Recently, the State Council publicly released the "Action Plan for Soil Pollution Prevention and Control" (hereinafter referred to as the "Ten Articles"), which clearly states the need toBy the end of 2018, the area, distribution, and impact of soil pollution on agricultural land on the quality of agricultural products should be identified, and strict control of soil with severe pollution should be emphasized to strictly prohibit the cultivation of edible agricultural products.
The 2013 Hunan "cadmium rice" incident shocked the whole country, and during the same period, rice from multiple provinces in China was found to have excessive cadmium levels. There is no possibility of heavy metal pollution during the harvesting and packaging process of rice, so pollution can only come from the farmland where rice is grown. This incident actually reflects that heavy metal pollution in China's soil is already very serious and urgently needs to be treated. The announcement of the "Ten Measures for Soil Pollution" reflects that the country will increase its efforts to rectify soil pollution at this stage.

The heavy metals that pollute soil mainly include mercury（Hg）、 Elements with significant biological toxicity such as cadmium (Cd), lead (Pb), chromium (Cr), and metalloid arsenic (As), as well as elements with certain toxicity such as zinc (Zn), copper (Cu), and nickel (Ni). Soil contaminated with heavy metals poses significant hazards, not only making soil remediation difficult, but also causing damage to human health. Mercury pollution can cause damage to brain tissue when it reaches a certain level after entering the brain tissue; Cadmium is highly toxic and can accumulate in the human body, mainly in the kidneys, causing functional changes in the urinary system; Lead is a highly toxic heavy metal pollution that is difficult to eliminate once it enters the human body. Its main toxic effects are anemia, neurological dysfunction, and kidney damage. In addition, other heavy metal poisoning can also cause corresponding damage, and some can even quickly lead to death. Therefore, the need to avoid similar incidents of "cadmium rice" from happening again is urgent.

Due to the fact that heavy metal pollution in soil is not easily detected intuitively, it needs to be determined through soil sample analysis, crop testing, and other methods. Therefore, scientific instruments are crucial here. Among existing scientific instruments and equipment, handheldX-ray fluorescence spectrometer has to be said to be a powerful tool for on-site detection of heavy metals in soil. This instrument is specially developed for on-site detection and analysis, and can be used for the detection and analysis of various elements. It has the advantages of convenience, speed, and detection results.

Olympus has a handheld modelX-ray fluorescence spectrometer (XRF) can perform high-precision and highly reliable qualitative and quantitative detection of heavy metal pollutants in soil. This instrument with detector technology ensures that users can quickly analyze all elements of interest and provides a lower detection limit for elements. This solution has been favored by regulatory agencies such as the United States Environmental Protection Agency (EPA) and the United Nations Environment Programme (UNEP).

Preliminary analysis of unknown samples can save a lot of costs before implementing soil remediation. And it can quickly locate and identify polluting elementsDetermine the boundaries of the 'key polluted areas' and draw the polluted areas.

Due to the development of heavy industry in certain regions of our country, environmental pollution has occurred. However, economic development cannot be achieved at the expense of the environment. We believe thatThe introduction of the "Ten Measures for Soil Pollution Control" will definitely increase efforts in the treatment of polluted soil. At the same time, advanced scientific instruments and equipment will be used to assist in pollution control, which can to some extent carry out targeted treatment, accelerate the speed of treatment, and make the treatment effect more obvious. Handheld X-ray fluorescence spectrometer is superior to desktop computers in terms of performance and detection efficiency, especially when it comes to on-site detection. Its compact and portable size makes detection work simpler and easier. With the advancement of science and technology, more high-tech instruments will be developed in pollution control in the future to assist in governance and create an environmentally friendly society.
