This report provides a final summary of the principal findings and key conclusions of a study supported by an HEI grant aimed at "Assessing Adverse Health Effects of Long-Term Exposure to Low Levels of Ambient Air Pollution." It is the second and final report on this topic. The study was designed to advance four critical areas of inquiry and method...

Background Heat warnings are issued in advance of forecast extreme heat events, yet little evidence is available regarding their effectiveness in reducing heat-related illness and death. We estimated the association of heat warnings and advisories (collectively, “alerts”) issued by the United States National Weather Service with all-cause mortality...

Although research indicates health and well-being benefits of greenspace, little is known regarding how greenspace may influence adaptation to health risks from heat, particularly how these risks change over time. Using daily hospitalization rates of Medicare beneficiaries ≥65 years for 2000-2016 in 40 U.S. Northeastern urban counties, we assessed...
Data
Daily 1km PM2.5 data are available on the NASA SEDAC website (https://beta.sedac.ciesin.columbia.edu/data/set/aqdh-pm2-5-concentrations-contiguous-us-1-km-2000-2016). The Daily and Annual PM2.5 Concentrations for the Contiguous United States, 1-km Grids, v1 (2000 - 2016) data set includes predictions of PM2.5 concentrations in grid cells at a res...

Lockdown measures taken in response to the COVID-19 pandemic produced sudden social and economic changes. We examined the extent of air pollution reduction that was attained under these extreme circumstances, whether these reductions occurred everywhere in the US, and the local factors that drove them. Employing counterfactual time series analysis...

NO2 is a combustion byproduct that has been associated with multiple adverse health outcomes. To assess NO2 level with high accuracy, we propose an ensemble model to integrate multiple machine learning algorithms, including neural network, random forest, and gradient boosting, with a variety of predictor variables, including chemical transport mode...

... 19 Recent studies have found strong association between exposure to ultra ne NPs and adverse health effects in humans. 20,21 Due to their unique physical and chemical characteristics, NPs have been the focus of much research owning its industrial applications and environmental toxicity. 22 Despite the interesting results in biomedical applications of cerium and zinc oxide NPs, research on the toxicological pro le of these NPs in a single or combined exposure is still ongoing. ...
... In a study of elderly across the USA, Weinberger et al. (2021) did not find evidence of lower mortality on days with heat warnings; however, the authors did provide a diagram with hypothesized benefits of heat warnings for the sake of reducing heat-health impacts (Fig. 3 of Weinberger et al. 2021). As the results of this study suggest different days would be identified for warnings based on the models (which were built on observed data) as opposed to the actual warnings (based on forecasted data), the accuracy of forecasting both short-term and long-term temperature and air pollution conditions will be critical for developing more targeted warning systems. ...
... Because this association was only found during periods when leaves were on the trees (leaf on months), the authors suggest that shade-related lowering of local ambient temperatures may explain the reduction in fall injuries (Lee et al. 2022). As syncope and heat illness are related to high temperatures, lower ambient temperatures may also reduce outdoor fall injuries occurring secondary to syncope and heat illness (Heo et al. 2021;Horváthová et al. 2021;Kilbourne et al. 1982). The trade-offs between the possibility of increased injuries from trip and fall events related to street trees damaging sidewalks and the occurrence of fewer syncope and heat illness events due to trees reducing local temperatures have not been studied. ...
... The first set of PM 2.5 estimates evaluated here was created by Di et al.; henceforth, the Di estimates. 21 These daily estimates are available at every 1 km × 1 km grid across the continental US from 2000 to 2016, although their 2019 paper only covers accuracy metrics through 2015. Di et al. used a geographically weighted GAM (generalized additive model) ensemble of random forest, gradient boosting, and neural network algorithms. ...
... In many developing countries, due to the high cost of abatement devices/treatments that capture the pollutants such as dioxins and PTEs after the burning of the waste, the medical waste is openly burnt or incinerated without safety control devices, which results in toxic air pollution (Vilella, 2012). Many studies conducted during the COVID-19 pandemic found that poor air quality is possibly correlated to a higher fatality rate ranging from 8% to 21.4% in the U.S. and the Netherlands (Wu et al., 2020). ...
... Another substantial research line is represented by model-based studies. In this context historical measurement data from previous years (or from the pre-lockdown period) are used to run machine learning algorithms (see e.g., Barré et al. 2020;Diémoz et al. 2021;Granella, Reis, Bosetti, & Tavoni 2021;Grange et al. 2021;Keller et al. 2021;Kim, Brunner, & Kuhlmann 2021;Petetin et al. 2020) or to estimate statistical models, as multiple linear regression models (e.g., Bao & Zhang 2020;Dacre, Mortimer, & Neal 2020;Hoermann, Jammoul, Kuenzer, & Stadlober 2021), Generalized Additive Models (e.g., Carlos, Jose M., & Ricardo 2020;EEA 2020;Solberg, Walker, Schneider, & Guerreiro 2021a2021b or Autoregressive Integrated Moving Average models (e.g., Tyagi, Braun, Sabath, Henneman, & Dominici 2020). The fitted model is then used to predict concentrations for 2020 (or for the post-lockdown period) under the BAU (or counterfactual) scenario, i.e., assuming that the lockdown did not take place. ...
... Metrics for three criteria air pollutants were considered in this study: Annual average PM 2.5 and summer seasonal average of daily maximum 8-hour ozone concentrations (2016) were retrieved from the EJSCREEN at the block group level. Annual averages of daily maximum 1-h NO 2 concentrations (2016) were made available by Di et al. [35] at 1 × 1 km 2 resolution. We also considered twenty air toxics and relevant risk indices retrieved from the USEPA NATA estimates; see Text S1 for details. ...
