The claim
Saharastof werd in het laboratorium getest en bestaat voor 50 procent uit aluminium en 38 procent uit zink.
Rating
Nee, want zuiver aluminium en zink komen in Saharastof niet voor. Hun geoxideerde vormen wel, maar in beperkte mate. Voor het meerendeel bevat Saharastof kwarts. Bovendien zijn de laboratioriumuitslagen op meerdere vlakken twijfelachtig.

The review says the reported percentages are unreliable: experts questioned the sample and testing method, and noted that Saharan dust’s elements occur mainly in oxidized forms. It also explains that the reported figures may reflect a unit-conversion error and that the dust is primarily quartz.[S1]
Additional context
The tested sample was described as Saharan sand collected from a glass table on 4 April 2024. [S1]
The review reports that the device used was intended to identify elements, not quantify their amounts. [S1]
