medium Q4 of 15
General Science - Physics (Basics)
Which of the following is a major effect of mercury pollution in water bodies?
AReduction in water temperature
BIncrease in dissolved oxygen
CBioaccumulation causing neurological damage
DIncrease in aquatic plant growth
Step-by-Step Solution
  1. Step 1: Understand mercury pollution effects

    Mercury is a toxic heavy metal that accumulates in aquatic organisms.
  2. Step 2: Analyze effects

    Mercury bioaccumulates in fish and causes neurological damage in humans and animals consuming contaminated fish. It does not increase dissolved oxygen or reduce water temperature. It also does not promote aquatic plant growth.
  3. Final Answer:

    Bioaccumulation causing neurological damage → Option C
  4. Quick Check:

    Mercury pollution effect = Bioaccumulation and neurological damage ✅
Quick Trick: Link mercury to bioaccumulation and nervous system harm.
Common Mistakes:
  • Mistaking mercury effects for oxygen or temperature changes.
