356. 硅胶烘焙模具中环状硅氧烷暴露评估
from 知为谁 · host 知为谁
该科学研究评估了使用硅胶烘焙模具时,人类通过吸入和食物摄入暴露于环状硅氧烷(c-siloxanes)的风险。研究团队测量了来自25种加拿大市场上新烘焙模具中c-siloxanes的含量,并模拟了烘焙过程中这些化学物质向食物和室内空气的迁移与释放。基于这些测量数据,研究估算了不同年龄组人群(特别是儿童)通过这两种途径的日暴露剂量,发现儿童按体重计的暴露水平最高。最后,作者强调了长期链c-siloxanes(如D7至D16)的毒性数据缺乏,并指出重复使用模具可以显著降低c-siloxanes的迁移和释放量。内容来源:https://www.sciencedirect.com/science/article/pii/S0304389425025105
