As a group of typical endocrine disrupters, phthalates are simultaneously present in a variety of environmental media and enter human body through multiple exposure pathways. In this study, field monitoring data were used to characterize the skin-air (K ), dust-air (K ), and PM -air (K ) partition coefficients of DiBP, DnBP, and DEHP. The median values of log(K ) in the summer and winter were 7.654 and 7.932, 7.265 and 7.902, 9.419 and 9.015 for DiBP, DnBP, and DEHP, respectively, and K was significantly higher in the winter. The median K (m /mg) in the summer (0.036-0.151 for DiBP, 0.021-0.036 for DnBP and 1.479-4.069 for DEHP) were significantly higher than the counterparts in the winter (0.027-0.065 for DiBP, 0.022-0.245 for DnBP, and 0.140-3.250 for DEHP). In addition, K was associated with material of surface and residence time of dust. The K values (m /μg) of DiBP, DnBP, and DEHP in the summer (0.053, 0.015, and 0.021) were also significantly higher than the counterparts in the winter (0.011, 0.004, and 0.025). The partition of phthalates was influenced by built environment, such as temperature, humidity, ventilation, indoor chemistry, smoking, and building age. Except K , there was substantial discrepancy between the estimates of K with empirical equations and the values of K based on field monitoring data in our study.
作为一组典型的内分泌干扰物，邻苯二甲酸酯同时存在于多种环境介质中，并通过多种暴露途径进入人体。本研究利用现场监测数据，描述了 DiBP、DnBP 和 DEHP 的皮肤-空气（K）、灰尘-空气（K）和 PM-空气（K）分配系数。夏季和冬季 log(K) 的中位数分别为 DiBP、DnBP 和 DEHP 的 7.654 和 7.932、7.265 和 7.902、9.419 和 9.015，冬季 K 值显著更高。夏季（0.036-0.151 为 DiBP、0.021-0.036 为 DnBP 和 1.479-4.069 为 DEHP）的 K（mg/m）中位数显著高于冬季（0.027-0.065 为 DiBP、0.022-0.245 为 DnBP 和 0.140-3.250 为 DEHP）。此外，K 值与灰尘表面材料和停留时间有关。夏季 DiBP、DnBP 和 DEHP 的 K 值（μg/m）也显著高于冬季（0.053、0.015 和 0.021）。夏季（0.011、0.004 和 0.025）。本研究中，除 K 值外，经验方程估算的 K 值与现场监测数据得到的 K 值之间存在显著差异。邻苯二甲酸酯的分配受建筑环境的影响，如温度、湿度、通风、室内化学、吸烟和建筑年龄。
