Fine particle pollution raises rheumatoid arthritis flare risk and disease activity

Higher ambient PM2.5 exposure was associated with increased rheumatoid arthritis disease activity and a greater likelihood of flares in a four-year South Korean cohort of 1,070 patients. The association appeared stronger with sustained exposure over approximately two weeks or longer, while women and nonsmokers showed more pronounced links between PM2.5 and DAS28-CRP.

Air pollution in pregnancy raises birth risks differently across trimesters

A population-based study of 26,582 live singleton births in Madrid found that associations between NO₂ exposure and adverse birth outcomes varied by pregnancy stage, with key patterns emerging in the first and third trimesters.

Air pollution may worsen rheumatoid arthritis symptoms and flare risk

A novel study shows that exposure to air pollution, especially fine particulate matter like dust, soot, and smoke (PM2.5), is associated with increased disease activity and flare risk in rheumatoid arthritis (RA).

Hydrogen-powered shipping could deliver $284 billion in annual health benefits

Researchers modeled how replacing conventional global shipping fuels with hydrogen could change PM2.5 and ozone pollution, premature mortality, and monetized health benefits. Under complete transition, the model estimated 129,458 fewer premature deaths and US$284 billion in annual monetized health benefits, although some regions experienced increased pollution from hydrogen production or altered ozone chemistry.

Air pollution mixtures linked to higher early preterm birth risk

Pregnancy puts higher oxygen demands on the body, so expectant mothers breathe significantly more air over the course of a day. When air quality is bad, they're also breathing in more harmful pollutants.

Long-term exposure to air pollution linked to increased risk of Parkinson’s disease

Air pollution is a major public health issue, with long-term exposure to fine particulate matter linked with an increased risk of various diseases, including stroke and dementia.

Air pollution may impact genes involved in sperm development

New research presented today at the 42nd Annual Meeting of the European Society of Human Reproduction and Embryology (ESHRE) suggests that exposure to air pollution may impact genes associated with sperm development, raising new questions about male fertility, pregnancy outcomes and offspring health.

Bogotá’s strictest COVID restrictions delivered the clearest air-quality gains

A natural quasi-experiment in Suba, Bogotá, found that more stringent COVID-19 mobility restrictions were associated with larger reductions in PM₁₀ and PM₂.₅ air pollution. The findings suggest targeted traffic and emissions controls could improve urban air quality, although ozone responses were more complex, and the results may not generalize beyond this high-traffic district.

Aircraft emissions could double air pollution deaths by 2040

Scenario-based modeling projects that aviation-related air pollution could drive a major rise in premature deaths by 2040, mainly through PM2.5 and ozone exposure. The study estimates that aircraft emissions caused 33,900 PM2.5-related deaths and 24,600 ozone-related deaths in 2019, with baseline 2040 deaths projected to more than double.

Changing landscapes in Southeast Asia cause thousands of excess deaths

Changes in land-use across Southeast Asia over the past 15 years are worsening air quality and contributing to thousands of excess deaths each year, according to a study led by researchers from Nanyang Technological University, Singapore (NTU Singapore).

Ozone pollution reduces lung benefits of vigorous childhood exercise

Vigorous physical activity promotes lung growth in children, but these benefits are reduced by ozone pollution, according to new research presented at the ATS 2026 International Conference.

Heatwaves above 38 °C significantly spike cardiovascular cases in middle-aged populations

A novel study has revealed a link between extreme weather and the risk of cardiovascular disease among middle-aged and older adults in 157 Chinese cities. Based on a city's climate and location, exposure to extreme heat, cold, and precipitation each increases the risk of heart disease. The findings of the study in the American Journal of Preventive Medicine, published by Elsevier, provide evidence for policymakers across different regions to develop targeted strategies protecting vulnerable populations during extreme climate events.

Climate change could make humidity-driven heat risks more dangerous, study finds

Researchers analyzing 2.46 million ambulance dispatches across 13 Chinese cities found that humidity can intensify the health risks linked to both hot and cold temperatures, with cold-dry and warm-wet conditions posing the greatest risks. Future climate projections suggest compound temperature-humidity events will become more frequent and increasingly shift health burdens toward heat-related events in China.

Rising climate pollution may double air quality alerts in the US

Research reveals climate-driven pollution will surge, increasing air quality alerts and highlighting the need for protective actions, especially for seniors.

Unhealthy air exposure expected to rise sharply in coming decades

New modeling shows almost one in three Americans will routinely breathe air considered unhealthy for sensitive people by the year 2100 due to climate change, a sevenfold increase compared to the turn of the century.

Socioeconomic gaps shape vulnerability to air pollution mortality in Europe

Socioeconomic factors are widely recognized as potential modifiers of the relationship between air pollution and mortality, but the available evidence remains limited.

Canadian wildfire pollution associated with increased stroke severity

Short-term surges in air pollution in New Jersey from the 2023 Canadian wildfires were associated with a higher stroke rate and more serious strokes, according to a preliminary study released March 3, 2026, that will be presented at the American Academy of Neurology's 78th Annual Meeting taking place April 18-22, 2026, in Chicago and online.
