The research activities at the Department are focused on today's topical and socio-economic environment issues. Hygiene issues of the expanding seaside resorts and the impact of resort factors on the organism of different ages and professional groups are being investigated (M. Kazakova). Shift and night work in contemporary forms of work and their impact on natural biological rhythms is another topical issue which has proved its importance within the research themes of the Department (Sn. Solakova).

Hygiene issues related to the training of 6-year-old first-graders are being developed (P. Nikolova, K. Petrova). Extensive research on physical development and acceleration rates of children nowadays, their physical capacity, health status and frequency of obesity have been conducted (K. Petrova).

Since the establishment of the Department of Hygiene, the research work has been targeted at research on the impact of some heavy metals (lead, manganese) on the body and the possibility of their biological prevention. Laboratory constellations for early diagnosis of lead and manganese effects have been developed. The impact of manganese on certain sides of amino acid metabolism and the activity of certain enzymes have been investigated. Principles of preventive nutrition for people, working in professional contact with manganese, have been developed (P. Nikolova). Health status of workers in contact with lead and the possibility of biological prevention have been examined (P. Nikolova, B. Kavaldzhieva L. Dimitrova, V. Nestorova, Yu. Chalakova, T. Georgieva, D Tomov).

For the first time in the country, comprehensive studies on the effects of aluminum on the organisms of workers have been conducted (P. Nikolova, B. Kavaldzhieva L. Dimitrova, V. Nestorova, Iv. Dzhedzhev,  D. Tomov) and specific recommendations for preventive nutrition are being developed (P. Nikolova, B. Kavaldzhieva).

One invention for cytochemical detection of cellular manganese (L. Halacheva, B. Dokov) and two rationalizations - Electron-microscopic demonstration of manganese in erythrocytes and semi-quantitative method for its determining (B. Kavaldzhieva) have been created.
