Priority environmental pollutants include polycyclic aromatic hydrocarbons (PAHs). A complete list of toxic PAHs is established by the US EPA, which includes 16 compounds, while some of this group have carcinogenic, mutagenic and teratogenic properties. Therefore, the purpose of this work was to evaluate the content of 16 priority PAHs in roadside dust in the city of Ivanov. The PAH content in dust samples was estimated by HPLC using a FLUORAT-02M fluid analyzer as a detector. It was found that the benz(a)pyrene content in the dust fraction varies from 0.6 (northern part of the city (residential private sector) to 102.3 μg kg (industrial part of the city) with a median and average value of 10.9 and 19.3 μg kg, respectively. A similar situation is observed with the total content of PAHs. Note that the contribution of BP to the amount of carcinogenic PAHs is insignificant and amounts to less than 1%. It was found that in more than half of the sampling points, the proportion of carcinogenic PAHs was 90% of the total content, with most of the points located along the roads. These data are in good agreement with the results of measurements of BaP content in the snow cover on the territory of Ivanovo [1]. The totality of the data obtained made it possible to identify criterial pollutants that must be recommended for monitoring and to determine possible sources of income. |
