PM_2.5 chemical constituents and allergic rhinitis: Findings from a prospective cohort study in China

Long-term exposure to PM2.5 chemical constituents and diabesity: evidence from a multi-center cohort study in China

“… 22 The 3-year average concentrations of PM 2.5 and its chemical constituents over the residence of the participants preceding the survey were calculated as surrogates of the individuals’ exposures to PM 2.5 and its chemical constituents. 23 …”

“…Additionally, PM 2.5 is a complex mixture of chemical constituents, mainly including secondary inorganic aerosols such as sulfate (SO 4 2− ), nitrate (NO 3 − ), ammonium (NH 4 + ), organic matter, and black carbon, 12 which may have varying health effects. 13 To accurately predict the effects of PM 2.5 on diabesity, it is necessary to investigate the contribution of each chemical constituent to their joint effects on diabesity. However, this may be difficult to achieve by the commonly used parametric regression, due to high correlations among those chemical constituents.…”

Resolving the etiology and treatments of allergic diseases

“…In this context，a recent low‐latitude multi‐city study from China has demonstrated that increases in air pollutant concentrations and changes in meteorological conditions (temperature, humidity, and wind speed) might be associated with the number of outpatient visits for allergic rhinitis (AR) 7 . Accordingly, addressing both air pollution and climate change by imposing strict governmental policies might lower the incidence of allergic decrease and long‐lasting health effects 8 . The role of lipids from sebaceous glands in barrier dysfunction of atopic dermatitis (AD) has been under‐recognized.…”

“…7 Accordingly, addressing both air pollution and climate change by imposing strict governmental policies might lower the incidence of allergic decrease and long-lasting health effects. 8 The role of lipids from sebaceous glands in barrier dysfunction of atopic dermatitis (AD) has been under-recognized. Yin and colleagues 9 noticed that aberrant lipid metabolism in sebaceous glands was correlated with skin inflammation and barrier dysfunction, and contributed to the pathogenesis of AD.…”

EAACI guidelines on environmental science for allergy and asthma: The impact of short‐term exposure to outdoor air pollutants on asthma‐related outcomes and recommendations for mitigation measures

“…asthma, environmental science, guidelines, outdoor pollution healthcare resources, including visits to emergency department and hospital admissions. 11,[13][14][15][16][17][18][19][20] However, epidemiological studies have often yielded inconsistent findings, and not all studies have found significant associations, 21 which may be related to both variations in statistical, measurement and modelling methodologies between studies and differences between countries and/or regions in the concentrations and composition of outdoor air pollution.…”
