If I'm reading https://www.bls.gov/cps/cpsaat18.htm correctly, ~82% of waste collectors are male.

On the other hand, ~42% of meat processors are women; that is certainly a dirty, dangerous unfun job.

The real male-dominated industries are lawn care, sewage treatment, and repair and maintenance. Coal mining is too small an industry to report demographics, but mining as a whole is "only" ~88% male.
