Thorough review of original documents was made regarding significant decrease of the number of sperms in males of F 1 generation and delay of estrous cycles in females that became the base of 3-Ministry GHS Classification in the second generation growth study, and effects of reproductive toxicities identified have all been of low level as the result. Therefore, it will be more appropriate to classify it in "Category 2" than classifing in "Category 1"on the assumption that there are effects on humans. | |

In the public comments it is pointed out that the observed neurotoxicity is acute toxicity rather than chronic toxicity. However, in a 90-day oral toxicity test in dogs in the work of Pozzani et al (1968), tonic convulsions, pulsus celer, polypnea and hind limb acratia were not observed immediately after exposure at doses within the range of guidance values for Category 1 (13.5 ppm group), but were observed from the 39th day of exposure. Therefore, it can be said that the symptoms in the central nervous system in this study are caused by repeated exposure. Moreover, in the public comments it is pointed out that there are no effects which apply to classification standards for toxicity, except for neurotoxicity. | |
