ABSTRACT

Respiratory activity (specified by carbon dioxide release) was tested in soils
polluted with diesel oil, sampled from pots after the end of the growing season.
Carbon dioxide release was determined by the absorption method. The samples collected
from pots were brought to a moisture content of 60% maximum water-holding capacity.
Carbon dioxide emission was determined at three temperatures: 10°C, 15°C
and 20°C. Incubation was conducted in an ST3C60 thermostatic cabinet. The
results obtained from the tests were analysed by ANOVA (F-test) for factorial
designs. Significant differences were determined by Duncan’s test at the
significance level of P = 0.01.


The aim of the paper was to determine the respiratory activity of soils contaminated
with diesel oil. For the soils polluted with diesel oil on which Scots pine grew,
the objects with a zero diesel oil dose had the highest carbon dioxide emission.
The increasing of the petroleum derivative dose caused a decrease in CO2 release.
An inverse relationship was observed for the soils with European beech seedlings,
the highest emission (average from 3 days) was recorded from the soils treated
with the highest diesel oil doses. In analysing the objects devoid of plants,
it was observed that the diesel oil dose had not affected the CO2 emission rate.
The respiratory activity of these soils was at one statistical level, regardless
of the pollution level. The highest carbon dioxide emission was recorded after
1 day of measurement (in both the planted and unplanted objects) and the carbon
dioxide release decreased over time.

Key words: carbon dioxide, soil, fuel, Scots pine, European beech.
