What hazard is associated with older preserved specimens?

• A. They pose no risk.
• B. They were preserved with arsenic and could be dangerous.
• C. They attract pests only.
• D. They last forever.

Answer: (B)

Older preserved specimens can be hazardous because they were commonly treated with arsenic-based preservatives to prevent decay and deter pests. Arsenic compounds are toxic, so handling old mounts, skins, or taxidermy dust can pose health risks through inhalation or skin contact. This makes the main hazard the chemical toxicity of the arsenic, not just a nuisance from pests or an eternal lifespan of the specimen.

That’s why this option is the best: it identifies the actual danger—arsenic used in preservation—and explains why it matters for anyone who might handle older specimens. Other choices miss the key issue or mischaracterize the risk: they aren’t risk-free, the primary hazard isn’t merely attracting pests, and preservation materials don’t imply that specimens last forever.
