What is the association between short-term exposure to fine (PM2.5) and coarse (PM10-2.5) particulate matter and mortality in East Asian cities?
Short-term exposure, a meta-analysis (Environ Pollut 2015, PMID 26340298) — a 10-μg/m³ increase in PM10-2.5 (lag01) was associated with a 0.69% increase in cardiovascular mortality, but this association weakened after adjusting for other pollutants, particularly PM2.5. The abstract for Short-term exposure states no limitations.

Short-term exposure to fine particulate matter (PM2.5) is associated with increased all-cause, cardiovascular, and respiratory mortality in East Asian cities.
The question
What is the association between short-term exposure to fine (PM2.5) and coarse (PM10-2.5) particulate matter and mortality in East Asian cities?
What they tested
The study hypothesized an association between increased concentrations of fine and coarse particulate matter and increased mortality.
How they did it
A two-stage analysis was conducted across 11 East Asian cities. City-specific estimates were generated using a time-series analysis with a generalized additive model (Quasi-Poisson distribution), followed by a meta-analysis to estimate overall effects.
What they found
A 10-μg/m³ increase in PM2.5 (lag01) was associated with a 0.38% increase in all-cause mortality, a 0.96% increase in cardiovascular mortality, and a 1% increase in respiratory mortality. A 10-μg/m³ increase in PM10-2.5 (lag01) was associated with a 0.69% increase in cardiovascular mortality, but this association weakened after adjusting for other pollutants, particularly PM2.5.
| All Causes Mortality | 0.38 | |
|---|---|---|
| Cardiovascular Mortality | 0.96 | |
| Respiratory Mortality | 1 |
This chart shows the percentage increase in different types of mortality associated with a 10-μg/m³ increase in PM2.5 (lag01).
What it means
Increased mortality was associated with increasing concentrations of both PM2.5 and PM10-2.5 across the 11 East Asian cities studied.
Limitations
The abstract does not explicitly state any limitations of the study.
Where the published abstract does not list limitations, we say so rather than inventing them. Read the full paper on PubMed before drawing conclusions.

Personal PM2.5 Air Monitor
Long-term exposure to PM2.5 is one of the most consistently documented environmental risk factors for human disease and premature death. Large cohorts and meta-analyses link higher PM2.5 to increased all-cause and cardiovascular mortality — about 16% and 28% higher per 10 µg/m³ in the Harvard Six Cities extended…
