abstract = "Various fractions of particulate matter have been associated with
increased mortality and morbidity. The purpose of our study is to
analyze the associations between concentrations of PM2.5,
PM2.5-10, PM10 and their chemical constituents (soluble ions) with
hospital admissions due to circulatory and respiratory diseases
among the elderly in a medium-sized city in Brazil. A time series
study was conducted using Poisson regression with generalized
additive models adjusted for confounders. Statistically
significant associations were identified between PM10 and PM2.5-10
and respiratory diseases. Risks of hospitalization increased by
23.5% (95% CI: 13.5; 34.3) and 12.8% (95% CI: 6.0; 20.0) per 10
\μg/m3 of PM2.5-10 and PM10, respectively. PM2.5 exhibited a
significant association with circulatory system diseases, with the
risk of hospitalization increasing by 19.6% (95% CI: 6.4; 34.6)
per 10 \μg/m3. Regarding the chemical species; SO4 2-, NO3
-, NH4 + and K+ exhibited specific patterns of risk, relative to
the investigated outcomes. Overall, SO4 2- in PM2.5-10 and K+ in
PM2.5 were associated with increased risk of hospital admissions
due to both types of diseases. The results agree with evidence
indicating that the risks for different health outcomes vary in
relation to the fractions and chemical composition of PM10. Thus,
PM10 speciation studies may contribute to the establishment of
more selective pollution control policies.",
