Description of key information
The PBT Profiler & EPI Suite has estimated that 5-nitrosalicylic acid is expected to be found predominantly in soil and its persistence estimate is based on its transformation in this medium. Its half-life in soil, 30 days.,does not exceeds the threshold (60 days) of being persistent in soil.Therefore, 5-nitrosalicylic acid is estimated not to be persistent in the soil environment.Though 5-nitrosalicylic acid shall diffuse to the extent of 76% in the soil medium, the ready bio-degradability will ensure that the chemical shall be non-persistent in the soil.
Key value for chemical safety assessment
- Half-life in soil:
- 30 d
- at the temperature of:
- 25 °C
Additional information

By applying weight of evidence approach the target chemical found to be readily biodegradable with half life 28.399 to 30 days. does not exceeds the threshold (60 days) of being persistent in soil Thus it is concluded that 5-nitrosalicylic acid is biodegradable in soil.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
