Geography tion, resulting in a solution of sulfuric acid (H SO ) and ferrous sulphate (FeSO ), highly polluting. These substances acidify the water, increasing the sulphate content (sulfur ion bonded to four oxygen atoms: SO ) which cause a series of chemical reactions as, for example, the solubility (ability of a substance to dissolve in another) heavy metals, calcium, sodium, iron and others. The oxidation (oxidation is loss of electrons by a chemical species) of the sulfide can also generate heat and induce spontaneous combustion of coal, releasing hydrogen sulfide (H S), which has very unpleasant smell, and that cause acid rain, many times, the dynamics of the atmosphere occur in areas far from polluting the area, ie, its consequences can reach companies that have no direct relation to the holding area, not respecting boundaries. This is a type of smog pollution composed of soot and sulfur. In 1952, in London, over three thousand people died in a few days due to the increased concentration of pollutants that have accumulated, trapped in an air mass that remained parked due to a temperature inversion. ACTIVITY Have you ever heard of any fact related to this pollution invasive borders? Thinking about this issue, if an industry polluting the air were installed in your town that care would be needed to define the location of this industry without it pollute its atmosphere? Until the 1970s, all tailings from coal mining, were open. From the 1980s, there are the first steps in trying to minimize the environmental impacts of this exploitation. Studies are being conducted for the development of clean technologies for coal use, trying to minimize the environmental impacts and achieving greater energy efficiency. This process can be performed by means of pre-combustion, during combustion and post-combustion or by conversion of coal into other fuels. That perform such a search for better understanding of these processes? Stop Dreaming of a Car!

Geografija tion, što je rezultiralo u otopini sumporne kiseline (H SO ) i željezni sulfat (FeSO ), vrlo zagađuje. Te tvari kiseliti vodu, povećanje sadržaja sulfata (sumpora ionska prešano četiri atoma kisika: SO ) koji uzrokuju niz kemijskih reakcija kao, primjerice, topljivosti (sposobnosti tvari da raspusti u drugoj) teških metala, kalcija, natrija, željeza i drugih. Oksidacije (oksidacija je gubitak elektrona od kemijske vrste) od sulfid također mogu generirati toplinu i izazvati spontano izgaranje ugljena, objavljivanju sumporovodik (H S), koji ima vrlo neugodan miris, i da kiša uzrokuju kiselina, mnogi puta, dinamika atmosferi javljaju u područjima daleko od zagađuju prostor, odnosno, njegove posljedice može doći do tvrtki koje nemaju izravan odnos na pritvor, ne poštujući granice. To je vrsta zagađenja smogom sastavljenom od čađi i sumpor. Godine 1952, u Londonu, više od tri tisuće ljudi poginulo je u nekoliko dana zbog povećane koncentracije onečišćujućih tvari koji su se nakupili, zarobljeni u zračnoj masi koja je ostala parkiran zbog temperaturne inverzije. AKTIVNOST Jeste li ikada čuli za bilo koje činjenice vezane uz ovo zagađenje invazivnih granica? Razmišljajući o tom pitanju, ako se industrija zagađuje zrak su instalirani u vašem gradu koji skrbi će biti potrebno definirati položaj ove industrije, bez da zagađuju svoju atmosferu? Do 1970-ih, sve pljeva iz rudnika ugljena, bile otvorene. Od 1980-ih, tu su prvi koraci u pokušavaju minimalizirati utjecaja na okoliš eksploatacije ove. Istraživanja se provode za razvoj čistih tehnologija ugljena za uporabu, pokušavajući smanjiti utjecaj na okoliš i postizanje veće energetske učinkovitosti. Ovaj proces može biti izvedena uz pomoć prije izgaranja, tijekom izgaranja i nakon izgaranja ili konverzije ugljena u drugim gorivima. koji obavljaju takve pretrage za bolje razumijevanje tih procesa?
