| Reactivity Profile | DECALDEHYDE is an aldehyde. Aldehydes are frequently involved in self-condensation or polymerization reactions. These reactions are exothermicthey are often catalyzed by acid. Aldehydes are readily oxidized to give carboxylic acids. Flammable and/or toxic gases are generated by the combination of aldehydes with azo, diazo compounds, dithiocarbamates, nitrides, and strong reducing agents. Aldehydes can react with air to give first peroxo acids, and ultimately carboxylic acids. These autoxidation reactions are activated by light, catalyzed by salts of transition metals, and are autocatalytic (catalyzed by the products of the reaction). The addition of stabilizers (antioxidants) to shipments of aldehydes retards autoxidation. |

| Körperbelastung | Expired air samples, obtained from an urban population of 28 normal healthy humans, contained decaldehyde at 0.4 ng/L in approximately 63% of the samples(1). Expired air samples were collected from 62 human subjects (20 controls, 14 prediabetics, and 28 diabetics)decaldehyde was identified only in the samples from prediabetic sources(2). 43 of 46 human adipose tissue samples contained decaldehyde at unreported concentrations(3). Decaldehyde was found in 15 of 15 personal air samples at a mean concentration of 1.2 ppb from samples taken in Helsinki, Finland, tested May to September 1997(4). Decaldehyde was detected in 2 of 8 human mother's milk samples (unreported concentrations) collected in Bayonne, NJ, Jersey City, NJ, Pittsburgh, PA, Baton Rouge, LA, and Charleston, WV(5). |
| Treatment | Kidney dialysis is usually needed to relieve the symptoms of uremic syndrome until normal kidney function can be restored. |
| Wechselwirkungen | Environment-selective synergistic toxicity using combinations of aldehydes and hydrazine derivatives was demonstrated in two different model systems in vitro. Combinations of 5-nitro-2-furaldehyde with semi-carbazide and of 2-hydrazinopyridine with pyridine-2-carboxaldehyde, which can react in situ to form antimicrobial hydrazones, demonstrated greater degrees of synergism against the intracellular pathogen, Salmonella typhimurium, at pH 5 relative to pH 7.4. Combinations are more selectively toxic at pH 5 (vs pH 7.4) than individual precursors and preformed hydrazone products because acid catalysis of hydrazone formation plays a role only for the combinations. A combination of decanal and N-amino, N'-octylguanidine (AOG) exhibited more pronounced synergistic cytolytic activity against erythrocytes in 0% serum than in 1% serum. Serum protein binding of decanal inhibited the formation of the more cytotoxic hydrazone, N-decylidenimino,N'-1-octylguanidine (DIOG), from the less cytotoxic AOG and decanal, and serum protein binding of DIOG prevented this cytotoxin from reaching the cell membrane. Because decanal binding cannot play a role in the cytotoxicity of preformed DIOG, it was less selective for cells in 0% serum than the combination of AOG and decanal. The pH 5 and 0% serum environments represent very simple models for macrophage phagolysosomal compartments and poorly vascularized solid tumor interiors respectively. If environment-selective synergism can be used as a basis for target-selective synergism in other in vitro model systems and in vivo, self-assembling combinations could provide a basis for rational introduction of target-selective synergism into chemotherapeutic drug design.Decanal and N-amino-N'-1-octylguanidine (AOG), combined at 28 microM each, mediated erythrocyte lysis within 80 minutes under physiological conditions. By contrast, no lysis was observed after 20 hours with either decanal (56 microM) or AOG (100 microM) alone. The pronounced synergism observed for these chemicals and similar reactive pairs of chemicals is due to the self-assembly of more cytotoxic hydrazones in situ. Decanal and AOG also exhibit synergistic activity against cultured human cells (HeLa) and bacteria (Escherichia coli J96). This synergism may be useful in the design of cytotoxins that would self-assemble selectively from nontoxic precursors within tumors, while sparing normal tissue. |

