Also cited in this ordinance are mycotoxins, organochlorine compounds, and three heavy metal elements, cadmium, lead and arsenic. 1. Heavy metals are widely present in the environment and can get into our food. While metals are naturally occurring in many foods, they build up in the body and can be responsible for a range of problems in the future. The Japanese Food Hygiene Law prescribes the concentration of cadmium in rice. Accumulation of heavy metals in the food chain can occur by bio-concentration e.g. from water or the food source. Main intake sources of heavy metals are fish and seafood, fruits and vegetables, nuts and cereals. In the case of lead, drinking water is also of major importance. The efficiency and accuracy of the optimized methods were evaluated by analyzing the digests of spiked samples. All the valuable health benefits of fish may suddenly become detrimental if heavy metals store up in their bodies over a long time period [ 14 ]. You understand that prolonged trace exposure to heavy metals such as arsenic (As), cadmium (Cd), chromium (Cr), lead (Pb), mercury (Hg), and thallium (Tl), via the food, beverages and drinking water we consume can cause serious health risks.
