| Abstract: |
| Mouthing behavior is essential and important in the growth and development of children．Children may touch or place all those objects in contact with their mouths when they play or use baby products，thus leading to potential mechanical or chemical risks．At present，most of the chemical safety regulations and standards for toys and baby products worldwide are based on the safety risks assessed through mouthing exposure pathways．Herein，both home and abroad related researches on children’s mouthing contacts with objects are investigated thoroughly，and several aspects are emphasized．The research methods for collecting children’s mouthing behavior parameters are overviewed，and the mouthing behavior parameters of children are reviewed and summarized in terms of contact duration，contact frequency，bite force，mouth size and saliva composition，etc．The deficiencies in investigation on the parameters of children’s mouth based on the safety risk assessment of toy and baby products are analyzed，and finally，the development direction of the research on the exposure behavior and exposure risk based on toys and baby products is proposed．This investigation provides references for mouthing exposure risk assessment，detection and related standardization formulation of toy and baby products． |
