Effects of Pollution on Animals - Air Pollution

  • Acid rain  destroys fish life in lakes and streams
  • Excessive ultraviolet radiation may cause skin cancer in wildlife
  • Ozone in the lower atmosphere may damage lung tissues of animals

Effects of Pollution on Animals - Water Pollution

  • Nutrient pollution (nitrogen, phosphates etc) causes overgrowth of toxic algae eaten by other aquatic animals, and may cause death.
  • Chemical contamination can cause declines in frog biodiversity and tadpole mass.
  • Oil pollution can negatively affect development of marine organisms can also cause gastrointestinal irritation, liver and kidney damage, and damage to the nervous system
  • Mercury in water can cause abnormal behavior, slower growth and development, reduced reproduction, and death
  • Persistent organic pollutants (POPs) may cause declines, deformities and death of fish life
  • Too much sodium chloride (ordinary salt) in water may kill animals

Effects of Pollution on Animals - Soil Pollution 

  • Can alter metabolism of microorganisms and arthropods in a given soil environment; this may destroy some layers of the primary food chain, and thus have a negative effect on predator animal species
Small life forms may consume harmful chemicals which may then be passed up the food chain to larger animals; this may lead to increased mortality rates and even animal extinction.
