Analysis of Poisonous Metals

What Are Poisonous Metals?

Poisonous metals collectively refer to mercury, arsenic, lead, cadmium, tin and so forth, and they cause chronic fatigue, liver/kidney damage, headache, insomnia, irritability, numbness and so forth as they inhibit the functions of essential minerals that are vital nutrients when they enter our bodies.

Poisonous metals are said to be taken in from food, air, tap water, food additives, tobacco and so forth. They can result in serious problems in livestock growth and human health as crops grown on soil polluted with poisonous elements are taken in as food. In addition, some large species of fish such as bluefin tuna and red bream are said to be accumulating mercury and cadmium at high concentrations in the bodies, and recommended daily intake is announced for pregnant women. Analysis of poisonous metals is inevitable in order to ensure food safety.

Regarding soil, Soil Contamination Countermeasures Act took effect in February 2003, requiring the land owners to implement soil tests and measures against pollution when constructing buildings, condos and so forth on old factory sites and so forth suspected to have been polluted with hazardous substances. In recent years, there have been more and more cases of pollution with poisonous metals such as arsenic, lead, and cadmium found in the course of utilization of old factory sites and so forth, leading to increased necessity for analysis and testing of poisonous metals.

Furthermore, soil pollution with poisonous metals contained in industrial waste and so forth have caused a serious environmental issue, and various countries including EU are setting up regulations to reduce the use of poisonous metals contained in products (WEEE & RoHS regulations).
