One of the causes of this increased risk is because PM exposure increases the incidence and severity of respiratory infections. The respiratory system is particularly vulnerable to air pollution and its impact on infection as it is a key site for exposure both to inhaled pollutants and infectious microbes or viruses. This review examines the current understanding of how PM affects antiviral host defense responses and possible underlying mechanisms.</p><p><strong>Recent findings: </strong>While numerous studies have associated adverse health outcomes with combined or sequential exposure to inhaled pollutants and viruses, defining causal relationships and mechanisms remains limited. Particularly limited, are contemporary data focuses on low- and middle-income countries, including heavily polluted regions such as Ulaanbaatar, Mongolia. This manuscript focuses on how (1) PM, serving as a carrier for viruses, enhances the transmission of viruses; (2) PM impairs immune defense to viruses; and (3) PM impacts epithelial cell functions to exacerbate viral infections. Given the significant public health hazards on PM, particularly in heavily polluted regions such as Southeast Asia, Middle East and Africa, it is critical to define specific mechanisms of PM on respiratory infection and how their impact may differ in these highly polluted regions. Ultimately, this could devise future public health measures and interventions to limit this substantial public health risk.</p>","PeriodicalId":10775,"journal":{"name":"Current Environmental Health Reports","volume":"12 1","pages":"22"},"PeriodicalIF":7.4,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143970063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is especially true when considering the differences in disease severity and progression brought on by exposure to toxic metals. A current area of interest is understanding how exposure to toxic heavy metals manifests differently in males and females. The present work assesses the potential sex-differences in diseases induced by arsenic, lead, cadmium, and chromium. These specific heavy metals are included in a wealth of literature supporting their induction of diseases that negatively impact health.</p><p><strong>Recent findings: </strong>Arsenic toxicity appears to effect males significantly more than females. This is largely due to males having decreased arsenic methylation ability compared to females. Lead is a potent neurotoxicant that induces developmental and behavioral deficits in young children. While these deficits are seen in both sexes, the specific aspects of behavior and development affected differ between males and females. Research shows females absorb more cadmium from the gastrointestinal tract, correlating with a rich history of cadmium-induced renal dysfunction. Occupational exposure is a significant factor when considering chromium toxicity. Males are much more likely to work in industrial positions where chromium exposure is common, resulting in more males suffering the consequences of chromium exposure than females.
