Why is coal ash harmful?



  1. 0 Votes

    Coal ash and waste is so harmful because of the toxins it is made up of, which pose serious health risks to humans. Two of the more well known toxins found in coal ash are arsenic and lead. Arsenic can cause cancer of the lungs, kidney, bladder, prostate and skin, while lead has been linked with developmental disabilities in children involving both the brain and the nervous system. 

    Coal ash also has more radioactive material in it than nuclear waste, as coal contains both uranium and thorium. When coal is burned, these radioactive elements concentrate and increase the ash’s level of radiation. Ash can permeate ecosystems through soil and waterways, and can do a great deal of damage.
