N deposition :: Freshwater Sponges

Latin name: 

Porifera

Impact Type: Deposition of pollutant

Key Concerns:

There is evidence from research work in Germany that increased nitrite concentrations have a detrimental effect on the growth and repoduction of freshwater sponges (Kahlert & Neumann 1997). However there is no published research available for Britain and Northern Ireland.

Additional Comments:

None
