Abstract
RATIONALE: At main pipeline transport facilities, the entry of harmful chemicals into the air of the working area can negatively affect the body of workers. The absence in the existing regulatory documents of clearly formulated criteria for the selection of specific harmful chemical compounds to control their content, especially if they are a multicomponent mixture, introduces certain difficulties in identifying pollutants in the air of the work area. The presence of criteria will allow the employer to correctly draw up a production program, the frequency of laboratory tests to obtain more objective and reliable information about the potential harmful effects of chemicals on workers and timely take measures to prevent their negative effects. AIM: Justification of the list of harmful substances for analytical monitoring of their content in the air of the working area of main pipeline transport facilities for oil and petroleum products. MATERIAL AND METHODS: Qualitative and quantitative analysis of the air in the working area was carried out at 12 oil pumping stations and 5 oil product pumping stations located in Russia. RESULTS: Using chromatography-mass spectrometry, the composition of the gas-air environment formed as a result of oil evaporation was determined, which made it possible to determine a list of harmful chemicals for further planned analytical monitoring of their content in the air of the working area.CONCLUSION: Sampling should be carried out in places with the highest probability of gas emissions into the air. When transporting oil, it is necessary to establish strict analytical control at workplaces over the content of aliphatic saturated hydrocarbons C2-C10, dihydrosulfide mixed with hydrocarbons, benzene in the air, when pumping petroleum products - benzene, gasoline or kerosene, i.e. depending on the type of petroleum product transported.
