1988 OSHA PEL Project Nitrogen Dioxide | NIOSH | CDC

The current ACGIH TLVs for NO 2 are a 3ppm 8hour TWA and a 5ppm STEL, and they are based on human studies that indicate that normal respiratory function may be compromised at exposures below the current OSHA ceiling limit of 5 ppm NO 2. In particular, Kosmider, Ludyga, Misiewicz et al. (1972/ Ex. 1224) reported a slight reduction in vital capacity and maximum respiratory volume in 70 men ...

Nitrogen dioxide Wikipedia

30 ppm (guinea pig, 1 ... NO 2 is paramagnetic due to its unpaired electron, while N 2 O 4 is diamagnetic. The chemistry of nitrogen dioxide has been investigated extensively. At 150 °C, NO 2 decomposes with release of oxygen via an endothermic process ΔH = 14 kJ/mol): 2 NO 2 → 2 NO + O 2 As an oxidizer. As suggested by the weakness of the N–O bond, NO 2 is a good oxidizer. Consequently ...
