Heavy metals not only pollute surface water through runoff and leaching, but also enter the human body through the food chain. The accumulation of heavy metals cannot be metabolized by the human body, directly or indirectly endangering human health. Below are several commonly used methods for heavy metal detection.
1. Atomic Fluorescence Spectroscopy
2. Atomic absorption spectroscopy
3. Inductively Coupled Plasma Emission Spectroscopy
4. Laser induced breakdown spectroscopy
5. X-ray fluorescence spectroscopy
Heavy metal detection is a long-term task that requires the development of detection methods towards sensitivity, selectivity, and convenience, constantly introducing new methods to solve new analytical problems encountered. With the establishment of analytical methods and the continuous progress of science, heavy metal detection is gradually moving from simplicity to complexity. It can be foreseen that instruments will develop towards multifunctionality, automation, and miniaturization, and detection accuracy and sensitivity will also be enhanced.
