Tetrachlorethylene at room temperature is a non-flammable liquid. It is easy to evaporate into the air, with a stimulus, sweet smell. Exposed to very high concentrations of PCE can cause dizziness, headache, drowsiness, confusion, nausea, difficulty speaking and walking, unconsciousness, and death. PCE is stored as fat in the body in the use of tetrachlorethylene, and is slowly released into the blood, tetrachlorethylene in the weeks after the severe exposure can be detected in the breath. Most of the PCE will enter the water or soil, and then evaporated into the air. Some microbes can break down the soil or groundwater PCE. In air, tetrachlorethylene is decomposed sunlight for other chemicals, or by precipitation and then back to the soil and water. Analog biological functions inorganic compound containing a metal element bioinorganic compounds often can be used to simulate Jinan tetrachlorethylene, Bioinorganic chemistry of such compounds known as a relatively simple model compound metal complex or the like. Structural features of model compounds often have been simulated system or have some relevant biological activity. By studying the model compounds, often to understand the complex relationship between the structure and its function between the simulated system. For example, once the synthesis of a series of fence-style, hat, tails basic heme, they do not have the peptide chain, but it can be like hemoglobin, myoglobin, like reversibly bind and release oxygen molecules. By studying the model compounds, understand heme must exist in the hydrophobic environment tetrachlorethylene offer, steric hindrance around is to ensure that hemoglobin, myoglobin, an oxygen molecule reversible binding conditions, of which the divalent iron must not be oxidation of trivalent necessary structural factors. Again, through the structure and properties of a series of copper peptide complex compound, learned the copper atoms surrounding blue copper proteins have distorted tetrahedral coordination, so that the blue copper proteins with significant reduction of the blue and high potential. The total difference between the analog system and the natural system, with the results of the analog system described must be taken when the structure, function and mechanism of the natural system.
