SECTION 4: First aid measures
Description of necessary first-aid measures
Fresh air, rest. Refer for medical attention.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Refer for medical attention .
Most important symptoms/effects, acute and delayed
Inhalation or ingestion causes headache, drowsiness, nausea, and blue color in lips, ears, and fingernails (cyanosis). Contact with eyes causes irritation. Can be absorbed through the intact skin to give same symptoms as for inhalation. (USCG, 1999)
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. Dinitrophenol and Related Compounds

Persistence and degradability
AEROBIC: More than 64 days were required to biodegrade 2-nitrophenol in an aqueous soil solution(1) however 2-nitrophenol was completely degraded in 7-14 days in a second soil inoculum(2). 2-Nitrophenol was mineralized 10% in a terrestrial ecosystem over the course of 10 days(3). 2-Nitrophenol, present at 100 mg/L, reached 0% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(4). A half-life of about 37 days was observed for 2-nitrophenol in a laboratory batch microcosm incubated with sediment and groundwater(5). 2-Nitrophenol was degraded over 80% in an aerobic groundwater/sediment microcosm from a landfill during a 60 day incubation period(6). First-order rate constants of 0.01/day to 0.05/day were determined for 2-nitrophenol in aerobic aquifer material(7), corresponding to half-lives of about 14-69 days(SRC).
Bioaccumulative potential
BCF values of <2.2 to 5 were measured for carp (Cyprinus carpio) exposed to 1 ppm of 2-nitrophenol over a 6 week incubation period(1); BCF values of <22 were measured for carp exposed to 0.1 ppm 2-nitrophenol over a 6 week incubation period(1). According to a classification scheme(2), these BCF values suggest bioconcentration in aquatic organisms is low.
Mobility in soil
The Koc of 2-nitrophenol in five reference European soils (pH 3.2-7.4) ranged from 32.1 to 265.7 with Koc generally decreasing with increasing pH(1); similar Koc values were determined for a second-generation set of five reference European soils(2). The Koc for 2-nitrophenol in Brookston clay loam was 114(3). In sorption studies using peat, 2-nitrophenol had measured Koc values of 85 (when 2-nitrophenol was in the neutral state) and 13 (when 2-nitrophenol existed as anionic species)(4). According to a classification scheme(5), a Koc range of 13 to 265 suggests that 2-nitrophenol is expected to have very high to moderate mobility in soil. The pKa of 2-nitropehnol is 7.23(6), indicating that this compound will exist partially 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(7).
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.
