Description of key information

The results from two acute fish toxicity assays indicate the short-term toxicity of 4-vinylpyridine (4VP). The key study was a 96-hour acute fish assay in Oryzias latipes, resulting in a 96-h LC50 of 1.04 mg/L. This value was supported by a 48-h LC50 of 1.57 mg/L, from a study conducted as part of a fish bioconcentration assay.
