It can have harmful effects on plants, aquatic animals, and infrastructure through the process of wet deposition Acid rain is caused by emissions of compounds of ammonium, carbon, nitrogen, and sulfur which react with the water molecules in the atmosphere to produce acids History Since the Industrial Revolution, emissions of sulfur dioxide and nitrogen oxides to the atmosphere have increased In 1852, Robert Angus Smith was the first to show the relationship between acid rain and atmospheric pollution in Manchester, England Though acidic rain was discovered in 1852, it was not until the late 1960s that scientists began widely observing and studying the phenomenon The term "acid rain" was generated in 1972 Canadian Harold Harvey was among the first to research a "dead" lake Public awareness of acid rain in the U.S increased in the 1970s after the New York Times promulgated reports from the Hubbard Brook Experimental Forest in New
Miina Härma Gymnasium Acid Rain Report Compiler: Teisi Timma 8a Teacher: Esther Linask Tartu 2009 Acid Rain Acid rain is rain consisting of water droplets that are unusually acidic because of atmospheric pollution - most notably the excessive amounts of sulfur and nitrogen released by cars and industrial processes. Acid rain is also called acid deposition because this term includes other forms of acidic precipitation such as snow. Acidic deposition occurs in two ways: wet and dry. Wet deposition is any form of precipitation that removes acids from the atmosphere and deposits them on the Earth's surface. Dry deposition polluting particles and gases stick to the ground via dust and smoke in the absence of precipitation. This form of deposition is dangerous however because
Acid Rain Acid rain is any precipitation that is unusually acidic. It possesses elevated levels of hydrogen ions(it has low pH level). Acid rain is caused by emissions of carbon dioxide, sulfur dioxide and nitrogen oxides, which react with water molecules. Distilled water(doesn't contain CO 2), has pH level 7. Liquids with pH level less than 7 are acidic, liquids with pH level greater than 7 are alkaline. Unpolluted rain has a pH level over 5.7, so it is slightly acidic. Affected areas Places significantly impacted by acid rain around the globe include most of eastern Europe from Poland northward into Scandinavia, the eastern

Acid rains This morning you contributed to atmosphere desolation H ow it is formed? Acid rain is formed by burning fossil fuels such as coal, natural gas, and oil. Gases of acid rain Sulfur dioxide and nitrogen oxide are the gases that form the acid rain. Our health and acid rain Acid rain effects even our health. Breathing and lung problems in people (especially those with asthma) and have been linked to acid air pollution. Some things that you can do to make acid rain less of a problem are: Only run the dishwasher and washing machine with a full load. Turn off the lights in empty rooms or when you will be away from home. Turn off the hot water tank when you will be gone for a long period of time. Don't use your air conditioner or heater as much. Install fluorescent light bulbs instead of incandescent light bulbs.

Acid rain is rain or any other form of precipitation that is unusually acidic. It can have harmful effects on plants, aquatic animals, and infrastructure through the process of wet deposition. Acid rain is caused by emissions of compounds of ammonium, carbon, nitrogen, and sulfur which react with the water molecules in the atmosphere to produce acids. Governments have made efforts since the 1970s to reduce the production of sulfuric oxides into the Earth's atmosphere with positive results Since the Industrial Revolution, emissions of sulfur dioxide and nitrogen oxides to the atmosphere have increased.[2][3] In 1852, Robert Angus Smith was the first to show the relationship between acid

countries have now banned such behavior, it continues to go on today. As the world has industrialized and its population has grown, the problem of water pollution has intensified. The simple fact that millions of people live along coastlines and near rivers means that these bodies of water are likely candidates for heavy and destructive pollution. It is hard to know now what our oceans will look like in the future. Just how damaged they will be by pollution is uncertain. Acid rain The term acid rain refers to what scientists call acid deposition. It is caused by airborne acidic pollutants and has highly destructive results. Scientists first discovered acid rain in 1852, when the English chemist Robert Agnus invented the term. From then until now, acid rain has been an issue of intense debate among scientists and policy makers. Acid rain, one of the most important environmental problems of all, cannot be seen.

