The coronavirus (COVID-19) pandemic is infecting the human population, killing people, and destroying livelihoods. This research sought to explore the associations of daily average temperature (AT) and air quality (PM) with the daily new cases of COVID-19 in the top four regions of Spain (Castilla y Leon, Castilla-La Mancha, Catalonia, and Madrid). To this end, the authors employ Pearson correlation, Spearman correlation, and robust panel regressions to quantify the overall co-movement between temperature, air quality, and daily cases of COVID-19 from 29 February to 17 July 2020. Overall empirical results show that temperature may not be a determinant to induce COVID-19 spread in Spain, while the rising temperature may reduce the virus transmission. However, the correlation and regression findings illustrate that air quality may speed up the transmission rate of COVID-19. Our findings are contrary to the earlier studies, which show a significant impact of temperature in raising the COVID-19 spread. The conclusions of this work can serve as an input to mitigate the rapid spread of COVID-19 in Spain and reform policies accordingly.

Background: Children living in communities with lower socioeconomic status and higher minority populations are often disproportionately exposed to particulate matter (PM) compared to children living in other communities.
Objective: We assessed whether adding HEPA filter air cleaners to classrooms with existing HVAC systems reduces indoor air pollution exposure.
Methods: From July 2022 to June 2023, using a block randomized crossover trial of 17 Los Angeles Unified School District elementary schools, classroom PM concentrations were monitored and compared for 99 classrooms with HEPA filter air cleaners and 87 classrooms with non-HEPA filter air cleaners.

Hydrogen sulfide (HS) is a major air pollutant posing a serious threat to both the environment and public health. In this study, a novel nitrogen-rich biocarbon that effectively removes HS was produced from a mixture of sewage sludge and pine sawdust using melamine as nitrogen source. Compared with pristine biocarbons, nitrogen (N)-doped biocarbons possessed an adjustable porosity, e.

Dust aerosols significantly impact climate, human health, and ecosystems, but how land cover (LC) changes influence dust concentrations remains unclear. Here, we applied the Weather Research and Forecasting model coupled with Chemistry (WRF-Chem) to assess the effects of LC changes on dust aerosol concentrations from 2000 to 2020 in northern China. Based on LC data derived from multi-source satellite remote sensing data, we conducted two simulation scenarios: one incorporating actual annual LC changes and another assuming static LC since 2000.

Background: Although the association of short-term ozone and heatwave exposure with cerebrovascular disease has been well documented, it remains largely unknown whether their co-exposure could synergistically trigger ischemic stroke (IS) mortality.
Methods: We performed an individual-level, time-stratified case-crossover analysis utilizing province-wide IS deaths (n =59079) in warm seasons (May-September) during 2016-2019, across Jiangsu, eastern China. Heatwave was defined according to a combination of multiple temperature thresholds (90-97.

Tire wear particles (TWPs) are considered the one of most significant non-exhaust particle emission sources from vehicles. However, there is a lack of research on the emission characteristics of TWPs based on typical driving information. In this work, we used a high-dynamic outside wheel test platform to conduct tire wear tests on multiple types of tires based on a novel test cycle and comprehensively analyzed the differences in their emission characteristics while considering various factors, such as front/rear tire and tire type.
