Wouldn't it be more from suspended particles in the atmosphere?
That Sky article was unsurprisingly thin on anything other than fitting the term 'death zone' into it, so I wonder if other +8000m peaks in other areas like the Karakorum have been tested. Is this an indicator of pollution across the planet, or the pollution of Everest, or simply the South Col route etc.
Edit; apologies that sounds like I've made you Devil's Advocate, just musing out loud.
