YANAGI, Yoshio; ASSUNCAO, João Vicente de and BARROZO, Ligia Vizeu. The impact of atmospheric particulate matter on cancer incidence and mortality in the city of São Paulo, Brazil. Cad. Saúde Pública [online]. 2012, vol.28, n.9, pp.1737-1748. ISSN 1678-4464. http://dx.doi.org/10.1590/S0102-311X2012000900012.
This study aimed to verify the impact of inhalable particulate matter (PM10) on cancer incidence and mortality in the city of São Paulo, Brazil. Statistical techniques were used to investigate the relationship between PM10 on cancer incidence and mortality in selected districts. For some types of cancer (skin, lung, thyroid, larynx, and bladder) and some periods, the correlation coefficients ranged from 0.60 to 0.80 for incidence. Lung cancer mortality showed more correlations during the overall period. Spatial analysis showed that districts distant from the city center showed higher than expected relative risk, depending on the type of cancer. According to the study, urban PM10 can contribute to increased incidence of some cancers and may also contribute to increased cancer mortality. The results highlight the need to adopt measures to reduce atmospheric PM10 levels and the importance of their continuous monitoring.
