Effect of soil contamination with arsenic and application of different substances on the manganese content in plants

Abstract

The aim of the study has been to determine the effect of some substances such as dolomite, loam, compost, pinewood bark, peat, lime, charcoal, natural and synthetic zeolite on reducing the impact of soil contamination with arsenic on the content of manganese in some plant species. The content of manganese in the test plants depended on the degree of soil contamination with arsenic, application of different substances as well as on the plant species and organ. Soil contamination with arsenic caused either an increase or a decrease in the content of manganese in plants depending on a plant species and organ. In the series without soil amending substances, in the arsenic contaminated objects the manganese content decreased in above-ground parts of cocksfoot and swede but increased in above-ground parts and roots of maize and yellow lupine, in roots of cocksfoot and swede and in straw and roots of spring barley. On the other hand, the highest rates of arsenic depressed the content of manganese in roots of cocksfoot, swede and spring barley. Addition of any of the aforementioned substances to contaminated soil changed the content of manganese in the plants. The most unambiguous effect of the different substances was determined in the case of above-ground parts of maize as well as above-ground parts and roots of cocksfoot, in which the manganese content fell down, and in roots of yellow lupine, grain and straw of spring barley, in which the content of manganese rose. Charcoal and loam caused the largest and synthetic zeolite led to the smallest changes in the content of manganese in plants.

Arsenic interaction and bioaccumulation in food crops grown on degraded soil: Effect on plant nutritional components and other dietary qualities

“…Rather, the two plants showed both synergistic and antagonistic effects under As stress. The results were in agreement with the findings of Najmowicz, Wyszkowski, and Ciecko (). They concluded that the effects of As on Mn bioavailability varied from plant to plant.…”

“…The changes in Mg concentrations may be attributed to high stress of As and its binary metal mixture with Cd and Pb. Previously, with increasing As concentration, an increase in Mg contents has been reported in roots and aerial tissues of corn (Najmowicz et al, ). Ca concentrations in the edible tissues of potato and lettuce showed almost similar results, however these results were not consistent with those observed in tomato.…”

Response of maize (Zea mays L.) to soil contamination with copper depending on applied contamination neutralizing substances

“…One possible method which alleviates the harmful effect of heavy metals consists in soil amendment with neutralizing substances (NWACHUKWU, PULFORD 2008) that bind copper into insoluble metal and mineral or metal and organic forms, which under favourable conditions may remain in soil for a long time as harmless compounds (ZOLNOWSKI et al 2009). Such soil amending substances include zeolites, loam, lime, ground tree bark, manure and peat (NWACHUKWU, PULFORD 2008, KOMAREK et al 2009, NAJMOWICZ et al 2010. Methods for immobilization of metals in soil remain the only available and economically viable way to rehabilitate contaminated soils, which enable restoration of biological life and plant cover on degraded land (KARCZEWSKA, KABA£A 2010).…”

Application of sequential analysis with the BCR method in the estimation of effects of chemical remediation of soil polluted with copper

“…peat, lignite, bark, zeolites, clay minerals, etc.) (Najmowicz et al, 2010;Gworek, 2001;Moirou et al, 2001;Hu et al, 2007). Such sorbents act through binding the contaminants present in the soil and thus reduce their migration within the soil environment.…”
