The contaminants are stored in pores within the material, so they shouldn't come into contact with the wearer. In fact, the only way of releasing them is to heat the Sponge to at least 1,000 ºC (1,832 ºF). This can be done up to 20 times before the inserts start losing their absorbency.
Some of these materials have been incorporated in school uniforms, as well as the clothing of fishermen in Makoko.
