Abstract We report atmospheric benzene measurements in the main metropolitan and industrial areas across Spain from 2014 to 2017 period. We have used hourly benzene levels measured at air-quality stations influenced by urban and industrial environments. Annual mean levels ranged between 0.3 and 2.4 μg m−3 with an hourly maximum values of 112 μg m−3 in Tarragona. Industrial stations can reach concentrations of one order of magnitude greater than urban sites. Higher annual averages are also reported in the industrial stations (maximum ~3.5 μg m−3 in Aviles). When the monthly pattern is taken into account, the industrial sites also presented higher values than urban sites; urban stations show higher monthly values always in winter, ranging between

2014 年至 2017 年西班牙主要城市和工业区的大气苯测量值

摘要 我们报告了 2014 年至 2017 年西班牙主要大都市和工业区的大气苯测量值。我们使用了在受城市和工业环境影响的空气质量站测量的每小时苯水平。塔拉戈纳的年平均水平介于 0.3 和 2.4 μg m-3 之间，每小时最大值为 112 μg m-3。工业站可以达到比城市站点大一个数量级的浓度。工业站也报告了更高的年平均值（在阿维莱斯最大~3.5 μg m-3）。考虑到月度模式，工业用地也呈现高于城市用地的值；城市站总是在冬季显示更高的月值，范围介于
