Title Iron, copper and manganese metabolism in workers performing heavy physical work
Original title Obmen železa, medi i marganca v organizme rabočih pri tjaželom fizičeskom trude [in Russian]
Bibliographic information Sep. 1983, No.9, p.21-24. 8 ref.
Abstract Examinations of 19 forging-shop workers showed that plasma iron levels were maximal in autumn and winter and minimal in spring and summer. The lowest levels of iron in the blood constituents were also found in the summer. Copper and manganese levels remained constant throughout the year. Iron in both blood fractions and copper in the plasma were lower after a work shift than before; manganese remained unchanged. Measurements of dietary intake and excretion of the 3 elements showed that the workers were in negative iron and manganese balance in winter and especially in summer. This probably reflects an excessive proportion of iron and manganese-poor vegetables in the diet and can be corrected by changes in, or suplements to, the diet.
