Environmental and Occupational Short-Term Exposure to Airborne Particles and FEV₁ and FVC in Healthy Adults: A Systematic Review and Meta-Analysis.

ABSTRACT:

Background

No study has compared the respiratory effects of environmental and occupational particulate exposure in healthy adults.

Methods

We estimated, by a systematic review and meta-analysis, the associations between short term exposures to fine particles (PM_2.5 and PM₄) and certain parameters of lung function (FEV₁ and FVC) in healthy adults.

Results

In total, 33 and 14 studies were included in the qualitative synthesis and meta-analyses, respectively. In environmental studies, a 10 µg/m³ increase in PM_2.5 was associated with an FEV₁ reduction of 7.63 mL (95% CI: -10.62 to -4.63 mL). In occupational studies, an increase of 10 µg/m³ in PM₄ was associated with an FEV₁
