图5 基于BKMR模型分析出生前母体4种重（类）金属暴露对幼儿认知和气质发育影响的主导性 Note： The models were adjusted for maternal age, maternal education, gestational age, child age, and child sex. The impact of prenatal maternal exposure to various heavy metals/metalloid on the changes in fine motor DQ (A), and adaptability (B)/persistence (C)/threshold of response (D) dimension scores across different exposure levels was assessed. The figures illustrated the associations between the concentration of a specific heavy metal/metalloid and changes in the DQ value or dimension scores, while the concentration levels of the other three were fixed at the 50th percentile.
