Description

Technical field

[0001] The present invention involves a device for detecting trace zinc ions, especially a golden label / card and preparation method for fast detection of zinc ions, which belongs to the field of immunology and sanitary inspection. Background technique

[0002] Heavy metals in soil and agricultural products are closely related to human health.Heavy metal pollution mainly refers to the biological toxicity of mercury, chromium, cadmium, lead, and metal arsenic, and also includes toxic heavy metal copper, cobalt, nickel, tin and other metal pollutants.Different metal pollution is different from other types of pollution, and has the characteristics of concealment, long -term and irreversible.With the expansion of cities and the development of large -scale industries, a large number of heavy metals enter the environment, even if the concentration is low, it may cause harm. It will eventually threaten human health through drinking water or biomass and food chains. [000...
