Analysis of Pesticide in Tea: Chromatography-Mass Spectrometry Methodology

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.

Covers a wide range of research activities that are highly appropriate to current research methods Reflects the most recent research in nearly all cases, providing an excellent compilation of feasible methods needed for official analysis Describes methods that are internationally validated by an independent, U.S.-based organization (AOAC International)Authored by Dr. Pang, who is internationally recognized in the area of pesticide residues and other contaminants in foods
