Abstract

To date, a limited number of studies have assessed the impact of individual and combined PM_2.5 components on mumps incidence. Between 2013 and 2019, we collected data on 6,270 mumps cases in Lanzhou, along with corresponding PM_2.5 and its components, to analyze their temporal and spatial distributions. A generalized additive mixture model was constructed to examine the association between PM_2.5 components and mumps incidence. Additionally, Bayesian kernel machine regression was used to evaluate the combined and interactive effects of co-exposure to PM_2.5 components on mumps incidence and to identify key contributing components. A significant linear correlation was found between PM_2.5 and mumps incidence at lag 1 month, with a relative risk (RR) of 1.85 (95% CI: 1.14, 3.02) for each unit increase in PM_2.5 (ln (PM_2.5) = 1 μg/m³). Organic matter (OM) at lag 0 and 1 month, as well as black carbon (BC) at lag 1 month, were significantly positively correlated with mumps incidence. Furthermore, the joint exposure-effect curve for PM_2.5 components and mumps incidence displayed an approximate V-shape. The effects of PM_2.5 and its components on mumps incidence were more pronounced during the warm season. These findings suggest a significant association between short-term exposure to PM_2.5 and its components and mumps incidence in Lanzhou, with potential variations in effect depending on the specific components of PM_2.5.

期刊介绍： Environmental Pollution is an international peer-reviewed journal that publishes high-quality research papers and review articles covering all aspects of environmental pollution and its impacts on ecosystems and human health. Subject areas include, but are not limited to: • Sources and occurrences of pollutants that are clearly defined and measured in environmental compartments, food and food-related items, and human bodies; • Interlinks between contaminant exposure and biological, ecological, and human health effects, including those of climate change; • Contaminants of emerging concerns (including but not limited to antibiotic resistant microorganisms or genes, microplastics/nanoplastics, electronic wastes, light, and noise) and/or their biological, ecological, or human health effects; • Laboratory and field studies on the remediation/mitigation of environmental pollution via new techniques and with clear links to biological, ecological, or human health effects; • Modeling of pollution processes, patterns, or trends that is of clear environmental and/or human health interest; • New techniques that measure and examine environmental occurrences, transport, behavior, and effects of pollutants within the environment or the laboratory, provided that they can be clearly used to address problems within regional or global environmental compartments.
