4.2 Most important symptoms/effects, acute and delayed

SYMPTOMS: Symptoms of overexposure to this compound include nausea, vomiting, cyanosis from methemoglobinemia, injury to the liver, kidneys, central nervous system and heart, circulatory collapse, drowsiness, confusion, liver tenderness, low blood pressure, cardiac arrhythmias, jaundice, acute renal failure, death due to liver necrosis, metabolic acidosis, hepatic damage and cirrhosis. Other symptoms include changes in exocrine pancreas, diarrhea, irritability, somnolence, general anesthesia, fever and hepatitis. Diaphoresis and general malaise may occur. Exposure may lead to hematological reactions and, occasionally, skin rashes and other allergic reactions. The rash is usually erythematous or urticarial, but sometimes it is more serious and may be accompanied by drug fever and mucosal lesions. Exposure to large amounts may lead to pallor, anorexia, abdominal pain, abnormalities of glucose metabolism and hepatic encephalopathy. It may also lead to epigastric pain, sweating, paresthesias of distal extremities, muscular aching, weakness, dizziness, central nervous system depression (rare), pain in the upper right quadrant, enlarged liver, oliguria, anuria, coagulation defects and myocardiopathy characterized by ST segment abnormalities, T-wave flattening and pericarditis. This compound can cause purpura, generalized bleeding and hypoglycemia. It can also cause neutropenia, pancytopenia, leukopenia, thrombocytopenia and nephrotoxicity. Other symptoms may include wheezing, general discomfort, blood changes including many anemias (aplastic anemia), central nervous system stimulation, swollen tongue, rapid pulse, skin eruptions, chills, excitement, delirium, vascular collapse and convulsions. Irritation of the skin, eyes, mucous membranes and upper respiratory tract may occur. ACUTE/CHRONIC HAZARDS: This compound may be harmful by ingestion and inhalation. It may cause irritation of the skin, eyes, mucous membranes and upper respiratory tract. When heated to decomposition it emits toxic fumes of carbon monoxide, carbon dioxide and nitrogen oxides.

4.3 Indication of immediate medical attention and special treatment needed, if necessary

Emergency and supportive measures. Spontaneous vomiting may delay the oral administration of antidote or charcoal and can be treated with metoclopramide or a serotonin receptor antagonist such as ondansetron. Provide general supportive care for hepatic or renal failure if it occurs. Emergency liver transplant may be necessary for fulminant hepatic failure. Encephalopathy, metabolic acidosis, hypoglycemia, and a progressive rise in the prothrombin time are indications of severe liver injury.

• Toxicity to algae: no data available
• Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: Acetaminophen has been categorized as readily biodegradable following acclimation(1). A half-life of 20 days has been reported for acetaminophen using an activated sludge inoculum(2). Half-lives of 40 and 17 days were observed when using activated sludge inoculums acclimated to phenol(3) and cresol(4), respectively. Acetaminophen reached 94% of its theoretical BOD in 6 days using an activated sludge inoculum and the Zahn-Wellens test(5). The rate constants for non-adapted, phenol-adapted, and cresol-adapted activated sludge (sludge concentrations of 500, 10, and 50 mg/L) were 0.141X10-2, 0.713X10-3, and 0.215X10-2 1/hr, respectively(6); half-lives are 21, 40, and 13 days, respectively(SRC). Acetaminophen, present at 100 ug/L, exhibited biodegradation rates of 0.014/hr and 0.00051/hr in 5 days using Tamlya and Tsumeta River water (Japan), respectively, and the OECD 301-A river die-away test. The corresponding half-lives are 50 and 1400 hours, respectively(7).

12.3 Bioaccumulative potential

An estimated BCF of 3 was calculated in fish for acetaminophen(SRC), using a log Kow of 0.46(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

12.4 Mobility in soil

The Koc of acetaminophen is estimated as 21(SRC), using a log Kow of 0.46(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that acetaminophen is expected to have very high mobility in soil. The pKa of acetaminophen is 9.38(4), indicating that this compound will exist partially in the anion form in the environment and anions generally adsorb less strongly to soils containing organic carbon and clay than their neutral counterparts(5). However, low mobilty was observed in soils with a high organic content. Kd values of 46 and 36 in clayey silt and silty sand, respectively, have been reported when the test compound was applied in standard dilution(6). Kd values of 45 and 41 in clayey silt and silty sand, respectively, have been reported when acetaminophen was applied as a test sludge; the average Kd value of 42 indicated low mobility(6). Acetaminophen, present at <0.009 ug/L, was not detected in leachate water (treated effluent from a muncipal wastewater treatment facility) following a 23-day soil column leaching experiment using Mohall-Laveen sandy loam (detection limit = 0.009 ug/L)(7).

12.5 Other adverse effects

13.Disposal considerations

13.1 Disposal methods

Product

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.

Contaminated packaging

Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
