Is hydrocarbon poisonous

Answer 1

Depends on the hydrocarbon :

Hydrocarbon gases are asphixiants and can be narcotic.

N-alkanes (straight chain hydrocarbons) up to about 10carbon atoms long have some toxicity, above that not so.

Aromatic hydrocarbons vary greatly in toxicity depending on size and side chain placement.

There is no "one size fits all" answer to this question.

Answer 2

Hydrocarbons themselves are not inherently poisonous. However, some specific hydrocarbons, such as benzene and toluene, can be toxic if inhaled, ingested, or absorbed through the skin in high amounts. It's important to handle and dispose of hydrocarbons properly to avoid potential health risks.
