Ibikoresho bigezweho byo gusesengura birashobora kumenya ibisigisigi kuriibice kuri miliyari (ppb)urwego. Amazi ya chromatografiya-rusange ya sprometrike (LC-MS) agaragaza imbaraga zingana no gushonga ingano imwe yumunyu muri pisine nini yo koga. Iyi sensitivite isobanura "ibishoboka" ibisigisigi bigenda biba imbonekarimwe. Mu 2024, ibisigazwa by’udukoko twangiza udukoko byagaragaye muri 68% by’ibicuruzwa by’ubuhinzi byatoranijwe, nyamara 1,4% byonyine byarenze imipaka - byerekana ko"gutahura birasanzwe, kurenga ibipimo ni gake."
