(2) Endemic disease research. Some chemical elements on the surface are abnormal, such as endemic goiter or cretinism caused by abnormal distribution of iodine, endemic fluorosis caused by excessive distribution of fluorine, Keshan disease caused by abnormal distribution of selenium, and Kaschin-Beck disease caused by abnormal distribution of chemical elements such as sulfur, magnesium and calcium.
(3) Research on public hazards. Regional special diseases mainly caused by environmental pollution, such as "four-day asthma" caused by air pollution in Japan, "Minamata disease" caused by mercury pollution in water and "osteopathy" caused by cadmium pollution in water. These public diseases are new diseases, which cause people's suffering and death in the affected areas. Many problems, such as its pathogenesis, treatment methods, especially its source control, need to be studied and solved.
(4) Environmental pollution causes cancer, teratogenesis, mutation and loss of immune function.
The serious development of contemporary environmental pollution is causing the above-mentioned ecological medical problems. Ecological medical research to solve these problems will contribute to the healthy life of human beings.
