描述和研究了估计参与流行病学队列研究的个体累积环境空气污染浓度的方法。使用从加利福尼亚州固定站点监测站到邮政编码质心的每月插值。对总悬浮颗粒物和臭氧插值方法的精度进行了评估，并依次采用固定点监测站作为接收点。实际与插值 2 年平均浓度没有显着差异，并且与总悬浮颗粒物的皮尔逊相关系数 0.78 和臭氧的皮尔逊相关系数 0.87 相关。评估了监测总氧化剂改为监测臭氧对氧化剂/臭氧累积量的影响，并将同时测量两种污染物的 435 个站月的总氧化剂月平均浓度与臭氧进行了比较。平均浓度没有显着差异并且高度相关（r = 0.94）。臭氧的超标频率统计数据平均略高于总氧化剂，也具有高度相关性。
Methods for estimating cumulative ambient air pollution concentrations for individuals enrolled in an epidemiological cohort study are described and studied. Monthly interpolations from fixed-site monitoring stations in California to zip code centroids were used. The precision of the interpolation methods for total suspended particulates and ozone was assessed, and fixed-site monitoring stations were used in turn as receptor sites. Actual versus interpolated 2-y mean concentrations did not differ significantly and were correlated with a Pearson correlation coefficient of .78 for total suspended particulates and .87 for ozone. The impact of the change from monitoring total oxidants to ozone on oxidant/ozone cumulations was evaluated, and monthly mean concentrations for total oxidants were compared with ozone for 435 station months during which both pollutants were measured simultaneously. Average concentrations did not differ significantly and were highly correlated (r = 0.94). Exceedance frequency statistics, which averaged slightly higher for ozone than for total oxidants, were also highly correlated.
