4.2 Most important symptoms/effects, acute and delayedno data available
4.3 Indication of immediate medical attention and special treatment needed, if necessary/SRP:/ 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/

AEROBIC: The biodegradability of alpha-ionone is expected to be analogous to beta-ionone(SRC). Using the OECD 301F method (manometric respirometry) with an activated sludge inoculum, beta-ionone, at 50 mg/L, reached 79% of its theoretical BOD in 28 days which classified the compound as readily biodegradable(1). beta-Ionone was also classified as readily biodegradable by the results of a CO2-evolution test where beta-ionone, at 10 mg/L, achieved 46% and 73% CO2 evolution after 7 and 28 days respectively(1). Another respirometry study reported 80% biodegradation of beta-ionone at 100 mg/L(2). In a spiked river water die-away test using water from the Murrumbidgee River, beta-ionone, at 6.28 ug/L, was degraded about 95% after 20 hours of incubation(1). Results of a modified MITI test (OECD 301C) reported 50% degradation of beta-ionone after 28 days (consistent with inherent biodegradability), but concentrations or inoculum were not reported(1).
12.3 Bioaccumulative potentialAn estimated BCF of 161 was calculated in fish for alpha-ionone(SRC), using a log Kow of 3.85(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is high(SRC), provided the compound is not metabolized by the organism(SRC).
12.4 Mobility in soilUsing a structure estimation method based on molecular connectivity indices(1), the Koc of alpha-ionone can be estimated to be 670(SRC). According to a classification scheme(2), this estimated Koc value suggests that alpha-ionone is expected to have low mobility in soil.
12.5 Other adverse effectsno data available
13.Disposal considerations 13.1 Disposal methods ProductThe 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 packagingContainers 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.
