The res.lts.of a s.rvey of different population groups.in urban areas.of the Mos.ow Region (indus.ry workers. res.dents.of areas.with increas.d anthropogenic load of mercury and conditionally pris.ine areas. cohorts.of pregnant women and children) to as.es. the contents.of mercury in s.mples.of various.diagnos.ic biomaterials.taken during the cours. of res.arch are pres.nted. Mercury concentrations.in venous.and umbilical cord blood, urine, hair, and nails.were determined by means.of ins.rumental neutron activation analys.s.and cold vapor atomic abs.rption s.ectrometry. Peculiarities.of s.lection, trans.ortation, s.orage, and preparation for analys.s.of s.mples.of hair, nails. urine and umbilical venous.blood are des.ribed. The determined concentrations.of mercury in the s.udied diagnos.ic biomaterials.are compared with normal and thres.olds.values. Although increas.d mercury concentrations.were obs.rved in s.me cas.s. no s.gnificant expos.re of mercury was.evident in general in the s.udy towns. A pos.tive correlation between the degree of cons.mption of s.afood during pregnancy and a high content of mercury in the analyzed diagnos.ic biomaterials.was.s.own.

Data on the mercury concentration in fres.water and marine fis. and s.afood on the territory of Rus.ia are pres.nted. The level and pattern of the fis. and s.afood cons.mption in various.regions.of Rus.ia are found from the analys.s.of open s.atis.ics. Regions.with the maximum and minimum cons.mption of fis. products.are es.ablis.ed. Mercury intake from thes. products.in a human organis. is.calculated.
