title: [Effect of electromagnetic fields of natural and anthropogenic origin on the frequency of pathology occurrence in St. Petersburg].
abstract: The effect of man-made electromagnetic fluctuations and strong geomagnetic disturbances on human pathology-data from St. Petersburg (Russia, 1981) is analyzed. The most remarkable effect is the 7-day variation of the ambulance-call data for myocardial infarction, that show a decrease in pathology-rate (70%) during week-ends and public holidays. Results of measurement of man-made electromagnetic fluctuations in the frequency range 0.005-10 Hz in 1991 and 1994 show a big decrease in electromagnetic noise during week-ends. We suggest that very big 7-day variation in infarction rates is connected with the decrease of electromagnetic noise during Saturdays-Sundays. This phenomenon is responsible for the very big 7-day variation in infarction rate. The myocardial infarction rate cleaned up by meteorological and social effects show the increasing by a factor 1.14 during geomagnetic storms.
