Foods such as fruits, vegetables, fish, cereals and oilseeds, baby food will be safer for human consumption in European Union markets. However, foods on the market that contain these metals above the new limits will be able to be sold until the end of February 2022.
Contamination of food with heavy metals beyond the permitted limits may occur:
Cadmium is one of the most powerful carcinogens. The main source of cadmium exposure of the population is tobacco smoke, then the consumption of contaminated food. This metal accumulates in the human body in the bones, liver and kidneys and affects the function of these organs. May cause stomach irritation, vomiting and diarrhea.
Lead is an extremely toxic metal that has negative effects especially on neurodevelopment in children. As early as the 1980s, studies showed an association between lead buildup in the body and a decrease in IQ (IQ). The IARC classifies lead as a high-risk carcinogen (group 2A) that causes anemia, chronic kidney damage and functional diseases of the nervous system.
For the analysis of heavy metals in food, in WESSLING laboratories we use ICP-OES and ICP-MS techniques and two accredited EPA methods.
For determination, the sample solution is properly prepared in a microwave digestion furnace using different types of inorganic acids, hydrogen peroxide. It is spray aerosolized and introduced into the plasma inductively coupled with a stream of argon gas in which the sample components evaporate, atomize and ionize.
!!! We recommend testing prior to the food processing process of water and crop soil for vegetables, fruits and fodder.
