What does it mean when you have black wax in your ears and black coming out of your nose?

Ear wax: As your question suggests, black ear wax or nasal mucous is not normal. When i see this, it is usually from exposure to something, like very dirty air, such as working in a manufacturing plant where there is a lot of dark colored particles floating in the air or a mechanics shop or outside doing something dirty like farming or even welding. It could also be that a little dried blood mixed in.
