Environment pollutants are found here and there in developing countries and these contaminations affect the environment adversely. A few remediation of pollution which includes incineration which is the waste treatment process that involves the combustion of organic substances contained in waste material, the waste handling practices, the recycling resource recovery, the avoidance and reduction methods, the adsorption based on nanotechnology and the bioremediation technology which appears as a cost-effective and environmental friendly approach for cleanup. Recently researches shows that various chemicals (VOCs, BTEX, heavy metals) that might be delivered into the air or water can cause unfriendly health effects which was analyzed based on sample treatments (solid phase extraction: SPE, the liquid-liquid microextraction: LLME, the magnetic solid phase extraction: MSPE) and instruments such as ET-AAS, F-AAS and GC-FID methods. The related weight of disease can be substantial, and interest in research on health effects and intervention in explicit populations and openness circumstances is significant for the development of control systems. Pollution control and determination is thusly a significant segment of disease control, and health experts and analytical chemistry specialists need to foster associations with different areas to recognize and carry out need interventions.

Background : A new method has been developed for the determination of food dye tartrazine in soft drinks. Tartrazine is determined by hyphenated technique Ultra Performance Liquid Chromatography coupled with Mass spectrometry. The solid-phase extraction was used for the extraction of tartrazine. Methods: For the LC-MS analysis of tartrazine acetonitrile, water (80:20) was used as a mobile phase whereas, the C-18 column was selected as the stationary phase. The chromatographic run was allowed for 1 min. The adsorbent of the solid-phase extraction was synthesized from the waste corn cob. Results: Method found to be linear in the range of 0.1 mg L-1 - 10 mg L-1, limits of detection and quantitation were found to be 0.0165 mgL-1 and 0.055 mgL-1, respectively. Tartrazine, in the real sample, was found to be 20.39 mgL-1 and 83.26 mgL-1. Conclusion: The developed UPLC-MS method is rapid, simple, precise and can be used for the quantitative analysis of tartrazine. The solid-phase extraction also involves a cost-effective procedure for extraction as it does not involve the commercial cartridge.
