Normative content of oil products and phenols in wastewaters of the Northern railway treatment facilities

Abstract

The purpose of the work was to compare the functional state of the Northern railway employees (SZD) with the indicators of petroleum products and phenols in wastewater. We investigated the level of petroleum products and in samples of waste water of phenols (total 150 samples) twenty companies of the polygon of the SZD using the fluid analyzer «Fluorat 02-2M» fluorimetric method. The functional state (arterial pressure (BP), body mass index, adaptive potential of blood circulation) was determined in 150 specialists of nineteen enterprises of the entire range by conventional methods. Results. No exceedances of the recommended levels of oil products and phenols in wastewater were detected at all enterprises of the Russian Railways. However, the level of oil fluctuated significantly (ANOVA, p= 0.01): the minimum value detected at the station s of the city of Y aroslavl , the settlement of Vychegodskiy, Kotlas and the village of Kuloy , and elevated – stations, Inta, Vorkuta and the settlement of Konosha. The phenols level differed between the stations of SZD (p= 0.01): the minimum values were marked at the station Yaroslavl-Main, and the maximum – at the station Sosnogorsk.
