Abstract

A sample of 30 manganese-exposed foundry workers from two Swedish plants were examined with a partly computerized psychological test battery, comprised of 10 performance tests. Performance of the manganese-exposed workers was compared to that of a matched control group of 60 workers. Matching criteria were age, geographical area, type of work, and the results on a test of verbal comprehension. Performance of the exposed workers was inferior to that of the control group on tests of simple reaction time, digit span, and finger tapping. No correlations were found between performance and the present manganese exposure levels or the number of years employed in manganese work. The results seem to indicate that the present exposure standards for manganese, in Sweden 2.5 mg/m3 and in most other countries 5 mg/m3, are not sufficient to protect workers from negative effects on performance capacity.

    In contrast, MOF treatment did not affect the percentage of DC, CD4+ T and CD8+ T cells in the spleen (Fig. S7 in Supplementary data). This strongly suggests that activation of anti-tumor immunity by Mn-MOF@PEG only limited to the cancerous sites, which is a highly desirable property to diminish potential side effects of Manganese (Mn) [21]. Compared with other Mn containing agents such as MnO2 nanoparticles or MnCl2 solutions [19], Mn-MOF@PEG could be effectively uptaken by cancerous sites and locally releasing Mn ions, thanks to its pH dependent degradation behaviors and PEG facilitated blood circulation.
