  3. 3.  From television and radio waves, to mobile phoneemissions and a thousand and one other sources weare being bombarded by a constantstream of electronic pollution This is the pollution caused by electronic devices. The main problem we face-1) e-waste2) electronic radiations
  4. 4. E-WASTE The unethical way of discarding used electronicequipments in the form of waste is termed as E-Waste..these wastes are non biodegradable

  8. 8.  Sources of e-waste in China:( domesticallygenerated) ƒ 710 million home electronic appliances near endof life span. ƒ Chinese demand for electronics and electricalequipment continues to surge. ƒ China generates roughly 1 million tons of e-wasteannually since 2003, and the quantity is increasing. ƒ Pressure from dumping by developed countries. ƒ Zeal from anarchic private sector in China ƒ China’s thirst for materials as world factoryCHINA :-
  9. 9. CASE STUDY :- E-WASTEBANGALORE Ewaste has been a problem of great concern not only for the government but also for thepublic due to their hazardous material contents. For this reason the management andrecycling of E-waste was assessed in the city of Bangalore (India) based on rapid growingwaste stream, waste valuable resources, hazardous substances and low recycling rate. Thehierarchy of treatment of E-waste encouragesreuse of whole equipment first,remanufacturing and upgradation, then recovery of materials by recycling techniques, andas a last resort, disposal by incineration and land filling. This study was conducted in themonth of March, 2009 in the Banglore city of India. Bangalore is the informationtechnology hub of India having more than 1700 IT companies generating 8,000 tonnes ofE-waste annually.For this study the tracer item chosen was the personal computer (PC). Atracer item in this context stands for an electrical or electronic item which is surveyedalong its whole life span, from the cradle to the grave. From the result it was found that with proper management the level of e-waste in the citydrastically reduced. All in all E-waste management in Bangalore has moved forward inmany ways and can now serve as a model for other cities and state in the country.
  10. 10. ELECTRONIC RADIATIONS - Most home electronics devices emit electronicradiation. Below is a list of equipment that could becausing problems in your health. Cordless Phones Cordless Baby Alarms Cellular Phones Wireless Internet Networks Laptopes
  11. 11. EFFECTS OF EMF :- EM radiation to serious diseases like cancer, Alzheimer’s, Parkinson’s and others. Some of the potential side effects of exposure to electromagnetic radiation: Blurry Vision Headaches Nausea Fatigue Neck Pain Memory Loss Leukemia Rare Brain Cancers Enzyme Changes That Affect DNA Birth Defects Changes In Metabolism Increased Risk For Alzheimer’s Disease Increased Risk For Heart Conditions Neurological Hormone Changes Linked Impaired Brain Function And More…
  12. 12. APPROXIMATELY 20-80% OF THE CELL PHONERADIATION FROM YOUR MOBILE DEVICE’S ANTENNAPENETRATES UP TO 2 INCHES INTO THE ADULT BRAIN.
  13. 13. EXPOSURE OF RADIATIONS IN DIFFERENTCOUNTRIES….
  14. 14.  Erection of tower shall not be allowed within aradius of 100 meter from residential building,school and hospital. In India, we have adopted radiation norms given byICNIRP guidelines of 1998 for safe power forGSM900 transmitting band (935-960 MHz), power density is 4.7W/m2 and for GSM1800 transmitting band (1810-1880MHz), it is 9.2W/m2 Emission should be non-ionising . towers should not be f high density/
  15. 15. CASE STUDY :- TOWER RADIATIONSGERMANY (Eger H, 2004) The aim of this study was to examine whether people living close to cellulartransmitter antennas were exposed to a greater risk of becoming ill withmalignant tumors. The researchers found that the proportion of newlydeveloping cancer cases was significantly higher among those patients who hadlived within 400 meters from the cellular transmitter site during the past 10years, compared to those patients living further away. They also found that thepatients fell ill on average 8 years earlier. After five years of operation of thetransmitting installation, the relative risk of getting cancer had increased by 3-fold for the residents of the area near the installation, compared to theinhabitants outside the area. Breast cancer topped the list, and the average ageof contracting this disease was considerably lower, 50.8 years compared to69.9 years for the people living in the outer area. Cancers of the prostate,pancreas, bowel, skin melanoma, lung and blood cancer were all increased.
  16. 16. HYDERABAD :-From only a single city, hyderabad(GHMC) has found 4566 cell towers Out ofwhich more than 2000 cell towers has been illegally built and approx-568 towersare of high densitysituated in Circle- 10 areas like Khairatabad, Punjagutta,Banjara Hills. Several towers do not have structural stability and were posing danger not onlyto inmates of buildings where they were erected but also their neighbourswhich is causing a serious problems blindly. After a lot of serious concerns and complaints, the corporation has decided totake action against faulty telecom companies like dismantling cell towers ifthey do not pay Rs one lakh fee and get them regularised immediately. In June, the AP high court, while disposing cases on illegal cell towers, saidthat the towers should be erected by taking permission from the corporation.
  17. 17. 2.3CASESTUDYOFUSHAKIRANBUILDING,MUMBAIthe news reported in Midday,Mumbai dated Jan. 3, 2010, whichstated - “Mumbais swanky UshaKiran building says thefour cancer cases there could belinked to mobile towers installed onthe facing VijayApartments”. The picture taken fromthe Usha Kiran building of theseveral antennas installed onthe seventh floor of Vijay Apartmentsis shown in Fig. 2. People living inthe 6th, 7th and 8thfloor in the opposite building will getmaximum radiation as they are in themain beam direction.People living on the other floors willreceive lesser radiation as beammaxima is reducedconsiderably as can be observed fromvertical radiation pattern. In thehorizontal direction again,people living in the front side of theantenna will receive much higherradiation compared topeople living in the back side ofantenna.
  18. 18. can we?no, we can`tbut, we can takemeasures
  19. 19. MEASURES Use hands-free to decrease the radiation to thehead. Keep the mobile phone away from the body. Do not use telephone in a car without an externalantenna. Use mobile radiation tracking apps have beendeveloped to help to mitigate exposure.
