Correlation or Causation: Unraveling the Relationship between PM2.5 Air Pollution and COVID-19 Spread Across the United States

Journal of Environmental Science and Economics, Год журнала: 2024, Номер 3(1), С. 27 - 41

Опубликована: Фев. 17, 2024

Numerous studies have examined the potential connection between air pollution, particularly PM2.5, and incidence of COVID-19 cases during pandemic. While several demonstrated a strong correlation, caution is advised as correlation does not imply causation. To address this concern, our two-year observational study employs comprehensive approach that utilizes large sample size draws on temporal spatial data across United States, surpassing limitations previous restricted to specific locations. Through rigorous regression analyses, we control for confounding factors. Air pollution data, crucial component study, has been sourced from States Environmental Protection Agency (EPA). Additionally, case extracted Center Systems Science Engineering (CSSE) at Johns Hopkins University, providing robust widely recognized dataset analyses. Notably, significant exists population (r=0.98, p-value <0.01), confirmed by multivariate analysis, suggesting influence population. It emphasize automatically direct cause-and-effect relationship. Moreover, minimize impact population, employ rates (COVID-19 cases/population States), demonstrating rate independent PM2.5 infection correlated with density, implying population's more likely due probability rather than being cause. In summary, while many report cases, factors like density necessitates further investigation establish definitive causal conclusion,

Indirect Effects of PM_2.5&nbsp;Exposure on COVID-19 Mortality in Greater Jakarta, Indonesia: An Ecological Study

Annals of Global Health, Год журнала: 2024, Номер 90(1), С. 34 - 34

Опубликована: Май 27, 2024

Air pollution, including PM2.5, was suggested as one of the primary contributors to COVID-19 fatalities worldwide. Jakarta, capital city Indonesia, recognized ten most polluted cities globally. Additionally, incidence in Jakarta surpasses that all other provinces Indonesia. However, no study has investigated correlation between PM2.5 concentration and fatality Jakarta. To investigate short-term long-term exposure mortality Greater area. An ecological time-trend implemented. The data ambient obtained from Nafas Indonesia National Institute for Aeronautics Space (LAPAN)/National Research Innovation Agency (BRIN). daily death City's Health Office. Our unveiled an intriguing pattern: while showed a negative with mortality, suggesting it might not be sole factor causing fatalities, demonstrated positive correlation. This suggests is more strongly influenced by prolonged rather than alone. Specifically, our regression analysis estimate 50 µg/m3 increase average could lead 11.9% rise rate. research, conducted areas worldwide, offers compelling evidence regarding influence on rates. It emphasizes importance recognizing air pollution critical risk severity viral respiratory infections.

Temporal Evolution of PM2.5 Levels Related to COVID-19 Mortality in Europe for the Early-2020 to End-2022 Period

Опубликована: Июнь 20, 2023

Rationale: The possible effect of Particulate Matter (PM10 and PM2.5 diameter 10 2.5 µm respectively) levels on Covid-19 mortality is now well established. However, time-evolution according to has been scarcely investigated. Aim: To understand this relationship at the European level for period 2020 (beginning) - 2022 (end). Methods: 16 representative locations in Europe (81 million people) with heterogeneous (µg.m-3), from low high. were assessed by various methods, was reported Johns Hopkins University. Results: trend vs. varied among locations. Overall, estimated mean value a 40±20% increase per 1 µg.m-3 increase. stronger positive gradient PM peak, mortality. Exposure several peaks during about 2-month main contributor increases. Conclusion: Our data confirm temporal relation between exposure mortality, considering integration-time pollution events. Number-concentrations should be used future rather than mass-concentrations (µg.m-3) consideration composition better explain finding.

Calibration of DustTrak and Low-Cost Sensors and Their Application for Assessment of Inhalation Exposures to Traffic-Related PM2.5 and PM1 in Ho Chi Minh City

Atmosphere, Год журнала: 2023, Номер 14(10), С. 1504 - 1504

Опубликована: Сен. 28, 2023

The in-traffic microenvironment can enhance personal exposure to fine particulate matter (PM). With this study, we aimed calibrate a DustTrak instrument (DustTrak 8533 DRX Aerosol Monitor, TSI Incorporated, Shoreview, MN, USA) and low-cost sensors (AS-LUNG-P sensors) then assess inhalation PM2.5 PM1 for different commuters in central areas of Ho Chi Minh City (HCM). were calibrated using gravimetric method under side-by-side conditions. Relationships between the signals PM concentrations measured by identified simple linear regression models (R2 = 0.998, p-value < 0.05) 0.989, 0.05). Meanwhile, determined AS-LUNG-P correlated two-segmented regressions. To obtain corresponding two-segment equations, response was compared with corrected data. coefficient variation (CV) evaluated all smaller than 10%, indicating that data applicable particle assessment. For assessment, results showed open transport modes, such as bikes, motorbikes, walking, exposed more those closed modes (e.g., cars). Specifically, bicyclists had highest inhaled doses among groups. levels morning higher afternoon. Additionally, rapidly increased when passing through intersections major roads moderately decreased surgical facemasks.

Frontiers in Public Health, Год журнала: 2024, Номер 12

Опубликована: Июль 18, 2024

Background Many respiratory viruses and their associated diseases are sensitive to meteorological factors. For SARS-CoV-2 COVID-19, evidence on this sensitivity is inconsistent. Understanding the influence of factors transmission COVID-19 epidemiology can help improve pandemic preparedness. Objectives This review aimed examine recent about relation between SARS-CoV-2/COVID-19. Methods We conducted a global scoping peer-reviewed studies published from January 2020 up 2023 associations temperature, solar radiation, precipitation, humidity, wind speed, atmospheric pressure Results From 9,156 initial records, we included 474 relevant studies. Experimental provided consistent that higher temperatures radiation negatively affect virus viability. Studies (epidemiology) were mostly observational less evidence. Several considered interactions or other variables such as demographics air pollution. None publications all determinants holistically. Discussion The association short-term SARS-CoV-2/COVID-19 dynamics complex. Interactions environmental social components need further consideration. A more integrated research approach provide valuable insights predict with potential.
