nonexposed

They found no differences between the exposed and nonexposed cohort for the Manifest Anxiety scale or the Self-rating Depression scale.

However, at UV doses much higher than typically used in upper room UV applications, this method was unable to distinguish between UV irradiated aerosols and nonexposed aerosols.

In a cohort study of workers occupationally exposed to acetone at levels exceeding 500 ppm, Satoh et al. (1996) found an increase in reports of eye irritation and nausea compared with a nonexposed control cohort.

More specifically, a study was conducted where a group of prenatally exposed and a group of nonexposed young adults, between the ages of 18-22, performed a visuospatial working memory task, while receiving an fMRI that recorded the functional neural activity in the young adults.

Previous studies have shown that UV inhibits PCR assays in single and double stranded RNA viruses, [ 28 29 ] while our RT-PCR method did not detect a difference between UV exposed and nonexposed rhinoviral aerosols.
