From the water surface the substance will not evaporate into the atmosphere.
Key value for chemical safety assessment
Additional information
Volatilisation from water can be excluded. "The volatility of hydroxylamine is also very low. Using the model EPIWIN, the Henry coefficient is calculated 0.0007 Pa m³/mol and the SPARC model reveals a value of 0.025 Pa m³/mol. Emissions into the atmosphere can be excluded. " EU-RAR Draft, 14. May 2008 These assumptions may be also considered for hydroxylamine. This is underlined by the high water solubility and low vapour pressure of hydroxylamine.
