Samples of the sludge were collected from urban channels in Taiyuan city, and its pollution characteristics of heavy metals were researched. As the emphasis, the distribution regularity of five chemical speciation about Cd, Cr, Zn, Cu, Ni, Pb were analyzed. The results showed that the concentration of Ni, Zn, Cr over standard in various degrees. The residual metal fractions had a higher proportion for all heavy metals. Cd, Zn and Ni were predominantly associated with the carbonates bonded metal fraction and the organics-sulfide bonded metal fraction. Cu, Pb and Cr were predominantly bound to the organics/sulfide and Fe/Mn oxides, but their proportion are different. The bio-transportation index of Zn and Ni are larger than the others. This is the emphasis of heavy metal pollutions control for the local channels.

The greatest pollution earth is facing today is heavy metal pollution. So, there is a necessity to find a remedy to clear up this problem. A study was undergone by isolating the bacteria and fungi from the contaminated soil samples by determining its characteristics to resist heavy metals. Several methods have been determined to control the occurrence of the substances in the environment. Studies have shown that the isolated microbes have shown minimal inhibitory concentration. This can be used as a bioremediation method to drive away from heavy metal pollution as much as possible.

Heavy metal pollution is a serious problem to environment in this time. Mercury is a dangerous wastes that make desecrate environment. So the restoration have to do to make a contaminated soil can reuse safety through fitoremediation process using Kersen. This study to analyze the reductions of heavy metal (Hg) in soil after fitoremediation process. The result of this study was showing that connections between degree reductions of heavy metal (Hg) in soil and adsorptions of Mercury (Hg) in Kersen that is concentration mercury in soil more high reductions than in the soil will following of higher Mercury concentrations in Kersen, in this study showing that adsorptions of Kersen in week – 1 after mercury treatment on a sample is in soil 6,80 ppm, root 1,14 ppm, leaf 0,86 ppm in week - 2 for soil sample is 7,31 ppm, root 3,73 ppm, leaf 4,64 ppm and for the last week in soil is 7,98 ppm, root 0,07ppm and leaf is 0,78 ppm. From that result showing Kersen (Muntingia Calabura L) is a accumulator plant and this plant can using for hyperaccumulation because the value of BCF and TF in day 14 or week – 2 is > 1.
