[0031] According to specific embodiments provided by the present invention, the present invention discloses the following technical effects:

[0032] This invention provides a heavy metal detection system that utilizes a heavy metal detection sensor to rapidly detect whether heavy metals exceed the standard in a test sample. An oscillation module ensures uniform concentration of the test sample within the test chamber.
