UCLA team finds high levels of dangerous air particles(PM2.5) in air near electric vehicle fast charging stations.

  Now do PM and VOC levels at petrol stations.

  Then PM and VoC levels on roads entirely occupied by combustion vehicles, and entirely occupied by electric vehicles.

    It’s like this is perfectly crafted to demonstrate a spurious correlation.

    I get what you’re saying but I’m not seeing this as “electric cars suck” but more as “we found another place where we can improve”

    This seems to me an issue that can be fixed with a few air filters which would require very infrequent replacements

      2.5 takes some fairly serious filters.

    I too love a heavy dose of whataboutism with my science.

    I think we all know petrol is worse by a huge margin. More knowledge about electric vehicles and their effects is just more good for engineers.

      It’s a thing called data bestie

  • The tiny particles likely come from particle resuspension around Direct Current Fast Charging power cabinets. Cooling fans designed to prevent the electronics from overheating can also stir up dust and particles from internal surfaces.

  a) that doesn’t really sound like the fault of EVs or the charging stations themselves. Any sort of very moderate air current would cause the same problem.

  b) that sounds pretty easy to fix with some filters simple pleated filters, and that would leave the surrounding environment cleaner than they used to be.

    Excactly. The stations themselves don’t create particles but magnetic fields from the high voltage DC lines and cooling fans just pick them up from the ground and back to air. It’s quite misleading to claim this is “Fine particulate matter emissions from electric vehicle fast charging stations” as the stations just redistribute existing emissions.

    Obviously this is not a good thing, but the underlying cause is something else than these stations, I’d bet considerable amount of it comes from combustion engines. And as you said, simple filters should fix the problem and clean up the pollution from environment as well.

    From the people who think windmills cause cancer?

    Also they’re likely in more densely populated areas which already have lower air quality.

      This seems accounted for since the comparative samples are from “similarly urban areas”

  Jesus they will release any study to try and smear electric. It’s the same argument as cigs vs vapes. Yes they’re both bad and not the best solution, but one is obviously better than the other. Plus how are they separating contamination of the charging stations from any other area where normal ass cars operate. There’s just as much of a chance if not more that those particles are from the gas vehicles driving around, and not something specific to the chargers.

    They’re not separating data throughly. Researcher Yifang Zhu, over many publishings, mainly gathers and publishes raw findings. Such as… (summarizing) “Children are at risk due to immature respiratory systems and faster breathing rates… by traveling in diesel powered school buses in my South Texas study.”

    Dafuq.

    This is the craziest reaction to knowledge

    Knowing something new we didn’t before means… We know more now.

    Stop trying to politicize this.

      i don’t know if i would take this study as “knowledge”. that map of the us? it’s fake. reading the study, they were only measuring in one county. the error bars overlap enough that this could all be errors.

      question is, why publish it if it is so obviously (and willfully) wrong?

  Look at the map this is just higher near larger population, Correlation vs. Causation. This smells like bull shit.

    A research participant, Yifang Zhu, is tied to a thing called Mobility Justice Frameworks. It’s pushing for greenspaces in urban areas, including making existing infrastructures appear in a bad light for its cause(s).

    Do you not see the summary text in your front end, or did you just not read it? This is what it looks like on the default web front end on my instance:

      I also saw where they used a graphic of the entire US when the study only encompasses 1 county in California.

      Were those other urban areas specifically parking lots/garages? (The places that charging stations tend to be)

    My best guess. Create media for campaigns for lawmakers to push for more greenspaces in urban areas.

  Sounds easily enough to fix with a couple of filters…
