  2. PENCEMARAN LINGKUNGAN Polusi atau pencemaran lingkungan adalah masuknya atau dimasukkannya makhluk hidup, zat energi, dan atau komponen lain ke dalam lingkungan, atau berubahnya tatanan lingkungan oleh kegiatan manusia atau oleh proses alam sehingga kualitas lingkungan turun sampai ke tingkat  tertentu yang menyebabkan lingkungan menjadi kurang atau tidak dapat berfungsi lagi sesuai dengan peruntukannya (Undang-undang Pokok Pengelolaan Lingkungan Hidup No. 4 Tahun 1982). Suatu zat dapat disebut polutan apabila:1. jumlahnya melebihi jumlah normal2. berada pada waktu yang tidak tepat3. berada pada tempat yang tidak tepat Sifat polutan adalah:1. merusak untuk sementara, tetapi bila telah bereaksi dengan zat lingkungan tidak merusak lagi 2. merusak dalam jangka waktu lama. Contohnya Pb tidak merusak bila konsentrasinya rendah. Akan tetapi dalam jangka waktu yang lama, Pb dapat terakumulasi dalam tubuh sampai tingkat yang merusak.

MODEL EKOSISTEM Solar Radiation Sun provides energy for plant photosynthesis Climate Amount of solar radiation varies with latitude & hence effects climate. solar radiation also power weather systems Volcanic activity ,mountain, ranges etc. can also affect climate Vegetation Animals Climate interacts with geology in soil formation provides water for solar climate. Soil provides water & nutrients for plants together with a physical base in which plants can root themselves. Geology Soil Plants provides food for animals Animals alter vegetation by browsing & grazing. Human have significantly altered vegetation patterns through modification for agriculture. Vegetation gives off water vapour who helps to stabilize the climate of the earth. Climate restricts the type of plants & animals that can survive in a particular ecosystem. Water & temperature are two main climate controls. Dead plants & animals decomposes & return nutrients to the soil. Nutrients are also returned to the soil through animal excrement.

  17. Pencemar Udara dan dampaknya thd kesehatan manusia • Particulate Matter • Dust and smoke particles cause irritation of the respiratory tract and produce bronchitis, asthma and lung diseases. • Dust and smoke function as nuclei for condensation of water vapors and produce smog which attract chemicals like SO2, H2S, NO2,etc. Smog not only reduce visibility but is also harmful due to its contained chemicals. Partikel debu dalam emisi gas buang terdiri dari bermacam-macam komponen, dapat berbentuk padatan dan berbentuk cairan yang mengendap dalam partikel debu. Pada proses pembakaran debu terbentuk dari pemecahan unsur hidrokarbon dan proses oksidasinya. Dalam debu tersebut terkandung debu sendiri dan beberapa kandungan oksida-logam. Dalam proses paparan selanjutnya di atmosfir, kandungan metal dan debu tersebut membentuk partikulat. Beberapa unsur kandungan partikulat adalah karbon, SOF (Soluble Organic Fraction), debu, SO4, dan H2O. Sebagian partikulat keluar dari cerobong pabrik sebagai asap hitam tebal, tetapi yang paling berbahaya adalah butiran-butiran halus sehingga dapat menembus bagian terdalam paru-paru.

  18. SMOG Smog is the combination of smoke and fog. It is a man made air pollutant in urban areas. The term smog was coined by H.A.Des Voeux There is always a lot of controversy anytime longstanding federal regulations are changed. This time, the uproar came because the Environmental Protection Agency announced plans to increase the stringency of national air quality standards regarding nitrogen dioxide (NO2) emissions. NO2 forms quickly from the emissions of cars, trucks, buses, power plants, and off-road equipment. In addition, the compound also contributes to the formation of ground-level ozone (also known as smog), and fine particle pollution, which is linked with a number of adverse effects on the human respiratory system.

