unlikely. Therefore this study is considered for waiver.
Repeated dermal study;
The acute toxicity value for 3-Nitrobenzoic acid (121-92-6) (as provided in section 7.2.3) is >2000 mg/kg body weight. Also, given the use of the chemical; repeated exposure by the dermal route is unlikely since the use of gloves is common practice in industries. Thus, it is expected that 3-Nitrobenzoic acid shall not exhibit 28 day repeated dose toxicity by the dermal route. In addition, there is no data available that suggests that 3-Nitrobenzoic acid shall exhibit repeated dose toxicity by the dermal route. Hence this end point was considered for waiver.

Additional information
Various data available for the test chemical was reviewed to determine the toxic nature of m-nitrobenzoic acid (121-92-6) upon repeated exposure by oral route. The studies are as summarized below:
Repeated dose toxicity: Oral
In a combined repeated dose repro-devp. Screen, Crl:CD (SD) male and female rats were treated with test chemical in the concentration of 0, 20, 100, 500 mg/kg/day orally for 42 days in male rats and 55 days (from 14 days before mating to day 4 of lactation). The animal were fed the diet containing the test chemical daily and were observed for clinical signs, mortality, body weight and food consumtion changes, hematological and urine analysis, organ weight changes and histopathology. When treated with 500 mg/kg/day, Salivation was observed in male and female rats and decrease in locomotor activity, irregular respiration, prone position and drastic worsening was observed in female rat. 3 female rat died at 500 mg/Kg/day. When treated with 500 mg/kg/day, restrained body weight gain was noted in male rats. A decrease in food consumption was noted on day 8 in 500 mg/Kg/day male and female rats. At 500 mg/Kg/day, a decrease in red blood cell, hemoglobic and hematocrit values was noted in male and female rats. An increase in the A/G ration, Pi, K was noted in males and ALT increase was noted in females at 500 mg/Kg/day dose. However, a decrease in BUN, TP and CL was noted in male rats at 500 mg/Kg/day. No effects were noted for urianalysis in male and female rats at any of the dose levels. When treated with 500 mg/kg/day, in male rats, relative weight of Brain, Liver and Kidney increased, absolute and relative weight of Testes, Epididymides and absolute weight of Thymus decreased. During recovery, absolute and relative weigh of Testes and Epididymides were decreased in male rats. In female rats, when treated with 500 mg/kg/day, relative Liver and Spleen weight increased and absolute Thymus weight decreased. During recovery, absolute spleen and kidney weight increased. In male rats, Squamous hyperplasia, Erosion and Focal inflammatory cell infiltration in the forestomach, Small and soft testes, Small epididymides, Degeneration in seminiferous tubular epithelium in the testes, Decrease in sperm and Cell debris in the epididymides duct and increase in trabecular bone in the femur bone were observed in 500 mg/kg/day treated and in recovery period. When treated with 100 mg/kg/day, Squamous hyperplasia in the forestomach were observed in male rats. In female, Squamous hyperplasia, Erosion in the forestomach and an Increase in trabecular bone in the femur bone in 500 mg/kg/day treated and an Increase in trabecular bone in the femur bone in recovery period at 500 mg/Kg/day was noted. Based on the observations made, the no-observed- adverse-effect-level (NOAEL) for male rats was considered to be 20 mg/kg/day and NOAEL for female rats was considered to be 100 mg/kg/day when Crl:CD (SD) male and female rat were treated with test chemical.
In a Chronic repeated dose toxicity study, B6C3F1 male and female mice were treated test chemical in the concentrations of 0, 0.125, 0.25, 0.5, 1.0 and 2.0 % ( 0, 208, 417, 833, 1667 and 3333 mg/kg/day) orally. The animals were observed for mortality, changes in body weight and histopathology. No effect was observed on survival and the final body weight of mice at ≥ 833 mg/Kg/day were lower (P<0.05) than that of controls. In addition, no histopathological change was observed in male and female mice when treated up to a dose level of 3333 mg/Kg/day. Based on the observations made, the no-observed- effect-level (NOEL) was considered to be 0.25 % (417 mg/kg/day) when B6C3F1 male and female mice were treated with test chemical.
In the same study, toxic details for rats were also mentioned. In a Chronic repeated dose toxicity study, F344 male and female rats treated with test chemical in the concentrations of 0, 0.063, 0.125, 0.25, 0.5 and 1% (0, 31.2, 62.5, 125, 250 or 500 mg/Kg/day) orally for 13 weeks. The animals were observed for mortality, changes in body weight, hematology and clinical chemistry parameters and histopathology. No mortality was noted at any of the studied dose level. Final body weight of rats at 500 mg/Kg/day were lower (P<0.05) than that of controls. Male rats at all dose levels had significantly more Heinz bodies than controls. Methemoglobin concentration in female at 500 mg/Kg/day dose level was significantly increased. Females at 250 and 500 mg/Kg/day dose levels had lower hemocrit values, hemoglobin concentration and red blood cell count. Methemoglobin concentration was increased (p<0.05) in females at ≥ 125 mg/Kg/day dose levels. There was a significant decrease in total and free plasma levels of T-4 in males at 250 and 500 mg/Kg/day dose levels. Testicular atrophy was noted at 500 mg/Kg/day in male rats. Based on the observations made, the No Observed Adverse Effect Level (NOAEL) for male rats is considered to be 125 mg/Kg/day and for female rats the NOAEL is considered to be 62.5 mg/Kg/day when treated with test chemical for 13 weeks.
Repeated dose toxicity: Inhalation
According to Annex IX of the REACH regulation, testing by the inhalation route is appropriate only if exposure of humans via inhalation is likely. Taking into account the low vapour pressure of the substance 3-Nitrobenzoic acid (121-92-6) which is reported as 0.0000371 mmHg at 25 C. Thus, exposure to inhalable dust, mist and vapour of the chemical 3-Nitrobenzoic acid (121-92-6) is highly unlikely. Therefore this study is considered for waiver.
Repeated dermal study;
The acute toxicity value for 3-Nitrobenzoic acid (121-92-6) (as provided in section 7.2.3) is >2000 mg/kg body weight. Also, given the use of the chemical; repeated exposure by the dermal route is unlikely since the use of gloves is common practice in industries. Thus, it is expected that 3-Nitrobenzoic acid shall not exhibit 28 day repeated dose toxicity by the dermal route. In addition, there is no data available that suggests that 3-Nitrobenzoic acid shall exhibit repeated dose toxicity by the dermal route. Hence this end point was considered for waiver.
Based on the data available for the test chemical, 3-Nitrobenzoic acid (121-92-6) not likely to exhibit toxicity upon repeated exposure by oral, inhalation and dermal route of exposure.
Justification for classification or non-classification
Based on the above annotation and CLP criteria for the test chemical, 3-Nitrobenzoic acid (121-92-6) not likely to exhibit toxicity upon repeated exposure by oral, inhalation and dermal route of exposure.
