摘　　要：Bioaerosols are a subset of important airborne particulates that present a substantial human health hazard due to their allergenicity and infectivity.Chemical reactions in atmospheric processes can significantly influence the health hazard presented by bioaerosols;however,few studies have summarized such alterations to bioaerosols and the mechanisms involved.In this paper,we systematically review the chemical modifications of bioaerosols and the impact on their health effects,mainly focusing on the exacerbation of allergic diseases such as asthma,rhinitis,and bronchitis.Oxidation,nitration,and oligomerization induced by hydroxyl radicals,ozone,and nitrogen dioxide are the major chemical modifications affecting bioaerosols,all of which can aggravate allergenicity mainly through immunoglobulin E pathways.Such processes can even interact with climate change including the greenhouse effect,suggesting the importance of bioaerosols in the future implementation of carbon neutralization strategies.In summary,the chemical modification of bioaerosols and the subsequent impact on health hazards indicate that the combined management of both chemical and biological components is required to mitigate the health hazards of particulate air pollution.
