Abstract

Background: The impact of heat waves and atmospheric oxidising pollutants on residential mortality within the framework of global climate change has become increasingly important.

Objective: In this research, the interactive effects of heat waves and oxidising pollutants on the risk of residential mortality in Fuzhou were examined. Methods We collected environmental, meteorological, and residential mortality data in Fuzhou from 1 January 2016, to 31 December 2021. We then applied a generalised additive model, distributed lagged nonlinear model, and bivariate three-dimensional model to investigate the effects and interactions of various atmospheric oxidising pollutants and heat waves on the risk of residential mortality.

Results: Atmospheric oxidising pollutants increased the risk of residential mortality at lower concentrations, and O3 and Ox were positively associated with a maximum risk of 2.19% (95% CI: 0.74-3.66) and 1.29% (95% CI: 0.51-2.08). The risk of residential mortality increased with increasing temperature, with a strong and long-lasting effect and a maximum cumulative lagged effect of 1.11% (95% CI: 1.01, 1.23). Furthermore, an interaction between atmospheric oxidising pollutants and heat waves may have occurred: the larger effects in the longest cumulative lag time on residential mortality per 10 µg/m3 increase in O3, NO2 and Ox during heat waves compared to non-heat waves were [-3.81% (95% CI: -14.82, 8.63)]; [-0.45% (95% CI: -2.67, 1.81)]; [67.90% (95% CI: 11.55, 152.71)]; 16.37% (95% CI: 2.43, 32.20)]; [-3.00% (95% CI: -20.80, 18.79)]; [-0.30% (95% CI: -3.53, 3.04)]. The risk on heat wave days was significantly higher than that on non-heat wave days and higher than the separate effects of oxidising pollutants and heat waves.

Conclusions: Overall, we found some evidence suggesting that heat waves increase the impact of oxidising atmospheric pollutants on residential mortality to some extent.

大气氧化污染物和热浪对居民死亡风险的交互影响。

背景：在全球气候变化的框架下，热浪和大气氧化污染物对居民死亡的影响变得越来越重要：本研究探讨了热浪和氧化污染物对福州居民死亡风险的交互影响。方法：我们收集了福州从 2016 年 1 月 1 日至 2021 年 12 月 31 日的环境、气象和居民死亡数据。然后，我们应用广义加法模型、分布式滞后非线性模型和双变量三维模型研究了各种大气氧化污染物和热浪对居民死亡风险的影响和相互作用：大气氧化污染物在浓度较低时增加了居民死亡风险，O3 和 Ox 与居民死亡风险呈正相关，最大风险分别为 2.19% (95% CI: 0.74-3.66) 和 1.29% (95% CI: 0.51-2.08)。居民死亡风险随着温度的升高而增加，具有强烈而持久的影响，最大累积滞后效应为 1.11% (95% CI: 1.01, 1.23)。此外，大气氧化污染物与热浪之间可能存在相互作用：与非热浪相比，热浪期间 O3、NO2 和 Ox 每增加 10 µg/m3 对居民死亡率的最大累积滞后效应为 [-3.81%（95% 置信区间：-14.82，8.63）]；[-0.45%（95% 置信区间：-2.67，1.81）]；[67.90%（95% 置信区间：11.55，152.71）]；[16.37%（95% 置信区间：2.43，32.20）]；[-3.00%（95% 置信区间：-20.80，18.79）]；[-0.30%（95% 置信区间：-3.53，3.04）]。热浪天的风险明显高于非热浪天，也高于氧化污染物和热浪的单独影响：总之，我们发现一些证据表明，热浪在一定程度上增加了氧化性大气污染物对居民死亡率的影响。

期刊介绍： Global Health Action is an international peer-reviewed Open Access journal affiliated with the Unit of Epidemiology and Global Health, Department of Public Health and Clinical Medicine at Umeå University, Sweden. The Unit hosts the Umeå International School of Public Health and the Umeå Centre for Global Health Research. Vision: Our vision is to be a leading journal in the global health field, narrowing health information gaps and contributing to the implementation of policies and actions that lead to improved global health. Aim: The widening gap between the winners and losers of globalisation presents major public health challenges. To meet these challenges, it is crucial to generate new knowledge and evidence in the field and in settings where the evidence is lacking, as well as to bridge the gaps between existing knowledge and implementation of relevant findings. Thus, the aim of Global Health Action is to contribute to fuelling a more concrete, hands-on approach to addressing global health challenges. Manuscripts suggesting strategies for practical interventions and research implementations where none already exist are specifically welcomed. Further, the journal encourages articles from low- and middle-income countries, while also welcoming articles originated from South-South and South-North collaborations. All articles are expected to address a global agenda and include a strong implementation or policy component.
