Trace Detection of Heavy Metals in Tobacco Simple, Rapid, Sensitive and Accurate Method Based on ICP-MS

摘要

Plants, and in particular tobacco plants, hemp tea leaves, and flowers (a non-psychoactive variant of cannabis) are well-known to absorb trace elements from the soil and to accumulate them in their leaves. Some of these elements are toxic to humans even in minute quantities. As they grow, plants can bioaccumulate metals in their tissues that originate from the soil and water in their surroundings. These metals can naturally occur in soils and water as part of their mineral content. They may also be artificially introduced in the form of fertilizers or crop protection products to increase the yields.
