Ammonia :: Bats

Latin name: 

Impact Type: Direct exposure to pollutant

Key Concerns:

Bats themselves are unlikely to be adversely affected by atmospheric ammonia as peak concentrations of up to 1779 ppm (0.96 mg/dm3) have been recorded at a bat roost (McFarlane et al. 1995).

Additional Comments:

70% of bats feed on insects and occasionally other small invertebrates and some feed on pollen. NH3 is unlikely to have a detrimental impact on the food source. Greater threats come from loss of roosts as many have been destroyed to make way for buildings and roads. The use of pesticides (including in buildings), felling of old woodland, drainage of wetlands and removal of hedgerows have all been detrimental for bats.
