　　Although asphalt is toxic, its use is still relatively common in developed countries due to its widespread use in waterproofing and road construction.

　　瀝青中的毒性物質通常是非揮發(fā)性的，但在高溫加熱時，一些成分可能會揮發(fā)，產(chǎn)生有害煙霧。

　　The toxic substances in asphalt are usually non-volatile, but some components may evaporate and produce harmful smoke when heated at high temperatures.

　　預防措施 ：

　　Preventive measures:

　　在生產(chǎn)和使用瀝青時，應注意勞動保護，避免直接皮膚接觸和吸入瀝青煙霧。

　　When producing and using asphalt, attention should be paid to labor protection, avoiding direct skin contact and inhalation of asphalt smoke.

　　如果皮膚不慎接觸到瀝青，可以用適當?shù)那鍧崉┻M行清洗。

　　If the skin accidentally comes into contact with asphalt, it can be cleaned with a suitable cleaning agent.

　　綜上所述，瀝青確實具有毒性，并且可能對人體健康造成危害，尤其是長期或直接接觸。因此，在處理瀝青時應采取適當?shù)姆雷o措施。

　　In summary, asphalt is indeed toxic and may pose a risk to human health, especially through long-term or direct contact. Therefore, appropriate protective measures should be taken when handling asphalt.
