    If the air you breathe is heavily laced with it, it will do a pretty good job of imitating toxic.
    Petcoke dust is not generally regulated as a toxic air contaminant.   Petcoke dust is regulated as an air pollution source of PM (particular matter), PM-10 and PM-2.5 (depending on aerodynamic diameter of particle emissions).

    Inhaled particles do not have to contain toxic constituents in order for such inhaled particles to have adverse health effects on respiratory health  (with the finest particles capable of causing the most respiratory health and cardiac effect).

    I suppose one could say wood smoke is not toxic either, but one can't breathe it for very long.
    The constituents of wood smoke are quite toxic and include far, far more toxic air contaminants as benzene soluable organic matter than would be released by storage of petroleum coke.
