The waste of trace metals are led the pollutions of water, soil and air. That’s why the accurate and sensitive identification of amount of trace metals in food samples and environment are gained importance in analytical chemistry because of their toxicity to human health. Besides, the direct determination of trace metals, presented at very low concentration especially in real samples, is difficult. In this content, before determination of trace metals by instrumental methods can be achieved successfully using separation/preconcentration procedures. The different synthesized chelating polymer resin adsorbents are successfully used for the SPE of trace metals. The trace metals, such as Cu, Cr, Co, Mn, Zn and Fe, are necessary for human health, when it has been taken at certain limits. But, the trace metals, such as Hg, Cd, Pb, Ni and As are toxic metals for the human body. About this, there are studies on the determination of trace elements and mineral in food samples and environment. In this study, new methods in the synthesis of (meth)acrylamides and use as a sorbent in the trace metals extraction was identified.

Inverse photopyroelectric (IPPE) spectroscopy, a novel variant among the photothermal spectroscopies, has been used for direct determination of ( Kρc)½ in a variety of food samples. The method appears capable of thermal characterization, and when combined with more mature techniques may prove useful in food products industry and storage.

This paper investigates the determination of seasonable variation of trace metals named Copper, Zinc, Iron, Cadmium, Chromium and Lead set down in the groundwater in and around area of tannery areas of Vellore district. The tanneries discharge untreated tannery effluents, which get mixed with the soil, water of the Palar River, and underground in this area. The determination of metals was performed for the groundwater samples which are collected from adjacent to tannery localities, which bears untreated tannery effluents at pre-monsoon and post-monsoon seasons. The metals might be deposited into the plants and vegetables grown on that agricultural soil, which disturb human health. Somewhat risky amount of trace metals were found in some groundwater samples, especially in the case of in pre-monsoon. All these trace metals were analysed by the Atomic adsorption spectroscopy technique (AAS). These metals contamination in the groundwater is answerable for the support of harmfulness in farming crops and underground water.
