Complex evaluation of health state of population residing under combined exposure to noise and chemical risk factors caused by activities of major airport hub

Complex evaluation covered health state of population residing under combined exposure to physical (noise) and chemical (manganese, formaldehyde, phenol, benzene) risk factors caused by airport activities. Findings are unacceptable chronic risks expressed through risk index for development of nervous system diseases (HI=9.45–51.75), respiratory disorders (HQ=2,62–6,95) and immune system ailments (HQ=1,75–4,23). In children, functional disorders of nervous system (parasympathetic type vegetative dystonia) and respiratory organs (chronic disorders of upper respiratory tract) are diagnosed 1,5–1,8 times higher than those in the reference group; over 5% of children aged 4–7 years demonstrate bilateral conductive deafness. Reliable cause-effect relationships were revealed between functional nervous system disorders (parasympathetic type vegetative dystonia, astheno-neurotic syndrome, vascular cephalgia, sleep disorders) and increased serum level of manganese and benzene (proportion of explained dispersion, R²=0,55–0,87, 26,44≤F≥389,54), between respiratory diseases (chronic rhinitis, chronic pharyngitis) and increased serum level of formaldehyde (R²=0,73–0,91; 350,8≤F≥778,3), with high statistic significance (p < 0,0001). For sanitary epidemiologic examination purposes, case-based reasoning for relationships of children health disorders, management decisions, the authors suggested and justified a list of parameters for negative combined impact of risk factors caused by airport hub.
