Soil heavy metal pollution is the most prominent environmental pollution problem in the world. With the expansion of the scale of mining and metallurgy and the use of heavy metal-containing fossil fuels, pesticides, and fertilizers, the situation of heavy metal pollution in soil is still severe. If it cannot be effectively controlled, the scale of pollution may continue to expand. Heavy metal pollution in soil has the characteristics of long residual time, irreversible, easy migration, and high toxicity. Considering the different types and degrees of soil heavy metal pollution, it is necessary to carry out relevant inspections and on-site analysis, which also puts forward higher requirements for the on-site analysis capabilities of testing instruments.
Terra 600 series handheld XRF analyzers can accurately quantitatively analyze the content of various metal and non-metal elements. The instrument is portable and easy to use, and the analysis results are highly reliable, which is suitable for on-site analysis under different conditions.
Traditional analytical methods usually require complicated sample preparation, and the analytical process requires high experimental conditions, and the analytical efficiency and accuracy are affected by method characteristics and sample preparation levels, which are not conducive to field investigation and analysis. Terra 600 series analyzers solve this problem well, and have the following main advantages in specific applications:
l On-site screening, easy to carry,
l Fast analysis in seconds
l No tedious training required
l Superior analytical performance
l Minimum maintenance cost
l innovative function design
l Friendly and efficient operating software
In 2018, in order to implement the Environmental Protection Law of the People's Republic of China, protect soil environmental quality, and control soil pollution risks, the Ministry of Ecology and Environment and the StateThe State Administration of Market Supervision and Administration jointly issued the "Soil Environmental Quality-Agricultural Land Soil Pollution Risk Control Standard (Trial)" (GB15618-2018).
AXR SCIENTIFIC randomly selected soil samples from Heilongjiang, Guangdong, and Qinghai provinces, and used Terra 600 series analyzers for qualitative and quantitative analysis (especially for lead (Pb), arsenic (As), cadmium (Cd), chromium ( Cr), mercury (Hg) five heavy metal pollution elements for analysis):
We compared the test results with the pollution risk screening value and pollution risk control value in GB15618-2018 and found that the cadmium (Cd) element content in soil samples from the Xilin lead-zinc mining area in Yichun, Heilongjiang exceeded the pollution risk control value; Xishan, Yangchun, Guangdong The lead (Pb) element content in soil samples from the tungsten-tin polymetallic mining area exceeded the pollution risk screening value; the heavy metal element content in the water system sediment samples from the Hualong Lashuixia copper-nickel mining area in Haidong, Qinghai was lower than the pollution risk screening value.
The Terra 600 series handheld soil analyzers enable accurate and efficient detection of heavy metals in soil samples. The instrument has the characteristics of portability, fast analysis speed, and strong on-site application ability. By comparing the risk screening value and risk control value standard related to soil pollution, we can effectively evaluate the heavy metal pollution status of the sample collection site, which can be widely used in environmental monitoring, geological analysis, mineral resources survey and other fields.
The Terra 600 series provides the perfect solution for monitoring and risk management of heavy metal contamination in soil. This series includes 600, 600P, 600S three models. We also provide customers with desktop test stand, portable test stand, reverse shield, carbon fiber puncture-proof window, sampling tube, sampling cup, film and other accessories. Customers can choose according to the actual situation. If you need to choose to buy, you can log in to the company's website or inquire for more details.
