Gurbatar muhalli
Kowane nau'in sufuri yana gurɓata mahalli, amma fa'idar fa'ida - 85% na gurɓatarwa ana aiwatar dashi ta hanyar jigilar hanya, wanda ke fitar da iskar gas. Motoci, bas da sauran motocin wannan nau'in suna haifar da matsaloli daban-daban:

Jirgin ruwa
Jirgin ruwa yana gurɓatar da ruwa mafi yawa, tunda ruwa mai ƙyalƙyali da ruwa wanda ake amfani dashi don wanke tasoshin ninkaya sun shiga cikin magudanan ruwa. Plantsarfin wutar lantarki na jirgi suna gurɓata iska da iskar gas iri-iri. Idan tankokin dakon kaya suna dauke da kayan mai, akwai yiwuwar gurbatar mai a cikin ruwan.
Jirgin sama
Jirgin sama da farko yana gurɓata yanayi. Tushen su shine gas din injina jirgin sama. Jirgin sama yana fitar da iskar carbon dioxide da nitrogen oxides, tururin ruwa da sulphur oxides, carbon oxides da ƙananan abubuwa a cikin iska.
Jigilar lantarki
