Kaliforniya ayaa Talaadadii ku dhawaaqday inay ka fiirsanayso inay u baahan tahay soosaarayaasha taayirka inay daraasad ku sameeyaan siyaabaha looga takhalusi karo zinc alaabadooda sababtoo ah daraasaduhu waxay muujiyeen in macdanta loo isticmaalo in lagu xoojiyo caagga ay waxyeello u geysan karto marin-biyoodka.
Wakaaladdu waxay bayaan ku sheegtay in Waaxda Ilaalinta Walaxda Sumaynta ee Golaha Gobolka ay bilaabi doonto inay diyaariso "dokumentiyada farsamada ee la sii daayo guga" oo ay raadiso fikradaha dadweynaha iyo warshadaha ka hor inta aysan go'aansan in la sameeyo xeerar cusub iyo in kale.
Waxa werwerka leh ayaa ah in Zinc-ka ku jira taayirka taayirrada uu ku maydho biyo-mareennada biyaha roobka oo lagu rogo webiyada, harooyinka iyo durdurrada, taasoo waxyeello u geysata kalluunka iyo duurjoogta kale.
Ururka Tayada Biyaha Stormwater ee California (Ururka Tayada Stormwater ee California) ayaa waydiistay waaxda inay qaado talaabo ay ku darto taayirada zinc ku jira liiska mudnaanta wax soo saarka ee "Xeerarka Alaabada Macaamilka Badbaadada ah" ee gobolka.
Sida laga soo xigtay website-ka ururka, ururku wuxuu ka kooban yahay hay'ado federaali ah, dawlad-goboleed iyo kuwa maxaliga ah, degmooyinka dugsiyada, adeegyada biyaha, iyo in ka badan 180 magaalo iyo 23 gobol oo maamula biyaha wasakhda ah.
"Zinc waxay sun u tahay noolaha biyaha waxaana lagu ogaadey heerar sare oo biyo-mareenno badan," Meredith Williams, oo ah agaasimaha Waaxda Xakamaynta Walxaha Sunta, ayaa ku yiri hadal uu soo saaray."Hay'adda xakamaynta daadadka waxay bixisaa sabab adag oo lagu baranayo hababka xakamaynta."
Ururka Soosaarayaasha Taayirada Mareykanka ayaa sheegay in zinc oxide uu ka ciyaaro "door muhiim ah oo aan la bedeli karin" sameynta taayirrada culeyska qaadi kara oo si badbaado leh u dhigan kara.
"Wax-soo-saarayaashu waxay tijaabiyeen noocyo kala duwan oo oksijiin bir ah si ay u beddelaan ama u yareeyaan isticmaalka zinc, laakiin ma aysan helin beddel ammaan ah.Haddii aan zinc oxide la isticmaalin, taayirrada ma buuxin doonaan heerarka badbaadada federaalka."
Ururku waxa kale oo uu sheegay in liiska gobolka lagu daro taayir ka kooban zinc “ma gaadhi doono ujeedadii loogu talo galay” sababtoo ah taayirrada ayaa inta badan ka kooban wax ka yar 10% zinc deegaanka, halka ilaha kale ee zinc ay yihiin ilaa 75%.
Markii ururku ku booriyay "hab wada shaqayn, hab dhammaystiran" si loo xalliyo dhibaatadan, waxay tidhi: "Zinc si dabiici ah ayaa laga helaa deegaanka waxaana lagu daraa badeecooyin badan, oo ay ku jiraan birta galvanized, bacriminta, rinjiga, baytariyada, bireega iyo taayirada."
