*Joint senior authorship. Background Previous studies have observed the adverse effects of ambient fine particulate matter pollution (PM 2.5 ) on heart failure (HF). However, evidence regarding the impacts of specific PM 2.5 components remains scarce. Methods We included 58 129 patients hospitalised for HF between 2013 and 2017 in 11 cities of Shanxi, China from inpatient discharge database. We evaluated exposure to PM 2.5 and its components ((sulphate (SO 4 2− ), nitrate (NO 3 − ), ammonium (NH 4 + ), organic matter (OM) and black carbon (BC)), along with meteorological factors using bilinear interpolation at each patients’ residential address. We used multivariable logistic and linear regression models to assess the associations of these components with in-hospital case fatality, hospital expenses, and length of hospital stay. Results Increase equivalents to the interquartile range (IQR) in OM (odds ratio (OR) = 1.13; 95% confidence interval (CI) = 1.02, 1.26) and BC (OR = 1.14; 95% CI = 1.02, 1.26) were linked to in-hospital case fatality. Per IQR increments in PM 2.5 , SO 4 2− , NO 3 − , OM, and BC were associated with cost increases of 420.62 (95% CI = 285.75, 555.49), 221.83 (95% CI = 96.95, 346.71), 214.93 (95% CI = 68.66, 361.21), 300.06 (95% CI = 176.96, 423.16), and 303.09 (95% CI = 180.76, 425.42) CNY. Increases of 1 IQR in PM 2.5 , SO 4 2− , OM, and BC were associated with increases in length of hospital stay of 0.10 (95% CI = 0.02, 0.19), 0.09 (95% CI = 0.02, 0.17), 0.10 (95% CI = 0.03, 0.17), and 0.16 (95% CI = 0.08, 0.23) days. Conclusions Our findings suggest that ambient SO 4 2− , OM, and BC might be significant risk factors for HF, emphasising the importance of formulating customised guidelines for the chemical constituents of PM and controlling the emissions of the most dangerous components.

“…Increasing evidence has revealed that particulate matter (PM2.5-10), as a representative air pollutant, can damage the heart and lungs [13,14] and can induce acute myocardial infarction [15]. Exposure to SO 2 , NO 2 and other air pollutants has also been proven to be closely related to morbidity and mortality due to respiratory diseases [16][17][18][19][20]. Previous researches have shown that short-term exposure to O 3 or CO was associated with adverse respiratory outcomes, including acute changes in lung function [21,22], asthma, bronchiectasis, pneumonia and the total number of respiratory diseases [23].…”

Background The influences of air pollution exposure and temperature on respiratory diseases have become major global health concerns. This study investigated the relationship between ambient air pollutant concentrations and temperature in cold industrial cities that have the risk of hospitalization for respiratory diseases. Methods A time-series study was conducted in Changchun, China, from 2015 to 2019 to analyse the number of daily admissions for respiratory diseases, air pollutant concentrations, and meteorological factors. Time-series decomposition was applied to analyse the trend and characteristics of the number of admissions. Generalized additive models and distributed lag nonlinear models were constructed to explore the effects of air pollutant concentrations and temperature on the number of admissions. Results The number of daily admissions showed an increasing trend, and the seasonal fluctuation was obvious, with more daily admissions in winter and spring than in summer and autumn. There were positive and gradually decreasing lag effects of PM10, PM2.5, NO 2 , and CO concentrations on the number of admissions, whereas O 3 showed a J-shaped trend. The results showed that within the 7-day lag period, 0.5°C was the temperature associated with the lowest relative risk of admission due to respiratory disease, and extremely low and high temperatures (<-18°C, >27°C, respectively) increased the risk of hospitalization for respiratory diseases by 8.3% and 12.1%, respectively. Conclusions From 2015 to 2019, respiratory diseases in Changchun showed an increasing trend with obvious seasonality. The increased concentrations of SO 2 , NO 2 , CO, PM2.5, O 3 and PM10 lead to an increased risk of hospitalization for respiratory diseases, with a significant lag effect. Both extreme heat and cold could lead to increases in the risk of admission due to respiratory disease.

“…Burning biomass fuel (including wood, dung, and charcoal) increases the chance of respiratory infections, including pneumonia, tuberculosis, and chronic obstructive pulmonary disease (Fullerton et al, 2008). Sulfur dioxide emissions in particular have been associated with cardiovascular and respiratory mortality (Wang et al, 2018;Cao et al, 2022;Orellano et al, 2021;Hedley et al, 2002). Women are more directly exposed to air pollution because of cultural norms in many countries where women are responsible for most household cooking.…”

An Appropriate Technology Approach for Utilizing Plastic Waste Derived Cooking Fuel to Reduce Indoor Air Pollution from Solid Fuel Cooking

Combating the environmental crisis caused by mismanaged plastic waste is a global challenge, especially in developing regions due to a lack of recycling availability and waste management infrastructure. One way communities can combat this challenge is by using the process of slow pyrolysis to convert plastic waste into liquid cooking fuel. Using this fuel in cookstoves can help combat the public health issue caused by breathing in smoke from a cooking fire. Open fire cooking remains a common means of cooking in the developing world, and long-term exposure to smoke can lead to chronic lung and eye health problems. The burden of these health problems falls disproportionately on women. Our hypothesis is that switching from wood fire cooking to using stoves fueled by liquid fuel produced from waste plastic will have a positive impact on indoor air pollution, including particulate matter, sulfur dioxide, and carbon monoxide. To test this hypothesis, a series of experiments to measure particulate emissions, sulfur dioxide, and carbon monoxide were conducted. Cookstoves similar to those used in households in developing countries were used when conducting experiments. The results of these experiments indicated that polyfuel produces less particulate than fire wood, with an average PM2.5 of 7.7 μg/m<sup>3</sup> compared with fire wood which had a PM2.5 of 325.6 μg/m<sup>3</sup>. Polyfuel also produces no sulfur dioxide emissions. Kerosene, which is a traditional cooking fuel in much of the world, produced sulfur dioxide emissions of 5.2 ppm under the experimental conditions. If implemented globally, the results of this research suggest that converting plastic waste into cooking fuel can not only reduce the amount of plastic waste entering the ecosystem but can also combat the global public health problems caused by open fire cooking.
