“…The availability of metals in the final compost is the one of the major sources of soil pollution. Heavy metal pollution in the soil is mainly caused by Cu, Ni, Cd, Zn, Cr, and Pb [29,30]. Some heavy metals (Fe, Zn, Ca, and Mg) have been reported as having a bioimportance to human being and plants.…”

The bioavailability and leachability of heavy metals play an important role in the toxicity of heavy metals in the final compost followed by land application. This chapter examines the effects of natural zeolite on bioavailability of heavy metals (Zn, Cu, Mn, Fe, Ni, Pb, Cd, and Cr) in the form of water soluble and diethylenetriaminepentaacetic acid (DTPA) extractable. The toxicity characteristic leaching procedure (TCLP) test was performed to examine the leachability of heavy metals. Water solubility, DTPA extractability, leachability, and most bioavailable fractions were reduced during agitated pile composting (APC) and rotary drum composting (RDC) of water hyacinth with zeolite addition. The addition of the natural zeolite (clinoptilolite) during the composting process led to an increase in Na, Ca, and K concentrations and significantly reduced the water solubility and DTPA and TCLP extractability of heavy metals. The addition of an appropriate amount of natural zeolite during the composting process enhanced the organic matter degradation, thereby increasing the conversion into the most stabilized organic matter and reducing the bioavailability and leachability of heavy metals.

At the present time soils are exposed to increasing anthropogenic impact. The construction of new resorts, roads, pipelines -all of which can increase the soil pollution with heavy metals and oil. One of the most sensitive and informative indicators of the ecological condition of soils is the determination of the activity of the dehydrogenase. As a result, modeling studies found that pollution of chromium, copper, nickel, lead and oil reduces the dehydrogenase activity in all major soils of the Black Sea coast of the Caucasus: southern chernozem, brown typical, brown leached, brown carbonate, brown forest acidic, brown forest acid podzolized, sod-carbonate typical, sodcarbonate leached soils, zheltozem. As a rule, for all investigated heavy metals and oil was a direct relationship between the content in the soil contaminant and the degree of reduction of the biological indicator. The results indicate that the most significant negative impact has chrome. In terms of the negative impact of the change dehydrogenase activity in the studied soils Black Sea coast heavy metal oxides to form the following generalized sequence: Cr > Cu ≥ Ni ≥ Pb. A comparative evaluation of the stability of the dehydrogenase activity to contamination with heavy metals and oil for the main soils of the Black Sea coast of the Caucasus. Heavy metal pollution is least affected dehydrogenase activity typical sod-carbonate soils. For oil pollution on a particular indicator were more stable brown soil Resistance to the chemical contamination of soil depends on the nature and concentrations of pollutants in the soil, as well as the genetic properties of the soil itself.
