Metals Analysis

Cannabis has been shown to accumulate heavy metals and other elements from the soil and/or water in which they are grown. While less common, marijuana cultivated indoors can also be contaminated when exposed to fertilizers or pesticides that contain these heavy metals. Heavy metals, if present, are a concern due to exposure through the inhalation or consumption of contaminated cannabis. Excessive human exposure to heavy metals has detrimental consequences on the body and can cause serious health problems including neurological damage. Anandia Labs uses microwave digestion and inductively-coupled plasma mass spectrometry (ICP-MS, USEPA method 6020A R1 2007) detection to test for Arsenic, Cadmium, Lead, and Total Mercury levels in cannabis flower and extracts.

In addition, we can test for the following additional 27 metals to help inform plant uptake of micro-nutrients or other metals of concern:

  • Aluminum (Al)
  • Antimony (Sb)
  • Barium (Ba)
  • Beryllium (Be)
  • Bismuth (Bi)
  • Boron (B)
  • Calcium (Ca)
  • Chromium (Cr)
  • Cobalt (Co)
  • Copper (Cu)
  • Iron (Fe)
  • Magnesium (Mg)
  • Manganese (Mn)
  • Molybdenum (Mo)
  • Nickel (Ni)
  • Phosphorus (P)
  • Potassium (K)
  • Selenium (Se)
  • Silver (Ag)
  • Sodium (Na)
  • Strontium (Sr)
  • Thallium (Tl)
  • Tin (Sn)
  • Titanium (Ti)
  • Uranium (U)
  • Vanadium (V)
  • Zinc (Zn)
