背景资料：人们越来越担心接触再生轮胎橡胶释放的有毒物质，这种橡胶通常用于合成草坪和操场垫。为了更好地估计儿童对用于人造草坪和操场垫的再生轮胎橡胶的接触和风险，需要收集有关口吸活动和皮肤接触行为的详细准确信息。本研究的目的是量化和分析微观层次的活动时间序列（MLATS）数据，从1-12岁的儿童，而玩（非运动相关的游戏）在草坪一样的位置和游乐场。另一个目的是估计儿童偶然摄入橡胶屑的比率。研究方法：计算在草坪上玩耍的儿童的手和嘴接触频率、每小时持续时间和与不同物体接触的中位持续时间（即，公园、草坪和花园）（n = 56）和在游乐场结构上玩耍的儿童（n = 24）。对男性和女性以及儿童年龄组之间的统计学显著差异进行了评估。计算了大鼠每日偶然摄食橡胶粉的比率。结果如下：对于在草坪上玩耍的儿童，年龄较小（1-6岁）和年龄较大（7-12岁）的儿童在非饮食对象和所有对象的吸吮中位持续时间方面存在显着差异。对于在游乐场结构上玩耍的儿童，我们发现年幼（1-6岁）和年长（7-12岁）的儿童对所有物体的吸吮频率存在显着差异，并且对于非饮食物体的吸吮中位数持续时间。男性和女性在人造草坪或运动场垫子上玩耍没有显着差异。我们估计，<2岁、2-6岁和6-11岁儿童的平均偶然摄入率分别为0.08、0.07和0.08 g橡胶屑/天。讨论内容：我们的研究结果表明，年龄和接触时间应考虑在风险评估模型，以评估儿童在人造草坪表面或游乐场垫子上玩耍时的口形活动。
Background: There are growing health concerns about exposure to toxicants released from recycled tire rubber, which is commonly used in synthetic turf and playground mats. To better estimate children’s exposure and risk from recycled tire rubber used in synthetic turf and playground mats, there is a need to collect detailed accurate information on mouthing activity and dermal contact behaviors. The objective of this study was to quantify and analyze micro-level activity time series (MLATS) data from children aged 1–12 years old while playing (non-sport-related games) at turf-like locations and playgrounds. Another objective was to estimate the incidental ingestion rate of rubber crumb among children. Methods: Hand and mouth contact frequency, hourly duration, and median contact duration with different objects were calculated for children playing on turf (i.e., parks, lawns, and gardens) (n = 56) and for children playing on playground structures (n = 24). Statistically significant differences between males and females as well as children’s age groups were evaluated. The daily incidental ingestion rate of rubber crumb was calculated. Results: For children playing on turf, there were significant differences between younger (1–6 y) and older (7–12 y) children for the mouthing median duration with non-dietary objects and all objects. For children playing on playground structures, we found significant mouthing frequency differences between younger (1–6 y) and older children (7–12 y) with all objects, and for mouthing median duration with non-dietary objects. There were no significant differences between males and females playing on artificial turf-like surfaces or playground mats. Our estimated mean incidental ingestion rate was 0.08, 0.07, and 0.08 g rubber crumb/day for children <2, 2–6, and 6–11 years old, respectively. Discussion: our results suggest that age and contact duration should be considered in risk assessment models to evaluate mouthing activities when children are playing on artificial turf surfaces or playground mats.
