Pesticide residues in tea leaves always raise public concerns as drinking tea is an integral part of everyday routine for many people. Also, pesticide residues may cause acute or chronic adverse health effects. There are hundreds of pesticides in the tea and the residue level of pesticide in the tea brew is closely related with the water solubility of pesticide. The higher water solubility of pesticide showed higher extractive rate of pesticide during the brewing process from dry tea.
Bonna-Agela Technologies will exhibit on Pittcon 2014 between 2 and 6 March 2014 in McCormick Place, Chicago, IL USA. The Pittcon is the world's largest annual premier conference and exposition on laboratory science. It is organized by The Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy, a educational corporation which is comprised of the Spectroscopy Society of Pittsburgh (SSP) and the Society for Analytical Chemists of Pittsburgh (SACP). Having grown beyond its roots in analytical chemistry and spectroscopy, Pittcon has evolved into a conference & expo that now also serves a diverse constituency encompassing life sciences, pharmaceutical discovery and QA, food safety, environmental and bioterrorism markets. Bonna-Agela Technologies will show you the up-to-date products and technologies during the exhibition time (Booth 3309) and will also have specialists to present advance research and technical data and new solutions in following topics:
Biobest and on behalf of Bonna-Agela Technologies will attend the 40th International Symposium on High Performance Liquid Phase Separations and Related Techniques in Hobart, Tasmania, Australia which will be held during 18th - 21st November 2013. The HPLC conference series is the world's premier meeting dedicated to liquid phase separation science. This international meeting series is multi-disciplinary in nature and brings together many of the world's leading authorities to address the major practical and theoretical challenges related to all aspects of liquid phase separation science techniques. This will be the first time that the HPLC conference is held in the Australasian region and this will create a unique opportunity for Australasian scientists to meet with colleagues from throughout the world and to share their latest results.

There are hundreds of pesticides in the tea and the residue level of pesticide in the tea brew is closely related with the water solubility of pesticide. The higher water solubility of pesticide showed higher extractive rate of pesticide during the brewing process from dry tea. With development of new technology, an efficient and sensitive method has been established for simultaneous determination of 653 pesticides in teas by GC/MS and HPLC/MS/MS. The method involved extraction with acetonitrile followed by clean up using Agela's Cleanert-TPT SPE and subsequent identification and quantitation of 490 pesticides by GC/MS and 448 pesticides by HPLC/MS/MS. more information
China's biggest dairy companies the Mengniu Dairy Co. said over the Christmas holiday that its products at a plant in Sichuan province were found by the government quality watchdog to contain over the limits of aflatoxin M1 (AFM1), a substance that can cause severe liver damage, including liver cancer. The company lost almost one-fourth of its value on Wednesday after its shares plunged 26 percent to their lowest level in more than two years. The discovery of the toxins is the latest of several safety scares to hit China's dairy industry in recent years.
In 2008, at least six children died and nearly 300,000 became ill from powdered milk laced with melamine, an industrial chemical added to low-quality or diluted milk to give misleadingly high readings of protein levels.
