Description

The surge of interest in cannabis-based medicinal products has put an extremely high demand on testing capabilities, particularly for contaminants such as heavy metals, which are naturally taken up through the roots of the plants from the soil, growing medium, and fertilizers but can also be negatively impacted by the grinding equipment and extraction/distillation process. Unfortunately, many state regulators do not have the necessary experience and background to fully understand all the safety and toxicological issues regarding the cultivation and production of cannabis and hemp products on the market today.

Measuring Heavy Metal Contaminants in Cannabis and Hemp offers a comprehensive guide to the entire cannabis industry for measuring elemental contaminants in cannabis and hemp. For testing labs, it describes fundamental principles and practical capabilities of ICP-MS and other AS techniques for measuring heavy metals in cannabis. For state regulators, it compares maximum contaminant limits of heavy metals with those for federally regulated pharmaceutical materials. For cultivators and processors, it helps them to better understand the many sources of heavy metals in cannabis. And for consumers of medical cannabis, it highlights the importance of choosing cannabis products that are safe to use.

Other key topics include:

The role of other analytical techniques for the comprehensive testing of cannabis products

Tips to optimize analytical procedures to ensure the highest quality data

Guidance on how to characterize elemental contaminants in vaping liquids and aerosols

Suggestions on how to reduce errors using plasma spectrochemistry

The role of certified reference materials to validate standard methods

Easy-to-read sections on instrumental hardware components, calibration and measurement protocols, typical interferences, routine maintenance, and troubleshooting procedures

Written with the cannabis testing community in mind, this book is also an invaluable resource for growers, cultivators, processors, testers, regulators, and even consumers who are interested in learning more about the potential dangers of heavy metal contaminants in cannabis and hemp.

About the Author

Robert (Rob) Thomas is the principal of Scientific Solutions, a consulting company that serves the training, application, marketing and writing needs of the trace ele¬ment user community. He has worked in the field of atomic and mass spectroscopy for more than 45 years, including 24 years for a manufacturer of atomic spectroscopic instrumentation. He has served on the American Chemical Society (ACS) Committee on Analytical Reagents (CAR) for the past 20 years as leader of the plasma spectrochemistry, heavy metals task force, where he has worked very closely with the United States Pharmacopeia (USP) to align ACS heavy metal testing procedures with pharmaceutical guidelines. Rob has written almost 100 technical publications, including a 15-part tutorial series on ICP-MS. He is also the editor and frequent contributor of the Atomic Perspectives column in Spectroscopy magazine. In addition, Rob has authored three textbooks on ICP-MS and in 2018 completed his fourth publication, entitled Measuring Elemental Impurities in Pharmaceuticals: A Practical Guide. He has spent the past two years researching and writing this new book, Measuring Heavy Metal Contaminants in Cannabis and Hemp. Rob has an advanced degree in analytical chemistry from the University of Wales, UK, and is also a Fellow of the Royal Society of Chemistry (FRSC) and a Chartered Chemist (CChem).
