Impact of environmental microplastics on maternal and fetal health / 中华围产医学杂志

ABSTRACT

Microplastics refer to plastic fibers, particles, or films with a particle size less than 5 mm, and microplastics pollution has become one of the major global environmental problems. Microplastics can be exposed to the human body through ingestion, inhalation and skin contact, affecting maternal and fetal health through mechanisms such as cytotoxicity and signal transduction, energy homeostasis and metabolic disorders, immune dysfunction, and as carriers of microorganisms or toxic chemicals. The purpose of this paper is to review the physical and chemical properties of microplastics, human exposure pathways, maternal-fetal effects, and its mechanisms.
