Particulate matter research, explained
10 open-access particulate matter studies, each with a flashcard deck and a quiz.
- PM2.5 components and hospital admissions
A 10 μg/m³ rise in two-day PM2.5 was linked to about 1.9% more cardiac emergency admissions in 26 US communities.
- Short-term PM2.5 raises deaths and Parkinson’s admissions
Two-day average PM2.5 is linked to higher all-cause mortality and to hospital admissions for Parkinson’s disease and diabetes among US Medicare enrollees.
- Low PM2.5 still tracks Canadian mortality
In 299,500 Canadians, a 10 μg/m³ rise in PM2.5 was linked to HR 1.26 for non-accidental death even at mean 6.3 μg/m³.
- Traffic PM and nearby roads raised diabetes incidence
In the Heinz Nixdorf Recall cohort, living within 100 m of a busy road and higher total PM10 were associated with more new type 2 diabetes over ~5 years.
- Beijing PM2.5 and influenza-like illness
Beijing PM2.5 averaged 100.66 μg/m³ and tracked higher influenza-like illness mainly in flu season.
- 2012 Colorado wildfire PM raised asthma visits
During a 32-day 2012 fire period, modeled PM2.5 associated with asthma/wheeze and COPD ED visits; cardiovascular associations were largely null.
- PM2.5 lowers lung function in COPD, NO2 in asthma
In a Rome panel, fine particles reduced FVC and FEV1 among COPD patients, NO2 reduced FEV1 among asthmatics, and IHD patients showed no spirometric response.
- PM2.5 oxidative potential modifies heart-attack risk
Same-day PM2.5 raises myocardial-infarction visits more where particles deplete glutathione, and NOx–ozone oxidant capacity adds further risk.
- Saharan dust days worsen coarse-PM mortality
In Rome 2001–2004, coarse PM raised death risk most on Saharan dust days; fine PM effects were not modified by dust.
- Prenatal PM2.5 linked to preterm birth in Puerto Rico
In the PROTECT birth cohort, an IQR rise in pregnancy-average PM2.5 was associated with higher preterm-birth risk among relatively healthy Puerto Rican women.
