The historical record of the input of pyrolysis-derived pollutants via the atmosphere, i.e. black carbon (BC), polycyclic aromatic hydrocarbons (PAH) and spheroidal carbonaceous particles (SCP) was measured in the sediments of three remote alpine lakes situated in the Julian Alps, northwest Slovenia. Parallel sedimentary trends for BC, PAH and SCP were observed across the Julian Alps and relationships among these contaminants are discussed. Inputs of these pyrolytic-contaminants to sediments of remote lakes started to rise at the end of the 19th century, while their peak inputs were observed in the mid-20th century, amounting up to 6.0 gm(-2) yr(-1) for BC, 5200 x 10(4) m(-2) yr(-1) for SCP and 2900 microg m(-2) yr(-1) for PAH. In the last two to three decades, inputs decreased substantially, by a factor of up to 3 for BC, 7 for SCP and at least 3 for PAH.
通过大气输入的热解衍生污染物，即黑碳（BC）、多环芳烃（PAH）和球状碳质颗粒（SCP）的历史记录，在斯洛文尼亚西北部朱利安阿尔卑斯山的三个偏远高山湖泊的沉积物中进行了测量。在整个朱利安阿尔卑斯山观察到了BC、PAH和SCP的平行沉积趋势，并讨论了这些污染物之间的关系。这些热解污染物向偏远湖泊沉积物中的输入在19世纪末开始上升，而在20世纪中叶观察到它们的输入峰值，BC高达6.0 g m(-2) yr(-1)，SCP为5200×10(4) m(-2) yr(-1)，PAH为2900 μg m(-2) yr(-1)。在过去的二三十年中，输入量大幅下降，BC下降了高达3倍，SCP下降了7倍，PAH至少下降了3倍。
