<p><b>OBJECTIVE</b>To study the present situations of lung cancer in Wuhan and to explore the relationship between the potential years of life lost of lung cancer and air pollution, especially vehicle emissions.</p><p><b>METHODS</b>Data gathered between 1986 and 1995 in Wuhan city, including air pollution and tobacco production and data on lung cancer between 1991 and 2000 were collected extensively. Simple Correlation and Grey Relational Analysis were used to analyze the relationship of them.</p><p><b>RESULTS</b>There was a ascending tendency in variance of oxides of nitrogen (NOx). The degree of grey incidence (DGI) between the concentration of air pollutants and the male's or female's potential years of life lost of lung cancer (PYLL) were calculated respectively. In males, the values of DGI were 0.6702, 0.7071, 0.6199 on sulfur dioxide (SO2), NOx, total suspensions (TSP) respectively. In females,the values of DGI were 0.6188, 0.8555, 0.5842 according to the same order as listed above. Significant positive correlation was found between the concentration of NOx and with lung cancer in both males and females by spearman correlation test (rmale = 0.63523, P = 0.0484; rfemale = 0.76396, P = 0.0101).</p><p><b>CONCLUSION</b>With the fast growing speed of the quantity of vehicles, pollution of vehicle emission-caused air pollution posed an important risk factor for lung cancer, despite the fact that tobacco smoking still played the leading role.</p>
