Is US air quality ever as bad as in Shanghai? (photos)
Yet another evening of bad Los Angeles air quality We won’t bore our readers by pointing out that last night [January 29, 2014] was yet another “Unhealthy for Sensitive Groups” bad air quality day in Los Angeles. (Sensitive Groups includes those athletically inclined.) You can read about the trials and tribulations of our air purifiers from previous days this week and this month. “Lower your standards!” We had a comment exchange on a social media site with someone in Shanghai regarding China’s consideration of spraying water from skyscrapers. China hopes this can bring PM2.5 down to 35 micrograms per cubic meter. We point out this is at the US 24-hour average but still way above the US annual average exposure limit (but below where it has sometimes been in Los Angeles recently). We previously discussed this new technology, and whether it should be applied in the U.S. “Lower (weaken) your standards!”… Read the restBad pollen day in your town? Tech recommendations.
Weather Channel pushes pollen advisories that might cause sneezing, but not PM2.5 EPA action days that might increase cancer risk? Today [January 25, 2014] the Weather Channel app pushed out a pollen advisory for Los Angeles. We’ve had their app installed for at least a year, and this is first time we’ve seen that push notification. (There was also a high surf advisory today for Los Angeles. Some of you may be wondering if we also got a polar vortex advisory out here; no we didn’t.) Mind you, pollen advisory went along with an EPA “Moderate” PM2.5 warning. That’s still above the World Health Organization’s PM2.5 dust average annual exposure limit guideline, but it’s not the “Unhealthy for Sensitive Groups” (Sensitive Groups including those athletically inclinded) and it wasn’t a PM2.5 concentration of 40 micrograms per cubic meter, waaaay above the 24 microgram WHO 24-hour average guideline, and even above the 35 microgram limit by the EPA and several other countries that we had two days ago out here.… Read the restWhy big city fitness gyms need to install clean air tech.
Third article in half a month on “Unhealthy for Sensitive Groups” bad LA air days Yet another bad air day in Los Angeles last night (see app screenshot) [originally published Jan 23, 2014]. We’ve now done three articles on ‘Unhealthy for Sensitive Groups’ bad air days in Los Angeles due to the Colby Fire and random automobile pollution just in the month of January alone. Incidentally, those “sensitive groups” involve working out at the fitness gym, which we’ll talk a bit more about in a bit. Despite a serious air purifier, our indoor PM2.5 dust particle counts on our Laser Particle Counter spiked around 10:30 PM Pacific Time yesterday, so we knew something was up. Running the numbers through our free app, they were starting to get bad. The EPA was still showing PM2.5 levels in the area as “moderate”, but EPA data is weighted average of 4-hour and 24-hour data (it sort of has to be), so it is delayed.… Read the restWildfire zone? Tech recommendations.
We saw our indoor PM2.5 counts skyrocket earlier this evening [originally published: Jan 18, 2014]. Los Angeles is essentially in a wildfire zone, so that smokey smell in the air gave us a suspicion of what this might be. We were waiting for the EPA numbers to catch up. 11:38 PM Pacific it finally has. EPA’s AQI had been hovering around 100 AQI (which is borderline between Moderate and ‘Unhealthy for Sensitive Groups’). With the 11:30 PM update, the air finally broke through in the Orange “Unhealthy for Sensitive Groups.” (Of course, keep in mind that the EPA numbers are time-averaged, a weighted average of a 4-hour and 24-hour average. So the air may have been bad for a while. And, we’re using the Central LA stations readings here; air quality will be different in different parts of LA.) As we mentioned in our earlier Colby fire post, the good news is you now, finally, have tools to take control of your indoor air quality.… Read the restRecent Comments
