“…A growing number of studies have shown a negative correlation between air pollutant exposure (longterm or short-term) and individual cognitive function, especially PM 2.5 . [45][46][47] The results of our study also con rmed these ndings. Air pollution reduces individuals' cognitive-related semantic memory and visual construction abilities.…”

“…[49] In particular, people with different levels of cognitive function are affected differently by air pollution exposure-the lower the individual's basal cognitive function, the greater the impact of exposure on cognition. [45] This study also found interactions between open-air activities and SO 2 emissions and PM 2.5 concentrations. When pollutant concentrations (or emissions) were low, the positive effects of exercise overwhelmed the negative effects of air pollution, whereas when pollutant concentrations (or emissions) were high, the act of regular open-air activity instead impaired cognitive function.…”

“…This was consistent with the results of previous studies. [45,52] Therefore, the effects of environmental factors should also be considered when advocating exercise for seniors. Documents such as the Chinese Health Guidelines for the Elderly (2013 edition) [53] also need to be further updated.…”

Background: Based on the complexity of cognitive-related influences and the specificity of Chinese liquor culture, this study aimed to explore the associations and potential interactions between demographic characteristics, alcohol consumption, life and atmospheric environment and cognitive function in seniors through a comprehensive analysis, in order to provide evidence support and feasible recommendations.Methods: The study sample was selected from the Chinese Longitudinal Healthy Longevity Survey, which included 40,583 seniors aged 65-115 years. Data analysis and processing were performed by R 4.0.4. The relationship between the factors and cognition was modeled and analyzed by generalized additive model, and the interaction was explored by combining the ANOVA.Results: The generalized additive model confirmed that alcohol consumption was detrimental to the cognitive status of older adults, especially for liquor (≥ 38º) and beer. The higher the average daily alcohol consumption, the greater the impairment. SO2 and PM2.5 showed the same negative effects. In contrast, life environment factors such as good education, balanced diet and positive activity participation had a positive effect on cognition in seniors. In addition, interactions between alcohol consumption and average daily alcohol consumption, frequency of vegetable and meat intake, and between open-air activities and air pollution were also confirmed.Conclusions: Poor lifestyle choices such as alcohol consumption, unbalanced diet, lower activity participation, and air pollution deteriorate cognitive function in seniors. It is recommended that the elderly population should avoid alcohol consumption, maintain a balanced diet and be physically active. Attention should also be paid to the effects of air quality.

“…Long-term or short-term exposure to air pollution were widely reported to associate with increased all-cause, respiratory, and/or circulatory mortality [ 9 – 13 ]. In addition, studies have shown that exposure to air pollutants was associated with risk of out-of-hospital cardiac arrest, diabetes, cancer, and increased risk of death and cognitive decline [ 14 – 18 ]. Exposure to PM 2.5 and O 3 , is not only harmful to human health but also associated with a substantial disease burden [ 19 ] and economic loss [ 20 ].…”

Short-term effect of fine particulate matter and ozone on non-accidental mortality and respiratory mortality in Lishui district, China

Background In recent years, air pollution has become an imminent problem in China. Few studies have investigated the impact of air pollution on the mortality of the middle-aged and elderly people. Therefore, this study aims to evaluate the impact of PM2.5 (fine particulate matter) and O3 (ozone) on non-accidental mortality and respiratory mortality of the middle-aged and elderly people in Lishui District of Nanjing and provide the evidence for potential prevention and control measures of air pollution. Method Using daily mortality and atmospheric monitoring data from 2015 to 2019, we applied a generalized additive model with time-series analysis to evaluate the association of PM2.5 and O3 exposure with daily non-accidental mortality and respiratory mortality in Lishui District. Using the population attributable fractions to estimate the death burden caused by short-term exposure to O3 and PM2.5。. Result For every 10 μg/m3 increase in PM2.5, non-accidental mortality increased 0.94% with 95% confidence interval (CI) between 0.05 and 1.83%, and PM2.5 had a more profound impact on females than males. For every 10 μg/m3 increase in O3, respiratory mortality increased 1.35% (95% CI: 0.05, 2.66%) and O3 had a more profound impact on males than females. Compared with the single pollutant model, impact of the two-pollutant model on non-accidental mortality and respiratory mortality slightly decreased. In summer and winter as opposed to the other seasons, O3 had a more obvious impact on non-accidental mortality. The population attributable fractions of non-accidental mortality were 0.84% (95% CI:0.00, 1.63%) for PM2.5 and respiratory mortality were 0.14% (95% CI:0.01, 0.26%) for O3. For every 10 μg/m3 decrease in PM2.5, 122 (95% CI: 6, 237) non-accidental deaths could be avoided. For every 10 μg/m3 decrease in O3, 10 (95% CI: 1, 38) respiratory deaths could be avoided. Conclusion PM2.5 and O3 could significantly increase the risk of non-accidental and respiratory mortality in the middle-aged and elderly people in Lishui District of Nanjing. Exposed to air pollutants, men were more susceptible to O3 damage, and women were more susceptible to PM2.5 damage. Reduction of PM2.5 and O3 concentration in the air may have the potential to avoid considerable loss of lives.

“…The Kriging interpolative method, an optimal spatial interpolation technique (Gandhi and Sarkar, 2016), is a widely-used geostatistical method (Lorkowski, 2021;Gao et al, 2021;Meng, 2021;Hurtado et al, 2021) for creating smooth surfaces by interpolating the value of the quantity of interest between points at which it has been measured, based on the distance between those points (MacKenzie et al, 2018). The determination of the interpolated value is not carried out by some arbitrary algorithm, but takes into FIGURE 2 | Sediment cores retrieved from the CYSM zone in April 2011.…”

A Synthesized Study of the Spatiotemporal Evolution of Central Yellow Sea Mud Depositional Processes During the Holocene

The spatial distribution patterns of central Yellow Sea Mud (CYSM) thicknesses and their temporal evolution during the Holocene are here updated using data from 10 new cores, in combination with the previously-published data for 64 cores from this area. Of these 74 cores, 15 exhibit clear AMS 14C dating constraints. Three subareas of mud deposition can be delineated using analyses of spatiotemporal mud thickness distributions and the variations between these. A depocenter subarea, with mud thicknesses >4 m, lies in the northwestern part of the CYSM; the mean sedimentation rate (SR) is relatively high in this subarea, with two high SR stages occurring at ∼6.1–5.4 ka and ∼4–2.5 ka. An adjacent subarea surrounds the depocenter subarea; this subarea has mud thicknesses between 2 and 4 m, and a high mid-Holocene SR which evinces a gradually decreasing trend after 5 ka. A distal periphery subarea lies in the eastern part of the CYSM, with mud thicknesses between 0.5 and −2 m, and a low mean SR that has been generally stable over the last 7 ka. Our results indicate that both sedimentary sources and hydrological dynamics played important roles in the formation of CYSM. The Yellow River may be the principal sedimentary source for CYSM, as mud thickness decreases gradually from northwest to southeast. Different mud subareas appear to be affected by different hydrological dynamics: in the depocenter subarea, oceanic current fronts seem to play an important role in mud deposition, while in the adjacent subarea and the distal periphery subarea, weak tidal currents appear to be the dominant depositional control. The generally decreasing trend in the SR of the adjacent subarea indicate that the East Asian winter monsoon (EAWM) potentially controlled changes in CYSM sedimentary sources after 7 ka.
