Sensitivity Data CHLOROACETALDEHYDE PRESENTS A SERIOUS HAZARD FROM INHALATION OF ITS VAPOR, WHICH IS IRRITATING TO EYES, NOSE, & THROAT. VAPOR CONCN WHICH PRODUCE IRRITATION ARE READILY ATTAINABLE AT ROOM CONDITIONS.
Environmental Impact Chloroacetaldehyde may be released to the environment at processing sites, during transport, and from use as a fungicide. If released to moist soil, chloroacetaldehyde is expected to be highly mobile and susceptible to significant leaching. If released to dry soil, this compound is expected to volatilize fairly rapidly from soil surfaces. If released to water, volatilization should be an important, if not the dominant, removal mechanism (half-life from a model river - 42 hours). If released to the atmosphere, chloroacetaldehyde is expected to exist primarily in the vapor phase. Reaction with photochemically generated hydroxyl radicals is expected to be the dominant removal mechanism (half-life 1.7 days). This compound may be susceptible to removal from the atmosphere by wet deposition; however, any chloroacetaldehyde removed from the atmosphere by this mechanism has the potential to reenter the atmosphere by volatilization.
Environmental Fate TERRESTRIAL FATE: If released to moist soil, chloroacetaldehyde is expected to be highly mobile and susceptible to significant leaching. This compound is expected to volatilize fairly rapidly from dry soil surfaces. AQUATIC FATE: If released to water, volatilization is expected to be an important, if not the dominant, removal mechanism. The volatilization half-life from a model river has been estimated to be 42 hours. Chloroacetaldehyde is not expected to undergo chemical oxidation, bioaccumulate significantly in aquatic organisms, or adsorb significantly to suspended solids or sediments in water. ATMOSPHERIC FATE: Based on a vapor pressure of 100 mm Hg at 20 deg C, chloroacetaldehyde is expected to exist primarily in the vapor phase in the atmosphere(1,2,SRC). Reaction with photochemically generated hydroxyl radicals is expected to be the dominant removal mechanism (half-life 1.7 days). The relatively high water solubility of chloroacetaldehyde suggests that this compound would be susceptible to removal from the atmosphere by wet deposition; however, any chloroacetaldehyde removed from the atmosphere by this mechanism has the potential to reenter the atmosphere by volatilization.
