SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational harm/injury/toxicity or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal and plant life; and conformance with environmental and public health regulations.

SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a permitted wastewater treatment facility is acceptable only after review by the governing authority and assurance that "pass through" violations will not occur. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must be evaluated in accordance with EPA 40 CFR Part 261, specifically Subpart B, in order to determine the appropriate local, state and federal requirements for disposal.

Burn in a chemical incinerator equipped with an afterburner and scrubber but exert extra care in igniting as this material is highly flammable. Offer surplus and non-recyclable solutions to a licensed disposal company. Contact a licensed professional waste disposal service to dispose of this material. Contaminated packaging: dispose of as unused product.

Acetic acid was qualitatively detected in 2 of 12 human milk samples collected from volunteers in four US cities(1). Acetic acid at 19.9 mg/day was measured from non-specified human emissions(2). Humans exude <90mg/day of volatile fatty acids in exhaled breath and perspiration, 80% of which is acetic acid(3); in a confined environment, as much as 15-20 mg/cu m can accumulate and such concentrations can become serious in submarines or space capsules(3).

Lead poisoning is usually treated with chelation therapy using DMSA, EDTA, or dimercaprol. (L21)

In cases of skin or eye exposure, the area should be flushed with water and burns covered with dry, sterile dressings after decontamination. If ingested, rinse mouth and administer 5 mL/kg up to 200 mL of water for dilution. Watch for signs of respiratory insufficiency and assist respiration if necessary. (A569)

Pain increases the rate, frequency, or intensity of some behaviors (eg, withdrawal responses) and suppresses other behaviors (eg, feeding). /The study is/ developing assays to test analgesic drug candidates using measurements of pain-suppressed rather than pain-elicited behaviors. Such assays may model important aspects of clinical pain and provide a means for distinguishing true analgesics from drugs that produce motor impairment. The present study compared effects of the mu opioid analgesic morphine and the nonanalgesic neuroleptic haloperidol on intraperitoneal acetic acid-induced writhing (a pain-elicited behavior) and suppression of feeding behavior (a pain-suppressed behavior). In feeding studies, C57BL/6J mice were given access to a dish containing 8 mL Ensure (trade mark) liquid food (0-100% in water) during daily sessions (7.5-120 min). Levels of consumption were dependent on both Ensure concentration and session duration. Intraperitoneal injection of acetic acid (0.10-0.56%) produced a time- and concentration-dependent decrease in Ensure consumption. Morphine (1 mg/kg) prevented both acid-induced writhing and acid-induced suppression of feeding, whereas the dopamine antagonist haloperidol inhibited writhing without preventing acid-induced suppression of feeding. The effects of morphine were time-dependent, selective for acid-suppressed feeding, and naltrexone-reversible. These results suggest that assays of pain-suppressed behaviors may complement assays of pain-elicited behaviors in preclinical studies of candidate analgesics...

Amylin is a member of calcitonin or calcitonin gene-related peptide (CGRP) family. Immunohistochemical study revealed a dense network of amylin-immunoreactive (irAMY) cell processes in the superficial dorsal horn of the mice. Numerous dorsal root ganglion (DRG) and trigeminal ganglion cells expressed moderate to strong irAMY. Reverse transcriptase-polymerase chain reaction (RT-PCR) revealed amylin receptor mRNA in the mouse spinal cord, brain stem, cortex, hypothalamus and hippocampus. The nociceptive or antinociceptive effects of amylin were evaluated in the acetic acid-induced writhing test. Amylin (0.1, 0.5 and 1 mg/kg, intraperitoneally (i.p.) or 1-10 microg, intrathecally (i.t.)) reduced the number of writhes in a dose-dependent manner. Pretreatment of the mice with the amylin receptor antagonist salmon calcitonin (8-32), either by i.p. or i.t., antagonized the effect of amylin on acetic acid-induced writhing test. Locomotor activity was not significantly modified by amylin injected either i.p. (0.01-1 mg/kg) or i.t. (1-10 microg). Measurement of c-fos mRNA by RT-PCR or proteins by Western blot showed that the levels were upregulated in the spinal cord of mice injected with acetic acid and the increase was attenuated by pretreatment with amylin (10 microg, i.t.). Collectively, /these/ result demonstrates that irAMY is expressed in DRG neurons with their cell processes projecting to the superficial layers of the dorsal horn, and that the peptide by interacting with amylin receptors in the spinal cord may be antinociceptive.

