Environmental Pollution and Control
- Environmental pollution literally means surroundings
- Environmental pollution is a significant global issue
- Pollution is the addition of undesirable materials to air, water, and soil, exceeding natural concentrations.
- Pollutants harm human health and environmental quality.
- Pollution differs from contamination.
- Pollution involves an increase in existing substances to harmful levels, whereas contamination introduces foreign substances.
Types of Pollutants
- Primary pollutants: enter the environment directly (e.g., CO2, CO, H2S, NOx, NH3)
- Biodegradable pollutants: easily decomposed by microorganisms
- Non-biodegradable pollutants: not easily decomposed (e.g., domestic sewage, chemical wastes)
Types of Pollution
- Air pollution
- Water pollution
- Soil pollution
Sources of Air Pollution
- Natural processes (e.g., volcanic eruptions, dust storms)
- Human activities (e.g., burning fossil fuels, industrial emissions, deforestation)
Major Air Pollutants and Effects
- Carbon monoxide (CO): reduces oxygen-carrying capacity of blood
- Sulfur dioxide (SO2): damages respiratory systems, buildings
- Other pollutants can cause respiratory problems, cardiovascular issues, and other health problems.
Aquatic & Terrestrial Ecosystems
- Aquatic ecosystems include oceans, lakes, streams, estuaries, wetlands.
- Terrestrial ecosystems are land-based, such as tundra, grasslands, forests, and deserts.
- Both have biotic (living) and abiotic (non-living) components.
- Food chains and food webs illustrate energy flow in ecosystems.
Food Chain & Food Webs
- Food chains show a linear sequence of energy transfer through different trophic levels (producers, primary consumers, secondary consumers)
- Food webs present a more realistic depiction of interconnected food chains within an ecosystem.
- Producers (plants) form the base.
- Consumers feed on producers or other consumers.
Energy Efficiency in Food Chains
- Energy transfer is inefficient.
Carbon Cycle (diagram)
- Shows carbon movement between atmosphere, biosphere, hydrosphere, and lithosphere through processes like photosynthesis, respiration, and combustion.
Phosphorus Cycle (diagram)
- Depicts phosphorus movement through the environment, including absorption by plants, consumption by animals, and decomposition.
Global Warming
- Increasing global temperatures due to increasing greenhouse gases in the atmosphere.
Water Pollution Issues
- Release of substances into water bodies, making them unsafe for use and harming aquatic life.
- Types of water pollutants include toxic wastes, petroleum products, and disease-causing microorganisms.
- Sources can be from industrial discharges, sewage, agricultural runoff, or accidental spills
Control of Water Pollution
- Strategies to minimize pollution, such as proper waste disposal, reduced pesticide usage, and industrial effluent treatment.
Physical & Chemical Standards of Domestic Water
- Specific standards for drinking water quality, including pH, turbidity, total dissolved solids, hardness, and alkalinity.
Sources of Air Pollution
- Mobile sources (vehicles)
- Stationary sources (power plants, factories)
- Natural sources (dust storms, wildfires)
