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.

Contents of heavy metal on agricultural soils have been raised by land applications of sewage sludge and may constitute a hazard to plants, animals and humans. A field experiment was carried out from 1983 to 1987, to evaluate the long-term effect of sewage sludge application, with and without liming, on heavy metal accumulation and availability in a Rhodic Hapludox soil grown with maize (HMD 7974 hybrid). Trials were set up in a completely randomized blocks design with four replications. Each block was split in two bands, one with and another without liming. The sludge was applied in each band at rates: 0, 20, 40, 60 and 80 Mg ha-1 (dry basis) in a single application; and 40, 60 and 80 Mg ha-1 split in two, three and four equal yearly applications, respectively. The soil was sampled for chemical analysis each year after harvest. Soil samples were analysed for Cu, Ni and Zn in extracts obtained with DTPA and Mehlich-3 solutions, and in extracts obtained by digestion with nitric-perchloric acid (total metal contents), using an inductively coupled plasma (ICP) spectrometer. In general, Zn, Cu and Ni concentrations in DTPA and Mehlich-3 extracts increased linearly with sludge application. Total Cu and Zn concentrations increased when sludge was applied, whereas total Ni concentrations were not affected. Both extractants were suitable to evaluate Cu and Zn availability to corn in the soil treated with sewage sludge. Liming reduced the DTPA extractability of Zn. DTPA-extractable Cu concentrations were not significantly affected by liming. Mehlich-3-extractable Cu and Zn concentrations increased with liming. Only DTPA extractant indicated reduction of Ni concentrations in the soil after liming.

Sludge Application

This study, aimed at assessment of the effects of different sewage sludge application rates on heavy metal accumulation in the soil and in sour cherry leaves was carried out in the years 2005–2007. The rates applied were 0.0, 2.5, 5.0, 7.5, 10.0 and 12.5 kg of dry matter per tree. Eighteen uniform one-year-old Kütahya sour cherry trees on Prunus mahaleb rootstock were used. Sewage sludge not only improved soil chemical properties but also resulted in an increase of nutrient content in cherry leaves. Sewage sludge application increased heavy metal content of soils. However, this increase did not exceed the critical values and was not reflected in the leaf contents of heavy metals. The most effective application rate was 7.5 kg per tree. Studies should be continued to evaluate the effects of sewage sludge on vegetative and generative growth, yield and fruit quality parameters.

Sludge Application

The aim of the present study was to evaluate the influence of sewage sludge application on metal accumulation (Cu, Mn, Zn, Cd, Ni, Pb) at maize (Zea Mays L.). It was applied different doses varying from 0-600 kg/ha of sewage sludge associated with mineral fertilization. The results indicated that copper and manganese contents increase with fertilization and rates equivalent to 200 kg N/ha resulted in statistically significant copper content in the maize leaves. The highest accumulation of manganese in the leaves was recorded at the sludge rate equivalent to 300 kg N/ha, meanwhile in the maize kernels after the increasing sludge rate, the manganese content recorded a decreasing tendency. The zinc content in the maize leaves significantly increased with the increasing rate of sludge, starting with a rate equivalent to 200 kg N/ha, sewage sludge application being a promoter of zinc accumulation but without becoming excessive. As concerns the zinc content in the maize kernels, sewage sludge rates higher than 300 kg N/ha resulted in statistically assured increases. The cadmium level in the maize leaves increased directly proportional with the rate applied and the values were statistically assured at rates higher than 200 kg N/ha. The cadmium content in the maize kernels was not affected by the treatments applied, as the very low values obtained were below the detection limit of the analytical method. The lead content in the maize leaves increased under the influence of sludge fertilization, but the accumulation was generally low, all values in leaves being under 10 mg/kg and in kernels under 1 mg/kg Pb.