  19. Types of Smog Photochemical Smog Photochemical smog is a type of air pollution caused by nitrogen oxide, hydrocarbons and sunlight. Nitrogen oxide is commonly produced from the internal combustion of engines. Photochemical smog is often prevalent in some of the sunnier U.S. cities, such as Los Angeles. This smog can have ill effects on the body and cause coughing, heart palpitations, pneumonia and even lung cancer. Read more: The Different Types of Smog | eHow.comhttp://www.ehow.com/list_6950223_different-types-smog.html#ixzz21laFkEG3 Industrial Smog Sulfurous Smog Sulfurous smog results from a high concentration of sulfur oxides being released into the air, because of burning fossil fuels. This type of smog is prevalent in London and is sometimes referred to as "London smog." While the burning of coal is the major reason why sulfur oxides are released into the air, the other causes stem from the production of crude oil and metallic ore. Sulfurous smog had been known to cause respiratory problems and can be a particular concern for those who have asthma.

  22. PENCEMAR UDARA Natural Pollutants: The pollution which comes out from natural sources such as forest fires volcanic eruption decomposition of organic matter & natural radioactivity. Secondary pollutants :These result from chemical reactions between two or more air components. Primary Pollutants: Harmful chemical that directly enters the air as a result of human activity. These are deforestisation burning of fossil fuel industrialization warfare etc. Formation of secondary pollutants 2SO2+O2 2SO3 2SO3+H2O H2SO4 (Secondary pollutant) Air pollution causes widespread damage to ecosystems Posted: July 22, 2008 in environment There is a lot of focus on CO2 when it comes to public awareness about climate change. Apart from CO2 though not being the only factor contributing to it, there is also very little awareness of the effects of air pollution on terrestrial environments, such as lakes, rivers, fauna and flora. The Cary Institute of Ecosystem Studies and The Nature Conservancy in the US has produced the first major research analysing  large-scale effects that four air pollutants are having across a broad range of habitat types. The four pollutants assessed were sulfur, nitrogen, mercury, and ground-level ozone, largely originating from smokestacks, tailpipes, and (of course!) agricultural operations. While initially airborne, these pollutants eventually return to the earth surface, where they contaminate the soil and water. They often travel long distances before reaching the ground Diunduh dari : http://isiria.wordpress.com/2008/07/22/air-pollution-causes-widespread-damage-to-ecosystems/.

  23. TANTANGAN LINGKUNGAN • Green house effect: Increasing global temperature. Scientists predicting that earth's temperature will increase by 3-40C by year 2030 if the pollution continues to increase at the same pace. • Ozone depletion: As ozone layer in the upper atmosphere absorbs incoming harmful ultraviolet radiation but it is now getting thinner & more UVs are reaching in to earth creating different disease like cancer& eye problems. • Photochemical smog: In 1952 London was covered by smog for 10 days .This smog was caused by fog, smoke, ash,& SO2 plus NO2.Sunlight played a great role in the formation of this smog .Though deaths occurring at that time were not directly attributed to the smog later statistics confirmed that 6,000 more people. Acid rain: is caused by oxides of nitrogen & sulphur.It increases acidity of soil & effects the growth of trees & plants. The majestic monument Taj Mahal in India is also affecting by this. Air pollution is a complex problem. Emissions of sulfur dioxide (SO2) and nitrogen oxide (NOx) gases from smokestacks and vehicles react in the atmosphere to form sulfate (SO4) and nitrate (NO3) particles as well as sulfuric and nitric acids in clouds and rain. Mercury (Hg) is also emitted to the atmosphere from coal burning and incinerators. Agricultural activities contribute to the nitrogen pollution problem by releasing ammonia (NH3). All of these gases, particles and dissolved chemicals can be deposited to natural ecosystems downwind of the sources. Nitrogen can accumulate in ecosystems and cause nutrient imbalances, while acid precipitation can strip important nutrients such as calcium (Ca) from the soil and mobilize toxic metals such as aluminum (Al). Acid and aluminum harm trees in the forest and fish and other aquatic animals in streams and lakes.

