“…PH and conductivity meters were utilized to measure the soil pH and electrical conductivity (EC), respectively [53][54][55]. The diethylene triamine pentaacetic acid (DTPA) technique is employed to determine the concentrations of the heavy metals (Fe, Zn, Cu, Pb, Mn, and Co) utilizing a GBC atomic absorption spectrometer, model 906 AA [56][57][58][59]. The pour plate procedure was used to calculate the total coliform counting in the soil samples [60][61][62].…”

Numerous farmers regularly irrigate their farms with inadequately treated sewage water pumped from the sewage system in the Arab El-Madabegh district of Assiut City, Egypt. According to previous studies, long-term irrigation with partially treated sewage water resulted in significant changes in the physicochemical properties of soil. The principal goals of this study are (1) to infer empirical equations between geoelectrical resistivity measurements and certain biophysicochemical parameters of some soil samples, and (2) to use these empirical equations to calculate the biophysicochemical parameters of the unknown samples for the same location. For this purpose, 27 soil samples at different depth levels (0 to 25, 25 to 60, and 60 to 90 cm) were collected from eleven locations at the sewage station. Physical properties including water content and particle size distribution, chemical properties including soil pH, electrical conductivity (EC), and the heavy metals concentrations, biological properties including total coliform counts, and geoelectrical resistivity measurements were estimated and analyzed for these samples. Electrical resistivity measurements and biophysicochemical properties were cross-correlated using the exponential trend line to fit the cross-correlated data, and the empirical relationships were obtained. These empirical relationships in conjunction with the measured electrical resistivity measurements were used to calculate the biophysicochemical values of the other three random soil samples. The biophysicochemical values of the former three samples were measured by the same normal procedures as 27 samples. Then, the calculated values were correlated with the measured ones. Good correlations between the estimated and the measured values for biophysicochemical features were obtained. Therefore, this method can be employed to calculate the biophysicochemical parameters for any unknown samples that have the same geological conditions for estimating and monitoring soil contamination.

R E S U M OConduziu-se este estudo com o objetivo de avaliar a concentração de metais pesados no solo, provenientes de resíduos orgânicos, bem como a ocorrência de fitotoxicidade de metais em soja. Os metais no solo foram extraídos por ácidos orgânicos, comumente presentes na rizosfera das plantas. A soja foi cultivada sucessivamente, durante oito anos, e recebeu repetidamente, a aplicação dos resíduos de origem urbana, como lodo de esgoto biodigerido (LB) e lodo de esgoto centrifugado (LC), e de origem industrial, como escória de aciaria (E) e a lama cal (LCal). O experimento foi conduzido em Latossolo Vermelho distrófico (Oxisolo) na UNESP, Botucatu, SP, onde recebeu os resíduos nas doses de zero (controle) 2, 4, e 8 Mg ha Bioavailability of metals using organic acids after successive application of residues in soil A B S T R A C T The experiment was conducted in order to evaluate the concentration of heavy metals in the soil, from organic residues, extracted by organic acids commonly present in the rhizosphere of the plants and also the occurrence of heavy metal phytotoxicity problems in soybeans grown successively after the use of waste from urban, such as biodigested (LB) and centrifuged sewage sludge (LC), industrial steel slag (E) and lime mud (LCal) that were applied over a long period of time. The experiment was conducted in a Red distrophic Latosol (Oxisol), at UNESP in Botucatu, SP. It consisted of four types of waste, applied at zero (control), 2, 4 and 8 Mg ha -1 (dry basis) before the soybean sowing, every two years, since 2002 till 2010, totaling four applications. In the depth analysed, 0 to 0.10 m and 0.10 to 0.20 m, it was evident that the residue which added most metals to the soil, the leaves and the soybean grains was the LB, increasing the Ni, Cd, Pb and Zn concentration, while in the treatment where the steel slag (E) was used, Cr was the main metal released in the soil. The application of lime mud (LCal) did not increase the concentration of metals in the soil. The soybean crop showed concentration of Cr, Ni and Zn, exceeding the maximum permitted limit for food grains, when it received LB, especially in the highest dose of 8.

Segundo Basta et al. (2005), a solubilidade e a disponibilidade dos metais pesados provenientes da aplicação de resíduos no solo são go...
