Significant progress in understanding the effects of neurotoxic action lead (Pb) young organisms had led to reduction "safe" level blood (Pb-B) 5 μg/dL children and pregnant women. Prolonged exposure relatively low levels Pb, generally asymptomatic subclinical (i.e., microintoxication), is currently dominant form environmental poisoning, its negative on health may appear after many years, e.g., secondary contamination from Pb bone deposits released pregnancy. Therefore, aim this study was investigate effect (urban areas) mothers their milk newborns. Moreover, determine fatty acid profile mothers' We also wanted find if infant birth weight depends levels, as well mothers. Finally, we examined body mass index (BMI) before pregnancy influenced concentration children. Analysis acids elaidic (C18:1, 9t), oleic 9c), vaccenic 11t), cis-vaccenic 11c), linoleic (C18:2, cis), γ-linolenic (C18:3, n-6), α-linolenic n-3), arachidonic (C20:4, eicosapentaenoic (C20:5, docosahexaenoic (C22:6, n-3) conducted by gas chromatography. The whole were determined atomic absorption spectrometry with graphite furnace atomization Zeeman correction. Our established a significant strong correlation between content mother child. This supports assumption that transport through placenta neither regulated nor selective. Environmental maternal resulting Pb-B considered safe for women no weight, mothers, or Mothers' BMI studied profile.
