Box-plot showing the relationship of toxic metals among the maternal blood, cord blood and placenta. a Copper (Cu). b Selenium (Se). c Zinc (Zn). d Arsenic (As). e Cadmium (Cd). f Lead (Pb). g Total mercury (THg). h Antimony (Sb). The number of samples above LOD in the maternal blood, cord blood and placenta. Statistical analyses were performed by nonparametric Kruskal-Wallis followed by Dunn test. Significantly different (**P < 0.01), As and Pb: maternal blood (MB) and placenta (PL) > cord blood (CB), Cd: PL > MB > CB, Cu: MB > PL > CB, Se: PL > CB > MB, Sb: PL and CB > MB, THg: PL > CB > MB, Zn: PL > MB > CB
