    • Match the aquatic and terrestrial pollutant with its source:
      Nitrogen (NN) ↔️ Agricultural runoff, sewage, industrial waste
      Phosphorus (PP) ↔️ Agricultural runoff, detergents, sewage
      Mercury (HgHg) ↔️ Industrial discharges, mining, fossil fuel combustion
    • What are three sources of lead pollution?
      Industrial discharges, lead paint, mining
    • Consumer waste is a major source of plastic pollution.
    • Oil spills are a major source of petroleum pollution.
    • Pharmaceuticals in wastewater are primarily sourced from human excretion.
    • What are two main sources of pesticides in the environment?
      Agricultural spraying, residential use
    • Plastics in the environment are solely the result of consumer waste.
      False
    • Match the pollutant with its source:
      Heavy Metals ↔️ Industrial discharges, mining
      Organic Compounds ↔️ Fuel leaks, agricultural runoff
      Pharmaceuticals ↔️ Wastewater treatment plants
    • Lead (PbPb) is released into the environment through industrial discharges, lead paint, and mining
    • Pesticides are primarily used in agricultural spraying and residential use.
    • What are three sources of plastic pollution?
      Industrial production, consumer waste, dumping
    • Petroleum-related pollution can result from oil spills, industrial discharges, and transportation
    • Match the aquatic and terrestrial pollutant with its primary source:
      Nitrogen ↔️ Agricultural runoff
      Phosphorus ↔️ Detergents
      Mercury ↔️ Industrial discharges
      Lead ↔️ Lead paint
      Plastics ↔️ Consumer waste
      Petroleum ↔️ Oil spills
    • Mercury pollution can result from fossil fuel combustion and mining activities.
    • Pollutants travel through the environment via air, water, and soil
    • How do pollutants spread in the air?
      Wind currents
    • In soil, pollutants seep into the ground, poisoning the earth and potentially reaching groundwater
    • What is an example of an acute health effect caused by pollutants?
      Respiratory issues from smog
    • Chronic health effects develop gradually over time from repeated exposure to pollutants.
    • Specific health effects target particular body systems or organs
    • Pesticides like C12H9Cl5C_{12}H_{9}Cl_{5} are used in agricultural spraying and residential areas.
    • What is the primary health risk associated with pollutants in the air?
      Respiratory issues
    • Pollutants in water pose health risks through contaminated drinking water and seafood.
    • In soil, pollutants can harm plant life and potentially reach groundwater
    • Acute health effects occur rapidly after exposure and are usually short-term
    • Chronic health effects develop quickly after exposure.
      False
    • What do specific health effects target in the body?
      Body systems or organs
    • Match the type of health effect with its description:
      Acute ↔️ Short-term, immediate effects
      Chronic ↔️ Long-term, gradual effects
      Specific ↔️ Targeted effects on body systems
    • An example of an acute health effect is respiratory issues from smog
    • Lead poisoning from contaminated water is an example of a chronic health effect.
    • What is one specific health effect of heavy metals?
      Damage to the nervous system
    • Steps to understanding the health effects of pollutants:
      1️⃣ Categorize health effects into types
      2️⃣ Identify specific examples of each type
      3️⃣ Understand targeted effects on body systems
    • Nitrogen can cause respiratory irritation and contribute to eutrophication
    • Which body system is primarily affected by mercury exposure?
      Nervous system
    • Plastics in the environment can release chemicals that lead to hormone imbalance.
    • What two organs are damaged by heavy metals?
      Nervous system and kidneys
    • Match the pollutant with its health effect:
      Nitrogen ↔️ Respiratory irritation
      Mercury ↔️ Neurological disorders
      Lead ↔️ Brain development impairment
      Pesticides ↔️ Endocrine disruption
    • Lead exposure can affect the cardiovascular system.
    • What health effect is associated with nitrogen as a pollutant?
      Respiratory irritation
    • Phosphorus as a pollutant promotes algal blooms, leading to oxygen depletion
