Description of key information

Additional information

Uronium hydrogen sulphate readily degrades to urea and sulfuric acid and/or sulfate ions in the environment.

Urea is considered to be readily biodegradable.

Sulfates (e.g. calcium sulphate) are inorganic substances and therefore will not undergo biodegradation i.e. microbial degradation to carbon dioxide and water, since they don’t contain any carbon or hydrogen atoms in their chemical formula. Sulfates will therefore undergo dissociation into sulfate ions and cations (e.g. Ca2+) only.
