| pubmed-article:1290563 | pubmed:abstractText | Human biological samples using the atomic emission method. The concentration of 27 micro- and macro elements was specified in a total number of 1221. Some of the patients tested were under hospital treatment because of chronic disease (727 persons), others were blood donors (71 persons) or pregnant women and newborn infants (107-107 persons, respectively). In the serum samples of the tested persons the concentration of barium, mercury, nickel and gallium showed characteristic differences. Concentrations of many micro elements in the serum and cerebrospinal fluid changed with age and sex. The tendency becomes characteristic after the age of 45 and 60, respectively. The concentration of elements in the blood serum of mothers and their newborn infants seems to be nearly identical with a considerable deviation observed only in case of aluminum, barium and iron (significant difference). The detected elements can pass through the placenta. This particularly applies to lead because the average lead concentration in the serum of newborn infants is 159 micrograms/litre even at birth. | lld:pubmed |
