Just one correction to your comment: as far as I know, it is entirely FALSE that "chlorine can be absorbed through the skin". Rather there is evidence that some halogenated compounds -- which may, or may not be present in pools -- can be so absorbed.

But keep in mind that salt is a halogen compound, as is your pool liner, as are many other ubiquitous materials.
