Materials and methods

Principles of method if other than guideline:

The study was conducted according to an internal BASF method. Test groups consisting of 5 animals/sex/group were treated with several doses of an aqueous suspension of the test substance applied intraperitoneally. After exposure, the animals were observed for a period of 14 d within which time signs of clinical toxicity as well as mortality were monitored and recorded. Animals found dead during the observation period were subjected to necropsy. At conclusion, the surviving animals were also sacrificed for the purpose of necropsy. The LD50 value was estimated on the basis of the observed mortalities.

Results and discussion

Effect levels

Sex:

male/female

Dose descriptor:

LD50

Effect level:

> 2 000 mg/kg bw

Remarks on result:

not determinable due to absence of adverse toxic effects

Mortality:

No mortality of 5 males and 5 females per dose was seen.

Clinical signs:

Some symptoms of poisoning (dyspnoea, apathy, spastic walk, stretching, unkempt fur, exsiccosis and poor general condition) were noted within the first 5 hours after application of the test substance. Green unkempt fur and green urine were seen in the 2000 mg/kg bw group on day 3 and 4.

Body weight:

The body weight gain was within the normal range, details can be seen in "Remarks on results including tables and figures".

Gross pathology:

Autopsy revealed incorporation of substance in the abdomen and coloration of fat tissue.
