Overview of Detection Methods for Heavy Metal Content in Plastic Track Surface
Plastic runways mainly include EPDM,composite,hybrid,fully plastic,prefabricated and other types.In the production and paving process,heavy metal elements such as lead,chromium,cadmium,mercury,etc.may be introduced.After being inhaled by the human body,it will endanger health.Accurately measuring the content of these heavy metal elements is a key factor in ensuring product quality.At present,there are various methods for detecting heavy metal content in plastic runway surface in China,including atomic absorption spectroscopy,inductively coupled plasma emission spectroscopy,X-ray fluorescence spectroscopy,inductively coupled plasma emission mass spectrometry,atomic fluorescence spectroscopy,polarography,etc.This article reviews the detection principles,characteristics,and applications of these methods.
