Migracja zanieczyszczeń ropopochodnych w gruntach piaszczystych na granicy stref aeracji i saturacji
Abstract
Migration of total petroleum hydrocarbon (TPH) contaminations at boundary of aeration and saturation zones in sandy soils.
A b s t r a c t. The paper presents studies results of total petroleum hydrocarbon (TPH) contaminations migration in sandy formations on the post-industrial area in Katowice in aspect their horizontal migration between aeration and saturation zones. In all investigated soil samples were determined mineral oils (>C12), gasoline (C6-C12) and polycyclic aromatic hydrocarbons (PAH) content and were also defined coefficient of filtration. Both mineral oils and gasoline belongs to organic liquids group lighter than water. Researches were supplemented with simulation of ground and underground water contamination state, round investigated area and also migration of petroleum hydrocarbon (TPH) contaminations model in examined grounds. The correlation between seasonal position of underground water level and total petroleum hydrocarbon (TPH) contaminations content in ground vertical profile was also showed. Besides variations of filtration rate in relation to petroleum hydrocarbon (TPH), light non-aqueous phase liquids (LNAPL) contaminations content was presented, as well.
