Effect of different substances on some properties of soil contaminated with heating oil

Wyszkowski M., Sivitskaya V.

Journal of Ecological Engineering

2015

Vol. 16, nr 1

62--66

The aim of the study was to determine the effect of the application of different substances (nitrogen, compost, bentonite, zeolite and calcium oxide) to soil on its selected properties after prior contamination with heating oil: 0, 5, 10, 15 and 20 g kg-1 d.m. of soil. Heating oil contamination and the application of different substances had a significant effect on the tested soil properties. In the series without additives, heating oil caused an increase in soil pH and a decrease in hydrolytic acidity, the total exchange bases and cation exchange capacity. Bentonite and calcium oxide had the strongest effect of all the substances on soil properties. They induced a rise in soil pH, an increase in the total exchange bases and cation exchange capacity and a decrease in hydrolytic acidity. The effect of other substances, particularly nitrogen and compost, on the tested soil properties was significantly lower. On the soil contaminated with heating oil, the effect of individual substances on the degree of base saturation was relatively small because it did not exceed 8% in all of the test series.

Effect of Heating Oil and Neutralizing Substances on the Content of Some Trace Elements in Maize (Zea mays L.)

The purpose of the present experiment has been to determine the capability of maize (Zea mays L.) to uptake certain trace elements from soil contaminated with heating oil (0, 5, 10, 15 and 20 g kg–1 soil) after soil amendment with neutralizing substances (nitrogen, compost, bentonite, zeolite and calcium oxide). The study relied on determination of the content of trace metals in plants. Incremental rates of heating oil caused depressed concentrations of copper and zinc, increased accumulation of nickel but did not induce unidirectional changes in the content of iron in maize. Bentonite was more effective than zeolite as a soil amending substance. Bentonite reduced the accumulation of three (copper, zinc, iron) and zeolite – just two (copper and nickel) of the analyzed elements in maize compared with the series without neutralizing substances. Application of calcium oxide and nitrogen to soil, in general, favoured the accumulation of the analyzed elements in aerial organs of maize.

Celem badań było określenie zdolności kukurydzy (Zea mays L.) do pobierania niektórych pierwiastków śladowych z gleby zanieczyszczonej olejem opałowym (0, 5, 10, 15 i 20 g kg–1 gleby) po aplikacji do niej substancji neutralizujących (azotu, kompostu, bentonitu, zeolitu i tlenku wapnia), którą określono na podstawie badań ich zawartości w roślinach. Wzrastające dawki oleju opałowego przyczyniły się do obniżenia zawartości miedzi i cynku, wzrostu nagromadzania niklu i nie wywołały ukierunkowanych zmian w zawartości żelaza w kukurydzy. Bentonit był dodatkiem działającym bardziej korzystnie niż zeolit, gdyż ograniczał akumulację trzech (miedzi, cynku i żelaza) z badanych pierwiastków w kukurydzy, a zeolit tylko dwóch (miedzi i niklu), w porównaniu do serii bez dodatków. Aplikacja tlenku wapnia i azotu do gleby na ogół sprzyjała zwiększeniu nagromadzania badanych pierwiastków w częściach nadziemnych kukurydzy.
