Test Result

The presence of heavy metals in waters can be sourced from mining, household, agricultural waste and industrial wastes. Some heavy metals are toxic such as Cu, Hg, and Pb can accumulate in aquatic sediments. Sediments that are contaminated with heavy metals will endanger the organisms that live in them. This research aims to identify the concentrations of heavy metals Cu, Hg, and Pb in sediments in the Batang Ayumi River. This research uses a descriptive exploratory method by conducting a survey in advance. Determination of sampling locations using purposive sampling method at four determined stations. This research uses an Atomic Absorption Spectrophotometer. Data analysis was performed by comparing the test result data with the quality standards issued by the IADC / CEDA. The test results show that the concentration of Cu, Hg and Pb in the sediment has a value smaller than the target level value, so the substance in the sediment is not too dangerous for the environment.

The paper evaluates the presence and content of traces of heavy metals Hg, Pb, Ni, Cd (total forms) from coal and solid combustion products, the degree of transfer and accessibility in the area of influence of a lignite power plant. The content of toxic heavy metals in residues are characterized by RE Meiji [ 1 (Pb and Hg) and REMeij �1 (Ni and Cd) for the filter ash. Pb and Ni content in the soil exceeds normal values, and Pb exceeds and alert value for sensitive soils around the residue deposit (70.20 mg.Kg-1). The degree of accessibility of the metals in plants (TF), reported at the Khan reference value (0.5), indicates a significant bioaccumulation level for the metals: Cd (1.9) and Hg (0.6) inside the deposit; Cd (0.39) at the base of the deposit, Hg (0.8) in the area of the thermal power plant. The trace levels of heavy metals analyzed by GFAAS and CVAAS (Hg), indicates a moderate risk potential for food safety and quality of life in the studied area.

Removal And Recovery

Experiments on the real possibility of employing microorganisms to capture inorganic polluting substances, mainly heavy metals from urban and industrial wastes, are running using bacteria biomass. Many strains of Arthrobacter spp., gram-negative bacteria, diffused in the soil also inacondition of environmental stresses, have been proved to be particulary effective in heavy metal capture (Cd, Cr, Pb, Cu, Zn). The active and passive processes in accumulation of metals by bacteria were studied. Our experiments have been done on fluid biomass and on a membrane both for practical use and for an easy recovery.
