Surface and Bulk chemistry of metals in atmospherically-relevant systems that impact climate and health

由于气溶胶和建筑物的高度复杂的物理化学性质，与大气相关的表面对气候和健康的总体影响仍然不确定。国家和国际各级监管者使用的新政策和模式需要以实验数据为基础，考虑到这些系统在夜间和白天条件下的表面化学。这些系统中的金属和有机生色团会产生活性氧物种，影响大气的氧化能力和建筑物的结构完整性，如果吸入，会对呼吸器官造成损害。关于这些反应在降解这些大气系统中普遍存在的有机物方面的重要性，以及它们在产生次生有机物和有害气相物种方面的作用，人们知之甚少。在没有太阳辐射和存在太阳辐射的情况下，需要对气溶胶和建筑物的表面化学进行实验和计算研究，以便与相同化学品的体相化学进行比较。

The overall impact of atmospherically-relevant surfaces of aerosols and buildings on climate and health remains uncertain due to their highly complex physicochemical properties. New policies and models used by regulators at the national and international levels need to be based on experimental data that take into account the surface chemistry of these systems under night- and day-time conditions. Metals and organic chromophores in these systems produce reactive oxygen species that impact the oxidative power of the atmosphere, structural integrity of buildings, and in case of inhalation, cause damage to the respiratory organs. Little is known about the importance of these reactions in degrading organics ubiquitous in these atmospheric systems, and their role in producing secondary organic matter and harmful gas phase species. Experimental and computational studies are needed on the surface chemistry of aerosols and buildings in the absence and presence of solar radiation for comparison with bulk phase chemistry of the same chemicals.
