Ukungcoliswa komoya okuphezulu kwamadolobha kuphoqa izikhungo ukuba thatha izinyathelo zokuthuthukisa ikhwalithi yomoya. Iningi lokungcola emadolobheni amakhulu kungenxa yokuhamba nokusakazwa kwegazi. Ezikhungweni zedolobha imvamisa kuba nesiminyaminya, isiminyaminya nenqwaba yezimoto ezihamba ngasikhathi sinye (eziningi zazo zinomgibeli oyedwa kuphela).
Kungakho umkhandlu wedolobha laseValladolid unxuse omakhelwane ukuthi basebenzise kakhulu izithuthi zomphakathi noma basebenzise ibhayisikili ukuya emsebenzini noma ohambweni lwabo lwansuku zonke. Lokhu kudalwe yirekhodi lesiqephu sokungcoliswa komoya okuphezulu kakhulu ngenxa yokwanda kwe-nitrogen dioxide. Ngabe iqiniso lokuthi izakhamizi zithatha ibhayisikili lizosebenza ngokwengeziwe?
Irekhodi lesiqephu sokungcola okuphezulu
Lapho kubhaliswa isiqephu sokungcola okuphezulu edolobheni, izinyathelo ziyaqalwa ukuxazulula inkinga futhi, ngaphezu kwalokho, kumenyezelwa izindlela zokuvimbela isiqephu esiphakeme kangako ukuthi singaphinde senzeke. Izolo eValladolid kufinyelelwe kukho qopha ama-micrograms angu-187 ngemitha yomoya oyisithupha eziteshini ze-Arco Ladrillo ngo-20.00: 200 p.m. isikhathi selanga; Yize zingadluli umkhawulo wekhwalithi yomoya wama-micrograms angama-XNUMX, zidinga isimo sokuvikela ukuthi sisebenze.
Ukuhlangana okuphezulu kokungcola emkhathini nokuphefumulelwa yizakhamizi kungakhuphula kakhulu isibalo sezifo eziphathelene nokuphefumula komzimba namacala esifuba somoya.
Ukungcola kubekelwe ukwanda
Ngenxa yama-anticyclone ayenzekayo, ukuhlakazeka kokungcola emadolobheni kuncane. Yingakho ukugxila kuqhubeka nokwanda futhi kulindeleke ukuthi kukhule ngokwengeziwe. Ukuze kulindelwe lokhu kukhuphuka okungenzeka, okudlula ama-micrograms angama-200 nge-cubic meter yomoya, uMkhandlu Wedolobha unxuse izakhamizi ukuthi zisebenzise izithuthi zomphakathi noma amabhayisikili.
Kulesi simo lapho ukungcola kuyanda, kungaholela ekuvinjelweni komgwaqo engxenyeni yomlando wedolobha. UMkhandlu Wedolobha ukhumbule ukuthi i-nitrogen dioxide ingadala ukusabela kokuvuvukala emaphashini nasekuphenduleni kwesifuba.
