The article presents the results of a study of the toxicity of fire-resistant turbine oil «Turbomas «, a derivative of diphenyl-(n-tert-butylphenyl phosphate). According to toxicity parameters, «Turbomas» oil is characterized as a low-toxic compound, does not have neuroparalytic action, exhibits mild cumulative properties, does not irritate the skin and mucous membranes, penetrates intact skin,

The paper presents the results of a study on the possibility of toxic effects developing in contact with the antitumor drug – lysomustine - to assess the health risk in the manufacture of the finished dosage form and its use. The work was performed on 40 outbred rats, 40 guinea pigs and 114 outbred mice. The experimental study has showed that lysomustine does not irritate intact skin, is not a potential allergen, has no skin-resorptive effect, does not cause reproductive disorders. The drug reveales mutagenic properties inherent in many cytostatics, representatives of the class of N-nitrosoalkylureas. The research results allow to conclude that the presence of the drug in the air of industrial premises and on the skin of workers in its manufacture and use of the finished dosage form is unacceptable.

The paper presents the results of assessing the toxicity and danger of the development of neuroparalytic effect of fire-resistant turbine oils «Turbomas», «T-94» and «T-95» based on triaryl phosphates. According to the toxicity parameters, the studied oils are low-toxic substances, exhibit weakly expressed cumulative properties, do not irritate the skin and mucous membranes, penetrate through intact skin, and increase the activity of microsomal enzymes, when injected into the stomach and abdominal cavity. The study of the neuroparalytic action of oils «Turbomas», «T-94» and «T-95» did not reveal the presence of clinical and morphological signs of disorders of the neuromuscular apparatus in animals, which makes it possible to exclude the possibility of neuroparalytic action in persons in contact with the studied oils.

When examining the population exposed to organic and inorganic compounds of mercury, a comprehensive approach is proposed, including chemical monitoring of environmental objects, biological monitoring, clinical examination of persons exposed to mercury, identification of high-risk groups.
