Environment & Energy

My eyes started to cross after the first paragraph, and I’ll admit I couldn’t make it far, let alone all the way through the article. However, I will offer this:

The problem with lead in paint is that it’s easy for it to become airborne (sanding) or ingested (peeling or chipping). The problem with lead in water pipes is that it can dissolve in the water (read up on Flint, MI for info on why this often isn’t an immediate issue, but can quickly become a major problem). The problem with lead in gasoline is that it is burned, directly putting the lead into the air.

From what I understand about the use of perovskites in solar cells, none of this is an issue. It’s not likely that the lead will ever be released into the environment in an unsafe manner (perhaps via wildfires, but that would present a plethora of problems). The only time the lead would be exposed directly or dissolved would be during manufacturing or recycling of the panels, and that would be in a controlled manner.
