Detection principle: (1) After digestion of the sample, all forms of heavy metals (including arsenic, lead, cadmium, chromium, mercury, nickel, iron, aluminum, zinc, manganese, copper, etc.) are converted into ionic forms. After adding relevant detection reagents, color development occurs. Within a certain concentration range, the depth of the solution color is proportional to the content of heavy metals, following the Lambert Beer law. The content value is then measured by instruments and compared with the national standard for agricultural product safety quality and pollution-free vegetable safety requirements to determine the content of heavy metals in vegetable samples.

Lead in crop tissues can lead to a decrease in oxidation, photosynthesis, and fat metabolism intensity, as well as a reduction in water absorption and an increase in oxygen consumption, thereby hindering crop growth and even causing crop death. andSoil heavy metalsPollution has concealment, lag, long-term and irreversible characteristics, making it difficult and time-consuming to control. Therefore, detection should be usedSoil heavy metalsProfessional instruments.
