CLASS METHOD (if applicable)
- Rationale for the selection of the starting dose: TThe starting dose can be selected from the fixed dose levels of 5, 50, 300, and 2000 mg/kg body weight. Available information indicated that the test item was likely to be non-toxic regarding acute toxicity therefore we chose a dose of 2000 mg of Zinc chlorohydroxy sulphate and copper sulphide, precipitation per kg body weight to be used as a starting dose. In the first step, one group of 3 females was dosed. The test item in limit dose did not cause mortality for 48 hours and therefore, in a second step, another 3 females were treated at the same dose level.- Doses:
- 2000 mg Zinc chlorohydroxy sulphate and copper sulphide, precipitation/kg body weight was used as a starting dose
- No. of animals per sex per dose:
- In the first step, one group of 3 females was dosed. The test item in limit dose did not cause mortality for 48 hours and therefore, in a second step, another 3 females were treated at the same dose level.
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days.
- Frequency of observations and weighing: The animals will be observed individually immediately after the administration of the test item and then 0.5, 1, 2 and 4 hours later. Each animal will be inspected daily for the next 14 days. Individual weights of animals will be determined shortly before the test item is administered and at least weekly thereafter.
- Necropsy of survivors performed: yes
- Other examinations performed: clinical signs, body eight, gross necropsy - Key result
- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No mortality was observed during the study.
- Clinical signs:
- No signs of intoxication, change of health, nor any other adverse reactions during 24 hours and 14-days observation period at limit dose of 2000 mg/kg body weight was observed. Animals No 1-3 exhibit slight piloerection after 2 hours from administration and went to normal behavior in 2 hours.
- Body weight:
- The body weight gain shown by the animals over the study period was considered to be similar to that expected for normal untreated animals of the same age and strain.
- Gross pathology:
- No abnormalities were found at macroscopic post mortem examination of the animals.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The oral LD50 value of Zinc chlorohydroxy sulphate and copper sulphide, precipitation in Wistar rats was established to exceed 2000 mg/kg body weight.
- Executive summary:
The purpose of the study was to evaluate the potential toxic effect of the test item “Zinc chlorohydroxy sulphate and copper sulphide, precipitation” when administered as a single oral dose to Wistar rats.
The procedure according to OECD Guideline 423 Acute Toxic Class (ATC) method was used. A limit dose of 2000 mg/kg body weight was used as a starting dose. Available information indicated that the test item is likely to be non-toxic regarding acute toxicity, therefore, a limit dose of2000 mg/kg body weight was used as a starting dose.
In the first step, one group of 3 females was dosed. The test item at this dose did not cause death in the next 48 hours and therefore another 3 females were treated at the same dose level. The test item Zinc chlorohydroxy sulphate and copper sulphide, precipitation administered to 6 females Wistar rats at a limit dose of 2000 mg/kg did not induce signs of intoxication, change of health, nor any other adverse reactions during 14-days observation period. During necropsy we did not observe any macroscopic findings in all Animals at this dose level. The LD50 of the test item “Zinc chlorohydroxy sulphate and copper sulphide, precipitation” is greater than 2000 mg/kg body weight after single oral administration to Wistar rats.
Based on Annex 2d Test Procedure with a Starting Dose of 2000 mg/kg body weight of OECD Guideline 423 it can be concluded that the test item Zinc chlorohydroxy sulphate and copper sulphide, precipitation is classified in GHS Category 5 – Unclassified. Limit test with dose of 5000 mg/kg body weight was not conducted.
