"could easily"

I just asked ChatGPT: when using a fry pan, does the smoke contain formaldehyde and benzene?

    > Cooking at very high temperatures (over 450°F or 232°C), especially with oils or fats, could theoretically contribute to benzene formation.

That is a mighty hot fry pan. The hottest cooking that I know of in common practice is "wok hei"-style from China. When you start cooking, the food rarely exceeds 230C. When you are heating the pan, the oil may exceed 230C for a few seconds. If you use a fry pan, but cook in Mediterranean-style, the temperatures are much lower.

"could easily"? Hardly.
