One notable finding of the 2020 pink-salt study was that one of the 31 samples contained lead above the Australian/New Zealand national maximum contaminant level.

A Single-Sample Finding
The abstract reports lead above 2 mg/kg in one sample.
This does not mean all pink salts contain the same level of lead.
Variation in Natural Products
Natural mineral products can vary because of deposit geology, impurities, processing and supply-chain factors.
Product- or batch-specific laboratory analysis is therefore stronger evidence than generalising from a product category.
Regulatory Perspective
The authors argued that potentially harmful non-nutrient minerals should be considered in food regulation.
The finding illustrates the role of analytical quality control in natural mineral products.
