Description of key information

The lowest freshwater 96-h LC50 (693 µg V/L)  was observed for the acute effect of V2O5-flakes on Leuciscus idus (Mitterer, 1999; Klimisch 2). For the marine environment, a 96h-LC50 of 27800 µg V/L was reported for the acute toxicity of NH4VO3 to Limanda limanda (Taylor et al., 1985; Klimisch 2).

Key value for chemical safety assessment

LC50 for freshwater fish:
693 µg/L
LC50 for marine water fish:
27 800 µg/L

Additional information

Reliable studies (Klimisch 1 or 2) are available for the acute toxicity of 5 V substances (NaVO3, NH4VO3, Na3VO4, V2O5, and ammonium polyvanadate) to 12 freshwater fish species (Brachydanio rerio, Poecilia reticulata, Oncorhynchus mykiss, Oncorhynchus tshawytscha, Catostomus latipinnis, Gila elegans, Leuciscus idus, Pimephales promelas, Ptychocheilus lucius, Salvenius fontinalis, Xyrauchen texanus and Gasterosteus aculeatus) and one marine species (Limanda limanda). For the freshwater environment the acute 96h-LC50 values range between 693 and 118000 µg V/L. The lowest 96-h LC50 was observed for the acute effect of V2O5-flakes on Leuciscus idus (Mitterer, 1999; Klimisch 2). Reliable freshwater data do not differ significantly among vanadium substances tested: sodium orthovanadate (range: 3170-16500 µg V/L), sodium metavanadate (range: 2200-11500 µg V/L), ammonium polyvanadate (4101 µg V/L) and vanadium pentoxide (range: 693-118000 µg V/L).

For the marine environment, a 96h-LC50 of 27800 µg V/L was reported for the acute toxicity of NH4VO3 to Limanda limanda (Taylor et al., 1985; Klimisch 2). All results are based on total dissolved V concentrations.
