The influence of storage containers on hazardous substances of sample was evaluated. Hazardous substances of heavy metal (lead, cadmium, chromium, nickel, cobalt, antimony, zinc and arsenic) were found in synthetic samples detected by inductively coupled plasma optical emission spectroscopy (ICP-OES) in different storage containers. The effect of materials of containers was evaluated by the change of detection value and initial value of hazardous substances. Results showed that the variation of the same type of hazardous substances was different when stored in different containers. Different kinds of materials of container were suitable for different kinds of hazardous substances. The most suitable material was Fluorinated ethylene propylene produced by foreign.