INTRODUCTION: Increased free-radical production, decreased antioxidant capacity, and excessive inflammation are well-known features in the pathogenesis of inflammatory bowel disease. Melatonin is a powerful antioxidant and a scavenger of hydroxyl radicals. Melatonin has also been shown to have anti-inflammatory activities in tissues. /This/ study objective is to investigate the effects of melatonin on tissue inflammatory activities using an ulcerative colitis (UC) model induced by acetic acid (AA) in rats. METHODS: Wistar rats (n = 32) were divided into four groups. AA-induced colitis was performed in two of the groups, while the other two groups were injected with saline intrarectally. One of the AA-induced colitis groups and one of the control groups were administered 100 mg/kg/day melatonin intraperitoneally, and the pair groups were given saline. After 4 days, colonic changes were evaluated biochemically by measuring proinflammatory cytokines [tumor necrosis factor (TNF)-alpha, interleukin (IL)-1beta, and IL-6], myeloperoxidase (MPO), malondialdehyde (MDA), glutathione (GSH), and superoxide dismutase (SOD) levels in tissue homogenates and by histopathological examination. RESULTS: AA caused colonic mucosal injury, whereas melatonin suppressed these changes in the AA-induced colitis group (P < 0.001). AA administration resulted in increased TNF-alpha, IL-1beta, IL-6, MPO, and MDA levels, and decreased GSH and SOD levels, whereas melatonin administration reversed these effects (all P < 0.001). CONCLUSIONS: The present study proposes that melatonin has a dual action as an effective anti-inflammatory and an antioxidant, and may be a hopeful therapeutic agent for UC.

In the present study, the effect of chronic oral administration of curcumin in the presence or absence of morphine and noloxone was investigated on the visceral nociception induced by acetic acid in rats. Intraperitoneal injection of acetic acid (1 mL, 2%) produced contractions in the abdominal musculature (writhes). The latency time to the beginning of the first writhe was measured and the total number of writhes in the 1 hr after acetic acid injection was counted. The latency time to the beginning of the first writhe was significantly (p < 0.05) increased and the number of writhes was significantly (p < 0.05) decreased by curcumin (20 and 40 mg/kg body weight). The same results were obtained after subcutaneous injection of morphine (1 mg/kg b.wt.). Naloxone at the dose of 1 mg/kg body weight had no effect on pain intensity. Curcumin significantly (p < 0.05) enhanced the effect of morphine on the visceral pain responses, however did not reverse the effect of naloxone. Present data suggest that in the acetic acid-induced visceral nociception of rats, curcumin may produce an antinociceptive effect and the endogenous analgesic opioid system is involved in the curcumin-induced antinociception.

Nine out bred white male rats weighing approximately 100 g were used in /this/ study. Rats were given either N-nitrosarcosin ethyl ester (NSEE) alone, NSEE with the acetic acid solution, or the acetic acid solution alone. doses (0.5 mL of 3% water solution of acetic acid (about 60 mg/kg bw/treatment) were given by intubation into the esophagus 3 times per week. Animals were killed by ether inhalation after 8 months of experiments and autopsied. As expected, rats treated with the carcinogen NSEE had high incidences of pre-neoplastic lesions of the esophagus and forestomach, as well as benign tumors, carcinomas and squamous cell cancer. Prolonged administration of acetic acid in combination with NSEE resulted in an increase in the number of benign and malignant tumors and carcinomas in the esophagus. Prolonged administration of acetic acid alone did not induce tumors. All nine of these rats, however, did experience hyperplasia in the esophagus and forestomach.

