Question

Quizplus · Accepted Answer

Polycyclic hydrocarbons are the most recalcitrant because they are highly resistant to degradation by natural processes and can persist in the environment for long periods of time. They are also known to have harmful effects on human health and the environment. Straight-chain hydrocarbons and shorter hydrocarbons such as ethane and propane are more easily broken down by microbes and other natural processes.
