Indication of immediate medical attention and special treatment needed, if necessary
Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. Organic acids and related compounds

Persistence and degradability
AEROBIC: During a 29-day incubation period of freshwater from the Tama River, Japan, the concentration of palmitic acid decreased from 536 to 3.7 ug/L, suggesting a half-life of approximately 0.50 days(1). Palmitic acid has been listed as an organic chemical normally easily biodegradable by biological sewage treatment, no data provided(2). Palmitic acid, present at unknown concns, reached 2% of its theoretical BOD in 5 days using a sewage inoculum(3). Palmitic acid, present at unknown concns, reached 37.2% of its theoretical BOD in 5 days using a sewage inoculum(4). Using the Warburg test method, palmitic acid, present at 500 ppm, reached 2.5% of its theoretical BOD in 1 day using activated sludge solids at a concentration of 2,500 mg/L(5). Using the Warburg test method, the biodegradation of palmitic acid in the presence of an activated sludge inoculum at 25 deg C was determined to have a half-life of 3.75 days(6). Palmitic acid, at a concn of 0.05 ppm in the presence of 50 ug/L activated sludge, produced 37.8% carbon dioxide in 5 days(7).
Bioaccumulative potential
The bioaccumulation factor of palmitic acid in golden ide fish (Leuciscus idus melanotus), calculated as the concn of chemical in fish (ug/g) divided by the medium concn of chemical in water (ug/g), was determined to be 60 after 3 days(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC). The bioaccumulation factor of palmitic acid in algae (Chlorella fusca), calculated as the concn of chemical in algae (ug/g) divided by the final concn of chemical in water (ug/g), was determined to be 8,400 after 1 day(1).
Mobility in soil
The Koc of undissociated palmitic acid is estimated as 189,000(SRC), using a log Kow of 7.17(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that undissociated palmitic acid is expected to be immobile in soil. The estimated pKa of palmitic acid is 4.7(4), indicating that this compound will exist almost entirely in the 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).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
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.
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.
