Description of key information

Phthalylsulfathiazole was 50% biodegradable in water in 38 days (half-life) indicating that phthalylsulfathiazole is readily biodegradable in water.

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

Based on level III fugacity model the half life period of Phthalylsulfathiazole was estimated. Phthalylsulfathiazole was 50% biodegradable in water in 38 days (half-life) indicating that phthalylsulfathiazole is readily biodegradable in water since the half life is less than the threshold of 60 days (to qualify the chemical as persistent)
