The Claim

Mercury is not uniformly detected in thyroid tissue across all individuals; its presence is patchy, with variability in the number of affected follicular cells and distribution across follicles, suggesting selective uptake or retention mechanisms.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Description
1 study reviewed
In plain English

Not everyone has mercury in their thyroid gland, and when it is there, it doesn't show up everywhere—it's scattered in small patches, which might mean the thyroid picks up mercury in a selective way.

Mercury is not detected in thyroid tissue of all individuals, and its presence is patchy within the gland, with variability in the number of affected follicular cells and distribution across follicles, suggesting selective uptake or retention.

  1. Study: Mercury in the human thyroid gland: Potential implications for thyroid cancer, autoimmune thyroiditis, and hypothyroidism

    Scientists found that mercury isn't in everyone's thyroid, and when it is, it's only in some cells — not all — and it becomes more common as people get older. This matches the idea that the body picks up mercury in a patchy, uneven way.
