pollution is the presence of harmful substances in the envionment. some that are effecting or enviornment today are. piles of garbage,americans produce more houshold waste than any other nation. billions of kilograms of this waste are classified as hazordous. which means it's harmful to humans and the environment. Hazordous waste also comes from homes, old cars, paints, batteries, medical wastes, and detergents all pollute the environment. \nNuclear power plants produce electricity for millions of homes and businesses they also produce radioactive wastes, special kinds of  hazordous wastes that take hundreds of thousands of years to become harmless. These "hot" wastes can cause cancer, leukemia, and birth defects in humans. Radio active wastes can have harmful effects on all living things.\nSome pollutants affect the senses. These include bad odors and loud noises. too much noise is not just annoying but affects the ability to hear and think. \nI hope this helps you with your homework.

Have you tested the levels of pollutants that bus or car is putting out?  How about the water you drink?  Or the mountains of waste produced by the office you work at?  How far away do you live from a chemical factory? Or a nuke plant?  Where is all the garbage going that you and your family produce?  How about the food colorings and additives?\n\nAnd you're worried about some cigarette smoke?\n\n\nPULLLLLEEEEEEEEESSSSSSSEE!!\n\nPeace.

Increased traffic, which causes smog. You can also consider noise pollution, from the cars and people coming and going, and any trash or recyclables that are not handled correctly.

Not all advances in technology cause pollution. Man needs to put his mind to the types of science that work in harmony with nature.

My God!!!  Are you people really this brainwashed or are you simply selfish and stupid?!?!?!\n\nSometimes I think only 10 yo girls are answering questions on this board.\n\nOxides of nitrogen. This gas can make children susceptible to respiratory diseases in the winters.\nCarbon monoxide. CO (carbon monoxide) combines with haemoglobin to lessen the amount of oxygen that enters our blood through our lungs. The binding with other haeme proteins causes changes in the function of the affected organs such as the brain and the cardiovascular system, and also the developing foetus. It can impair our concentration, slow our reflexes, and make us confused and sleepy.\nSulphur dioxide. SO2 (sulphur dioxide) in the air is caused due to the rise in combustion of fossil fuels. It can oxidize and form sulphuric acid mist. SO2 in the air leads to diseases of the lung and other lung disorders such as wheezing and shortness of breath. Long-term effects are more difficult to ascertain as SO2 exposure is often combined with that of SPM.\nSPM (suspended particulate matter). Suspended matter consists of dust, fumes, mist and smoke. The main chemical component of SPM that is of major concern is lead, others being nickel, arsenic, and those present in diesel exhaust. These particles when breathed in, lodge in our lung tissues and cause lung damage and respiratory problems. The importance of SPM as a major pollutant needs special emphasis as a) it affects more people globally than any other pollutant on a continuing basis; b) there is more monitoring data available on this than any other pollutant; and c) more epidemiological evidence has been collected on the exposure to this than to any other pollutant. \n\nAutomotive/manufacturing pollution is much worse and (silly little girl that said otherwise...'worldtraveler') these pollutants are much more dense and concentrated than tobacco smoke.\n\nto hutches3....silly head...your feet will get your lazy butt to the grocery store and cause NO pollution.  If you are so worried about 'smoke', give up your car....that is why you have 2 feet.\n\n\nAnd, finally, to Julie B....are you freaking retarted???  Car Exhaust doesn't cause cancer and emphysema????  Of course they can!!!  If you think car exhaust is not harmful, crank up your car and shut your garage....see what happens.  \n\nIn fact, here is a good test study for you idiots.  \n\nPrior to the above suggestions (car, garage, etc...since you won't survive that one, please do it after the next suggestion) Light up an entire carton of cigarettes in a closed up garage.  sit in there for 20 minutes.....are you dead???  No??  OK, now let all the 'deadly' tobacco smoke out of the garage.  Now close the garage door again (don't really do this part, it WILL kill you.) crank up your car and sit there for 20 minutes....\n\nMy point is, clearly exhaust from a car is WAAAAAAAY more deadly than cigarettes....and I REALLY don't care if it gets you to the grocery store or not, idiot, it is much more deadly than a cigarette....\n\nPoster, thanks for allowing me to vent for few minutes about this.  Sorry I ranted so much, but idiots make me do that occasionally!!  :-)

