According to the number of accumulated cases, foundry workers'pneumoconiosis, silicosis, welders' pneumoconiosis, asbestosis and carbon black pneumoconiosis ranked the top 5 in number. Foundry workers' pneumoconiosis and silicosis cases were 421, which accounted for 84.88%. Most of these cases occurred in workers served in steel foundry, construction material mining and processing, refractory and glass manufacturing industries. The average age at diagnosis was (51.97& #177;9.26)years old, and the average working age of all cases was(21.75& #177;9.97)years old.
