“…A similar conclusion was drawn regarding the organic matter with its relation to the soil heavy metals, playing an important role in controlling their levels in soil . Many other workers have shown that both pH and OM play an important role in regulating the bioavailable level of heavy metals in soil . Thus, the present experimental data, showed that the pollution indices are statistically significantly associated with the pH and OM and this finding has led our team to work with more detailed interest and with scrutiny in relation to understanding the role of organic matter in the more accurate assessment of the soil pollution level.…”

“…We also found that other researchers have also studied the relation of pH and OM to soil heavy metals and that their results were in agreement with ours. [30][31][32][33] So, this has been for us an additional impetus that lead us to the further study of the pH and OM relationship with pollution indices.…”

BACKGROUND Experimental data were used to study the impact of pH and organic matter on soil pollution indices, with the view to express them as a function of the above two variables. RESULTS Data were from an experiment performed in a greenhouse using 12 wastewater and sludge treatment combinations in four replications, using Lactuca sative var Longifolia as a test plant. The experimental data were analyzed by means of linear multiple regression analysis, and the equations found were considered as revised forms for the calculation of pollution indices, which could be used as a tool for the assessment of the level of soil pollution by heavy metals. CONCLUSION Tentative critical levels of the pollution indices were established on the basis of the reference revised Index PLIn. However, additional work is necessary, such as calibration of the revised indices on the basis of percentage crop yield loss, towards a more accurate assessment of the heavy metal soil pollution levels. © 2018 Society of Chemical Industry

“…Soil organic matter, represented by humus substances, introduced to soil with natural, organic and organicmineral fertilizers restricts the amount of bioavailable heavy metal forms (Zaniewicz-Bajkowska, 2000; Kwiatkowska-Malina and Maciejewska, 2009). So-ils enriched in organic matter contain a lower amount of phytoavailable fractions of heavy metals (Wo-³oszyk et al, 2005;Kwiatkowska, 2006;Sk³odowski et al, 2006;Kwiatkowska-Malina and Maciejewska, 2011;.…”

Organic matter takes part in all soil processes and influences the physical, chemical and biological properties of soil. The paper presents the analysis of heavy metal contents (Zn, Pb, Cd) in soil and biomass of darnel multifloral (Lolium multiflorum Lam.) cultivated at diverse conditions of soil reaction and organic matter content. A brown coal preparation (Rekulter) was applied as the source of organic matter in autumn 1999 to the studied soil, which was contaminated with cadmium, lead and zinc. The limiting influence of Rekulter on the uptake of heavy metals by darnel multifloral (two cuts of the test plant) was the highest in the case when the largest dose was applied to soil with the highest pH (about 6.0). Bioaccumulation indexes (BI) for Cd, Pb, Zn indicate the mobility and bioavailability of Cd, Pb and Zn in soils. The BI for particular heavy metals were generally low, with the lowest in the case when the largest dose of Rekulter was applied to all cuts of the test plant

“…Only an acidic coal mining soil (pH 3.8; Pb total 32 mg kg −1 ; SOC 3.9%; clay 9%) contained a maximum of 5% of total Pb in fraction I (Marschner et al 2006) which is still well below the Pb amounts found in the pylon soils. In most of the 15 soils investigated by Marschner et al (2006), the Pb amount of fraction IV dominates (mean 36% of total Pb) similar to the urban soil I used in this study, underlining the known high affinity of Pb to sorb to organic matter (Kwiatkowska 2006;Alvarenga et al 2009). Despite similar SOC contents, the pylon soils contain much lower Pb amounts in fraction IV.…”

Red lead (Pb 3 O 4 ) has been used extensively in the past as an anti-corrosion paint for the protection of steel constructions. Prominent examples being some of the 200,000 high-voltage pylons in Germany which have been treated with red lead anti-corrosion paints until about 1970. Through weathering and maintenance work, paint compounds and particles are deposited on the soils beneath these constructions. In the present study, six such "pylon soils" were investigated in order to characterize the plant availability and plant uptake of Pb, Cd, and Zn. For comparison, three urban soils with similar levels of heavy metal contamination were included. One phase extractions with 1 M NH 4 NO 3 , sequential extractions (seven steps), and extractions at different soil pH were used to evaluate the heavy metal binding forms in the soil and availability to plants. Greenhouse experiments were conducted to determine heavy metal uptake by Lolium multiflorum and Lactuca sativa var. crispa in untreated and limed red lead paint contaminated soils. Concentrations of Pb and Zn in the pylon soils were elevated with maximum values of 783 mg Pb kg −1 and 635 Zn mg kg −1 while the soil Cd content was similar to nearby reference soils. The pylon soils were characterized by exceptionally high proportions of NH 4 NO 3 -extractable Pb reaching up to 17% of total Pb. Even if the relatively low pH of the soils is considered (pH 4.3-4.9), this appears to be a specific feature of the red lead contamination since similarly contaminated urban soils have to be acidified to pH 2.5 to achieve a similarly high Pb extractability. The Pb content in L. multiflorum shoots reached maximum values of 73 mg kg −1 after a cultivation time of 4 weeks in pylon soil. Lime amendment reduced the plant uptake of Pb and Zn significantly by up to 91%. But L. sativa var. crispa cultivated on soils limed to neutral pH still contained critical Pb concentrations (up to 0.6 mg kg −1 fresh weight). Possible mechanisms for the exceptionally high plant availability of soil Pb derived from red lead paint are discussed.
