  • Health Effects: Chronic exposure to uremic toxins can lead to a number of conditions including renal damage, chronic kidney disease and cardiovascular disease. Source: Toxin and Toxin Target Database (T3DB)
  • Toxicity Summary: 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. Source: Hazardous Substances Data Bank (HSDB)
  • Toxicity Summary: 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).

  • Environmental Bioconcentration: An estimated BCF of 140 was calculated in fish for decaldehyde(SRC), using an estimated log Kow of 3.76(1) and a regression-derived equation(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is high(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: 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). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: 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). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: 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).
