TL;DR: In this paper, a review of the sources of polycyclic aromatic hydrocarbons (PAHs) in the environment is presented, where various approaches including diagnostic ratio (DR) and principal component analysis (PCA) are discussed in detail.

TL;DR: In this article, chemical weather forecasting models are described and compared on regional and continental scales in Europe, and the most prominent gaps of knowledge are highlighted for the following selected focus areas: emission inventories, the integration of numerical weather prediction and atmospheric chemical transport models, boundary conditions and nesting of models, data assimilation of the various chemical species, improved understanding and parameterization of physical processes, better evaluation of models against data and the construction of model ensembles.

TL;DR: A comprehensive review of the current research status of online coupled meteorology and atmospheric chemistry modelling within Europe and highlights selected scientific issues and emerging challenges that require proper consideration to improve the reliability and usability of these models for the three scientific communities.

TL;DR: This study indicates that the association between PM in air pollution and lung cancer can be attributed to various PM components and sources, and PM containing S and Ni might be particularly important.

TL;DR: In this paper, the authors quantify exhaust/non-exhaust emissions and the uncertainties associated with them by combining innovative motorway tunnel sampling and source apportionment modelling, and use principal component analysis and multiple linear regression analysis to identify the emission sources for 82% of the total PM 10 mass inside the tunnel.