The main way it affects it is this.  Smoke particles block up the alvioli in the lungs and that is where the exchange of oxygenated and deoxygenated blood cells take place - the more are blocked, the less oxygen can get into the bloodstream and the less oxygen gets to the body's vital organs.  Cigarettes also contains tar which also blocks up the lungs and small traces of arsenic (a poison) which is stored by the body and builds up over a period of time.  As to diseases:\n\nAsthma, Emphysema, permanently stained teeth and fingers, Gingivitis, Gangrene, chronic obstructive pulmonary disease (COPD), acute myeloid leukemia and cancers of the cervix, kidney, pancreas and stomach; abdominal aortic aneurysm, chronic bronchitis, cataracts, periodontitis and pneumonia, colorectal cancer, liver cancer, prostate cancer or erectile disfunction, increased chances of getting breast cancer, cancer of the bladder, eosophagus, larynx, lung, mouth, throat, linked to chronic lung disease, chronic heart and cardiovascular disease as well as reproductive problems. Expect to die 10 to 15 years earlier than non-smokers. \n\nHope that helps.

I assume you mean the effect on human health.  Here is a good source for information on radiation sickness at different exposure levels.\nhttp://en.wikipedia.org/wiki/Radiation_sickness

Yes, the Children's Health Study, which began in 1992, is a large, long-term, study of the effects of chronic air pollution exposures on the health of children living in Southern California. Children may be more strongly affected by air pollution because their lungs and their bodies are still developing. Children are also exposed to more air pollution than adults since they breathe faster and spend more time outdoors in strenuous activities.

Our beautiful earth is being destroyed. Thousands and thousands of trees are being cut down in short amounts of time, and trees give us the oxygen we need to survive. People are polluting the earth by littering, dumping trash into rivers, lakes and oceans. Car exhaust and smoking causes smog and makes the oxygen layer in our atmosphere thinner. If we don’t take action, our earth will end up like one big junkyard.

Air pollution is a broad term applied to all physical (particulate matter), chemical, and biological agents that modify the natural characteristics of the atmosphere.\n\nSome definitions also consider physical perturbations such as noise pollution, heat, radiation or light pollution as air pollution.[citation needed] Definitions commonly include the term harmful as a requisite to consider a change to the atmosphere as pollution.\n\nAir pollutants are classified as either primary or secondary; a primary air pollutant is one that is emitted directly to the air from a given source, such as the Carbon monoxide produced as a byproduct of combustion, whereas a secondary air pollutant is formed in the atmosphere through chemical reactions involving primary air pollutants. The formation of ozone in photochemical smog is an example of a secondary air pollutant.\n\nThe atmosphere is a complex, dynamic and fragile system. Concern is growing about the global effects of air pollutant emissions, especially global warming. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health.

When toxic substances enter lakes, streams, rivers, oceans, and other water bodies, they get dissolved or lie suspended in water or get deposited on the bed. This results in the pollution of water whereby the quality of the water deteriorates, affecting aquatic ecosystems. Pollutants can also seep down and affect the groundwater deposits.\n\nWater pollution has many sources. The most polluting of them are the city sewage and industrial waste discharged into the rivers. The facilities to treat waste water are not adequate in any city in India. Presently, only about 10% of the waste water generated is treated; the rest is discharged as it is into our water bodies. Due to this, pollutants enter groundwater, rivers, and other water bodies. Such water, which ultimately ends up in our households, is often highly contaminated and carries disease-causing microbes. Agricultural run-off, or the water from the fields that drains into rivers, is another major water pollutant as it contains fertilizers and pesticides.

Fossil fuel power plants can emit many harmful pollutants, ranging from Nitrogen Oxides and particulates to heavy metals & mercury.\n\nThe radiation from the sun's nuclear fusion is what gives us solar energy, but it can also cause skin cancer.\n\nUse of solar energy generally requires using materials that have caused pollution as a byprodouct of their manufacture.
