Additional information

Synthetic, crystalline, non-fibrous, silica and titanium based zeolite is an inorganic solid which is insoluble in n-octanol.

The molecular weight of synthetic, crystalline, non-fibrous, silica and titanium based zeolite is > 800 g/mol (in the range of 5000 - 6000 g/mol), so biological membranes could not be permeated. Therefore bioaccumulation in aquatic organisms is not to be expected. The studies from Fischer and Gode (1977) confirmed this conclusion.

In summary,

  • phototransformation in air
  • biodegradation and
  • bioaccumulation

is not a critical and relevant process for environmental fate and pathways.
