The author concludes that prolonged exposure to sulfur fumes permanently damages a person’s sense of smell. This is based on a study comparing 100 workers from sulfur-emitting factoris and 100 workers who didn’t work in sulfur-emitting factories. On average, the sulfur-emitting factory workers identified fewer chemically-reproduced scents than the other group did.
The author assumes that the only explanation for why the sulfur-emitting factory workers identified fewer scents than the other group did is damage to sense of smell due to sulfur fumes. The author also assumes that the sulfur-emitting factory workers experienced “prolonged” exposure to sulfuar and that any potential damage to sense of smell they suffered is permanent.
