11.2 Additional Information
anemia, Throat., Men exposed to manganese dusts showed a decrease in fertility.
Chronic manganese poisoning primarily involves the central nervous system. Early symptoms include languor, sleepiness and weakness in the legs. A stolid mask-like appearance of the face, emotional disturbances such as uncontrollable laughter and a spastic gait with tendency to fall in walking are findings in more advanced cases.
High incidence of pneumonia has been found in workers exposed to the dust or fume of some manganese compounds., Cough, Shortness of breath, Headache
