The document discusses various forms of ICT pollution, including space pollution, energy consumption, thermal pollution, radiation, and light pollution. It highlights the environmental and health risks associated with these types of pollution, such as the increase in energy consumption from ICT, harmful thermal effects on water ecosystems, and the negative impact of radiation on wildlife and human health. Additionally, it emphasizes the effects of light pollution on sleep and circadian rhythms, as well as the overall degradation of natural environments.

- 9. White Is the color of milk and fresh snow, the color produced by the combination of all the colors of the visible spectrum. Risks Black Is the color of coal, ebony, and of outer space. It is the darkest color, the result of the absence of or complete absorption of light.
- 10. Energy Consumption ⊙ 5% of the worldwide primary energy consumption is caused by ICT (production, use and end-of-life) ⊙ Expected: 10% in the next 10 to 15 years (if no precautions are made) ⊙ 9% of ICT consumption is caused by the wireless access networks. ⊙Energy consumption within wireless access networks. ⊙ 10% consumed by user terminals such as mobile phones, laptops, etc. ⊙ 90% consumed by base stations.

- 12. ⊙Addition of excess undesirable heat to water that makes it harmful to man , animal and aquatic life ⊙ After the water is used, it is put back into a water supply at 9-20oC warmer. Thermal Pollution Cooling tower showing evaporating water at Power Station in , United Kingdom
- 13. ⊙ Thermal Shock: A sudden thermal shock can result in mass killings of fish, insects, plants or amphibians. ⊙ Oxygen dissolved in water is decreases. ⊙Causative agent of Global warming . Risks
- 14. ⊙This is the pollution due to abnormal radiation in the environment. This occurs due to use of radioactive elements from atomic energy stations. Radiation
- 15. ⊙ Researches tells teenagers have four to five times more disease in less than 10 years. Exposure to radiation from cellphones. ⊙ It has been observed that birds like sparrows and insects like honey bees seem to be getting extinct from human areas due to these radiations. Risks
- 16. ⊙ Also known as Photo pollution or luminous pollution. ⊙ It is excessive or obtrusive artificial lights. Light Pollution A comparison of the view of the night sky from a small rural town (top) and a metropolitan area(bottom). Light pollution dramatically reduces the visibility of stars.
- 17. ⊙ Light pollution effects especially disturbing to sleep of humans, birds and other animals. This might some times affect the natural body rhythm or circadian clock. ⊙ Prolong exposure to excessive light may lead to vision problem. Risks
