Key Points

This research aims to investigate how exposure to air pollution correlates with 1-hydroxypyrene levels in the lungs.
Measured 1-hydroxypyrene levels in bronchial lavage samples from 80 patients.
Analyzed the correlation between particulate matter and 1-hydroxypyrene levels.
Conducted multivariable analysis to determine factors influencing 1-hydroxypyrene levels.
A significant positive correlation between PM10 levels and 1-hydroxypyrene levels (r=0.32, p=0.002).
Higher 1-hydroxypyrene levels found in those frying food (0.064 vs. 0.038 µg/L, p=0.004).
Multivariable analysis indicates animal husbandry (β=0.353, p=0.001) and frying practices (β=0.311, p=0.003) as key determinants of 1-hydroxypyrene levels.

Implication

Shows higher 1-hydroxypyrene levels in individuals exposed to air pollution, suggesting occupational hazards.
