A major pathway of induced health consequences occurs from spills or leaks of solvents, In particular chlorinated solvents, that get to the underlying soil. Because solvents quickly migrate considerable distances, the generation of common soil contamination just isn't unheard of; this is especially a health threat if aquifers are influenced.[41] Vapor intrusion can take place from sites with intensive subsurface solvent contamination.[forty two]
A solvent could be the element of a solution that is present in the best quantity. It's the material during which the solute is dissolved. Generally, a solvent can be a liquid.
