Air pollution is the presence of a strange substance or a change in weight in the air, which causes unclean air or causes fatigue, irritability, reduced vision Ơ nhiễm khơng khí có mặt chất lạ thay đổi trọng lượng phần khơng khí, làm cho khơng khí khơng gây mệt mỏi, khó chịu, giảm tầm nhìn xa Classify Primary pollutants : are usually produced from a process, such as ash from a volcanic eruption Carbon monoxide gas Sulfur dioxide Ground level ozone (O3) formed from NOx and VOCs Ozone (O3) is a key constituent of the troposphere At abnormally high concentrations brought about by human activities (largely the combustion of fossil fuel), it is a pollutant, and Secondary pollutants: a constituent of smog are not emitted directly Rather, they form in the air when primary pollutants react or interact.Ground level ozone is a prominent example of a secondary pollutant Peroxyacetyl nitrate (C2H3NO5) - similarly formed from NOx and VOCs Substances emitted into the atmosphere by human activity Nitrogen oxides, Produced Nitrogen volcanoesoxides, andhas in been various industrial Becauseemitted of its role asby a greenhouse described as is "the from agriculturalgas, it processes Ammonia a CO is a colorless, odorless, toxic yet non-irritating gas particularly nitrogen dioxide, are pollution".Carbon expelled from high Coal and petroleum often contain sulfur leading pollutant" and "the worst climate dioxide processes compound with the formula NH3 Ammonia contributes is ais temperature natural component combustion, of the atmosphere, andcombustion of are also essential produced forfuel plant during life and It a product of incomplete such as compounds, and their combustion generates sulfur significantly to the nutritional needs of terrestrial organisms given offgas, by the human respiratory system They can be seen as a thunderstorms by electric natural coal or wood.discharge dioxide by serving as a precursor to foodstuffs and fertilizers brown haze dome above or a plume downwind of cities Exercise Read the text and answer the questions: (Đọc văn trả lời câu hỏi sau: ) What is an air pollutants?
