The NTP has released its finalised technical report on the toxicology (including genotoxicity and carcinogenicity) of β‑picoline. Two-year drinking water studies indicated “clear evidence of carcinogenic activity” in female mice (increased incidences of liver and lung tumours), “equivocal evidence” in male mice (equivocal findings related to incidences of lung tumours), “some evidence” in female rats (increased incidences of lung tumours) and “no evidence” in male rats. No evidence of genotoxicity was seen in Ames or in vivo micronucleus tests.
