Abstract

Background: Increase in industrial pollution exposes human being to environmental pollution such as heavy metals, hydrocarbons and various pesticides. Mercury is an important pollutant affecting on fetus evolution. The goal of this work was determining the mercury levels of blood and body in mothers and newborns in Sabzevar city and relationship of these levels with living area, filled tooth, abortion and feeding regime. Methodology: Samples were prepared from 90 pregnant mothers referring to Shahidan Mobiny hospital for delivery. The samples were containing placenta, placenta blood, umbilical cord and blood of umbilical cord. Samples were analyzed by an ICP-OES (Inductively Coupled Plasma -OES) instrument to determine the exact values of mercury levels. Stata 12 software was used to statistical investigations. Results and conclusion: The average age of mothers was 27.11 and the average levels of mercury in placenta, placenta blood, umbilical cord and blood of umbilical cord were 10.64, 10.64, 12.16 and 9.09 µg/g, respectively. There was a strong and significant correlation between blood mercury of mothers and newborns (p<0.000). Findings revealed that the living area has a significant effect on mercury levels in mothers and infants. Filling teeth with amalgam had just a significant effect on the mercury level of umbilical cord blood (p<0.019). We concluded that fruits and vegetables feeding decrease the mercury levels in mothers and their infants.
