| FIFRA-Anforderungen | As the federal pesticide law FIFRA directs, EPA is conducting a comprehensive review of older pesticides to consider their health and environmental effects and make decisions about their future use. Under this pesticide reregistration program, EPA examines health and safety data for pesticide active ingredients initially registered before November 1, 1984, and determines whether they are eligible for reregistration. In addition, all pesticides must meet the new safety standard of the Food Quality Protection Act of 1996. Pesticides for which EPA had not issued Registration Standards prior to the effective date of FIFRA, as amended in 1988, were divided into three lists based upon their potential for human exposure and other factors, with List B containing pesticides of greater concern and List D pesticides of less concern. Oleic acid is found on List D. Case No: 4083Pesticide type: insecticide, fungicide, herbicide, rodenticide, antimicrobialCase Status: RED Approved 09/92OPP has made a decision that some/all uses of the pesticide are eligible for reregistration, as reflected in a Reregistration Eligibility Decision (RED) document.Active ingredient (AI): Oleic acidAI Status: The active ingredient is no longer contained in any registered pesticide products ...

| Preventive Measures | SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.SRP: Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers. Contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning. |

| Umweltverhalten | TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 340,000 for the free acid(SRC), determined from a log Kow of 7.64(2) and a regression-derived equation(3), indicates that undissociated oleic acid is expected to be immobile in soil(SRC). The pKa of oleic acid is 5.02(4), indicating that this compound will exist almost entirely in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5). Volatilization of oleic acid from moist soil is not expected to be an important fate process because the acid is in the anion form and anions do not volatilize(SRC). Oleic acid is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 5.46X10-7 mm Hg(6). Biodegradation is expected to be an important fate process in soil based on half-lives of 0.2 and 0.66 days in screening tests(7,8).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 340,000 for the free acid(SRC), determined from a log Kow of 7.64(2) and a regression-derived equation(3), indicates that undissociated oleic acid is expected to adsorb to suspended solids and sediment(SRC). A pKa of 5.02(4) indicates oleic acid will exist almost entirely in the anion form at pH values of 5 to 9 and therefore volatilization from water surfaces is not expected to be an important fate process(5). According to a classification scheme(6), an estimated BCF of 10(SRC), from its log Kow(2) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). A 47 and 52 theoretical %BOD for oleic acid measured over a period of 5 days using sewage inoculum(8) and a biodegradation half-life of 0.66 days using activated sludge inocula(9) suggest that biodegradation may be an important environmental fate process in aquatic ecosystems(SRC).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), oleic acid, which has a vapor pressure of 5.46X10-7 mm Hg at 25 °C(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase oleic acid is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC)the half-life for cis-oleic acid and trans-oleic acid reactions in air are estimated to be 5.1 and 4.6 hours(SRC), calculated from rate constants of 7.6X10-11 and 8.3X10-11cu cm/molecule-sec at 25 °C(SRC) that were derived using a structure estimation method(3). Vapor-phase oleic acid is also degraded in the atmosphere by reaction with ozone(SRC)the half-life for cis-oleic acid and trans-oleic acid reactions in air are estimated to be 2.1 and 1.4 hours(SRC), respectively, calculated from rate constants of 1.3X10-16 and 2.0X10-16 cu cm/molecule-sec at 25 °C(SRC) that were derived using a structure estimation method(3). Particulate-phase oleic acid may be removed from the air by wet or dry deposition(SRC). Oleic acid does not contain chromophores that absorb at wavelengths >290 nm and therefore is not expected to be susceptible to direct photolysis by sunlight(4). |

| Ökotoxizitätsauszüge | /AQUATIC SPECIES/ The toxicities of chemicals found in bleached kraft pulp mill effluent were assessed using a sea urchin sperm toxicity test. Sperm of the purple sea urchin, Strongylocentrotus purpuratus, were preincubated with 12 individual compounds, including resin acids, unsaturated fatty acids, their chlorinated derivatives and chlorinated guaiacols. Sperm were then coincubated with eggs and inhibition of fertilization and the effects on sperm motility were assessed. Resin acids, which are highly toxic to juvenile salmonids in freshwater, were less toxic in seawater (EC50s ranging from 2 to more than 20 mg/L). Unsaturated linoleic and linolenic fatty acids inhibited fertilization at lower concentrations (EC50s of 0.28 to 1.07 mg/L) than resin acids, although they are less toxic than resin acids to freshwater fishes. Oleic acid was not significantly toxic up to 75 mg/L. Chlorinated derivatives showed increasing toxicity with increasing chlorination, and chlorinated resin acids were more toxic than their unchlorinated parent compound. Dichlorostearic acid was the most toxic compound tested, with an EC50 of 0.057 mg/L. All compounds except fatty acids inhibited sperm motility. These results indicate that some of the major constituents of pulp mill effluent exhibit very different levels of toxicity in seawater using a sea urchin sperm cell toxicity test as compared to freshwater bioassays using juvenile salmonids. In addition, mechanisms of action on the sperm appear to differ among the compounds. Accurate quantification of the compounds in effluent as well as the potential effect of the effluent on other marine organisms remains to be determined. |
