- Details on inhalation exposure:
- - Generation of the inhalation atmosphere: A dust aerosol was generated by means of a dosing-wheel dust generator (Gericke/BASF). The test substance was mixed with 1 wt% of Aerosil in order to achieve a more uniform dust concentration in air. The concentration was adjusted by varying rotation of the metering disc.
- The following air flow (supply air) was set: compressed air : 1500 L/h. The exposure system was placed in an air-conditioned laboratory. Temperatures in the exposure system were 19 - 25°C. By means of an exhaust air system the pressure ratios in the inhalation system were adjusted in such a way that the amount of exhaust air was about 10% lower (excess pressure). This ensured that the mixture of test substance and air was not diluted with laboratory air in the breathing zones of the animals.
Analytical method used: Gravimetric determination of the inhalation atmosphere concentration. The preweighed filter was placed into the filtration
equipment. By means of a vacuum compressed air pump a volume of the dust aerosol was drawn through the filter. The dust concentration in mg/L was calculated from the difference between the preweight of the filter and the weight of the filter after sampling, with reference to the sample volume of the inhalation atmosphere. The concentration was corrected for the amount of the additive (1 sample about hourly). - Analytical verification of test atmosphere concentrations:

- Duration of exposure:

- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: Body weight was checked before the beginning of the test, after 7 days and at the end of the observation period. Clinical findings were recorded several times during exposure and at least once on each workday in the observation period. A check for dead animals was made daily.
- Necropsy of survivors performed: yes, at the end of the 14-day observation period the animals were sacrificed with CO2 and were subjected to gross-pathological examination. - Statistics:

Additional information
Acute oral toxicity
In an acute oral toxicity study, performed similarly to OECD guideline 401, 10 Gassner rats per sex per dose were exposed to 1000, 1250, 1600, 2000, 2500, 3200 and 4000 mg/kg bw of the test substance (BASF 1971). No mortality occurred in the 1000 mg/kg group. One animal died in the 1250 and 1600 mg/kg group. In the 2000 mg/kg group 3 animals died and 16, 19 and 20 in the 2500, 3200 and 4000 mg/kg exposure groups respectively. The observation period after exposure was only 7 days instead of the recommended 14 days. However, almost all mortality occured within the first 24 hours. Additional mortality after 7 days is therefore likely to be minimal. A time depended change in LD50 value is not expected.
Acute inhalation toxicity
In an acute inhalatory toxicity test performed according to OECD guideline 403, 5 Wistar rats per sex were exposed to 5.4 mg/L anthranilamide as aerosol (BASF 1990). After the 14-day observation period no mortality had occurred. During exposure accelerated respiration was observed while after the 4 hour exposure period animals showed accelerated respiration, reddish nasal and eye discharges (blood test positive), and discolored fur. These effects were absent one day after exposure. No pathological findings were noted. The LC50 was determined to be greater than 5.4 mg/L air.
In an additional acute inhalation study in which the inhalatory toxicity of the test substance was assessed, 6 male and 6 female rats were exposed to 0.009 mg test substance/L air for 8 hour (BASF 1971). No mortality occurred and no clinical signs were observed. No gross pathology findings were noted.
Justification for classification or non-classification
Based on an oral LD50 in rats of > 2200 mg/kg bw classification for acute oral toxicity is not warranted in accordance with EU Classification, Labeling and Packaging of Substances and Mixtures (CLP) Regulation No. 1272/2008.
Based on an inhalation LC50 of > 5.4 mg/L air classification for acute inhalation is not warranted in accordance with EU Classification, Labeling and Packaging of Substances and Mixtures (CLP) Regulation No. 1272/2008.
