The analysis of trace elements in plant and fish material is necessary for several reasons. This food material can accumulate toxic elements like heavy metals and, thus are intermediate reservoirs through which these toxic elements from soil, water and air can be transferred to living organisms via the food chain.
In plants the presence of abnormally high Br and Cl levels can indicate the illegal application of pesticides or adulterates during the process of food production.
The analysis of trace elements in plant and fish material can be performed with the TXRF spectrometer S2 PICOFOX, which does not require any time-consuming sample digestion with hazardous chemicals.
