Indication of any immediate medical attention and special treatment needed
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. Esters and related compounds

Toxicity
- Toxicity to fish: LC50 - Menidia beryllina - 574 mg/L - 96 h.
- Toxicity to daphnia and other aquatic invertebrates: LC50 - Americamysis bahia (previous name: Mysidopsis bahia) - 14 mg/L - 96 h.
- Toxicity to algae: EC50 - Pseudokirchneriella subcapitata (previous names: Raphidocelis subcapitata, Selenastrum capricornutum) - 230 mg/L - 72 h.

Persistence and degradability
AEROBIC: No biodegradation of tert-amyl methyl ether, present at 3,000 ug/L, was observed when incubated in soils with previous exposure to methyl tert-butyl ether(1). A rate of -40 mg/L/day was reported using acclimated activated sludge. A rate of 69 mg/L per day (0.09 g/g dry weight/day) was removed using upflow anoxic fixed bed reactors, a removal efficiency of >98%(2). tert-Amyl methyl ether did not pass the ready biodegradability test of 60% in 28 days using the Closed Bottle test(3).
Bioaccumulative potential
An estimated BCF of 5 was calculated in fish for tert-amyl methyl ether(SRC), using a log Kow of 1.55(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
The Koc of tert-amyl methyl ether has been reported to range from 19 to 160(1,2). According to a classification scheme(3), these Koc values suggest that tert-amyl methyl ether is expected to have very high to moderate mobility in soil. Using a model system simulating horizontal ground water flow in the saturated zone, consisting of only soil and water phases (an unconfined sand aquifer was selected as an example case), a Koc of 60 was calculated(4).
Other adverse effects
no data available
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.
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.
