Absorption, Distribution and Excretion · 5 件

...It is absorbed by GI tract, lung, and through the skin.

When rats were exposed by inhalation to 100, 300, or 600 ppm 6 hr/day, 5 days/week for 7 weeks, 1-pentanol was found in the brain at 0.2, 1.4, and 3.2 ppm, respectively. Similar but smaller values were found in rats exposed to the same concentrations for 14 weeks. 1-Pentanol is oxidized by alcohol dehydrogenase to /the aldehyde, and the aldehyde is then oxidized by aldehyde dehydrogenase to/ valeric acid in rats, and it can undergo further oxidation or be excreted in the urine.

After an oral dose of 0.5, 1, or 2 g/kg of 1-pentanol, the maximal blood levels in mice occurred at 10 min and were nonlinear. The blood levels were 7, 11, and 16 mg/dL, respectively. No 1-pentanol could be found in the blood after 4 hr.

Rats given 1g/kg of 1-pentanol (0.25 g at 15-min intervals) by intraperitoneal injection showed a peak blood concentration of about 21 mg% 1 hr after dosing started and disappearance from the blood after 3.5 hr. Only 0.88% and 0.29% were excreted in the expired air and urine, respectively. Rats given a 2-g/kg oral dose of 1-pentanol had a peak blood concentration of 20 to 25 mg% in 1 hour and essentially none after 4 hr. No alcohol was detected in the urine.

Disposal Methods · 3 件

SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.

The following wastewater treatment technologies have been investigated for pentanol: Activated carbon.

Amyl alcohol is a waste chemical stream constituent which may be subjected to ultimate disposal by controlled incineration.

Environmental Fate · 3 件

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 160(SRC), determined from a log Kow of 1.51(2)and a regression-derived equation(3), indicates that n-pentyl alcohol is expected to have moderate mobility in soil(SRC). Volatilization of n-pentyl alcohol from moist soil surfaces is expected to be an important fate process(SRC) given a Henry's Law constant of 1.3X10-5 atm-cu m/mole(4). The potential for volatilization of n-pentyl alcohol from dry soil surfaces may exist (SRC) based upon a vapor pressure of 2.2 mm Hg(5). Screening studies using sewage inoculum(6-9) suggest that n-pentyl alcohol will readily degrade in soils under aerobic and anaerobic conditions(SRC).

AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 160(SRC), determined from a log Kow of 1.51(2) and a regression-derived equation(3), indicates that n-pentyl alcohol is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon a Henry's Law constant of 1.3X10-5 atm-cu m/mole(4) Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 43 hours and 23 days, respectively(SRC). According to a classification scheme(5), an estimated BCF of 3(SRC), from its log Kow(2) and a regression-derived equation(6), suggests the potential for bioconcentration in aquatic organisms is low(SRC). The rate constant for the reaction of n-pentyl alcohol with hydroxyl radicals in aqueous solution has a maximum value of 4.8X10+9/M-sec at a pH of 5(7,8). Based on this rate constant and a value of 10-17 M for the concentration of hydroxyl radical in eutrophic water(9), the half-life of n-pentyl alcohol due to this reaction can be estimated to be 56 days. Therefore, this reaction should not be important in water(SRC). Biodegradation tests of n-pentyl alcohol with sewage and activated sludge(10-13) indicate that aerobic biodegradation will occur in natural water. Biodegradation tests under anaerobic conditions(14,15) suggests that biodegradation of the compound should occur in anaerobic water and sediment(SRC).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), n-pentyl alcohol , which has a vapor pressure of 2.2 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase n-pentyl alcohol is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 2 days(SRC), calculated from its rate constant of 1.1X10-11 cu cm/molecule-sec at 25 °C(3).

Food Survey Values · 1 件

Unspecified isomer(s) of pentyl alcohol were detected in volatile components of fried chicken(6). n-Pentyl alcohol was detected at a mean concn 0.008 mg/kg in dry beans, at 0.019 mg/kg in dry split peas and at 0.095 mg/kg in dry lentils(2). n-Pentyl alcohol was detected at concns of 454-1267 ug/kg in commercial soybean curds(11). n-Pentyl alcohol was identified, not quantified, in blue cheese(12).

Ecotoxicity Excerpts · 1 件

/AQUATIC SPECIES/ This study describes effects of selected nonpolar narcotics of varying hydrophobicity (quantified by the 1-octanol-water partition coefficient, log Kow) and molecular structure on the population growth kinetics of the freshwater ciliate Tetrahymena pyriformis. The response of Tetrahymena exposed to different nonpolar narcotics varied from a change in generation time to a change in lag phase with similar generation time compared to control. Two narcotics with high (>3.00), intermediate (>0.00 and <3.00), and low log Kow (<0. 00) values were tested. Growth of Tetrahymena inhibited up to 85% by the high log Kow toxicants (2-decanone and butylbenzene) grew with similar rates as the control, but exhibited increased lag time, suggesting that the protozoan became acclimated to toxicant stress. Results from growth of Tetrahymena in the low log Kow toxicants (ethanol and acetone) indicate an increased generation time with increasing concentration. Cells inhibited by the intermediate log Kow chemicals, 1-pentanol and anisole, exhibited a response that was a combination of the previously mentioned two contrary responses. Cells inhibited <35% with 1-pentanol and <50% with anisole grew with similar generation times as control flasks, whereas in cells inhibited >35% or >50%, respectively, the doubling times were longer than control growth.

Soil Adsorption/Mobility · 1 件

The Koc of n-pentyl alcohol is estimated as 160(SRC), using a log Kow of 1.51(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that n-pentyl alcohol is expected to have moderate mobility in soil.
