Kazhinji, goridhe kuwanda kweSouth Atlantic uye pakati pePacific samples zvakafanana (~ 50 femtomol / L) asi zvishoma chokwadi. Mvura yeMediterranean yakadzika ine zvishoma kukwirira kwegoridhe (100<unk>150 femtomol / L) kunotsanangurwa neguruva rinoputika nemhepo uye / kana nzizi. Pa10 zvikamu pa quadrillion makungwa ePasi aizochengeta matani gumi nemashanu egoridhe. Iyi mibairo iri matatu yakaderera pane yakataurwa muzvinyorwa zvisati zvaitika muna 1988, zvichiratidza kusvibiswa nedata rekare. Mubvunzo: Iko kuwanda kwegoridhe kunoyerwa mumayuniti api?
