Seasonal variations were seen for the n-alkanes, but, surprisingly, not for the PAHs, although the content of PAHs in cold seasons is higher than in warm seasons. The average concentration of the sum of n-alkanes from n-C18H38 up to n-C33H68 is 43.0 Myg/l, that of the sum of 11 PAHs is 525 Myg/l.enGas-Chromatographiegas chromatographyhigh performance liquid chromatographyHochleistungsflüssigchromatographiehydrocarbonKohlenwasserstoffNiederschlagpolycyclic aromatic hydrocarbonpolyzyklischer aromatischer KohlenwasserstoffprecipitationrainrainwaterRegenRegenwasser615610620book article
