Effect of maternal exposure to carbon black nanoparticle on male offspring body weight

Group name	Number of dams (Number of offspring)	Age	Body weight (g)
Control (Ultra-pure water)	5 (18)	6 weeks	33 ± 2
Low-dose CB-NP (2.9 μg/kg)	5 (18)	6 weeks	35 ± 3
Middle dose CB-NP (15 μg/kg)	5 (19)	6 weeks	33 ± 2
High dose CB-NP (73 μg/kg)	5 (20)	6 weeks	32 ± 1

There were no significant between-group differences. Data are presented as the mean ± standard deviation. Abbreviations: CB-NP carbon black nanoparticle
