摘要: The aim of the present study was to examine body burden lead (Pb), mercury (Hg), and cadmium (Cd) in blood among Swedish adults association between levels, diet other lifestyle factors. based on a subgroup (n = 273) national survey Riksmaten 2010-2011 (4-day food records questionnaire). Lead, Hg, Cd were measured whole blood, additionally urine, by mass or fluorescence spectrometry methods. median values (5-95th percentiles) metals as follows: Pb: 13.4 (5.8-28.6) mu g/L, Hg: 1.13 (0.31-3.45) Cd: 0.19 (0.09-1.08) g/L. All three increased with increasing age. Lead levels positively associated intakes game alcohol, Hg related fish intake, smoking low iron stores meat intake. Body burdens studied generally below health reference values, but several individuals had Pb above point for possible nephrotoxic developmental neurotoxic effects. As effects cannot be excluded, high exposure should at decreasing their burden, both from routes. (c) 2013 Elsevier Ltd. rights reserved. (Less)
