It can also be absorbed through skin contact. It does not remain in the body due to its breakdown and removal in expired air or urine. Methanol evaporates when exposed to air. It dissolves completely when mixed with water. Most direct releases of methanol to the environment are to air.
Methanol also evaporates from water and soil exposed to air.
Once in air, it breaks down to other chemicals. Microorganisms that live in water and in soil can also break down methanol. Because it is a liquid that does not bind well to soil, methanol that makes its way into the ground can move through the ground and enter groundwater. Plants and animals are not likely to store methanol. Effects of methanol on human health and the environment depend on how much methanol is present and the length and frequency of exposure.
