Neutron activation analysis was used in a comprehensive study of the surface layer of soils, drinking (tap) water, and the hair of residents of the city of Salavat as an index of the anthropogenic load on the human body. The surface soil layer showed an increased amount of such elements as arsenic, calcium, cobalt, chromium, nickel, thorium, uranium, zinc, which can be used in organic synthesis. The contents of iron, manganese, and nickel in the tap water were found to be above permissible limits. Analysis of the hair of city residents showed risk groups for cardiovascular disease (74%) and gastrointestinal disease (71%). Such high levels indicate poor ecological conditions.

中子活化分析被用于对土壤表层、饮用水（自来水）和 Salavat 市居民头发的综合研究，作为人体负荷的指标。表层土壤中砷、钙、钴、铬、镍、钍、铀、锌等元素含量增加，可用于有机合成。发现自来水中铁、锰和镍的含量超过了允许的限度。对城市居民头发的分析显示心血管疾病（74%）和胃肠道疾病（71%）的高危人群。如此高的水平表明生态条件差。
