title: Impacts of land use on spatial distribution of mortality rates of cancers caused by naturally occurring asbestos.
abstract: This study investigated the spatial distributions of mortality rates of six cancers: mesothelioma, lung cancer, intestinal cancer, nasopharyngeal and laryngeal cancer, liver cancer, and stomach cancer in Dayao using Geographic Information Systems. Relationships between the mortality rates of the six cancers and land use patterns were investigated by Pearson Correlation Coefficients. The results indicated that the mortality rates of nasopharyngeal and laryngeal cancer, lung cancer, intestinal cancer, and mesothelioma were significantly associated with outcropped asbestos. Both the proportions of farmland and urban area were positively related to the mortality rates of nasopharyngeal and laryngeal cancer, lung cancer, intestinal cancer, and mesothelioma, and significant negative correlations were found between the proportion of forestland and nasopharyngeal and laryngeal cancer and intestinal cancer. It can be concluded that naturally occurring asbestos may significantly elevate the mortality rates of nasopharyngeal and laryngeal cancer, intestinal cancer, lung cancer, and mesothelioma. Moreover, higher proportions of farmland, urban area, and lower proportions of forested land may elevate the mortality rate of the four cancers.
