Arsenic and mercury?
Again and again, however, there are reports that algae from China are sometimes significantly contaminated with pollutants. They are often grown there in polluted waters, and due to their binding properties, they can accumulate heavy metals. However, EU production of organic quality can rule out contamination with arsenic, mercury, or other undesirable substances. That is why we purchase our non-toxic organic products specifically from countries of the European Union.
