METHYL ETHYL KETONE 41-2<br />
PERSISTENCE<br />
IN THE SOIL-<br />
WATER SYSTEM<br />
J<br />
Methyl ethyl ketone is expected to migrate in the<br />
soil/ground-water system with very little retardation.<br />
Volatilization from near-surface soils may occur: however,<br />
vapor concentrations in soil are expected to be very low<br />
whenever water is present. Biodegradation of methyl ethyl<br />
ketone has been demonstrated <strong>and</strong> persistence in environments<br />
with active microbial populations is not expected.<br />
The primary pathway of concern from a soil/ground-water<br />
PATHWAYS system is the migration of methyl ethyl ketone to ground-<br />
OF water drinking water supplies. Inhalation may be important<br />
EXPOSURE in some situations. Bioaccumulation of methyl ethyl ketone<br />
is not likely to be an important exposure pathway.<br />

<strong>and</strong> Svmotoms of Short w term Hmosure (131 .<br />
Eye, nose <strong>and</strong> throat irritation are usually the first<br />
symptoms to appear in methyl ethyl ketone exposure.' At high<br />
concentrations, CNS depression <strong>and</strong> narcosis along with congestion<br />
of the lungs, liver <strong>and</strong> kidneys are observed.<br />

of 200 - 1000 ppm: chemical cartridge respirator<br />
with organic vapor cartridge <strong>and</strong> full facepiece l 1000 -<br />

air respirator or self-contained breathing apparatus<br />
with full facepiece l Butyl, natural rubber, neoprene, nitrile,<br />
PE, WA or WC gloves, apron <strong>and</strong> boots to prevent repeated<br />
or prolonged skin contact with the liquid l Chemical<br />
goggles if there is probability of eye contact.<br />
m: Give large quantities of salt water <strong>and</strong> induce<br />
EMERGENCY vomiting if victim is conscious. Get medical attention<br />
FIRST AID l -ation: Move victim to fresh air immediately <strong>and</strong> per-<br />
TREATMENT form artifical respiration if necessary l u: Remove con-<br />
(54) taminated clothing. Wash skin with soap <strong>and</strong> water l Eya:<br />
Irrigate with large amounts of water immediately.<br />
