ABSTRACT
Ethyl methyl ether may be released to the environment as a result of its manufacture and use. It has been used as an anesthetic. If ethyl methyl ether is released to soil, it will be subject to volatilization. It will be expected to exhibit very high mobility in soil and, therefore, it may leach to ground water. It will not be expected to hydrolyze in soil. If ethyl methyl ether is released to water, it will not be expected to significantly adsorb to sediment or suspended particulate matter, bioconcentrate in aquatic organisms, hydrolyze, directly photolyze, or photooxidize via reaction with photochemically produced hydroxyl radicals in the water, based upon estimated physical-chemical properties or analogies to other structurally related aliphatic ethers. Many ethers are known to be resistant to biodegradation.
