[Adverse maternal and infant health effects caused by thallium exposure during pregnancy].

Thallium is a highly toxic heavy metal. The adverse maternal and infant health effects caused by thallium exposure during pregnancy have also attracted more and more scholars' attention. This study focused on the sources of thallium exposure and its influencing factors, the association between thallium exposure during pregnancy and pregnancy complications and adverse birth outcomes in newborns, the effects of thallium exposure during pregnancy on children's growth and development after birth. In terms of potential mechanisms, the related research progress was reviewed in this study, which could provide a new basis for further research on the harm, prevention and control of thallium exposure during pregnancy.
