Which metal is known to cause thick white smoke during cremation, affecting pollution controls?

• A. Lead
• B. Aluminum
• C. Zinc
• D. Copper

Answer: (C)

Zinc is known to produce thick white smoke when it is subjected to high temperatures during the cremation process. When zinc is burned, it forms zinc oxide, which can create a vapor that appears as a white smoke. This phenomenon can complicate pollution control measures, as the emitted zinc oxide can be a significant environmental concern. The presence of zinc in cremation containers, such as some types of caskets and medical implants, is particularly relevant in this context. In contrast, while other metals like lead and aluminum can also present hazards during cremation, they do not typically produce the same thick white smoke associated with zinc. For example, lead can create harmful fumes but falls into a different category of concern in terms of smoke generation. Understanding the specific properties of these metals during cremation enables better management of environmental impacts and adherence to pollution control standards in mortuary practices.
