- •
The effect of firecracker burning on PM2.5 characteristics and human health was assessed.
- •
The burning of firecrackers elevated PM2.5 in a short time.
- •
The burning of firecrackers changed the chemical compositions of PM2.5
- •
PM2.5 concentrations differed for various air mass origins.
- •
Lifetime cancer risks of heavy metals (6.54 × 10− 5) obviously exceed the threshold (10− 6).
