A feasibility study of the ozone formed from the oxidation of nitrogen dioxide in ambient air reported by the WHO suggested that daily deaths of 1 to 2% is attributed to exposure to ozone concentration above 47.3 ppb and exposure above 75.7 ppb is attributed to 3 to 5% increase in daily mortality. A level of 114 ppb was attributed to 5 to 9% ...
Ozone depletion is a separate problem caused by chlorofluorocarbons (CFCs) [231] which have been released into the atmosphere. [232] However, CFCs are strong greenhouse gases . [ 233 ] [ 234 ] Further, the hole in the ozone layer is shrinking and in 2019 was the smallest it had been since 1982, [ 235 ] [ 236 ] while global warming continues.
Sweat and body odor are typically thought to go hand in hand, but experts say it's a little more complicated than that. Sweat alone doesn't have a smell, according to Harvard Health.
Body odor can provide MHC information. Although less is known about how odor is influenced by MHC genes, possible explanations have been that microbial flora [70] or volatile acids [71] are affected by the gene, which can be detected in body odor. Female mice and humans have both shown odor preferences for males with MHC-dissimilarity. [72]
