Study Notes
Types of Water Pollution
- Non-Point Source Pollution: runoff from agricultural fields carrying fertilizers and pesticides into nearby streams, causing eutrophication, algal blooms, and oxygen depletion.
Types of Water Pollution (continued)
- Nutrient Pollution: excessive use of fertilizers in farming leading to nutrient runoff into rivers, causing algal blooms, fish kills, and degradation of aquatic ecosystems.
- Oil Pollution: oil spills from tanker accidents or offshore drilling operations, harming marine life, damaging coastal ecosystems, and causing economic losses for fishing and tourism industries.
- Plastic Pollution: improper waste disposal, littering, and inadequate recycling systems leading to marine pollution, ingestion by marine animals, entanglement, and disruption of food chains.
- Thermal Pollution: discharge of heated water from power plants into rivers or lakes, causing changes in aquatic ecosystems, reduced oxygen levels, and harm to fish and other aquatic organisms.
- Sediment Pollution: soil erosion from construction sites or deforested areas entering water bodies, causing increased turbidity, sedimentation, and habitat destruction for aquatic organisms.
- Chemical Pollution: discharge of toxic chemicals from industrial facilities into waterways, contaminating water sources, poisoning aquatic life, and posing health risks for humans.
- Radioactive Pollution: discharge of radioactive waste from nuclear power plants into water bodies, increasing cancer risks, genetic mutations in aquatic organisms, and long-term environmental damage.
- Microplastic Pollution: breakdown of larger plastic items and microbeads in personal care products, causing ingestion by marine organisms, bioaccumulation in the food chain, and potential harm to human health.
