The heavy line in Figure 3 represents the mean curve (n=ll) for the change in plasma manganese and the other lines show the typical plasma responses of individual subjects (n 5). The mean increase in plasma manganese peaked at hour 1, at approximately 103% above fasting. The mean concentrations of plasma manganese were 0.64, 1.29, 1.12, 0.94 and 0.75 ug/L at hours 0,1,2,3, and 4 postdose,...

Striatum. Red blood cell and plasma manganese levels were increased only in rats exposed to the highest dose for the 10-day exposure period. These data indicate that even at lower doses manganese can accumulate in the olfactory bulb. However, it must be noted that tissues were collected and analyzed at the cessation of exposure. It is not clear if the distribution of manganese would be similar if tissues had been analyzed at a later time.

Samples Analyzed by Inductively Coupled Plasma (ICP) Metals — Where two or more of the following analytes are requested on the same filter, an ICP analysis may be conducted. However, the Industrial Hygienist should specify the metals of interest in the event samples cannot be analyzed by the ICP method. A computer print-out of the following 13 analytes may be typically reported Antimony, Beryllium, Cadmium, Chromium, Cobalt, Copper, Iron, Lead, Manganese, Molybdenum, Nickel, Vanadium, Zinc. Arsenic — Lead, cadmium, copper, and iron can be analyzed on the same filter with arsenic.

Chappie and Byrne [743] applied an electrothermal vaporisation inductively coupled plasma technique to the determination of copper, cobalt, manganese, nickel, and vanadium in seawater in amounts down to 3-140 ppt. 

The line at 2287.7 cm"1 in InP visible in Fig. 18 is clearly the same as the one observed in plasma diffused sample by Pajot et al. (1989) and which is the spectroscopic evidence of the zinc acceptor neutralized by hydrogen. The line at 2272 cm"1 observed only in InP doped with manganese is very... 

The body contains only 20 mg of manganese, found mostly in the bones and glands. The plasma level is low, about 2.5 meg/dl. 

There is concern that elevated environmental levels of manganese resulting, for example, from the introduction Mn-containing additives to petrol, might be associated with neurological disease. Direct EPR spectroscopy has been used to monitor Mn(II) following the addition of Mn(II) and Mn(III) complexes to human blood plasma and cell lysates.49...
