Nhamba uye tsvagiridzo inoratidza kuti huwandu hwejecha neguruva maitiro muEast Asia panguva imwe chete ingangoita 5-6, uye gore rino jecha uye guruva mamiriro ekunze zvakapfuura avhareji yemakore apfuura. Kuratidzwa kwakanyanya kwehurongwa hwekufema kwemunhu kune huwandu hwakanyanya hwejecha uye guruva zvimedu zvinogona kupfupisa avhareji yehupenyu hunotarisirwa, kuwedzera huwandu hwechiitiko chechirwere chemoyo uye chekufema, uye kuratidza chiitiko chakakosha. Kuwedzera kune pesvedzero yezvimedu zvakakura, zvimedu zvakanaka (PM2.5) uye ultrafine particles (PM0.1) mujecha neguruva zvinogona kupinda mumuviri wemunhu nekuda kwehukuru hwavo hudiki, zvichiunza kukuvadza kukuru kuhutano hwevanhu.
Nzvimbo dzine jecha rakanyanyisa uye guruva mazinga akatopa mitemo yekumisa basa rekunze, uye njodzi dzayo dzakavanzwa dzinobuda pachena, sezvo mamiriro ekunze akaipa achigonawo kukonzera kumwe kukuvadza kuhutano hwevanhu.
Nzira yekutora matanho ekudzivirira?
Edza kudzivirira kuita mabasa ekunze, kunyanya kune vakwegura, vana, neavo vane zvirwere zvekufema, uye nekukasika kuvhara magonhi nemahwindo mukati memba.
·Kana uchida kubuda, unofanira kuuya nemidziyo yekudzivirira huruva yakaita semasks nemagogi kudzivirira kukuvadzwa kwenzira yekufema nemaziso zvinokonzerwa nejecha neguruva.
·Dutu rejecha rinogona kuita kunhuwa kwakasimba kwetsvina pamba, inogona kucheneswa nemuchina wekutsvaira kana mucheka wakanyorova kudzivirira kumiswa kweguruva remukati.
·Mafirita emhepo emukati kana mafirita emhepo anogona kuve akashongedzerwa kana mamiriro achibvumidza, ayo anogona kuchenesa mweya wemukati nekuuraya nemavhairasi nemabhakitiriya ari mumhepo.
·SAF multistage air filtration system ine mafirita emhepo emazinga akasiyana ekusefa kuderedza kuwanda kweguruva uye microbial aerosols mumhepo.
Isu tinoshandisa mabhegi mafirita uye mafirita ebhokisi sezvikamu zviviri-matanho ekutanga kusefa kuti abvise zvakakoshera uye zvepakati zvinoshanda zvimedu.
Iyo EPA, HEPA, uye ULPA mafirita eSAF anoshanda seyekupedzisira nhanho mafirita, ane basa rekunyatsobata zvidiki zvidiki uye mabhakitiriya.
