Lub Yim Hli 31, Palu, Biologist Kws Kho Mob Aiyen Tjoa ntawm University of Central Sulawesi qhia cov txiaj ntsig ntawm nws kev tshawb fawb txog cov paj nickel ntawm Sol Sol Nickel Mine nyob rau sab qab teb Sulawesi xeev. Nickel paj yog hyperaccumulators. Tus nqi ntawm cov hlau hnyav uas tuaj yeem nqus cov npib tsib xee thiab lwm cov hlau hnyav yog ntau dua 10 zaug ntau dua li ntawm cov nroj tsuag zoo tib yam. Feem ntau, txhua kab ntawm nplooj muaj 1000 micrograms ntawm npib tsib xee. Nws tuaj yeem hais tias muaj cov xim nickel hauv cov me nyuam thiab yuav tsum muaj cov npib tsib xee.
Dr. Cai tau hais tias qhov tshwm sim ntawm cov npib tsib xee paj tau pom hauv xyoo 1970 los ntawm Antony van der Ent, Ph.D. ntawm Biology ntawm University of Queensland, Australia. Muaj ntau yam ntawm cov xim npib tsib xee, ntawm cov uas yog" Sarcotheca Nambica" thiab" Knema Matanensis" ;, uas tau pom tias muaj 1,000 daim duab nplooj. Txhawm rau 5000 micrograms ntawm npib tsib xee.
Dr. Tsai tau hais ntxiv tias raws li Dr. Anthony txoj kev tshawb fawb, yog tias peb tuaj yeem cog tau cov npib tsib xee paj loj uas tuaj yeem nqus tau 10,000 micrograms ib gram ntawm nplooj, peb tuaj yeem tsim cov roj nickel cog thiab sau cov npib tsib xee hauv qhov chaw zoo. 120 kg ntawm npib tsib xee tsim tawm
