Examination is performed on 87 miners from mine for copper production subject to intensive local vibrations with average rate of increase (K) of the norms for the individual octave frequencies 2.4 times for 3 h exposure of the working shift, as well as to intensive noise--113-115 dB/A equivalent level, general dust--23 mg/m3, fine dust--3.5 mg/m3 and fine quartz--0.43 mg/m3. There are data for vibration effect--changes in the cold test, vibration sensoriness, ultra sound sonometry, in all miners. In a significant part of them are established dyslipoproteinemia--increase of triglycerides, total and LDL cholesterol, values beyond reference (mainly above the norm) of 10 electrolytes and microelements in blood serum (blood). An extremely high prevalence of the cases and the days of total morbidity with temporary disability (respectively 189.7 and 2935 per 100), with predominance in its structure of diseases of the central and peripheral nervous systems, hypertension disease, etc. The importance of vibrations for disorder in the metabolic processes in the organism and development of temporary diseases are underlined. |
