Wood burning and shipping emissions represent two poorly understood sources of primary and secondary organic aerosol (POA and SOA) responsible for serious health and environmental effects. The gas/particle interactions and their effect on particle composition will be studied using a comprehensive set of on-line and off-line analytical techniques. Important aims include the quantification and chemical characterization of primary organic aerosols and secondary organic aerosols, estimation of health effects via measurement of reactive oxygen species (ROS), and assessment of the stability of individual organic markers. As research on emissions form deep-sea navigation is only just beginning, measurement of the physicochemical properties of the direct particle emissions are value of themselves, while the controlled aging experiments in a mobile smog chamber are completely new. For the wood combustion experiments, the purpose is the quantitative characterization of the total aerosol produced under conditions relevant for wintertime domestic wood combustion. Previous wood combustion studies have not been conducted at lower temperatures (i.e. ~0 °C), which is expected to influence SOA formation, portioning of SOA and POA, and the ageing processes of components such as ROS. Experiments at these temperatures, enabled by the mobile smog chamber, will lead to more realistic results that are crucial for accurate description of the important partitioning effects affecting organic molecules.

木材燃烧和航运排放是造成严重健康和环境影响的两个知之甚少的一次和二次有机气溶胶（POA和SOA）来源。将使用一套全面的在线和离线分析技术研究气体/颗粒相互作用及其对颗粒组成的影响。重要目标包括初级有机气溶胶和次级有机气溶胶的定量和化学表征，通过测量活性氧（ROS）估计健康影响，以及评估单个有机标志物的稳定性。由于深海航行排放物的研究才刚刚起步，直接排放物的物理化学性质的测量本身就具有很大的价值，而在移动的烟雾室中进行受控老化实验则是一项全新的研究。对于木材燃烧实验，目的是在冬季家用木材燃烧相关条件下产生的总气溶胶的定量表征。以前的木材燃烧研究没有在较低的温度（即~0 °C）下进行，这预计会影响SOA的形成，SOA和POA的分配以及ROS等成分的老化过程。在这些温度下的实验，使移动的烟雾室，将导致更现实的结果，是至关重要的影响有机分子的重要分配效应的准确描述。
