The Influence of Infiltration of Leachate From Landfills on the Changes of Chemical Parameters of the Soil

Gałko G.

Journal of Ecological Engineering

2015

Vol. 16, nr 4

198--205

The article presented the results of geochemical research of clean soil and soil contaminated with the leachate from the landfill. Two types of soil were studied – brown with a stony foundation and loamy. The aim of the research was to compare the impact of leachate infiltration on the changes of chemical parameters of soils and to determine their buffer properties and susceptibility to contamination on this basis. The obtained results showed that the total acidity, mineral alkalinity and chloride content in the studied soils reduced after the contamination with the landfill leachate. While the chloride content, general hardness and general alkalinity increased. It has been found that the effect of infiltration of the landfill leachate was the significant reduction of mineral substances due to their washout of the soil profile. It has also been shown that the studied landfill leachate contained substantial quantities of substances favourable to the plant growth.

Seasonal Changes in Microbial Activity of Brown Soil Fertilised with Dairy Sewage Sludge

Jezierska-Tys S., Frąc M.

Ecological Chemistry and Engineering. A

2009

Vol. 16, nr 5/6

575-582

Respiration actiyity and numbers of chosen group of microorganisms were determined in brown soil fertilised with dairy sewage sludge. Research were carried out in field experiment. The study comparing the effect of fertilisation with dairy sewage sludge and of mineral fertilisation on the populations of selected microbial groups and on soil respiratory actiyity were made. The study showed that dairy sewage sludge introduced in the soil caused similar effect on microbiological characteristics as minerał fertilization.

Celem przeprowadzonych badań byfo porównanie oddziaływania osadu ścieków mleczar i nawożenia mineralnego na liczebność wybranych grup mikroorganizmów i aktywność respiracyjną j brunatnej. Wzbogacenie gleby osadem ścieków mleczarskich wywarło korzystny wpływ na jej równo-mikrobiologiczną w porównaniu z glebą nawożoną mineralnie, o czym świadczy bardziej intensywny rozw większości analizowanych grup drobnoustrojów w glebie z osadem niż nawożonej mineralnie.