  28. Definisi Air pollution may be defined as the presence in the air (outdoor atmosphere) of one or more contaminants or combinations thereof in such quantities and of such durations as may be or tend to be injurious to human, animal or plant life, or property, or which unreasonably interferes with the comfortable enjoyment of life or property or conduct of business. Air Pollution Control Measures The main air pollutants discharged from a thermal plant are sulfur oxide (SOx), nitrogen oxide (NOx), and soot and dust. We are making efforts to control emissions through fuel measures including the use of high-quality fuel and the facility improvement measures including the installation of denitrification facilities, electrostatic precipitators, and flue gas desulfurization facilities, as well as through the complete combustion management while seeking prevention of air pollution by implementing the operation measures such as monitoring of emission sources.

  29. Pencemar (Polutan) Udara Pencemaran udara diartikan sebagai adanya bahan-bahan atau zat-zat asing di dalam udara yang menyebabkan perubahan susunan (komposisi) udara dari keadaan normalnya. Kehadiran bahan atau zat asing di dalam udara dalam jumlah tertentu serta berada di udara dalam waktu yang cukup lama, akan dapat mengganggu kehidupan manusia. Apabila keadaan seperti itu terjadi maka udara dikatakan telah tercemar. “Polutan” is a substance or effect dwelling temporarily or permanently in the air , which adversely alters the environment by interfering with the health, the comfort, or the food chain, or by interfering with the property values of people. A pollutant can be solid (large or sub-molecular), liquid or gas . It may originate from a natural or anthropogenic source (or both). It is estimated that anthropogenic sources have changed the composition of global air by less than 0.01%. However, it is widely accepted that even a small change can have a significant adverse effect on the climate, ecosystem and species on the planet. Examples of these are acid rain, ozone in the lower atmosphere, and photochemical smog. Diunduh dari : http://ultrawomen.wordpress.com/….. 9/11/2012.

  30. Pencemar Hidrokarbon KARAKTERISTIK HIDROKARBON Struktur Hidrokarban (HC) terdiri dari elemen hidrogen dan karbon dan sifat fisik HC dipengaruhi oleh jumlah atom karbon yang menyusun molekul HC. HC merupakan pencemar udara yang dapat berbentuk gas, cairan dan padatan. Semakin banyak jumlah atom karbon, senyawa HC ini cenderung berbentuk padatan. Hidrokarbon dengan kandungan unsur C antara 1-4 atom karbon akan berbentuk gas pada suhu kamar, sedangkan kandungan karbon lebih dari 5 akan berbentuk cairan dan padatan. HC yang berupa gas akan tercampur dengan gas-gas hasil buangan lainnya. Sedangkan bila berupa cair maka HC akan membentuk semacam kabut minyak, bila berbentuk padatan akan membentuk asap yang pekat dan akhirnya menggumpal menjadi debu. Berdasarkan struktur molekulnya, hidrokarbon dapat dibedakan dalam 3 kelompok yaitu hidrokarban alifalik, hidrokarbon aromatik dan hidrokarbon alisiklis. Molekul hidrokarbon alifalik tidak mengandung cincin atom karbon dan semua atom karbon tersusun dalam bentuk rantai lurus atau bercabang. Hidrokarbon dan oksidan fotokimia merupakan komponen polutan udara yang berbeda tetapi mempunyai hubungan satu dengan yang lain. Hidrokarbon merupakan polutan primer karena dilepaskan ke udara secara langsung, sedangkan oksidan fotokimia berasal dari reaksi-reaksi yang melibatkan hidrokarbon baik secara langsung maupun tidak langsung. Masalah yang dihadapi karena adanya polusi hidrokarbon harus mempertimbangkan juga adanya polusi oksidan fotokimia. Diunduh dari : http://ultrawomen.wordpress.com/…... 9/11/2012

  38. GANGGUAN KESEHATAN AKIBAT NOx • Short-term exposure at concentrations greater than 3 parts per million (ppm) can measurably decrease lung function. • Concentrations less than 3 ppm can irritate lungs. • Concentrations as low as 0.1 ppm cause lung irritation and measurable decreases in lung function in asthmatics. • Long-term lower level exposures can destroy lung tissue, leading to emphysema. • Children may also be especially sensitive to the effects of nitrogen oxides. Noxious Air Pollutants Air pollution is putting many things in the air that we’re not supposed to breathe. Among the most noxious air pollutants are nitrogen oxides, highly reactive gases containing nitrogen and oxygen, collectively known as NOx. DIUNDUH DARI: http://www.onewalloneworld.com/bulletin.php..

