Which of the following materials could develop a bad odor from fumigation with methyl bromide?

• A. Vinyl
• B. Cinder block
• C. Wood composites
• D. Glass

Answer: (B)

Cinder block is a material that can develop a bad odor from fumigation with methyl bromide due to its porous nature and the potential for chemical reactions within the material. When methyl bromide is used for fumigation, it can penetrate various materials, and in the case of porous substances like cinder block, the fumigant may interact with any residual organic matter, moisture, or other chemicals within the pores. This interaction can create undesirable odors as the fumigant breaks down or reacts during and after the application process. In contrast, materials such as vinyl, wood composites, and glass have different properties that affect how they react to methyl bromide exposure. Vinyl and glass are generally non-porous, which limits the extent to which they absorb gases and develop odors. Wood composites, while they can absorb some volatile compounds, typically do not produce the same degree of odor as cinder blocks when exposed to methyl bromide because of their composition and treatment methods. Therefore, cinder block is the most likely candidate to develop a bad odor from this specific fumigation process.
