Potential chronic health

Prolonged and repeated exposure to crystalline silica containing dust can result in injury to the lungs. This condition is known as silicosis. Silicosis is characterized by shortness of breath, decreased expansion of the chest, dry cough, leading to fatigue, dyspnea, and cyanosis, loss of appetite, pleuritic pain and decreased work capacity. (Note: crystalline silica is not expected to be released from this bonded matrix.) Carcinogenicity: Crystalline silica is listed by IARC as a class 1, carcinogenic to humans, listed by NTP as a known to be a human carcinogen, and listed by NIOSH as a carcinogen. Carbon black is an IARC class 2B carcinogen (possibly carcinogenic to humans: limited evidence in humans in the absence of sufficient evidence in experimental animals).
