[Some psychological characteristics of persons exposed to small-dose methylated mercury].

In the area polluted by the man-caused mercury in the Angara River reservoir, there is fish accumulation of the toxic substance in the quantities exceeding the standard values by 2-4 times. The psychological characteristics of the persons exposed to mercury load due to fish ingestion were studied. A screening survey revealed the high situational and personality anxiety in 33.9 +/- 6.2 and 53.9 +/- 6.2% of the examinees, respectively. Lower logical and abstract thinking abilities were observed in 92.7 +/- 2.8% of the respondents. Poorer attention, significant fatiguability, and distraction were seen. According to the level of mercury in the biosubstrates, a risk group (n = 26) was formed, which was examined in the inpatient setting. The high prevalence of emotional instability and neurotism was revealed. When examined by a psychiatrist, 9 persons were recognized as apparently healthy. It is necessary to continue studies to objectivize the conclusion that small-dose methylmercury affects mental health.

[Some aspects of professional activities and a risk to the health status of aircraft designers]. / Nekotorye aspekty professional'noi deiatel'nosti i risk narusheniia zdorov'ia konstruktorov letatel'nykh apparatov.

Accumulation of a toxic agent (2-4-fold maximum allowable concentrations) was found in the fish caught in the polluted area of the water storage basin of the Angara river. The authors quantified a risk for major pathological syndromes in individuals exposed to mercury on fish ingestion and assayed biosubstrates for the substance. The integral risk of major pathological syndromes in the potentially mercury loaded persons increased by 62.1% with age and only by 17.1% in the control group. In the risk pattern there were risks for neurological diseases, arterial hypertension, coronary heart disease, borderline mental disorders, and endocrine diseases.
