||Manganese and its compounds

||Occupational exposures to manganese and its compounds are mainly encountered in the steel and smelting industries, as well as in welding. Other industries such as dry cell manufacture, glassworks, and the production of paints and pigments can give also rise to exposures, as can certain pesticides used in agriculture. Occupational exposure to manganese occurs almost exclusively through inhalation, with the lungs and the central nervous system being the main target organs. In cases of chronic exposure, neurological disorders and in particular perceptual-motor performance, constitute the main critical effect. Higher exposures (generally above 5mg/m3) give rise to Parkinson-like symptoms. The identification of groups of exposed workers is possible by means of determinations in blood or urine. Monitoring of manganese exposure rests mainly on atmospheric sampling. Acceptable occupational exposure levels are 0.050 and 0.200mg/m3 respectively for respirable and inhalable fractions.
