Question Is this rust?

While disassembling a bathroom fan unit, I found a considerable amount of powdery, brownish dust inside the fan housing, as seen in the picture below. Is this rust? From the color and scent, it looks like rust. If it is, where did the fan pick it up?

It is likely not rust but just dust/dirt from the air. I have seen it many times on fans that I have replaced. Could also be face powder from applying makeup so smoke from candles or cigarettes.
