pollution

• What are the differences between point source and non-point source pollution?

  • Point Source Pollution:
  • Single, identifiable source
  • Easier to monitor and control
  • Examples: factory discharge, sewage treatment plant

  
  

  • Non-Point Source Pollution:
  • Multiple, dispersed sources
  • More complex to manage
  • Examples: agricultural runoff, urban stormwater
• What are the impacts of nitrogen pollution on ecosystems?

  • Contributes to acid rain
  • Causes eutrophication (algal blooms)
  • Affects soil, water, and air quality
• What are the pathways through which water pollution occurs?

  1. Industrial/agricultural discharges
  2. Natural processes (toxic minerals, seepage)
  3. Atmospheric deposition (SO₂ and NOx)
  4. Nutrient enrichment (excess fertilizers)
• What is the significance of understanding pollution types?

  It helps in developing effective management strategies.
• What is dry deposition in the nitrogen pollution cycle?


  It directly affects nearby vegetation.
• What is the role of wet deposition in nitrogen pollution?

  It involves nitrogen compounds dissolving in rain.
• What are the consequences of nitrogen pollution on ecosystems?

  It contributes to acid rain and eutrophication.
• How does nitrogen leaching affect water systems?

  It leads to oxygen depletion and toxic contamination.
• What is the impact of agricultural emissions on the nitrogen cycle?

  They contribute to nitrogen deposition in ecosystems.
