“…At higher Mn-exposure levels, Flinn et al (1941) observed leucopenia in 7 of 11 intoxicated workers, whereas Rodier (1955) noticed a relative increase in lymphocytes and a decrease in polymorphonuclear leukocytes. Polymorphonuclear leukocytosis was reported in two Mn steel workers with chronic neurological disease (Whitlock et al, 1966).…”

“…The nearby presence of industrial point sources of manganiferous emissions can produce pronounced deviations from normal background levels, the main industries implicated being ferroalloy factories, steel mills, ore crushing plants, welding activities, and dry cell battery manufacture. Manganiferous pollution associated with Mn ferroalloy plants can be especially polluting, with many early studies demonstrating atmospheric concentrations of Mn measurable in μg/m 3 or even mg/m 3 within or near such factories (Sabnis et al 1966;Whitlock et al 1966;Itakura and Tajima 1972;Suzuki et al 1973;Saric et al 1977;IPCS 1981;WHO 1987;IPCS 1999). Published data on atmospheric Mn levels around industrial point sources have tended to focus on the areas adjacent to the factories, and have rarely paid attention to the wider issue of raised background levels over a broader urban area.…”

“…34 Those exposed to manganese while working in the steel industry also may develop progressive parkinsonism. [35][36][37] Levodopa responsiveness in these parkinsonian subjects is transient and not associated with motor fluctuations. [39][40][41] Although our patients differ from the classic scenario of manganese exposures, this does not necessarily disprove the association.…”

“…[34][35][36][37][38] The syndrome, best characterized in Moroccan manganese miners, includes progressive parkinsonism, dystonia, and neuropsychiatric symptoms. 34 Those exposed to manganese while working in the steel industry also may develop progressive parkinsonism.…”
