Carbonaceous particulate matter on the lung surface from adults living in Sao Paulo, Brazil.

ABSTRACT:

Objectives

We therefore sought to identify the exposures associated with lung surface in long-term residents of São Paulo, Brazil.

Methods

Lung surface carbon were analyzed in 72 autopsy specimens by image analysis. Smoking history, measured PM10 nearest to the home, distance to main road, and distance-weighted traffic density were used as exposure variables. Data are summarized as median (IQR), and compared by Mann Whitney Test, with correlations done by Spearman's correlation.

Results

There was no association between lung surface and age or gender. There was no statistically significant association in lung surface between smokers and non-smokers 6.74 cm2 (3.47 to 10.02) versus 5.20cm2 (2.29 to 7.54), and there was no significant association between lung surface carb
