Description of key information

There are no long-term toxicity data for birds. In accordance with Column 2 of REACH Annex X, long-term and reproductive toxicity testing with birds (required in Section 9.6) is not needed as the chemical safety assessment according to Annex I indicates that this is not necessary.

A short-term (14-day) LC50 value of >565 mg active acid/kg bw has been determined for the effects of ATMP-H on mortality of Anas platyrhynchos.

A short-term (14-day) LD50 value of >2510 mg/kg bw/day, equivalent to >565 mg active acid/kg bw/day, has been determined for the effects of ATMP-H on mortality of Colinus virginianus.

Key value for chemical safety assessment

Additional information

Two short-term toxicity tests (14-day) are available with Anas platyrhynchos and Colinus virginianus during which no mortalities were recorded up to the highest treatment. Therefore the EC50s were >565 mg active acid/kg bw. However neither have been selected as key since ECHA (2008, Guidance on information requirements and chemical safety assessment Part B: Hazard Assessment May 2008, version 1.1) reads: "due to poor correlation between short- and long-term effects, only long term studies are considered suitable for CSA purposes".

Studies on long-term or reproductive toxicity to birds do not need to be conducted due to the availability of relevant existing mammalian data from which a PNECoral and a risk characterisation ratio <1 have been derived.
