A simple, “your scaling argument doesn’t really apply since the amount of residue left behind scales with the volume, not area” would have sufficed.
Gasoline is a pretty powerful solvent; would residue left behind that doesn’t come off from gasoline be liberated by cooking oil? It’s an honest question.
And I sure hope the regulatory agencies and shipping companies in my country do a better job than in China. This sort of thing is terrifying; I’m just curious as to an emotionless analysis of how bad this likely is. What concentration of benzene is acceptable? “None” would be best but we already breathe it. Would contaminated cooking oil likely be equivalent to…inhaling once at a gas station? A wet martini with diesel instead of vermouth?
…scaling laws. They are best illustrated with different sized items. Like a thimble, a coffee cup, or an oil tanker, all representing volumes of different orders of magnitude.
