Executive summary:

The acute oral toxicity, repellency, and hazard potential of 998 chemicals to one or more of 68 species of wild and domestic birds was determined by standardized testing procedures. Redwinged blackbirds were the most sensitive of the bird species tested on a large number of chemicals, and an index based on redwing toxicity and repellency may provide an appropriate indication of the probability of acute avian poisoning episodes. Avian repellency and toxicity were not positively correlated (i.e. toxicity varied independently with repellency).

For triethylene tetraamine the LD50 was estimated based on the food consumption measured over a period of 18 hours. The LD50 is estimated at 101 mg/kg.

Description of key information

Key value for chemical safety assessment

Additional information

Wild-trapped birds were preconditioned to captivity for 2 to 6 weeks and were usually dosed by gavage with solutions or suspensions of the test chemical in propylene glycol. The LD50 was estimated based on the food consumption measured over a period of 18 hours. The LD50 (18 h) is estimated at 101 mg/kg bw.
