Forecasting a risk of occupationally related diseases in workers engaged into titanium-magnesium production

Workers of titanium and magnesium production, under occupational exposure to complex of chemical (chlorine, hydrochloride, sulfur dioxide) and physical factors (industrial noise, work hardiness), have arterial hypertension as occupationally related disease, when length of service over 15 years (EF = 71,5%), and nasopharyngitis for length of service over 10 years (EF = 65%). Arterial hypertension risk is mostly associated with increased industrial noise level (F = 1621; R2 = 0.95; p < 0,001; noise 70,1 dB). Mathematic modelling of nasopharyngitis development probability demonstrated dependence of concentration of chlorine, hydrochloride, sulfur dioxide, chlorine and hydrochloride combination (F = 37-281; R2 = 0,37-0,73; p < 0.001; chlorine 0,63 mg/m³). Complex of parameters (leucocytosis, eosinophilia, increased IgA level), activated cellular immunity (increased CD16+56+, CD3+CD25+) and absolute phagocytosis characterized nonspecific inflammatory reaction, immunity tension as a response to a complex of chemical factors of titanium and magnesium production. Markers of endothelial dysfunction and cardiovascular risk (uric acid, VEGF, homocystein, LDLP) and stress marker (cortisol) demonstrate potential effect of occupational factors on vascular wall, metabolic processes and central nervous system, with involvement of «pituitary - hypothalamus - adrenals» axis. Changes of these parameters in workers with long length of service indicate risk of occupationally related disease on preclinical stage.
