  3. 3. INTRODUCTIONPollution fromindustry, households,vehicles and farmscauses healthproblems for peopleand for animals. It canaffect both the air andthe quality of water inrivers, lakes andseas.
  4. 4. INDUSTRIAL POLLUTIONIndustrial pollution ispollution which can bedirectly linked withindustry, in contrast toother pollutionsources. This form ofpollution is one of theleading causes ofpollution worldwide.
  5. 5. Where do industrial pollutantscome from ?Industrial pollutants are pollution andwaste by product directly connectedwith industrial manufacturing.Industrial pollutant represents theleading world wide cause of pollutionin general and probably the most toxicto all life and nature, becauseindustrial pollutants are produced insuch a large capacity frommanufacturing worldwide and because
  6. 6. Industrial pollutionThere are number of forms of industrialpollution
  7. 7. Water pollutionOne of the most common is waterpollution, caused by dumpingof industrial waste into waterways, orimproper containment of waste, which
  8. 8. Sources of water pollution
  9. 9. Effects of water pollutionIn India, water pollution due to industrial wastesand sewage has been assuming menancingproportions. Large lakes and large stretches of mostof the rivers in India have water which is unsafe fordrinking purpose. Survey of industrialized zonesshow that even ground water has become unfit fordrinking due to high concentration of toxic metalsand chemicals along with bacteriologicalcontaminationill effects of water pollutionLead More than 400 mg of lead in human body can cause braindamage, vomiting, loss of appetite, damage of kidney etc.Manganese Mn is essential for mammals but in concentration greaterThan 100 ppm, is toxic, and causes , fever, muscles fatigue, eye blindness.Nickel More than 30 mg may cause changes in muscle, brain, lungs, liver,kidney and can also cause cancer, paralysis and even death
  10. 10. Air pollutionIndustries can also cause airpollution.Industrial pollution can alsoimpact air quality, as it giveout chemical components andgases in the air
  11. 11. Sources of air pollution
  12. 12. Effects of air pollution• Acid rain is an effect of air pollution. Acid rain can poisendrinkwater, ruin the harvest from farmers, damage aquaticlife and erode buildings.• Air pollution can cause cancer, headache, decreased musclecoordination,worse sight etc.• Childrens have more problems with air pollution than adults.• Smoke come out from the factories is very dangerous for thosewho lives on thisearth. It contains lots of harmful chemicals which effects thebody badly.• Different diseases are caused with this smoke like asthma,lung disease, heart
  13. 13. Soil pollutionSoil pollution is caused by humanactivitiesand their misuse of landresources.It occurs when waste is notdisposed properly. Health hazarddisposal of urban andindustrial wastes, exploitation ofminerals, and improper use of soilby inadequate agriculturalpractices are a few factors.Industrialization is the majorCause of soil pollution.
  14. 14. Sources of soil pollution
  15. 15. Effects of soil pollution• Dangerous chemicals from industries enteringunderground water• Ecological imbalance• Release of pollutant gases• Release of radioactive rays causing health problems• Increased salinity• Reduced vegetation
  16. 16. Global warmingGlobal warming is one of themost common and seriousconsequences of industrialpollution. The emission ofvarious greenhouse gases suchas CO2, methane ,increases theoverall temperature of theearth, resulting in globalwarming.
  17. 17. Government Functions ToControl IndustrialPollution• Pollution Assessment• Pollution Control Regulatory functions• Laying Down Standards for Effluent and Emissions• Research & Development including setting up of thedemonstration plants• Environment Awareness Programme• Advisory Role• Establishment Laboratories
  18. 18. Government StrategiesTo Control IndustrialPollution• Take up highly polluting large and medium industries, most grosslypolluted areas of the State and grossly polluted river stretches to bedealt with on priority basis for control of pollution.• Promotional measures and assistance through incentives, guidelines,development of cost effective technologies and putting up ofdemonstration plants.• Persuasion of industry / local bodies to take preventive measures for thecontrol of pollution.• Strengthening of capacities for pollution control through training andlaboratory development and strengthening of man power andinfrastructure.
  19. 19. Government ActivitiesTo Control IndustrialPollution• It carries out the monitoring of the Water quality of all the four rivers ofthe State viz. Satluj, Beas, Ravi & Ghaggar through 37 monitoringstations• It monitors  the groundwater quality in the major industrial towns ofLudhiana, Jalandhar, Amritsar, Nangal etc.• It carries out the monitoring of the quality of ambient air of Ludhiana,Jalandhar, Amritsar, Patiala, Mandi Gobindgarh & Nangal through 22permanent air monitoring stations.• The Board advices, guides, encourages, persuades & helps the industry inputting up effluent treatment plants and air pollution control devices tocontrol pollution and in taking other measures to prevent or reducepollution.
  20. 20. Techniques• recycling• reusing• reducing• mitigating• preventing• compost
  21. 21. Pollution control• Pollution control is a term used in environmental management. It means the control of emissions and effluents into air, water or soil. Without pollutioncontrol, the waste products from consumption, heating,agriculture, mining, manufacturing, transportation and otherhuman activities, whether they accumulate or disperse, willdegrade the environment. In the hierarchy of controls, pollution prevention and waste minimization are moredesirable than pollution control. In the field of land development, low impact development is a similartechnique for the prevention of urban runoff.
  22. 22. Pollution controldevices• Dust collection systems– Baghouses– Cyclones– Electrostatic precipitators• Scrubbers– Baffle spray scrubber– Cyclonic spray scrubber– Ejector venturi scrubber– Mechanically aided scrubber– Spray tower– Wet scrubber
  23. 23. • Sewage treatment– Sedimentation (Primary treatment)– Activated sludge biotreaters (Secondary treatment; also used forindustrial wastewater)– Aerated lagoons– Constructed wetlands (also used for urban runoff)• Industrial wastewater treatment– API oil-water separators[15][35]– Biofilters– Dissolved air flotation (DAF)– Powdered activated carbon treatment– Ultrafiltration• Vapor recovery systems• Phytoremediation
  24. 24. SUGGESTIONS• Stop smoking or at least follow the “No Smoking” sign.• Never use open fires to dispose of wastes.• Industries should use fuel with lower sulphur content.• Industries should monitor their air emissions regularlyand take measures to ensure compliance with theprescribed emission standards.• Industries should strictly follow applicable governmentregulations on pollution control.• Take very good care of your pets and their wastes.• Do not cause loud noises and unwanted sounds to avoidnoise pollution.• Have a proper waste disposal system especially for toxicwastes
