Abstract-A greenhouse experiment was carried out to determine heavy metal loading capacity, metal mobility, bioavailability, metal-bound forms and pollution effects in the greenhouse soil and uptake of metals by tomato plant following three cultivation years of sewage sludge (SS) application. The effects of SS application on soil metals were compared with the same amount of manure application. Additional to routine soil analysis, several environmental pollution indexes were used to assess the size of possible environmental pollution risks.Successive applications of SS increased both total and available (DTPA, EDTA and HCL extractable) concentrations of Zn, Cu, Ni, Pb and Cd in the greenhouse soil when compared with the manure application. However, the concentration of heavy metals in soil treated with SS were found below the referenced limits. Correlation values between soil metals and plant metal contents in SS and manure applications were considerebly recorded higher in EDTAextractable metals. Relative increases of total and bioavailable metal concentration were recorded higher in SS application than in manure application, and more than that, relative increases of bioavailable metals in SS application were more marked than those of manure application.The most mobile metal fraction in control soil was detected in Zn and the most immobile metal fractions were detected in Ni. Manure and SS incorporation into the greenhouse soil significantly increased the sum of metal concentrations in the mobile fractions. Manure and SS applications increased mobility factor values for all metals. SS application to greenhouse soil caused higher mobility factor values for all metals with the exception of Ni. Lead was detected as the most mobile metal in SS application.'Single-factor pollution index' and 'composite pollution coefficient' of heavy metals in grennhouse soil were not exceeded critical value by the applications. Thus, all of soil samples may be considered as less contaminated by applications and may be acceptable clean. The average 'single-ecological risk index' and 'potential-ecological risk index' values for heavy metals were found below the limits that indicate all metals posed low risk to surrounding ecosystem in short or medium-term. SS application increased 'risk assassion code' values of metals except Ni and, SS has a medium size risk to ecosystem due to their higher toxicity and percentage in the exchangeable and carbonate fraction.Heavy metal concentrations of tomato leaves in SS application were higher than that of manure application, and Pb and Cd contents of tomato fruits in SS application were excessed the limit values for edible vegetables. But no phytotoxicity or no phytotoxic levels of metals were recorded by the application. SS application led to greater transfers of Ni, Pb and Cd metals in plant. However, 'target hazard quato' and 'hazard index' values representing health risks of tomato fruit in all applications were found below the critical value.
