Hur lång tid tar det för asfaltbeläggning att bli giftfri

Typically, the process spans around 20 days. Petroleum asphalt commonly exhibits low toxicity, primarily emitting aromatic hydrocarbons. Conversely, coal tar asphalt, rich in benzene-related volatiles, is notably more toxic.

While these substances are inherently toxic, significant exposure over time is generally necessary to manifest toxic effects.