  39. Where are nitrogen oxides involved in atmospheric processes? We find NOx (= NO + NO2) and other nitrogen oxides nearly everywhere in atmospheric chemistry. During the night, nitrate radicals NO3 are formed and are the most active oxidants. Radicals are chemical species, which are very instable and usually react extremely fast.If N2O5 is formed in polluted areas, it can react on droplets or wet surfaces with water and nitric acid HNO3 is formed. HNO3 contributes to the acid character of the rain. Nitric acid, which can also be formed during the day by oxidation of NO2, is the main way how nitrogen oxides are removed again from the atmosphere, either by dry or by wet deposition (wash out by rain).Nitric acid is also part of polar stratospheric clouds. Nitric acid tryhydrate forms the particles on which the ozone hole developed DIUNDUH DARI: http://alchemistviolet.blogspot.com/2010/12/nox.html..

  40. EFEK LAINNYA • Oxides of nitrogen, in the presence of sunlight, can also react with hydrocarbons, forming photochemical oxidants or smog. • Also, NOx is a precursor to acidic precipitation, which may affect both terrestrial and aquatic ecosystems. HUJAN ASAM Acid rain is a popular term for the atmospheric deposition of acidified rain, snow, sleet, hail, acidifying gases and particles, as well as acidified fog and cloud water. The increased acidity of these depositions, primarily from the strong acids, sulfuric and nitric, is generated as a by-product of the combustion of fossil fuels containing sulfur or nitrogen, especially  electrical utilities (power plants.) Several processes can result in the formation of acid deposition. Nitrogen oxides (NOx) and sulfur dioxide (SO2) released into the atmosphere from a variety of sources call fall to the Earth’s surface simply as dry deposition. This dry deposition can then be converted into acids when these deposited chemicals interact with water. Most wet acid deposition occurs when nitrogen oxides (NOx) and sulfur dioxide (SO2) are converted to nitric acid (HNO3) and sulfuric acid (H2SO4) through oxidation and dissolution in the atmosphere. Wet deposition can also form when ammonia gas (NH3) from natural and agricultural sources is converted into ammonium (NH4). DIUNDUH DARI: http://www.eoearth.org/article/Acid_rain ..

  41. EFEK LAINNYA • Seriously injure vegetation at certain concentrations. Effects include: • Bleaching or killing plant tissue. • Causing leaves to fall. • Reducing growth rate. • Deteriorate fabrics and fade dyes. • Corrode metals (due to nitrate salts formed from nitrogen oxides). • Reduce visibility. Oxides nitrogen NOx may affect plants in three ways: direct contact with plants; through formed in the air, acid rain; indirectly - By the photochemical formation of oxidants such as ozone and PAN. Direct NOx impact on plants is determined visually by yellowing or browning leaves and needles, what is happening as a result of oxidation of chlorophyll. Oxidation fatty acids in plants, occurring simultaneously with the oxidation of chlorophyll, in addition, leads to the destruction of membranes and necrosis. Formed in this in cells nitrous acid has a mutagenic effect. Negative biological effects of NOx on the plants shown in the bleaching of leaves, wilting of flowers, fruiting and cessation of growth. This action is explained formation of acids when dissolved nitrogen oxides in the intercellular and intracellular fluid. Botany believe that the initial symptoms of damage to plants nitrogen oxides manifest themselves in a chaotic distribution of bleaching stains gray-green shade. These spots gradually coarse, dry out and become white. Oxides nitrogen are toxic at a concentration of 3 million-1. For comparison: sulfur dioxide is affected plants at higher concentrations (5 M-1). Violations growth of plants under the influence of NO2 are observed at concentrations of 0.35 mg/m3 and above. This value is the maximum concentration. The risk of damage vegetation nitrogen dioxide exists only in large cities and industrial areas, where the average concentration of NO2 is 0,2 - 0,3 mg/m3. Plants more stable (compared to humans) to the effect of pure dioxide nitrogen. This is due to the peculiarities of assimilation NO2, which is restored chloroplasts and a NH2-group is included in the amino acids. At concentrations 0,17 - 0,18 mg/m3 oxides of nitrogen used by plants as fertilizer. This ability to metabolizirovaniyu NOx man not inherent.