1990ndad See kümnend ei lisanud popmuusika vooludesse eriti midagi uut. Arenesid edasi need meelelahutusmuusika suunad, mis tekkisid 80.aastate keskel ja lõpus (house, hip hop, techno, grunge). 90.aastatel hakkasid popmuusika voolud kiiresti paljunema, tekitades mitmeid alaliike (acid house, trip-hop, dub jt.). Uusi alaliike tekkis ka traditsiooniliste rock-muusika suundadele. DISKORID Uueks nähtuseks võib lugeda aga DJ-de osatähtsuse suurt kasvu. Pillimeeste-muusikute kõrvale tõusid diskorid, kes vallutasid suure osa maailma popmuusikaturust. Põhjuseks võib olla klubikultuuri ning klubipidude, reivide populaarsuse tõusus. Sellel kümnendil selgus, et tänu arvutitehnikale polegi popmuusika tegemiseks vaja ise pillimees olla.

ENVIRONMENTAL PROBLEM The term acid rain refers to what scientists call acid deposition. It is caused by airborne acidic pollutants and has highly destructive results. Scientists first discovered acid rain in 1852, when the English chemist Robert Agnus invented the term. From then until now, acid rain has been an issue of intense debate among scientists and policy makers. Acid rain, one of the most important environmental problems of all, cannot be seen. The invisible gases that cause acid rain usually come from automobiles or coal-burning power plants. Acid rain moves easily, affecting locations far beyond those that let out the pollution. As a result, this global pollution issue causes great debates between countries that fight over polluting each other's environments. For years, science studied the true causes of acid rain. Some scientists concluded that human production was primarily responsible, while others cited natural causes as well
Aim of the work The determination of the concentrations of acid and base solutions through titration. Used compounds HCl solution with an unknown concentration. NaOH solution with a known accurate concentration, indicators phenolphthalein (ff/pp) and methyl red (mp/mr). Equipment Conical flasks (250 cm3), 2 burettes (25 cm3), pipette (10 cm3). Procedure A. Determining the concentration of a hydrochloric acid solution through titration 1. To determine the concentration of the acid solution take the NaOH solution with a known concentration (the standard solution) and pour it into the burette (α in figure 2.2). See that there are no air bubbles near the tip. Fill the burette until the 0-point of the scale. When measuring the level of the solution keep your eyes at the same level with the liquid level. The lower edge of the liquid level has to be at the 0 calibration mark (see figure 2.1).

Sauerkraut Sauerkraut is finely shredded cabbage that has been fermented by various lactic acid bacteria, including Leuconostoc, Lactobacillus, and Pediococcus. It has a long shelf-life and a distinctive sour flavor, both of which result from the lactic acid that forms when the bacteria ferment the sugars in the cabbage. It is therefore not to be confused with coleslaw, which receives its acidic taste from vinegar. People of Estonia like sauerkraut very much. They definitely a great dish for Christmas, because it`s really good to eat it with potatoes or something like that. To make sauerkraut yourself you need to have: 1 kg sauerkraut, 700 g slightly salted pork, 100 g barley grits, 2 tomatoes, salt. This is how you can do it: Boil

Often leads to bladder cancer. Aniline was tested on animals, but in mice was observed no increase in tumour incidence, in rats, it produced fibrosarcomas, sarcomas and haemangiosarcomas of the spleen and peritoneal cavity. 4. Behavior in the wild Not found in nature. If appears, starts oxidation. In reactions localized at nitrogen or more commonly results in the formation of new C-N bonds. In alkaline solution, azobenzene results, whereas arsenic acid produces the violet-coloring matter violaniline. Chromic acid converts it into quinone, whereas chlorates, in the presence of certain metallic salts (especially of vanadium), give aniline black. Hydrochloric acid and potassium chlorate give chloranil. Potassium permanganate in neutral solution oxidizes it to nitrobenzene, in alkaline solution to azobenzene, ammonia and oxalic acid, in acid solution to aniline black.