| Umweltverhalten | TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 70(SRC), determined from a structure estimation method(2), indicates that decaldehyde is expected to have high mobility in soil(SRC). Volatilization of decaldehyde from moist soil surfaces is expected to be an important fate process(SRC) given a Henry's Law constant of 1.8X10-3 atm-cu m/mole(3). Decaldehyde is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 0.103 mm Hg at 25 °C(4). Utilizing the BOD5 screening test, decaldehyde reached 22% theoretical BOD in 5 days using a sewage inoculum(5), suggesting that biodegradation is an important environmental fate process in soil(SRC).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 70(SRC), determined from a structure estimation method(2), indicates that decaldehyde 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 1.8X10-3 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 2 hours and 5 days, respectively(SRC). According to a classification scheme(5), an estimated BCF of 140(SRC), from an estimated log Kow of 3.76(2) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is high(SRC). Utilizing the BOD5 screening test, decaldehyde reached 22% theoretical BOD in 5 days using a sewage inoculum(6), suggesting that biodegradation is an important environmental fate process in water(SRC).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), decaldehyde, which has a vapor pressure of 0.103 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase decaldehyde 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 1 day(SRC), calculated from its rate constant of 3.5X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Decaldehyde does not contain chromophores that absorb at wavelengths >290 nm(4) and, therefore, is not expected to be susceptible to direct photolysis by sunlight(SRC). |
| Lebensmitteluntersuchungswerte | Hamburger (15.5% fat), which had been fried, had a fine aerosol emission rate of 1.9 mg decaldehyde/kg meat(1). Extra lean and regular hamburger, which had been char broiled, had a fine aerosol emission rate of 8.9 and 12.4 mg decaldehyde/kg meat, respectively(1). Decaldehyde was identified as a volatile component of raw beef(2) and roasted filberts(3). Decaldehyde was identified in concentrated aqueous orange essences(5), in fresh-squeezed orange and pineapple juice at concentrations from 0.016-0.50 ppm(6), in kiwi fruit flowers(8), and in a steam distillate of Kogyoku apple juice(10). Bisbee Delicious apples from Washington State emitted increasing concentrations of decaldehyde through the end of August (to 992.7 pL/kg-hr)concentrations decreased in apples harvested after this point (to 77.9-208.3 pL/kg-hr) but increased in apples harvested in early October (to 910.3 pL/kg-hr)(4). Decaldehyde is present, at unreported concentrations, as a volatile component of aroma of cooked beef, mutton, chicken, and pork(7). Cold-pressed oils from Florida and California citrus (oranges, tangerines, grapefruits) contained decaldehyde from 0.131-0.415 wt%(9). Decaldehyde was found in popcorn using dry extraction method at 29 ug/kg(11). Decaldehyde was identified as a volatile component in unpasteurized, fresh orange juice samples at concentrations of 0.16-0.45, 0.50, and 0.18 ppm in mechanically pressed valencia, pineapple, and ambersweet oranges, respectively(10)concentrations of 0.016, 0.022, 0.019-0.021, 0.057-0.29, 0.057, and 0.043 ppm were measured in hand pressed valencia, pineapple, hamlin, navel, pera, and ambersweet oranges, respectively(12). |

| Toxizitätsübersicht | IDENTIFICATION AND USE: Decaldehyde (Decanal) is a colorless to light-yellow liquid. The main use of decanal is for citrus tones and for the manufacture of synthetic citrus oils. In addition, the C10 aldehydes have value as intermediates in the synthesis of pharmaceuticals and in the polymer and pesticide fields. In the aircraft cabin, decanal was produced in the presence of ozone from surface reactions with occupants and their clothing, consistent with the inference that occupants were responsible for the removal of >55% of the ozone in the aircraft cabin. HUMAN EXPOSURE AND TOXICITY: Decanal was cytotoxic to Hela cells with IC50 less than 20 ug/mL. ANIMAL STUDIES: Decanal demonstrated antifungal and bactericidal properties. ECOTOXICITY STUDIES: Decanal did not significantly affect survival or hatching success of the brine shrimp Artemia salina.Uremic toxins such as decanal are actively transported into the kidneys via organic ion transporters (especially OAT3). Increased levels of uremic toxins can stimulate the production of reactive oxygen species. This seems to be mediated by the direct binding or inhibition by uremic toxins of the enzyme NADPH oxidase (especially NOX4 which is abundant in the kidneys and heart) (A7868). Reactive oxygen species can induce several different DNA methyltransferases (DNMTs) which are involved in the silencing of a protein known as KLOTHO. KLOTHO has been identified as having important roles in anti-aging, mineral metabolism, and vitamin D metabolism. A number of studies have indicated that KLOTHO mRNA and protein levels are reduced during acute or chronic kidney diseases in response to high local levels of reactive oxygen species (A7869). |
| Ökotoxizitätsauszüge | /AQUATIC SPECIES/ Water soluble algal extracts, the aldehydes 2E,4E-decadienal, decanal, undecanal and the fatty acid eicosapentaenoic acid (EPA) were assayed for toxicity to hatching success and larval mortality of the brine shrimp Artemia salina. ... Decanal did not significantly affect survival or hatching success at the concentrations tested. Undecanal and EPA showed a limited toxic effect in naupliar mortality trials. We suggest that 72 hr Artemia exposure trials represent an acceptable bioassay for diatom toxicity where alternative bioassays are unavailable. |
| Plant Concentrations | Decaldehyde was detected in the emissions from 4 of 19 vegetation species from the Fernbank Forest in Atlanta, GA(1). Emission rates of 0.3, 0.2, 0.3, and 0.5 ugC/hr-gram dry weight from Basswood, Eastern hemlock, American Beech, and Slippery Elm, respectively, were reported(1). Decaldehyde has been detected in emissions from the oak species Quercus ilex at Castel Porziano, Rome, Italy on June 1993 between the hours of 11 am to 1 pm(2). In northeast Spain decaldehyde was detected in the volatiles of Pinus halepensis during the 1997 spring and summer seasons at emission rates of 0.55 and 2.80 ug/gDM/hr, respectively, and in Bupleurum fruiticosum during the 1997 summer season at an emission rate of 1.97 ug/gDM/hr(3).Decaldehyde detections in plants(1).[Table#986] |
