Phenol, nitrophenols and dinitrophenols were measured in air and dews in downtown Santiago de Chile. In both systems, phenol, 2-nitrophenol (2-NP), and 4-nitrophenol (4-NP) were the compounds found in higher concentrations and with major frequency. Temporal profiles in air were compatible with a significant direct incorporation from mobile sources. The data can be explained in terms of a faster removal of 2-NP than 4-NP, with the former predominating in fresh air masses and 4-NP in more aged samples. All these compounds, as well as dinitrophenols, were found in dew waters. Simultaneous measurements in air and dew indicate that phenol present in dew exceeds that expected in equilibrated samples, while the opposite occurs with 4-NP. This last result is associated to mass transfer limitations for the highly water soluble nitroderivative.
在智利圣地亚哥市中心的空气中和露水中测量了苯酚、硝基酚和二硝基酚。在这两种体系中，均发现了浓度更高且更为常见的化合物，包括苯酚、2-硝基酚（2-NP）和 4-硝基酚（4-NP）。空气中的时间分布与来自移动源的显著直接吸收相吻合。这些数据可以通过 2-NP 的去除速度快于 4-NP 得到解释，前者在新鲜空气团中占主导地位，而 4-NP 在更老化的样本中占主导地位。所有这些化合物，以及二硝基酚，都在露水中被发现。空气中和露水中的同时测量表明，露水中的苯酚含量超过了平衡样品中预期的含量，而 4-NP 则相反。这一最后结果与高度水溶性的硝基衍生物的传质限制有关。
