Generally, there can be a relationship of exposure level reaction, that is, the greater the exposure intensity (concentration), the more obvious the body reaction. (3) There are often a certain number of cases among people exposed to the same harmful factors, and there are rarely only a few patients. (4) Early diagnosis, timely treatment and proper treatment can delay the illness.
