Environmental protection - air pollution - FINE PARTICULATES ...id that is a highly reactive oxidizing agent used in the production of fertilizers, explosives and rocket fuels. Ozone is an unstable oxidizing agent, poisonous in high concentrations, ith a pugent, irritating odour. In eak concentrations, ozone is used as a bleach and to sterilize ater.In effect, breathing air containing these chemicals is like breathing diluted quantities of poison gas, acid and bleach.hat is its effectsHuman can be adversely affected both before and after the burning of fossil fuels. Before burning, fumes from evaporating petroleum fuels can be poisonous and carcirogenic in high concentrations. In addition a third group of toxical chemical by-products is subsequently formed from reactions of combustion products in the atmosphere.FINE PARTICULATESFine particulates are particles do small they remain suspended in air here they can be inhaled and deposited deep in the respiratory system. Primary fine particulates are released directly into the air drom sources such as tailpipes. Secondary dine particulates are formes from physical and chemical reactions involving gases such as Nox, Sox, and VOCs, emitted into the air.Fine particulates are associated ith respiratory syptoms, increased emergency room vicits for asthma, increased hospitalization, imapired lung function, increased absence from ork and increased death from cardiopulmonary disease and lung cancer. Children, the elderly, smokers, asthmatics and others suffering from respiratory disorders are especially vulnerable to this type of air pollution.Current research indicates that fine particulate matter is the air pollutant ith the graetest immediate health impacts- and resulting costs.As ell as causing health damage, fine particulates can lead to major reductions in visibility. Although it is difficult to put a dollar figure on the loss of visibility, it is clear British Columbians value the beauty of the environment. Recent scientific research indicates that vehicle emissions and ood smoke are the greatest caused of reduced visibility in B.C.PAGE PAGE 2mIąi 0JmHnHu0Jaj0JU5CJtmHsHCJmHsH-VlmIchshaaaa aaaaaaaaiaaa1h ą!nn77ia8i8NormalCJsHaJmHsHtHFiFHeading 1aiaaCJmHsHAiDefault Paragraph Font6i6Titleaa5CJ tmHsH, i,Footerą!iPage NumberNCiNBody Text IndentaaaaaCJmHsH,Ui1,Hyperlinkphiii!!.a0aaIJOPXYV knIą23HIIaDragosusseraDVDaDtMy DocumentstNETtREFERATEte-referatetenglezateng1tEnv ironmental protection - air pollution.doci9iIiPiUnknonaGaaz Times Ne Roman5Symbol3z Arial0akga!an203HENVIRONMENTAL PROTECTION AIR POLLUTIONDragosusser...
