Investigation of Influences of Environment Electromagnetic Field Irradiated by High-Voltage Transmission on the Health of Human and Animals

摘要

Objective: Influences of environment electromagnetic fields (EMF) irradiated by the high-voltage transmission lines(HVTL) on the health of human and animals including the brain, heart, and muscle electrical-informations as well as the memory function of brain in animals are investigated, measured, and inspected. Methods: Epidemiological investigations of hearth cases of 1400 people inhabiting near high-voltage transmission line in Sichuan, Beijing, Hunan, and Jiangxi, etc. and measurements of variation of physiological features of people, who live in domain of high-voltage transmission and around transformer substations relative to those far away from high-voltage transmission systems. The changes of brain, heart, and muscle electrical-informations as well as the memory function of brain are inspected by EGI SYSTEM 200 brain electrical information instrument with 250 channels and multi-channel physiological signal acquisition processing system, respectively. Results: The strengths of electromagnetic field irradiated by the high-voltage transmission lines are depressed with decreasing their height from 7000 V/m and 0.1 G to 300 V/m 0.01 G. The environment electromagnetic fields can result in the memory loss, distracted, high increase in blood fat, significantly increases of chronic diarrhea, anemia, and incidence of hoarseness symptoms, but it can also depress the incidence of leukopenia and thrombocytopenia symptoms. Its influences on the hearth of women are smaller than those of men. Otherwise, the results of measurements of brain, heart, and muscle electrical-informations indicate that EMF of HVTL can change the properties of the images of the brain, heart, and muscle electrical-information of the animals in different degrees. Conclusion: EMF irradiated by HVTL can influence the hearth of human body as well as the brain, heart, and muscle electrical-informations of animals at different degree.
