Most heavy metals have adverse health effects: carcinogenic, mutagenic, teratogenic as well as gonadic, embryonic, nephrotic or neurotoxic effects. Heavy metals are eternal pollutants. They do not decompose, but move from one ecosystem to another. Not only individual heavy metals, but also them are dangerous synergistic action (it is expressed as total soil contamination). Cannalytical laboratory applies ICP-MS (Inductively Coupled Plasma Mass Spectrometry) for fast and precise heavy metal detection and elemental impurity screening.
