TL;DR: Investigation of the toxic effect of 100 nm negatively or positively charged zinc oxide NPs administered by gavage in Sprague Dawley rats established a no observed adverse effect level, and identified target organ(s) to be the stomach, pancreas, eye, and prostate gland, to speculate that this inflammatory damage might result from continuous irritation caused by both test articles.

TL;DR: iBA showed no abnormal observations in all the experimental parameters at any concentration under this experimental condition, and it is suggested that 150 ppm is safe enough for the PEL of iBA in the working areas, even taking into onsideration that OSHA lowered the Pel to 50 ppm for fear of the probable risk of its skin irritation.
