Ans. is ‘a’ i.e., Collect carefully and recycle
o All mercury and mercury-containing items should be recycled.
o It should never be poured down a drain or sewer, flushed down a toilet, or thrown in the thrash.
o As long as mercury is recycled, it will stay in the recycling loop, going into new products rather than into the environment.

A factory worker presented with tremors and personality change. On Examination his hands show the Following picture. Most probable diagnosis is
| A |
Mercury Poisoining |
|
| B |
Lead Poisoining |
|
| C |
Arsenic Poisoining |
|
| D |
Narcotic Poisoining |
Symptoms described of Mercury Poisoining. The Image shows Acrodynia is also known as Feer’s disease or pink disease. It is caused by mercury toxicity.
The mechanism by which mercury causes damage ‑
| A |
Binds to -SH group of enzyme |
|
| B |
Directly toxic |
|
| C |
Inhibits ETC |
|
| D |
Inhibits protein synthesis |
Ans. is ‘a’ i.e., Binds to -SH group of enzyme
- Heavy metal toxicity is caused by tight binding of a metal such as mercury (Hg), lead (Pb), aluminium (Al), or iron (Fe) to a functional group of enzyme.
- Mercury, for example, binds to reactive sulfhydryl groups (-SH) in the active site of so many enzymes, that it has been difficult to determine which of the inhibited enzyme is responsible for mercury toxicity.
- Lead also has high affinity for sulfhydryl group.
