If a person is injected by a shot of a gun and all the bullets are not removed from his body it may cause poisoning by:
Correct answer: B. Pb
- A. Hg
- B. Pb
- C. Fe
- D. As
Explanation
Lead poisoning is an unusual and frequently overlooked medical complication of gunshot wounds with retained bullet fragments. Lead is commonly found in bullets and the explosive that ignites gunpowder. The management of lead intoxication is centred on the discontinuation of lead exposure and the chelation of lead from the body. Hence, only option B is correct.

About Reactions of Group IV Elements
Group IV, or Group 14, chemistry covers the trends from carbon and silicon to tin and lead, including their reactions with oxygen, halogens, water, acids and alkalis. It also examines the structures and properties of their oxides and chlorides, oxidation states, and the inert pair effect, rather than treating all members as equally metallic.