air that we breathe, becomes dangerous to our health. The ozone layer around the Earth, there is a special type of oxygen called ,,ozone". Ozone is important because it stops ultraviolett radiation from the sun. Many aerosol sprays and factories destroy ozone and they have made a very big hole in the ozone layer. This means that too much ultraviolet radiation now enters the Earth. This is very dangerous because it can cause cancer. Poisonous chemicals also cause acid rain, that destroyes plants, rivers, lakes and buildings. Acid rain can travel thousands of miles, so pollution in one country can become acid rain for another country. So how to avoid the worst? Lets talk about cars, which are the main means of transport in our everyday life, they are useful and take us to the place, where we want to go. But lets be honest, they have also negative aspects. Like heavy traffic in the morning, while you are

Pine oli kõigest 22, kui 1987. aastal ilmus tema debüütalbum Journey To The Urge Within, mis äratas kohe tähelepanu . Järgnesid Destiny' s Song ja The Vision Tale ning üheksakümnendate aastate esimesel poolel Closer To Home, Within The Realms of Our Dreams, The Eyes of Creation. 1995. aastal sidus Courtney Pine ennast plaadifirmaga Talkin' Loud, ilmutas albumi Modern Day Jazz Stories ning ei pahandanud, kui tema muusika kohta kasutati väljendit acid jazz. Just siis algas tema koostöö DJ-de Pogo ja Sparkiga. Plaat sai hulga kriitikat ning Briti mainekamad drum'n'bass-artistid 4 Hero ja Roni Size asusid Courtney Pine'i muusikat remiksima. 1996. aastal omistati plaadile mainekamaid inglise muusikaauhindu Mercury Prize. 1997. aasta sügisel ilmunud Underground tõstis Courtney Pine'i nime moodsa jazzmuusika eliidi seas veelgi rohkem esile. Just selle laine muusikat esitas ta 1998.aasta Jazzkaarel, üllatades suuresti meie publikut

much more environment friendly. The one that we do the most is leaving rubbish around that doesn`t turn into compost. We should save energy by just turning off the electic appliances when we don`t use them. When going to the store we should bring our own canvas bags or just reuse old plastic bags. Reducing the damage to the environment would help our plants and animals from dying out and not to make any acid rains. Lots of people don`t take this stuff seriously and make wrong decisions in their everyday life. https://docs.google.com/document/d/1IA0iCRB5q_YX44RM8BK40-NnN0UZBes9uzsvyJwFwCw/edit 1/1
How can we reduce air pollution level in cities? The air pollution levels are extremely high in cities, but how can people change this situation? Cars and big factories emit lots of deleterious gases into the air, for example carbonic acid gas, cities are not healthy places to live anymore. Firstly, we should using the public transport. Everybody can walk and bicycle instead of driving cars. Vehicles emit a lot of harmful gases into the air. Every family member does not need his or her own car. One car for the whole family would minimise the number of cars in cities and air pollution levels will come down. Secondly, people have to recycle. It would help reduce factories work. It will emit less harmful gases into the air. Finally, we should plant more trees in cities and also create more national parks. They produce oxygen. In conclusion, there are many ways to make cities better...

may not have enough resources, beacuse right now we are using too much. Secondly, there is a huge amout of waste and pollution. Clean air is our most valuable resource, but it is getting more and more polluted, in the same way as the water. For example, the pollution of water kills hundreds of thousands of birds and water animals. As a result of pollution , there are holes in the ozone layer, which in its turn loses some of its protection. Pollution is also the cause of acid rain, which damages the forests. In conclusion, we cannotonly consider with our needs, we have to think more broadly. In the future our children will need the same resources in the same way as we do. If we do not consider with the others' needs, and increase the overconsumption even more, then we will finally destroy our planet.
