Sei Kutungamira-Isina, UKCA-Yakasimbiswa Brass Tee Fittings Matter
Utano Njodzi dzeMutobvu mumvura Inonwa
Kusvibiswa kwemutobvu mumvura yekunwa kunopa njodzi huru pautano, kunyanya kumapoka anotambura akaita sevana nevakadzi vane pamuviri. Ongororo dzesainzi dzakaratidza kuti kunyangwe mwero wakaderera wekuratidzwa nemutobvu unogona kukonzera kukuvadza kukuru.
- Vana vakafumurwa kutungamira vanogona kuve nekukanganiswa kwetsinga nekuziva, kusanganisira kuderedzwa IQ, kushomeka kwekutarisa, kuremara pakudzidza, uye matambudziko ehunhu.
- Vanhu vakuru vanotarisana nenjodzi dzekuwedzera hypertension, kukuvara kweitsvo, chirwere chemoyo, uye nyaya dzekubereka.
- Vakadzi vane pamuviri vakazarurwa nemvura ine mutobvu vane mikana mikuru yekupfupfudzika, kusununguka nguva isati yakwana, uye kusakura zvakanaka muvana vavo.
- Kusagadzikana kwenguva refu, kunyangwe pakudzika kwakadzika, kunogona kukonzera hutano hwenguva refu kune ese mazera.
Sangano reWorld Health Organisation neUS Environmental Protection Agency vakaisa mwero wakanyanya unobvumidzwa unotungamira mumvura yekunwa (0.01 mg/L uye 0.015 mg/L, zvichiteerana) nekuda kwenjodzi idzi. Nzvero, dzakadai seyakaitwa muHamburg, Germany, dzakawana kuwirirana kwakananga pakati pomutobvu mumvura yepombi nemwero yakakwirira yomutobvu weropa. Kupindira kwakafanana nekugezesa mvura kana kushandura kumvura yemubhodhoro zvakanyanya kuderedza kuwanda kwemutobvu weropa. Izvi zvakawanikwa zvinosimbisa kukosha kwekubvisa masosi ekutungamira muhurongwa hwemvura kuchengetedza hutano hweveruzhinji.
Kukosha kweBrass Tee Fittings muMvura Systems
Brass Tee Fittings inoita basa rakakosha mune zvese zvekugara uye zvekutengesa masisitimu ekugovera mvura.
