“…(Butcher et al, 1989;Jopony and Young, 1994). For a large-scale investigation spanning the growth regions of entire California, it is imaginable that the properties of soils must have varied region by region and, to a lesser extent, sampling site by sampling site.…”

“…Researches have shown that metal sorption by soils increased with increasing the pH [13], organic matter [14,15], cation exchange capacity [16], and the contents of iron and manganese oxides. However, there is a lack of information concerning the adsorption of sludge-borne heavy metals on different soils [17].…”

To evaluate the influences of sewage sludge-derived organic matters on metal sorption and on the resultant sludge loading estimates, a batch experiment was conducted to compare the sorption of Ni, Cu and Pb in sewage sludge filtrates (1:20 sewage sludge to water) on eight soils and the adsorption of metals in a reference solution which had the same matrix as the sewage sludge filtrate except dissolved organic material (henceforth referred to as reference solution). Metal sorption could be well fitted by linear isotherm and the dissolved organic matter in sludge significantly depressed the sorption (p < 0.01). The main factor controlling sorption of Ni on different soils was dominated by soil cation exchange capacity (CEC) and sorption of Cu and Pb was by soil organic matter (SOM). The parameters obtained from the sorption isotherm equations were then used to estimate sludge loadings into the soils. When the sorption parameters derived from the reference solution were used for calculation, that is the effect of dissolved organic matter was not considered, the calculated safe application rates are approximately 47.8, 51.4, 34.2, 31.3, 21.7, 46.3, 187.1 and 27.6 t-sludge/ha for the Beijing, Jiangxi, Xiamen, Jilin, Guangdong, Wuhan, Gansu and Xinjiang soils, respectively. However, when the sorption parameters derived from the dissolved organo-metallic complexes are used for calculation, the corresponding application rates are reduced to approximately 6.0, 3.4, 1.9, 10.0, 6.3, 3.6, 7.3 and 3.5 t-sludge/ha, respectively. By this study we can get a conclusion that the effect of sewage sludge derived dissolved organic matter on heavy metal sorption and soil properties should be considered in the course of regulating the safe application rates of sewage sludge to soil.

“…Broos et al (2007) also developed a regression model using pH (r 2 adj = 0.73) and CEC (r 2 adj = 0.63) for the SIN assay. Soil pH and CEC have been widely recognized as the most important soil properties determining the partitioning of Pb in soils (Bradham et al, 2006;Buchter et al, 1989;Janssen et al, 1997;Peijnenburg et al, 1999). Buchter et al (1989) found that pH and CEC were significantly correlated with Kp (partition coefficient) values for 15 elements.…”

The influence of soil properties on toxicity threshold values for Pb toward soil microbial processes is poorly recognized. The impact of leaching on the Pb threshold has not been assessed systematically. Lead toxicity was screened in 17 Chinese soils using a substrate-induced nitrification (SIN) assay under both leached and unleached conditions. The effective concentration of added Pb causing 50% inhibition (EC50) ranged from 185 to > 2515 mg/kg soil for leached soil and 130 to >2490 mg/kg soil for unleached soil. These results represented > 13-and >19-fold variations among leached and unleached soils, respectively. Leaching significantly reduced Pb toxicity for 70% of both alkaline and acidic soils tested, with an average leaching factor of 3.0. Soil pH and CEC were the two most useful predictors of Pb toxicity in soils, explaining over 90% of variance in the unleached EC50 value. The relationships established in the present study predicted Pb toxicity within a factor of two of measured values. These relationships between Pb toxicity and soil properties could be used to establish site-specific guidance on Pb toxicity thresholds.
