Worth noting from the study is that they only tested 3 brands' models of disposable vapes (Esco Bar, Flum Pebble, and ELF Bar)... all of which are not authorized for sale by the FDA. Although as also noted in article and the study, "the FDA has issued several warning letters and taken enforcement action against the manufacturers of ELF Bar and Esco Bar in its commitment to protect youth against illegal flavored, disposable e-cigarettes, yet these products still exist in the market and are among the most popular with youth."
p.s. Another interesting finding from the study on the likely sources of the contamination:
The source(s) of metals and metalloids measured in virgin e-liquids were assessed using the elemental composition of device components (Figure 1, Tables S1 and S2). In Esco Bar devices, the relatively high concentrations of Pb, Ni, Cu, and Zn in virgin e-liquids align with the composition of the leaded bronze alloy sheaths and battery connectors (Figure 1D). This evidence suggests that these two metallic components are the sources of these metals leaching into Esco Bar e-liquids prior to device operation. Sb was not identified in any internal metallic component analyzed but was present at comparatively high concentrations in select e-liquids (Flum Pebble, Esco Bar, and ELF Bar Flavored 0% Nicotine) (Table S2). Thus, in virgin e-liquids, metals and metalloids from heating components were at relatively low concentrations across all devices aside from Ni, whereas contamination of virgin e-liquids was observed due to leaching of elements from nonheating components (sheath and battery connectors releasing Pb, Cu, and Zn) or from unknown sources (Sb).

Clickbait headline, and an article that must be read critically to make sense of what's going on:
Some popular disposable e-cigarettes emit toxic metals at levels that surpass those found in traditional cigarettes and earlier generations of vapes
This is true! But toxic metals aren't the main cause of health problems from traditional cigarettes, tar is, and e-cigarettes still don't have any tar. And reading over the study, it seems like most the heavy metal contents are 2x or 3x over the risk limits in the study, not 10x or 100x over the limit. Still a major issue to be solved, but if I was using these devices this is not something I'd loose any sleep over.
Especially concerning to me is the comparison to earlier vapes. These earlier, apparently safer, vapes didn't fall out of favor due to consumer demand. They were effectively banned by regulators, and the new "bar" models attempt to side-step those regulations:
