I was shown these strips and asked what is LV pacing threshold (test done at VVI 90ppm). What do you think? #PacemakerSkills
Did you know that KitchenAid KitchenAid Canada has tools with 2434ppm lead in them. For reference 90ppm is food safe. They won't swap the. Out for the stainless version but are offering a sale price of $139. They're currently under a class action lawsuit. Check your mixer!
Die CO2 Konzentration in unserer Atmosphäre ist von März 2020 auf März 2021 um 2,90ppm gestiegen. Jetzt im April haben wir ein seit Menschengedenken noch nie dagewesenes Niveau von 420ppm gemessen. Mit steigender C02-Konzentration steigt auch die Temperatur. #Klimawandel
Need to harmonize lead content standards to a maximum limit of 90ppm. #LeadFreeKids #StopLeadPaint event at #UNEA2
When I joined Twitter 10 years ago, global CO2 was <390ppm, now it's >410. I'm not sure any other index of sustainability has moved in the right direction over that time either. I'd love us to have reversed that by my 20th. Can you do that for me Twitter? #MyTwitterAnniversary
Lack of servicing gives you this and co of 890ppm. A bit of looking after and the co is down to 90ppm and the boiler is happy. #happyboiler
