GIS Analysis of Potential Carcinogenic Factors
Although progress of modern technology and developments of industrialization improve the convenience and quality of our daily life, the pollutants and hazard factors which may be categorized to carcinogens are accompanied by and increase both in magnitude and diversity. Because of limited budget and manpower, it is impractical to monitor all possible hazards all the time, not to mention that the hazards are indefinite or not been well known. However, without a suitable monitor plan, the unperceived hazard will harm significantly to the environment and residents. For the dilemma aforementioned, a methodology which is designated to find probable high risk regions is thus explored in this study to assist decision makers to allocate scarce resources in risk analysis and monitor plans. Public health data, such as prevalence data of cancers, census data, and potential hazard factors which may be carcinogens are collected first and have been digitalized. These hazard factors maplayers are then analyzed with GIS buffer functions to generate potential polluted area maplayers. The potential polluted area maplayers are assessed with the maplayer of cancer prevalence to locate regions with high prevalence. A study case in middle Taiwan is also demonstrated to ensure the accessibility and satisfaction of this methodology
