Chloroform, generally regarded as a non-genotoxic compound, is associated with the induction of liver and/or kidney tumors in laboratory mice and rats. In particular, chloroform produced renal tubule tumors in low incidence in male Osborne-Mendel rats when administered by corn-oil gavage or in the

A recent study of the ability of chloroform in drinking water to produce cancer reported that male Osborne-Mendel rats developed renal tumors, but that female B6C3F1 mice failed to develop hepatocellular carcinomas. The results obtained in the male Osborne-Mendel rats were comparable to those

In a 2-year carcinogenesis bioassay, d-limonene (dL) induced kidney tumors in male F344 rats, but not in female F344 rats or either sex of mice, d-Limonene-1,2-oxide, a metabolite of dL, has been shown to bind reversibly the male rat-specific urinary protein, alpha2u-globulin (alpha 2u-G), lysosomal

Dimethyl methylphosphonate (DMMP), a chemical that has been used as a flame retardant and as a nerve gas simulant to mimic the physical but not biologic properties of nerve gases, was administered by gavage in corn oil for up to 2 years at doses of 0, 500, or 1000 mg/kg/day to male and female F344/N

Long-term toxicity and carcinogenicity of phenylbutazone, a nonsteroidal anti-inflammatory drug, were evaluated in F344/N rats and B6C3F1 mice. In 2-year studies, phenylbutazone was given in corn oil by gavage 5 days per week to groups of 50 rats of each sex at doses of 0, 50, or 100 mg/kg body

Male rats are more sensitive to the nephrocarcinogenic effect of hexachlorobenzene (HCB) than are female rats. The purpose of this study was to shed light on this phenomenon by investigating mechanisms of subchronic nephrotoxicity of HCB. Groups of rats were administered HCB in corn oil (po) at 100

C.I. Acid Orange 3 is a dinitrodiphenylamine derivative used exclusively as a dye (up to 0.2%) in semipermanent hair coloring products. This study was one of a series on semipermanent hair dyes, which included HC Blue No. 1 (NTP TR 271), HC Blue No. 2 (NTP TR 293), HC Red No. 3 (NTP TR 281), and

The relationship between the acute toxicity of orally-administered chloroform and its long-term tumorigenic potential was studied in male mice of the CFLP outbred Swiss albino mouse strain. A single dose of approximately 18 mg CHCl3/kg had no detectable acute toxic effect on the liver or kidneys and

o-Benzyl-p-chlorophenol is an aryl halide biocide with widespread use in hospitals and households as a broad-spectrum germicide in disinfectant solutions and soap formulations for general cleaning and disinfecting. Human exposure to o-benzyl-p-chlorophenol occurs by absorption through the skin and

In order to clarify the etiology of a dose-related increase in the incidence of tubular cell adenocarcinomas of the kidney in male rats, the nephrotoxicity of p-dichlorobenzene (p-DCB) was investigated in a subchronic study. Groups of ten male and ten female Fischer 344 rats were dosed by gavage

Geranyl acetate (3,7-dimethyl-2,6-octadiene-1-ol acetate) is a colorless liquid prepared by fractional distillation of selected essential oils or by acetylation of geraniol. It is a natural constituent of more than 60 essential oils, including Ceylon citronella, palmarosa, lemon grass, petit grain,

Dimethyl methylphosphonate (DMMP) is a widely used chemical. Diethyl ethylphosphonate (DEEP) has been proposed as a replacement for DMMP in several applications. A long-term carcinogenesis study with DMMP in rats and mice showed a significant increase in the incidence of kidney tumors after 2 years

Hexachloroethane is used in organic synthesis as a retarding agent in fermentation, as a camphor substitute in nitrocellulose, in pyrotechnics and smoke devices, in explosives, and as a solvent. In previous long-term gavage studies with B6C3F1 mice and Osbourne-Mendel rats (78 weeks of exposure

Trichloroethylene (TCE) is an industrial solvent used for vapor degreasing and cold cleaning of fabricated metal parts. TCE has also been used as a carrier solvent for the active ingredients of insecticides and fungicides, as a solvent for waxes, fats, resins, and oils, as an anesthetic for medical

The National Cancer Institute and National Toxicology Program have performed 2-year toxicology and carcinogenesis studies with a number of ethanes substituted with chlorine or bromine. A review of the results of studies with these halogenated ethanes has revealed several consistencies between the
