Description of key information

The DAR (2008) reviewed six studies assessing the toxicity of aluminium on seven different bird species. Presumed NOEL for aluminium values from short term toxicity studies are as follows: - Japanese quail 0.05% in the diet - Chickens 0.1% in the diet - Doves 0.1% in the diet - Juvenile doves 59.2 mg/day corresponding to 994.6 mg aluminium ammonium sulfate/day - Ducks 197.4 mg/day corresponding to 3.32 g aluminium ammonium sulfate/day On the basis of these studies it is evident that at high concentrations aluminium can have adverse effect in dietary studies on some species of birds. However, the dose rates employed are extremely high, far higher than would be expected to occur in practice. ATSDR (2008) reported natural occurring concentrations ranging from 0.4 to 6.1 mg/kg in fish and from 23 to 115 in shellfish. Environment Canada (2010) reported that benthic invertebrates (primarily insect larvae) and salmon fry residing in the Chilliwack watershed of British Columbia, both key dietary items for the birds, contained mean concentrations of around 1,500 mg/kg dw and 165 mg/kg dw, respectively. The samples were collected over the period 1999 to 2001, and were considered to represent overall exposure to both natural and anthropogenic sources in the region. Moreover, according to the literature, both aluminium and ammonium have a low potential of bioaccumulation. Based on these results, it can be postulated that under the proposed conditions of use no adverse effects on birds populations would result from the use of aluminium ammonium sulfate.
