We recruited 467 pregnant women, collecting venous blood and sociodemographic information as well as placental cord blood at birth. Metallic/semimetallic trace elements were measured using inductively coupled plasma mass spectrometry. Lead medians in maternal and cord blood were significantly correlated (Spearman coefficient=0.59; p<0.001; 19.35 and 13.50g/L, respectively). Arsenic concentrations were above detection limit (3.30g/L) in 17.9% of maternal and 34.6% of cord blood samples. They were not associated (Fischer's p=0.72). Antimony medians in maternal and cord blood were weakly correlated (Spearman coefficient=0.15; p<0.03; 9.00 and 8.62g/L, respectively). Higher concentrations of toxic elements in maternal blood were associated with maternal smoking, low educational level, and partner involved in mining. specialized environmental exposure metallic trace elements maternal exposure prenatal exposure risk factors BOLIVIE ORURO 064 038 056 050 26 2 158-174 2016 0960-3123 https://www.documentation.ird.fr/hor/fdi:010066161 10.1080/09603123.2015.1061114 0960-3123 [F B010066161] https://www.documentation.ird.fr/hor/fdi:010066161 https://www.documentation.ird.fr/intranet/publi/2016/02/010066161.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2016-02-26 2017-08-23 fdi:010066161 fre
