What is the black stuff coming out of my oak tree?
That “black stuff” is the result of a bacterial infection called Wetwood or Slime Flux. These particular bacteria thrive in anaerobic (low oxygen) conditions present in the dense interior hardwood. As the anaerobic bacteria ferment and release carbon dioxide, it creates pressure forcing liquid from woods in the trunk.
What causes wood to go black?
Iron oxide stains in wood are usually dark spots caused by prolonged exposure to water and / or metal. The iron oxide reacts with the tannins in the wood and stains it black. Wood can intentionally be stained black in the same way, and that's called Ebonizing.

What happens if you get soot in your lungs?
Inhaling fine particles can cause a variety of health effects, including respiratory irritation and shortness of breath, and can worsen medical conditions such as asthma and heart disease. During increased physical exertion, cardiovascular effects can be worsened by exposure to carbon monoxide and particulate matter.
Does soot stay in your lungs?
