Toxic elements and heavy metals: Mercury, Arsenic, Cadmium and Lead:

We also tested all the brands for toxic elements and nutritive minerals. For the toxic elements, we look at Mercury (Hg), Arsenic (As), Cadmium (Cd) and Lead (Pb).

On the positive side, all the brands tested at zero mercury. This is expected, since mercury is “sticky” and very rarely finds its way into agricultural products unless plants are grown in a toxic mercury dump.

Here are the toxic element results we found:

379.4(As) 152.7(Cd) 285.9(Pb)
