Irhasi eveliswe ngokufudumeza i-Asphalt

I-asphalt eshushu ikhupha iigesi ezenziwe ikakhulu ziihydrocarbons ezahlukeneyo, ingakumbi i-polycyclic aromatics hydrocarbons.

Asphalt’s composition includes asphaltenes, iintlazi, iihydrocarbons ezihluthisiweyo kunye nevumba elimnandi.

Ngenxa yonyango oluphezulu lobushushu okanye ukuphuphuma kwamanzi okwandisiweyo kwendalo, i-petroleum, netela yetha yamalahle, inkqubo yokufudumala ivelisa izinto ezincinci ze-molecular, ikakhulu ikhonkco elide kunye neehydrocarbons ezinevumba elimnandi, notably significant molecules such as naphthalene, ianthracene, phenanthrene, and benzo[a]pyrene.

Polycyclic aromatic hydrocarbons are notably toxic and some are known carcinogens.
