Phytoremedition of Metal Contaminated Soils

Collaborators: Mark Zierden, LSSU; Hannah Clause, LSSU; Ben Southwell, LSSU

Our work investigates metal accumulation in Cannabis and other plants for the development of Phytoremediation Applications. Cannabis is well known to be an efficient accumulator of metals, but little is known about the mechanisms of metal tolerance and homeostasis. We seek to elucidate these mechanisms using a combination of microanalysis/chemical imaging techniques and mass spectrometry. We are also collaborating with the Zierden group in search of additional novel hyperaccumulator species. For more information visit: https://zierdenlab.com/

Contaminants in Cannabis

Collaborators: Mark Zierden, LSSU; Hannah Clause, LSSU; Ben Southwell, LSSU

Our work in the Cannabis is related to metal uptake, foreign matter, and consumer product safety. We utilize ICP-MS, Light Microscopy, LDIR, and SEM-EDS to quantify metal contaminants and identify sources and types of particulate contaminants.

Heavy Metals in Cannabis Rolling Papers

Collaborators: Ben Southwell, LSSU; Michelle Jarvie, LSSU; David Edwards, JEOL; Chip Cody, JOEL; Judy Westrick, WSU; Sameera Perera, WSU.

The composition of (non tobacco) rolling papers is largely unregulated in the United States, leading to a potential for unsafe products entering the market. We are currently investigating the elemental composition (heavy metal content) of cannabis rolling papers, and have documented circumstances in which product design and manufacturing might potentially present a human health risk, such as the use of certain plastic components and metal based pigments.
