摘要：
Phthalates have been strictly banned in children's products in many countries. However, as a product with a high frequency of daily contact with children, stationery is not strictly regulated for phthalates in many countries and the occurrences and risks of phthalates in stationery are rarely reported. In this study, the contents of sixteen types of common phthalates in stationery were determined and the exposure risk of these phthalates to children was also estimated. The total contents of phthalates in all stationery ranged from 5.56 to 3.46 × 105 μg/g, with a median value of 1.48 × 104 μg/g. Polyvinyl chloride (PVC) desk mats (DMs) contained the highest contents of phthalates among all types of stationery. Percutaneous absorption and hand-to-mouth ingestion levels of phthalates for school-age children from the DMs were 2.03 × 10−5 - 10.14 μg/kg-Bw/day and 2.14 × 10−5 - 10.67 μg/kg-Bw/day, respectively. Di-2-ethylhexyl phthalate (DEHP) had the highest proportion, detection rate, and exposure level among all measured phthalates. Our study revealed that phthalates in PVC stationery, especially classroom DMs, at both contents and exposure risks, were higher than those in many other children's plastic products. It was necessary to strengthen the management of plastic stationery from the perspective of materials and phthalates addition. © 2023 Elsevier Ltd
