The polycyclic aromatic hydrocarbons are a group of chemical substances present in the atmosphere which are known to be a cause of lung cancer. They are formed when carbon-containing fuels such as coal, oil or gas are burned, as well as being emitted from some industrial processes such as aluminium smelting. Whilst road vehicles and home heating are known to be significant sources, the relative amounts coming from different sources are not well known and this research intends to use measurements of these compounds in the atmosphere to infer which sources are mainly responsible. It is also known that polycyclic aromatic hydrocarbons are changed by chemical reactions in the atmosphere but the rates of these reactions are not well known and these are also to be studied. These reactions cause the formation of other chemicals known as PAH-derivatives for which measurement methods will be developed. The outcome will be a much improved understanding of the sources and processes affecting these compounds in the atmosphere leading ultimately to the possibility of more cost-effective control measures being taken.

多环芳烃是大气中存在的一组化学物质，该化学物质已知是肺癌的原因。当燃烧煤炭，石油或天然气等含碳燃料，并从铝冶炼等某些工业过程中散发出来时，它们就会形成。虽然已知道路车辆和家庭供暖是重要的来源，但来自不同来源的相对数量并不众所周知，该研究打算在大气中使用这些化合物的测量来推断哪些来源主要负责。还知道，多环芳族烃会因大气中的化学反应而改变，但是这些反应的速率尚不清楚，也需要研究这些反应。这些反应导致形成其他称为PAH衍生物的化学物质，以此为其进行测量方法。结果将是对影响大气中这些化合物的来源和过程的大大改善，最终导致采取更具成本效益的控制措施的可能性。
