Lead (Pb) behavior was studied in soil treated twice with sewage sludge contaminated with lead at interval of 18 months. Soil samples received five different treatments: three with lead [0 (reference); 2,500; 5,000 mug g-1] and two with a mixture of lead and cadmium (interferer) (2,500 + 2,500 and 5,000 + 5,000 mug g-1, respectively). Vases containing treated soil were cultivated with maize in a greenhouse for 75 days. Pb was extracted using nitric perchloric digestion and analyzed by atomic absorption spectroscopy. The soil, containing sewage sludge contaminated by lead presented a higher concentration of Pb. The metal concentration remained constant in all treatments at 20-60 cm depth. No absorption of Pb by the plants was detected.

Sludge Application

The use of sewage sludge on vegetable gardens is a public health concern. A growth chamber experiment was employed to investigate the effect of sewage sludge application on the copper, zinc, lead and cadmium content of lettuce, carrot and pea crops. No yield reduction or other toxicity symptoms were noted, although tissue levels of several metals were elevated. There were small increases in copper in the three vegetables, but zinc and cadmium increased considerably with sludge application. The higher Zn levels present no problem, but the higher Cd levels are undesirable. Cadmium uptake by vegetables and the increased dietary intake of Cd should be considered when sewage sludge is used on vegetable gardens.

Cadmium And Lead

In 2008 and 2009, studies made contents of cadmium and lead in the soil and their uptake by non-traditional plants were studied in a small-plot trial. At the same time also the effect of bio-algeen preparations on phytoextraction of heavy metals by these plants was investigated. Experimental plots were established on the reclaimed land after closing down mining operations in the town of Žacléř (North-East Bohemia) where a layer of sewage sludge from a wastewater treatment plant 0.6–0.8 m thick was subsequently applied. The locality is situated in the altitude of 612 m, its average annual temperature is about 6.8 °C and the mean annual precipitations are 857 mm. Analyses revealed higher concentrations of heavy metals in the applied sewage sludge. The average concentrations of lead and cadmium were 180 mg . kg−1 and 6.89 mg . kg−1, respectively. The experiment had two variants: Variant 1 – sewage sludge without any other substances, and Variant 2 – sewage sludge + bio-algeen preparations (B. A. S-90 or B. A. Root Concentrate). To find the most suitable plant species for the phytoextraction of cadmium and lead, the following non-traditional plants were cultivated in both variants: fodder mallow (Malva verticillata L.), rye (Secale cereale L. var. multicaule METZG. ex ALEF.) and white sweet clover (Melilotus alba MEDIC.). The highest accumulation of cadmium and lead in the aboveground biomass was found out in rye, viz 14.89 mg . kg−1 DM and 14.89 mg . kg−1 DM of Cd and Pb, respectively., As compared with other plants under study, white sweet clover exhibited the significantly lowest capability to extract both heavy metals from soil (viz 0.22 and 3.20 mg . kg−1 DM of Cd and Pb, respectively). A positive effect of bio-algeen on phytoextraction of cadmium and lead was evident in all plants. The highest yield of aboveground biomass was recorded on the plot with white sweet clover with added alginate (496 g . m−2). Of plants under study, the fodder mallow seems to be the most suitable crop for the phytoextraction of both metals (0.35 and 5.87 mg . m−2 of Cd and Pb, respectively).

Abstract The effect of addition of different materials, i.e. sludge, ash and peat, as well as different doses of mixtures of ash and sludge and ash peat, on the total content of heavy metals (Cr, Zn, Pb, Cu, Cd, Ni) and their fractions was studied. Application of municipal sewage sludge, ash-sludge and ash-peat mixtures in the experiment caused a gradual increase in the content of studied heavy metals in soil. The ash was characterized by a low content of heavy metals as compared to municipal sewage sludge. After application of peat and its mixtures with ash a decrease of content of heavy metals was observed, and when the peat was used alone the greatest increase in the organic C content in the substrate could be seen. Distribution of heavy metals in the fractions separated in different combinations shows large variations, depending on the tested metal and the studied variant. Chromium, zinc, lead, and cadmium have been accumulated mainly in the residual fraction (FV), and most of the copper and nickel have been specifically bound with organic matter (FIV). It has been found that the alkaline materials application to the soil decreased the solubility of most heavy metals, which results in a limitation of their uptake by plants. Chromium and copper were an exception, since their solubility increased with the alkalinity of the substrate. An exception was chromium and copper, which solubility increased with the alkalinity of the substrate.
