“…The problem of haze pollution reflects the condition of air quality, which affects people’s health and is closely related to people’s productivity and life [ 6 , 7 ]. At present, studies of haze pollution mainly focus on its spatial evolutionary characteristics, spatial differences [ 8 ], health effects [ 9 , 10 ] and influencing factors [ 11 , 12 ].…”

The development of the digital economy holds great significance for alleviating haze pollution. To estimate the impact of the digital economy on haze pollution, this paper explores the spatiotemporal evolutionary characteristics of the digital economy and PM2.5 concentration in the middle and lower reaches of the Yellow River Basin from 2011 to 2019 and conducts regression analysis by combining a fixed effect (FE) model and the spatial Durbin model (SDM). Moreover, this study divides the mitigation effect of haze pollution into a direct effect and a spatial spillover effect, and it further analyzes the mechanism from the perspectives of technological innovation and the industrial structure. The empirical results show that the development level of the digital economy increases year by year and that the concentration of PM2.5 decreases year by year. The digital economy level and PM2.5 concentration in the downstream region are higher than those in the middle region, and the digital economy is negatively correlated with haze pollution. Similarly, the spatial spillover effect of the digital economy is conducive to curbing haze pollution. The robustness test also supports this conclusion. In addition, there is regional heterogeneity in the impact of the digital economy on haze pollution. The direct effect and spatial spillover effect of the digital economy on haze pollution in the downstream region are greater than those in the middle region. This study suggests that to realize air pollution prevention and control, it is necessary to strengthen the construction of digital infrastructure and create a good digital economy development environment based on local conditions. Encouraging the development of digital technological innovation and promoting industrial digital transformation hold great significance for alleviating haze pollution.

“…In the single-component model, sulfate, nitrate, ammonium, and organic matter showed comparable estimates with the result of PM 2.5 total mass. Considering any potential interaction of the intake of PM 2.5 components ( Li et al, 2022 ), we applied the QGC model for multiple components and noticed that the effect of the PM 2.5 mixture was mainly dominated by nitrate, sulfate, and organic matter. Although ammonium was positively associated with SPROM in the single-pollutant model, it did not show a similar effect in the mixture analysis.…”

“…Like PM 2.5 , our study showed that chronic exposure to PM 2.5 constituents was also significantly linked with HTN, stage 1 HTN, and stage 2 HTN, with and being the most substantial adverse effect, followed by , OM, and BC. To our knowledge, only one study has examined the relationship between PM 2.5 components and stage 1 HTN, which showed that PM 2.5 components ( , , , OM, and BC) were positively associated with the risk of stage 1 HTN, with the BC being the strongest adverse effect [ 54 ]. Due to the different units of ORs, the results between the two studies lacked comparability.…”

Background Studies have shown that nutritional supplements could reduce the adverse effects induced by air pollution. However, whether dietary patterns can modify the association of long-term exposure to fine particulate matter (PM2.5) and its constituents with hypertension defined by the 2017 ACC/AHA guideline has not been evaluated. Methods We included 47,501 Chinese adults from a nationwide cross-sectional study. PM2.5 and five constituents were estimated by satellite-based random forest models. Dietary approaches to stop hypertension (DASH) and alternative Mediterranean diet (AMED) scores were calculated for each participant. Interactions between dietary patterns and air pollution were examined by adding a multiplicative interaction term to logistic models. Results Long-term exposure to PM2.5 and its constituents was associated with an increased risk of hypertension and stage 1–2 hypertension. The DASH and AMED scores significantly modified these associations, as individuals with higher scores had a significantly lower risk of air pollution-related hypertension and stage 1–2 hypertension (P-interaction < 0.05), except for interaction between PM2.5, sulfate, nitrate, ammonium, and AMED score on stage 1 hypertension. For each IQR increase in PM2.5, participants with the lowest DASH and AMED quintiles had hypertension risk with ORs (95%CI) of 1.20 (1.10, 1.30) and 1.19 (1.09, 1.29), whereas those with the highest DASH and AMED quintiles had lower risks with 0.98 (0.91, 1.05) and 1.04 (0.97, 1.11). The stratified analysis found modification effect was more prominent in the < 65 years age group. Consuming more fresh vegetables, fruits, whole grains, and dairy would reduce the risk of hypertension caused by PM2.5 and its constituents. Conclusions Dietary patterns rich in antioxidants can reduce long-term exposure to PM2.5 and its constituents-induced hypertension defined by the 2017 ACC/AHA guideline, especially in young and middle-aged individuals. Compared to the Mediterranean diet, the DASH diet offers superior dietary guidance to prevent stage 1 hypertension caused by air pollution.
