This atlas shows the relationship between water pollution and cancer in the Huai River Basin in China over the last 30 years. Drawing on a five-year study conducted by the China Centre for Disease Control (CDC), Professor Gonghuan Yang & Dafang Zhuang present a spatial and longitudinal analysis of regular pollution monitoring and disease surveillance data. A review of variation in trends in the causes of death in the Huai River Basin over the past 30 years shows that precisely those areas which were the most seriously polluted for the longest time were the areas with the highest increase in digestive cancer deaths – several times that of the national average increase for the respective cancers. Spatial analysis shows a high level of correspondence between the seriously polluted areas and areas with high mortality from cancer, the most important finding in the atlas.
