Abstract

In the study of the interaction between atmospheric environment and indoor environment, there are two blind spots worthy of attention: 1) Little research has been done on the effects of radiation from nature on human health. In response to this shortcoming, the reporter studied the effects of outdoor and infiltrated particulate matter-related radiation on inflammatory markers and oxidative stress markers in patients with chronic pulmonary obstruction in the Boston area of the United States. It was first discovered that low concentrations of radiation in nature can significantly increase inflammatory and oxidative stress in patients with chronic pulmonary obstruction. 2) Research on the impact of indoor formaldehyde emission on the atmospheric environment is still vacant. As an important medium in atmospheric chemical reactions, the emission of formaldehyde increases the concentration of ozone and sulfate in the atmosphere. In China, the emission of formaldehyde in indoor building materials and furniture is quite serious. The reporter conducted an investigation into the distribution of indoor formaldehyde in nine provinces in the eastern part of China. Based on research and statistical analysis, it is confirmed that indoor formaldehyde emission is an important source of formaldehyde in the atmosphere: 3.72%-18.8% of the total formaldehyde emissions, and 2-3th among the 6 major anthropogenic sources.
