Popis: Children growth and development may be affected by metal exposure. The objective of the present study was to investigate the interactive effects of age and gender on children hair toxic metal levels in urban environment of two Russian cities. A total of 2021 children living in Moscow and Novosibirsk aged 1–18 years old were examined. Hair Al, As, Cd, Hg, Ni, Pb and Sn levels were assessed using inductively-coupled plasma mass-spectrometry in dynamic reaction cell mode. Children from Novosibirsk were characterised by higher hair Al (37%), As (385%), Cd (127%), Hg (11%), Ni (23%), Pb (72%) and Sn (25%) in comparison to Moscow values. In the general cohort, boys had higher Al (13%), As (51%), Cd (65%), Pb (63%) and Sn (18%) levels, whereas hair Ni was higher in girls (17%). Further analysis demonstrated age-specific gender differences. In particular, only hair Ni and Cd levels were higher in male toddlers and pre-schoolers from Novosibirsk as compared to females. No gender difference was detected in ...
