Brevetoxins are potent neurotoxins produced by the marine dinoflagellate Karenia brevis. Exposure to brevetoxins may occur during a K. brevis red tide when the compounds become aerosolized by wind and surf. This study assesses possible adverse health effects associated with short-term inhalation exposure to brevetoxin 3. Male F344/Crl/Br rats were exposed to 500μ g brevetoxin 3/m3 by nose-only inhalation for 0.5 or 2h/d for 5 consecutive days. Control rats were sham exposed for 2h to vehicle. Calculated deposited brevetoxin doses were 8.3 and 33μ g/kg/d for the low- and highdose groups, respectively.
