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

气溶胶和建筑物的大气相关表面对气候和健康的总体影响仍然不确定，因为它们具有高度复杂的物理化学性质。国家和国际两级监管机构采用的新政策和模型需要以实验数据为基础，这些数据要考虑到这些系统在夜间和白天条件下的表面化学性质。这些系统中的金属和有机发色团会产生活性氧，影响大气的氧化能力、建筑物的结构完整性，如果吸入，会对呼吸器官造成损害。这些反应在降解这些大气系统中无处不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知之甚少。需要在有无太阳辐射的情况下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.
