The minimization of impact of oil pollution on soils in the area of railways using glauconite

[摘要] The analysis of ecological hazards on soil pollution by oil products has been provided in the impact zone of the railway. The results of oil product migration in soils in the area of influence on section Lviv–Khodoriv are given. To study this problem, a method was used to take soil samples according to the standard DSTU ISO 10381-4: 2005. To determine the content of petroleum products used the method MVV No. 081/12-0116-03 Pochvy. Based on the results of the study it was found that contamination with petroleum products in the study area exceeds the norm in the area of influence of the railway at a distance of 5 to –50 m on average 3.5 times. It is proposed to make management decisions to prevent violations of the sanitary protection zone of the railway and the placement of agricultural plots on it. For rehabilitation of contaminated soils, it is advisable to use a natural sorbent – glauconite, which is widespread in the bowels of Ukraine. The adsorption capacity of glauconite relative to diesel fuel has been experimentally established. According to our experiments it is proved the high efficiency of the proposed sorbent, which is 90%. Therefore, in the future it is necessary to periodically monitor the condition of the soil in the area to prevent pollution. This study proves that this practice is necessary.
