Based on the video and the meter he's using, he seems to be measuring PM 2.5, PM 10, HCHO and TVOC, although he ends up focusing on HCHO (formaldehyde) and TVOC. All being measured as mg/m^3. It seems to be difficult to even find recommended levels of HCHO and TVOC. According to OSHA, they have a permissible formaldehyde level of 0.75 ppm averaged around 8 hours in the workplace. Of course, that's in ppm, not mg/m^3 though https://www.osha.gov/OshDoc/data_General_Facts/formaldehyde-factsheet.pdf For TVOC, this website below states that anything above 1 mg/m^3 in the air we breathe is high with anything below 0.5 mg/m^3 being acceptable. Not sure how they came to these conclusions though https://www.epa.gov/indoor-air-quality-iaq/volatile-organic-compounds-impact-indoor-air-quality and not much peer-reviewed research on this either. Good find. I noticed there is no mention of formaldehyde here unless its present by default in some of the conditioners mentioned in the link. But formaldehyde to my knowledge is mostly present in woods and tends to have a strong odor (which is something I've never smelled off vinyl records). That kind of raises my skepticism about the study and monitoring device used in the video and why even formaldehyde levels were supposedly increasing.
Hi everyone I was watching this video (https://www.youtube.com/watch?v=aZ2czFuIYmQ starting at 7:25) where they took an air quality meter (it looks like it was this one https://amzn.to/3kBUmCe), placed it beside a record on a turntable and the hazard levels started increasing for both TVOC and formaldehyde. Therefore, do vinyl records truly pose a threat to human health temporarily or over time? Also, was the experiment performed here solid or are there holes in this? Has anyone tried to replicate this experiment with a similar outcome? I've encountered many different comments in regards to vinyl toxicity for records and just PVC based items in general (pipes, toys, furniture, etc.). Some say no threat, others always a threat, others say it depends on the offgassing levels, only an issue when its burned, plasticizers used, hard to tell, etc. Same with formaldehyde.
