I-FLUORIDE EMANZI OKUPHUZA:
Ukubuyekezwa Kwezesayensi Kwamazinga EPA
ishicilelwe i-2006
Umbiko wamakhasi angama-400 obuyekeza lonke ulwazi kuze kube yileso sikhathi maqondana nemiphumela ye-fluoride emanzini okuphuza ezithweni, kwizicubu nakubantu abangabanjwa.
Lo mbiko wandulelwa yimibhalo eminingi ekhombisa ukungabi nalutho imiphumela ye-fluoride engenisiwe ku-IQ yezingane.
IZINGA LOKUPHUZA-AMANZI
Umgomo Wezinga Elikhulu Lokungcola
Ngokuya ngobufakazi obuhlangene ezindaweni ezihlukene zokuphela kwezempilo nokuvezwa okuphelele kwe
fluoride, ikomidi liphetha ngokuthi i-MCLG ye-EPA ka-4 mg / L kufanele yehliswe. Ukwehlisa
i-MCLG izovimbela izingane ekuthuthukiseni i-koqweqwe lwe-koqweqwe lwawo futhi izonciphisa
ukuqongelela impilo i-fluoride ibe ngamathambo iningi lekomidi eliphetha ngokuthi kungenzeka
ukubeka abantu engcupheni yokuqhekeka kwamathambo futhi mhlawumbe nohlaka lwamathambo, okuyi
ukukhathazeka okuthile ngabantu abancane abavame ukuqoqana ne-fluoride emathanjeni abo.
Ukwakha i-MCLG evikela ku-koqweqwe lwawo olunzima, isigaba sesibili somtholampilo
i-skeletal fluorosis, nokuqhekeka kwamathambo, i-EPA kufanele ibuyekeze ukuhlolwa kobungozi be-fluoride ukuze
faka imininingwane emisha engcupheni yezempilo nokulinganiselwa okungcono kokuchayeka okuphelele (umthombo ohlobene
umnikelo) wabantu ngabanye. I-EPA kufanele isebenzise izindlela zamanje zokulinganisa ubungozi,
ucubungula ukungcola okungenzeka kube lula, futhi ubeke ukungaqiniseki nokuhlukahluka.
