Final answer:
The ceiling threshold limit value for glutaraldehyde is 0.2 parts per million (ppm).
Step-by-step explanation:
The ceiling threshold limit value for glutaraldehyde is B) 0.2 parts per million (ppm). Glutaraldehyde is used in health science applications, including the sterilization of medical equipment. It is important to be aware of its concentration limit because, much like formaldehyde, it can irritate the skin and the mucous membranes.
Parts per million (ppm) is a measure of the concentration of a substance in a mixture or solution. While ppm is a common unit, it's essential to convert between concentration measurements accurately. For instance, comparing parts per million (ppm) and parts per billion (ppb) is essential in environmental science, where standards like the EPA's action limit for substances like lead in drinking water are strictly regulated.
