Heavy metal detection is important in environmental pollution, mainly referring to metals or metalloids such as mercury, cadmium, chromium, as well as those with corresponding toxicity, such as copper, zinc, nickel, cobalt, tin, etc. It poses hazards to several aspects such as naturalness, toxicity, activity and persistence, biodegradability, bioaccumulation, and additive effects on organisms.
1、 The importance of heavy metal detection in food:
Due to human factors such as mining, exhaust emissions, sewage irrigation, and the use of excessive products, the environment is polluted, and these pollutants can spread to the food products we rely on for survival through different pathways.
2、 Hazards:
Food products contaminated with this will seriously endanger our physical health. After being ingested, there may be symptoms such as nausea, vomiting, abdominal pain, shock, and low blood pressure during the acute phase, and in more severe cases, it can cause stones, cancer, etc.
From this, it can be seen that heavy metal detection is closely related to daily life.
