Comments: Limit of quantification of Hydrazine: 0.01 mg/L
- the following DT50 values for the dissipation of hydrazine hydrate in surface water can be derived:
Gravel pit: approximately 2.7 h
River Rhine: approximately 23 h
Applicant's summary and conclusion
- Executive summary:
Investigating the stability of hydrazine in two natural surface waters, DT50 values of approximately 2.7 h and 23 h can be observed, respectively (Currenta, 2010).
