Kuyaziwa njenge imvula eneasidi kuleyo nqubo lapho umswakama ojwayelekile emoyeni uhlanganiswa khona nezinto ze- ukungcola yamadolobha (i-sulfur dioxide ne-nitrogen oxide), evumela ukwakheka kwama-nitric ne-sulfuric acid angawela ngesimo semvula. Njengoba kwaziwa kahle, imvula ene-asidi ingaletha umonakalo omkhulu ezikhaleni ezingagezwa yiyo, ngakho-ke ake sifunde kabanzi ngemiphumela engayenza.
Yini ebangela imvula eneasidi? Njengoba sisho amagesi angcolisayo kukhishwa njengamalahle no-oyela, okuthi uma kuxutshwe nomphunga wamanzi kube yi-sulfuric acid ne-nitric acid.
Phakathi kokumbalwa kobubi obuza ukubangela ukwehla kwalo sithola ukuthi kungenzeka ukuthi sikwazi ukonakalisa inamba enhle yezakhiwo zasemadolobheni, imabula noma i-limestone iphakathi kwezinto ezingathinteka kakhulu.
Ngaphandle kwalokhu, ake siqaphele ukuthi futhi inemiphumela emibi empilweni yemvelo, ukuthola inkinga enkulu lapho imvamisa iwela olwandle noma emachibini ngoba ngobuningi bayo ingathinta izinhlanzi ize ibangele ukufa kwazo ngendlela enkulu. Kubuye kube nzima ukukhula kahle kwezitshalo ngenxa yokuthinta inhlabathi yazo. Okubi kakhulu ngalokhu ukuthi amafu athwala imvula ene-asidi angahamba amakhilomitha ambalwa ngaphambi kokukhipha okuqukethwe kuwo.
Ingabe ikhona indlela yokulungisa le nkinga? Vele, isibonelo, inhloso kungaba ukwehlisa izinga lesibabule kumafutha, ukukhuthaza ukusetshenziswa kwegesi yemvelo, ukwandisa ubuchwepheshe bokuhambisa ugesi, phakathi kwabanye.
