Absorption is the movement of a chemical into a plant, animal or soil. This is an exposure route into your body. Absorption can be compared to a sponge used to soak up spilled water. Acute is the short-term effect which occurs when exposed to a chemical for a short time. An example of an acute effect would be a blast of steam on bare skin that causes burns.
Adsorption means to collect gas or liquid modules onto the surface of another material.
Rain that beads on the hood of a newly waxed car would be an analogy for adsorption. An example of a chronic condition would be sore feet from wearing tight shoes for a long time. Exposure Routes are one of four ways that hazards enter the body. Exposure routes can be compared to highways into your body, a distinct path that something can travel to reach a destination. Flammable Limits can be described as Lower and Upper Limits.
