This news is based on the following article: Cheng L, Zhang B, Zheng T, et al. Critical windows of prenatal exposure to cadmium and size at birth. Int J Environ Res Public Health 2017; 14: 58. doi: 10.3390/ijerph14010058
This study differs from previous ones in that it uses a longitudinal collection of maternal urine samples to examine the association between size at birth and fetal cadmium exposure during each trimester of pregnancy. The results suggest that early in utero life is a critical window for the adverse effects of cadmium on fetal growth, which have been observed only in girls.
