Analysis of Pesticide in Tea: Chromatography-Mass Spectrometry Methodology is a comprehensive book, providing serial, rapid, high-throughput analytical methods for determining more than 600 pesticides in tea. There are increasing numbers of strict limit standards for pesticide residues in edible agricultural products in countries all over the world. The threshold for pesticide residues in tea is high for international trade. At present, 17 countries and international organizations have stipulated MRL levels for over 800 pesticide residues in tea. All methods described in this book are validated by an independent, U.S.-based organization (AOAC International), and all indexes have satisfied AOAC International's criteria.

China has a history of 5000 years in growing tea and is a large tea producer with 80 million people involved in tea growing. China exports tea to over 100 countries worldwide, enjoying a high reputation for quality and variety.

Pang, Guo-Fang
Professor Pang owns more than 30 years' experience on the inspection and quarantine work, devoting himself to the research on the theory and practice of food scientific analysis and conducting the pioneering research work in the field of trace element analytical techniques of pesticide and veterinary drug residues. He has made many innovations in the study of new techniques of rapid detection of multiresidues with high sensitivity, high selectivity and high resolutions as well as in the study of new techniques and new methods. He makes many achievements in the standardization of analytical techniques and engineering, giving a boost to the development of the relative techniques of our country. He focuses his study on the high through-put techniques of the trace elements of over 1000 pesticides and veterinary drug residues and established 139 China National Standards and 3 AOAC Official Methods, improving the quality of relative products and giving an impetus to the development of foreign trade. He won the Second Prize of the State Scientific and Technical Progress 3 times. He published more than 110 papers and 10 books.
