50% reduction in known neurological toxic chemical is, IMHO, unacceptable.
- giantg2 5y agoSeems like 70% would be fine (article I saw was a small unvented kitchen with about 225 ppb). "The EPA has concluded that the current NAAQS protect the public health, including the at-risk populations of older adults, children and people with asthma, with an adequate margin of safety. The NAAQS for nitrogen oxides are a 1-hour standard at a level of 100 ppb based on the 3-year average of 98th percentile of the yearly distribution of 1-hour daily maximum concentrations, and an annual standard at a level of 53 ppb."
