Gypsum will be purified

If well treated (removed by its toxic, radiocative and rare earths and heavy metals), gypsum will be suitable to be used inside homes, in wall and ceilings...
If dispersed into the sea, nobody will know (not before decades long studies) where (into tissues of marine plants and animals) noxious metals will acumulate!
