Difficulty: EasySoil Pollution, Pesticides, Heavy Metals, and Waste Management

Match each environmental contaminant or waste management process in Column A with its corresponding chemical characteristic or primary effect in Column B.

  • Lead (Pb\text{Pb})Toxic heavy metal from battery manufacturing and old paints causing neurological harm
  • DDT (Organochlorine)Persistent synthetic pesticide that bioaccumulates up the agricultural food chain
  • IncinerationHigh-temperature thermal waste disposal process that converts combustible refuse into ash

Answer

Lead (Pb\text{Pb}) matches with 'Toxic heavy metal from battery manufacturing and old paints causing neurological harm'. DDT (Organochlorine) matches with 'Persistent synthetic pesticide that bioaccumulates up the agricultural food chain'. Incineration matches with 'High-temperature thermal waste disposal process that converts combustible refuse into ash'.
Each item correctly matches its specific chemical, environmental, or waste management role: Lead is a heavy metal associated with battery waste and nervous system toxicity; DDT is a non-biodegradable pesticide causing bioaccumulation; Incineration is thermal combustion reducing waste to ash.

Step-by-Step Solution

1
Identify the primary environmental impact of Lead (Pb\text{Pb}).
Lead is a non-biodegradable heavy metal commonly sourced from lead-acid batteries and paints, causing neurological dysfunction.
Heavy metal contamination in soil primarily stems from industrial effluents and battery production.
2
Identify the characteristic behavior of DDT in soil and ecosystems.
DDT is an organochlorine pesticide notorious for environmental persistence and fat-solubility, causing bioaccumulation in higher trophic levels.
Organochlorine pesticides resist rapid chemical and biological decomposition.
3
Identify the operational principle of waste Incineration.
Incineration thermal treatment burns solid waste at high temperatures, turning organic matter into gaseous products and non-combustible ash.
It is a thermal waste volume reduction method commonly employed in municipal waste management.
