Dusts and fibres | Inorganic dusts | Specify: Other
|
| |
Ultrafine particles, manganese
|
|
Comments
|
| |
Analyses have been performed based on plant and department allocation of the workers, with the presumption that employment in furnace halls implicates exposure to ultrafine particles
|
| 4. OUTCOMES EVALUATED |
