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/

12.2 Persistence and degradability
AEROBIC: Using OECD Guide-line 302B (Inherent biodegradability: Modified Zahn-Wellens Test) and a non-adapted activated sludge inoculum, dimethyl hexahydroterephthalate reached 98% after 14-days(1). Dimethyl hexahydroterephthalate, present at 52.3 mg/L, reached 82% of its theoretical BOD in 4 weeks using a non-adapted activated sludge inoculum(1). Using OECD Guide-line 301B (Ready biodegradation using the CO2 evolution test, Modified Sturm), dimethyl hexahydroterephthalate reached 81% and 79% degradation at 10 mg/L and 20 mg/L concentrations, respectively, over a 35-day incubation period(2); time for 10% degradation was 11 days(2).
12.3 Bioaccumulative potential
An estimated BCF of 11 was calculated in fish for dimethyl hexahydroterephthalate(SRC), using an estimated log Kow of 2.11(1) and a regression-derived equation(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
12.4 Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of dimethyl hexahydroterephthalate can be estimated to be 31(SRC). According to a classification scheme(2), this estimated Koc value suggests that dimethyl hexahydroterephthalate is expected to have very high mobility in soil.
12.5 Other adverse effects
no data available
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.