  42. Sulfur Dioxide Ninety-five percent of pollution related sulfur oxide emissions are in the form of sulfur dioxide (SO2), a heavy, colorless gas with an odor like a struck match. This gas combines easily with water vapor, forming aerosols of sulfurous acid (H2SO3), a colorless, mildly corrosive liquid. This liquid may then combine with oxygen in the air, forming the even more irritating and corrosive sulfuric acid (H2SO4). Anthropogenic SO2 is almost exclusively formed during the combustion of fossil fuels with relevant sulphur content and most important is coal because the sulfur content of liquid and gaseous fossil fuels can be easily removed before combustion.

  43. Other sulfur-containing compounds • Hydrogen sulfide (H2S) gas - rotten eggs. • Mercaptans - skunk spray or decayed garbage. (Added in trace amounts to natural gas, providing a leak-detecting warning odor.) Note: The amount of SO2 released from coal fired power plants depends on the sulfur content of coal, normally 0.7% to 2% by weight. High sulfur coal sometimes contains as much as 6% sulfur by weight. In India, sulfur content is quite low. Illustration of the important reaction pathways connecting SO, SO2, SO3 and H2SO4.

  44. EFEK KESEHATAN AKIBAT SOx • Sulfur dioxide not only has a bad odor, it can irritate the respiratory system. • Exposure to high concentrations for short periods of time can constrict the bronchi and increase mucous flow, making breathing difficult. • Children, the elderly, those with chronic lung disease, and asthmatics are especially susceptible to these effects. DIUNDUH DARI: ..

  45. EFEK KESEHATAN AKIBAT SOx • Immediately irritate the lung and throat at concentrations greater than 6 parts per million (ppm) in many people. • Impair the respiratory system's defenses against foreign particles and bacteria, when exposed to concentrations less than 6 ppm for longer time periods. • Apparently enhance the harmful effects of ozone. (Combinations of the two gases at concentrations occasionally found in the ambient air appear to increase airway resistance to breathing.) DIUNDUH DARI: ..

  46. EFEK KESEHATAN AKIBAT SOx • Sulfur dioxide tends to have more toxic effects when acidic pollutants, liquid or solid aerosols, and particulates are also present. (In the past, thousands of excess deaths occurred in areas where SO2 concentrations exceeded 1 ppm for a few days and other pollutants were also high.) Effects are more pronounced among mouth breathers, e.g., people who are exercising or who have head colds. These effects include: • Health problems, such as episodes of bronchitis requiring hospitalization associated with lower-level acid concentrations. • Self-reported respiratory conditions, such as chronic cough and difficult breathing, associated with acid aerosol concentrations. (Asthmatic individuals are especially susceptible to these effects. The elderly and those with chronic respiratory conditions may also be affected at lower concentrations than the general population.) • Increased respiratory tract infections, associated with longer term, lower-level exposures to SO2 and acid aerosols. • Subjective symptoms, such as headaches and nausea, in the absence of pathological abnormalities, due to long-term exposure.

  47. Efek SOx pada Tumbuhan • Sulfur dioxide easily injures many plant species and varieties, both native and cultivated. Some of the most sensitive plants include various commercially valuable pines, legumes, red and black oaks, white ash, alfalfa and blackberry. The effects include: • Visible injury to the most sensitive plants at exposures as low as 0.12 ppm for 8 hours. • Visible injury to many other plant types of intermediate sensitivity at exposures of 0.30 ppm for 8 hours. • Manfaat positif pada konsentrasi rendah, dirasakan oleh beberapa jenis tumbuhan pada tanah-tanah yang defisien belerang.

  48. EFEK LAINNYA Increases in sulfur dioxide concentrations accelerate the corrosion of metals, probably through the formation of acids. (SO2 is a major precursor to acidic deposition.) Sulfur oxides may also damage stone and masonry, paint, various fibers, paper, leather, and electrical components. Peningkatan konsentrasi SO2 juga dapat mengganggu penglihatan (visibility).
