A few of the results certainty ask for a re-roll for what's under the initial result, if you want to keep that fairly normal roll 1d20 or 1d50.

Mercury likely gives off toxic fumes, don't fall in lava and falling in acid is probably a bad idea for dungeon explorers as well.  Blood, Pus, and Sewage will likely spread diseases. Cryptic Flesh and Titanic Organ can be infested with parasites or of couse be attached to somethign no one wants to wake up.

Any water could be a magical pool.
