The recognizing of some metals, which have a significant role in the pollution of environments is the focus of attention in hygiene and environmental surveillance. These metals, mainly including copper, zinc, cobalt lead and nickel, usually pollute the environment even though to a little degree and when they exceed a certain degree, they change into toxic pollutants. For this reason, they are referred to as toxic metals. The identification of these metals is carried out in other applications such as pharmacology, toxicology and atmosphere pollutants. In analytic chemistry, the application of classical methods, due to low concentration, (the low cost methods and which need precise measurement instrument) is not applicable in a certain subsctance. As a result, it is necessary to use voltammetric methods. These methods are more exact and more expensive and they need more precise labortart instruments. Since there are several methods (voltammetric methodology), tools (electrodes) and environmental conditions for the test and that working process must be properly directed by intermediate results of test and observation of the results by a chemical expert, the use of an expert system in this case can be extremely useful. This article introduces the implementation of an expert system for supporting the identification of trace metals with low concentration.
