- Statistics:
- Information regarding statistical analysis not provided.
- Preliminary studies:
- 1-Octene showed efficient absorption in the blood with extensive accumulation in the organs as compared to the iso-alkanes. Accumulation also was shown to increase with increasing carbon number. At day 3, concentrations of 1-octene were 12.4±0.5, 69.7±4.0, 78.9±9.7, 139.3±23.4, 720±176 μmol/kg in the blood, brain, liver, kidney, and fat, respectively. Concentrations of the 1-alkenes remained high in the fat even after the 12 hour recovery period, with 226±85 μmol/kg of 1-octene. According to the study authors, the extensive accumulation of 1-alkenes in the blood and organs as compared to other hydrocarbons may have toxicological significance and, therefore, products containing 1-alkenes should be handled cautiously to minimize inhalation exposure.
- Details on absorption:
- 1-Octene was efficiently absorbed into the blood.
- Details on distribution in tissues:
- 1-Octene was distributed in the following manner in the male Sprague-Dawley rats: fat>kidney>liver>brain>blood following measurements taken aft12 hours on exposure days 1, 2, and 3. However distribution in tissues following measurements taken 12 hours after exposure had ceased, indicated that fat had the highest concentration of 1-octene followed by the liver.
- Details on excretion:
- Data not provided
- Metabolites identified:
- not specified
- Conclusions:
- Interpretation of results (migrated information): other: Several organs showed bioaccumulation during exposure and following exposure cessation. However, no data are provided for bioaccumulation potential several days after exposure ended.
According to the study authors, the extensive accumulation of 1-alkenes in the blood and organs as compared to other hydrocarbons may have toxicological significance and, therefore, products containing 1-alkenes should be handled cautiously to minimize inhalation exposure. - Executive summary:
Male Sprague-Dawley rats were acclimatized for 4 to 6 days prior to exposure. Animals were housed 4/ cage with the number of cages limited to 4 per exposure chamber. Food and water were givenad libitum, except during exposure period. Animals were exposed to individual hydrocarbons selected for the experiment in six different experiments. The approximate concentration of the hydrocarbons (1 -alkenes andiso-alkanes) tested was 100 parts per million. All exposures occurred during daytime for 12 hours for 3 consecutive days. Concentrations of the hydrocarbons was measured in blood, brain, liver, kidney and perirenal fat immediately after 12 hour exposure on each exposure day, and 12 hours after the last exposure had been completed. The animals were removed one at a time from the exposure chamber and killed by decapitation. A standard process, not described in the article, made it possible to obtain blood and organ samples within 3 minutes of removal of animals from the exposure chamber.
Experimental results indicated that 1-octene was efficiently absorbed in the blood with extensive accumulation in the organs compared to the iso-alkanes. Accumulation also was shown to increase with increasing carbon number. At day 3, concentrations of 1-octene were 12.4±0.5, 69.7±4.0, 78.9±9.7, 139.3±23.4, 720±176 μmol/kg in the blood, brain, liver, kidney, and fat, respectively. Concentrations of 1-decene were 16.4±1.1, 138.1±2.7, 192.8±13.5, 162±22.9, and 2986±305 μmol/kg at day 3 in the blood, brain, liver, kidney, and fat, respectively. Concentrations of the 1-alkenes remained high in the fat even after the 12 hour recovery period, with 226±85 μmol/kg of 1-octene and 1971±134 μmol/kg of 1-decene. According to the study authors, the extensive accumulation of 1-alkenes in the blood and organs when compared to other hydrocarbons may have toxicological significance and, therefore, products containing 1-alkenes should be handled cautiously to minimize inhalation exposure.
