The concentrations ratios of specific pairs of polycyclic aromatic hydrocarbons (PAHs) are widely used for the qualitative determination of the PAHs sources. These ratios are called PAHs molecular diagnostic ratios and are commonly used for PAHs concentrations in air, soils and sediments. Some scientists have extended the use of these ratios also for sewage sludges, suggesting that calculation of these ratios by individual PAHs concentrations can be as effective as in soils or sediments. This paper describes the reason why the PAH molecular ratios calculated from sewage sludge concentrations should not be used for the understanding of the PAH sources.
特定多环芳烃（PAHs）对的浓度比被广泛用于定性确定PAHs的来源。这些比值被称为PAHs分子诊断比值，常用于空气、土壤和沉积物中的PAHs浓度测定。一些科学家还将这些比值的应用扩展到了污水污泥中，认为通过单个PAHs浓度计算这些比值在污水污泥中与在土壤或沉积物中一样有效。本文阐述了为何不应使用根据污水污泥浓度计算出的PAH分子比值来理解PAH的来源。
