In human exposure studies, patch tests produced positive results (HSDB, 2003). Thus, the substance was classified into Category 1.
5 Germ cell mutagenicity Not classified - - - - Mouse spot tests, a kind of in vivo mutagenicity test using somatic cell, gave negative results (IUCLID, 2000). In addition, rats that received oral administration of the substance did not show chromosomal aberrations in bone marrow cells (IARC 30, 1983). Based on these results, the substance was classified into the "Not classified" category.

In oral and dermal applications of this substance to pregnant rats, malformations such as cardiac malformations, diaphragmatic hernias, and hydronephrosis were noted in pups that were born from exposed mothers at doses that did not show toxic effects in maternal animals (PDS 84 (1996)). In addition, hydrocephalus and microphthalmia were seen in progeny of mice that received oral administration of the substance during gestation (IARC 30 (1983)). Also, oral administration of the substance to pregnant rats was associated with increased fetal deaths and lowered postnatal survival rates. These reports demonstrated that clear cases of reproductive toxicity become apparent at doses that do not show maternal toxicity. Thus, the substance was classified into Category 1B.

P405: Store locked up.
P501: Dispose of contents/container to ...
A man exposed to commercial formulation of nitrofen complained of upper respiratory tract irritation (PDS 84, 1996), and acute toxic effects of this substance are mostly on respiratory tracts and the nervous system (IARC 30, 1983). Based on these reports, the substance was classified into Category 3 (respiratory tract irritation). Regarding its effect on the nervous system, details such as the relationship between the effects and doses were not found. Thus, classification was not carried out for the nervous system.

In agricultural workers who experienced excessive exposure to nitrofen, reduction in hemoglobin and leukocyte counts was noted (NTP TR 184, 1979), and chronic occupational exposure without protection resulted in central nervous system disturbances and anemia (HSDB, 2003). Based on these reports, the substance was classified into Category 1 (blood system) and Category 2 (nervous system).
10 Aspiration hazard Classification not possible - - - - No data available.
