German Environmental Survey 1998 (GerES III): environmental pollutants in blood of the German population.
The German Environmental Survey was conducted for the third time in 1998 (GerES III). The probability sample of about 4800 subjects was selected to be representative for the German population with regard to region (East-/West-Germany), community size, age (18 to 69 years) and gender. Blood samples were taken from each study participant and questionnaires were used to get exposure-related information. Cadmium, lead, mercury, hexachlorobenzene (HCB), hexachlorocyclohexane (alpha-HCH, beta-HCH, gamma-HCH), 1,1-dichloro-2,2-bis(p-chlorophenyl)ethylene (p, p'-DDE) and polychlorinated biphenyls (PCB-138, PCB-153, PCB-180) were analysed in whole blood to document the extent, distribution, and determinants of exposure of the general population to these substances. The geometric means of Cd, Pb, and Hg in blood amounted to 0.44, 31, and 0.58 microgram/l, respectively. Smokers showed a Cadmium level of 1.1 micrograms/l and non-smokers a level of 0.28 microgram/l. The geometric mean of lead was higher in the blood of males than of females (36 micrograms/l vs. 26 micrograms/l). The concentration of mercury in blood depends on fish consumption and the number of teeth with amalgam fillings. The mean concentrations of HCB and p, p'-DDE in blood were 0.44 microgram/l and 1.6 micrograms/l, respectively. In East-Germany (the former GDR) the DDE concentration in blood was more than twice as high as in West-Germany. Geometric means for PCB were 0.42, 0.68 and 0.44 microgram/l for PCB-138, PCB-153, and PCB-180, respectively. A marked increase of HCB, DDE and PCB levels with age could be observed. alpha-HCH and gamma-HCH could be detected in 1.7% and 5.2% of the samples only. beta-HCH was quantified in 34% of the samples with a 95th percentile of 0.5 microgram/l.
