Carcinogenesis Studies of 2,2-bis(Bromomethyl) -1,3-Propanediol, Nitromethane, and 1,2,3-Trichloropropane (CAS Nos. 3296-90-0, 75-52-5, and 96-18-4) in Guppies (Poecilia reticulata) and Medaka (Oryzias latipes) (Waterborne Studies) Technical rept

摘要

The NTP chose to initiate studies in fish as an exploration of alternate or additional models for examining chemical toxicity and carcinogenicity. The use of small fish species in carcinogenicity testing offered potential advantages as a bioassay test system, including significant savings in cost and time over rodent studies. Large numbers of small fish could be easily maintained in a limited area. The two species chosen for study were guppy (Poecilia reticulata) and medaka (Oryzias latipes), both of which are hardy, easily maintained, and have a low occurrence of background lesions.
