Abstract:
This paper presents the analysis of the environment above the soils polluted with hydrocarbons and also after different treatments with natural absorbent and organic solutions. This study aims to highlight the bioremediation effect of natural muscles absorbing Sphagnum, accelerated by organic products such as biodegradable detergent LDC (based on coconut oil) and Petrolsynth (based on degrading enzymes and microorganisms). The gaseous emissions are studied using the Gasmet DX-Series Fourier Transform Gas Analyzer (FTIR) and the Calcmet software, which is connected to the former.
Initially, we analyzed the atmosphere above the soil samples polluted with two types of petroleum hydrocarbons: original engine oil and used engine oil from car service. Next, we applied various bioremediation treatments based on Sphagnum moss and biodegradable detergent LDC or Petrolsynth. Atmosphere monitoring above the samples was recorded weekly.
The results show a regular decrease close to zero in the concentration of harmful substances such as benzene and methanol after soil bioremediation treatment.
Experimental data highlight differences between the atmosphere above polluted soils before and after they have been treated with organic solutions and moss. This study is complementary to the one in which the impact of bioremediation substances is evaluated directly in soil samples, by UV-VIS spectrometry. The measurements highlight the correlations between the time required to clean the soil of hydrocarbons by applying these treatments and the time of removal of pollutants from the environment.
