no data available
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 if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on the 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. Poisons A and B

Possibility of hazardous reactions
Organophosphates, such as DIBUTYLPHENYL PHOSPHATE, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.

Persistence and degradability
AEROBIC: Dibutyl phenyl phosphate, present at 19.7 ppm, reached 61.5 and 84.4% of theoretical CO2 evolution in a CO2-Evolution screening study using acclimated seed (14 day acclimation period) over an incubation period of 7 and 28 days, respectively. In similar experiments, dibutyl phenyl phosphate at initial concentration of 20.6 ppm, reached 11.1, 75.6, and 84.5% of theoretical CO2 evolution in incubation periods of 7, 28, and 48 days, respectively. Dibutyl phenyl phosphate biodegraded 52 and 95% at an addition rate of 13 and 3 mg/L-24 hrs, respectively, in semicontinuous activated sludge (SCAS) tests run at 4 and 21 weeks, respectively. At an initial concentration of 1 ppm, dibutyl phenyl phosphate had a half-life of about 3.5 days in a river die-away test(1).
Bioaccumulative potential
An estimated BCF of 46 was calculated in fish for dibutyl phenyl phosphate(SRC), using a log Kow of 4.27(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC).
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of dibutyl phenyl phosphate can be estimated to be 930(SRC). According to a classification scheme(2), this estimated Koc value suggests that dibutyl phenyl phosphate is expected to have low mobility in soil.
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.