Lead is a neurotoxin and has been known to cause brain damage and reduced cognitive capacity, especially in children. Lead exposure can result in nephropathy, as well as blood disorders such as high blood pressure and anemia. Lead also exhibits reproductive toxicity and can results in miscarriages and reduced sperm production. (L21)

Concentrated acetic acid is corrosive and can cause skin burns, permanent eye damage, and irritation to the mucous membranes. Ingestion can cause severe damage to the digestive system and a potentially lethal change in the acidity of the blood. (L1885)

TERRESTRIAL FATE: Based on a classification scheme(1), an experimentally derived Koc value of 1.0(2,3), indicates that acetic acid is expected to have very high mobility in soil(SRC). No detectable sorption was measured for acetic acid using the OECD Guideline 106 method in three different soils(4). The pKa of acetic acid is 4.76(5), indicating that this compound will exist predominantly 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(6). Volatilization of acetic acid from moist soil surfaces is not expected to be an important fate process(SRC) given a Henry's Law constant of 1.43X10-7 atm-cu m/mole(7). Acetic acid is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 15.7 mm Hg at 25 °C(8). Using a modified Organization of Economic Cooperation and Development (OECD) protocol, 75% degradation was reported in 14 days using garden soil as an inoculum(9), indicating that biodegradation is an important environmental fate process in soil(SRC).

AQUATIC FATE: Based on a classification scheme(1), a Koc value of 1.0(2,3), indicates that acetic acid is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(4) based upon a Henry's Law constant of 1.43X10-7 atm-cu m/mole(5). The pKa of acetic acid is 4.76(6), indicating that this compound will exist predominantly in anion form at an environmental pH range of 5-9. According to a classification scheme(7), an estimated BCF of 3(SRC), from its log Kow of -0.71(8) and a regression-derived equation(9), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Hydrolysis is not expected to be an important environmental fate process(SRC) since this compound lacks functional groups that hydrolyze under environmental conditions(4). Utilizing the Japanese MITI test, a 74% of theoretical BOD in 2 weeks using activated sludge(10) indicates that biodegradation is an important environmenal fate process in water(SRC).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), acetic acid, which has a vapor pressure of 15.7 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. The pure compound is a solid below 68 °F(3). Particulate-phase acetic acid will be removed from the atmosphere by wet and dry deposition. Vapor-phase acetic acid 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 22 days(SRC), calculated from its measured rate constant of 7.4X10-13 cu cm/molecule-sec at 25 °C(4). Particulate-phase acetic acid will be removed from the atmosphere by wet and dry deposition. Acetic acid does not absorb light with wavelengths >290 nm(5) and, therefore, is not expected to be susceptible to direct photolysis by sunlight(SRC). Acetic acid occurs in rainwater, cloud water and fog(6-8) and can be removed from the atmosphere by wet deposition(SRC).

Acetic acid was identified as the major volatile constituent of commercial brown sugars(1); concentrations ranging from 31-827 ppm were detected in 26 brown sugars collected worldwide(1). The source of the acetic acid was found to be bacterial action in recycled sweet waters containing low levels of sucrose(1). Acetic acid was qualitatively detected as a volatile component of fried bacon, smoked pork, baked potatoes, soy sauce, roasted filbert nuts and frankfurters(2-6). Mean acetic acid concentrations of 39.6-116.6 were detected in several honeydew honey extracts(7).

Acetic acid was measured as a volatile compound in popped popcorn at a concentration of 4000 ug/kg(1), and in the extract of edible Korean chamchwi(2), cured pork(3), and volatiles from boiled short-necked clams, clams, and corbicula(4) at unreported concentrations. Volatile compounds from Bisbee Delicious apples included acetic acid present at concentrations from 25.6 to 3505.0 picoliter/kg-hr depending on the date of harvest(5). Acetic acid was reported in 7 different wines, ciders, and dessert wines and brandies from Germany at concentrations from 80 to 363 mg/L(6).

Twenty-two acids in ground roast coffees and instant coffees were determined by GLC (gas liquid chromatography) of their silyl derivatives (after preseparation by gel electrophoresis or isotachophoresis). The contribution to the total acidity (which was estimated by titration to pH 8 after cation exchange of the coffee solutions) was calculated for each individual acid. The acids contribute 67% (roast coffee) and 72% (instant coffee) to the total acidity. Citric acid (12.2% in roast coffee/10.7% in instant coffee), acetic acid (11.2%/8.8%) and the high MW acids (8%/9%) contribute to the total acidity.
