Which of the following is NOT considered a biohazardous material?
A. Blood and body fluids
B. Micro-organisms
C. 1 M NaCl solution
D. Cell lines
C?
Bingo
To determine which of the given options is NOT considered a biohazardous material, let's understand the definition of biohazardous material first.
Biohazardous materials are substances that pose a potential risk to human health or the environment due to their biological nature. These materials may contain infectious agents, toxins, or other harmful biological substances.
Now, let's evaluate each option:
A. Blood and body fluids: Blood and body fluids can carry pathogens such as viruses, bacteria, or parasites, making them potential biohazards. Therefore, this option can be considered a biohazardous material.
B. Micro-organisms: Microorganisms, including bacteria, fungi, viruses, and parasites, can cause diseases and are often classified as biohazardous. Therefore, this option can be considered a biohazardous material.
C. 1 M NaCl solution: Sodium chloride (NaCl) is simply table salt and does not contain any living organisms or biological agents that pose a risk to human health or the environment. Hence, this option is NOT considered a biohazardous material.
D. Cell lines: Cell lines refer to a collection of cells cultured outside of an organism for research or diagnostic purposes. Depending on the specific cell line, it may or may not contain biohazardous materials. Since the option does not specify the type of cell lines, it is challenging to definitively determine whether or not this option is considered a biohazardous material.
Based on the given options, the correct answer is C. 1 M NaCl solution, as it is NOT considered a biohazardous material.
