|Environmental Impact|| Resorcinol may be released to the environment in waste effluents associated with coal
gasification and conversion, coal-tar production, and shale oil processing and from the
combustion of wood and tobacco. If released to the atmosphere, resorcinol is expected to degrade
rapidly (estimated half-life of 1.9 hr) by reaction with photochemically produced hydroxyl
radicals. Night-time reaction with nitrate radicals may also contribute to its atmospheric
transformation. If released to soil or water, biodegradation is expected to be an important fate
process based on the results of a number of biological screening studies which have suggested that
resorcinol is readily biodegradable. By analogy to other phenol compounds, resorcinol may react
relatively rapidly in sunlit natural water with photochemically produced oxidants such as hydroxyl
and peroxy radicals. Resorcinol is expected to leach readily in soil; however, leaching may not be
important if concurrent biodegradation occurs at a rapid rate. Occupational exposure may occur
through dermal contact or inhalation at sites where the compound is produced or used as a
chemical intermediate, or at sites involved with coal conversion. Exposure to the general
population may occur through the inhalation of wood and tobacco smoke and through direct
dermal contact with topical medicinal products containing resorcinol.
|Environmental Fate|| TERRESTRIAL FATE: The major degradation process for resorcinol in soil is expected
to be biodegradation. A number of biological screening studies have found resorcinol to be readily
biodegradable. In a laboratory soil degradation study using a chernozem soil which had been
exposed to the coking industry, 500 ppm resorcinol was degraded in 2 days . Resorcinol is
expected to leach readily in soil; however, leaching may not be important if concurrent
biodegradation occurs at a rapid rate.
AQUATIC FATE: The major degradation processes for resorcinol in natural water may be
biodegradation and photooxidation. A number of biological screening studies have found
resorcinol to be readily biodegradable. By analogy to other phenol compounds, resorcinol may
react relatively rapidly in sunlit natural water with photochemically produced oxidants such as
hydroxyl and peroxy radicals; typical half-lives for hydroxyl radical and peroxy radical reaction
with phenol are on the order of 100 and 19.2 hours of sunlight, respectively . Aquatic
hydrolysis, volatilization, adsorption to sediments, and bioconcentration are not expected to be
ATMOSPHERIC FATE: Based upon an extrapolated vapor pressure of 3.84X10-4 mm Hg at 25
deg C(1,SRC), resorcinol can be expected to exist almost entirely in the gas-phase in the ambient
atmosphere(2,SRC). Gas-phase resorcinol is expected to degrade rapidly in air by reaction with
photochemically produced hydroxyl radicals; the half-life for this reaction in an average
atmosphere has been estimated to be 1.9 hr(3,SRC). Night-time reaction with nitrate radicals may
also contribute to the atmospheric transformation of resorcinol.
|Drinking Water Impact|| GROUND WATER: Resorcinol was found as a pollutant in filtered ground water at a
waste treatment plant .
SURFACE WATER: Resorcinol was found as a pollutant in filtered surface water at a waste
treatment plant .
EFFL: HAS ALSO BEEN FOUND IN EFFLUENTS RESULTING FROM PRODUCTION
OF COAL-TAR CHEM No concn given.
The concn of resorcinol in the condensate water from a coal gasification facility in Grand Forks,
ND ranged from not detected (no analytical detection limit reported) to 60 ppm between Jun
1980 and Apr 1982 . A resorcinol level of 1000 ppm was detected in wastewater from a
synthetic coal conversion process . Resorcinol has been found in wood smoke and cigarette
smoke and in effluents generated from the production of coal-tar chemicals .
