Hopkins Study?

So I read this new study from Hopkins that says we're getting some metal in vapor. Not news to me I just always thought it wasn't more metal than is in cigarettes and the metal is a small part of what makes a cig bad. Still, I was reading the press release and it doesn't really make sense to me. The text said there are 15 micrograms of lead in vapor per KILOGRAM (median). I'm assuming that a kilogram of vapor is about a Kilo of juice. So if e juice and water are comparable in weight (are they?) that would be per liter of vaped e juice. By comparison there are two micrograms of lead in a cigarette. Am I interpreting this correctly or am I living in a dreamworld?

Farsalinos blasts Johns Hopkins ‘study’ claiming e-cig vapor is high in arsenic, metals


https://www.vapes.com/blogs/news/fa...aiming-e-cig-vapor-is-high-in-arsenic-metals#

"However, Farsalinos has been conducting scientific studies involving the perceived toxicities of e-cig vapor since 2011, and he aggressively refutes the findings. While he does agree that small amounts of lead and chromium can sometimes be found in e-cig vapor vaped at excessively high temperatures, he also claims that the “significant” levels as described by Johns Hopkins are intentionally misleading.

“For those asking questions about the latest study on metal emissions from e-cigarettes, here is my comment: The ‘significant amount’ of metals the authors reported they found were measured in ug/kg. In fact, they are so low that for some cases (chromium and lead) I calculated that you need to vape more than 100 ml per day in order to exceed the FDA limits for daily intake from inhalational medications.”

“The authors once again confuse themselves and everyone else by using environmental safety limits related to exposure with every single breath and apply them to vaping. However, humans take more than 17,000 (thousand) breaths per day but only 400-600 puffs per day from an e-cigarette.”
