Air pollution exposure is linked to an increased risk of stroke. Elevated levels of pollution (carbon monoxide, carbon dioxide, nitrous oxide, sulfur dioxide, coarse particulate matter [PM], and especially fine particulate matter [PM]) cause systemic inflammation after the particles are inhaled and lodge into lung tissue, causing an increased incidence of stroke, hospitalizations for stroke, and stroke mortality. Until air pollution levels are remediated, assessing Air Quality Index (AQI) and following the guidelines to decrease illness from exposure is imperative. AQI levels are reported hourly, identifying ambient PM and ozone levels. When AQI levels are low, the risk of exposure to PM is low. As the AQI increases, there is more risk. It is important to take steps to decrease exposure to PM, especially for those with cardiovascular comorbidities such as diabetes and those with previous stroke events. This is important information for nurses to understand and share with their patients as a risk reduction strategy.

It is well understood that a significant shift away from fossil fuel based transportation is necessary to limit the impacts of the climate crisis. Electric micromobility modes, such as electric scooters and electric bikes, have the potential to offer a lower-emission alternative to journeys made with internal combustion engine vehicles, and such modes of transport are becoming increasingly commonplace on our streets. Although offering advantages such as reduced air pollution and greater personal mobility, the widespread approval and uptake of electric micromobility is not without its challenges.

Bioaugmented slurry technology is a sustainable remediation technology for PAHs-contaminated soil. However, the lack of experimental data on the remediation of complex, actual contaminated soils has hindered the practical application of this technology. This study explored the bioaugmented degradation of PAHs using actual soil slurry with and without the addition of microbial agents in the microscopic world.

The impacts of air pollution, local climate, and urbanization on human health have been well-documented in recent studies. In this study, we combined magnetic resonance imaging (MRI) brain analysis with a questionnaire survey on the local environment in 141 healthy middle-aged men and women. Our findings reveal that a favorable environment is positively correlated with gray matter volume (GMV) in the frontal and occipital lobes, cerebellum, and whole brain, as well as with fractional anisotropy (FA) in the fornix (including the fornix stria terminalis), posterior thalamic radiation (PTR), sagittal stratum (SS), and whole brain.

This study investigated the effectiveness of Racomitrium canescens in the removal of particulate matter (PM) under controlled flow and humidity conditions. PM pollution is a major environmental and public health concern and exposure to PM is linked to various adverse health effects. Conventional PM removal methods, such as filtration and electrostatic precipitation present challenges, including frequent filter replacement and ozone generation.
